Comparison of Single-Stage and Dual-Stage Approaches for Nonunion Repair in the Absence of Evident Infections

OBJECTIVE: This study aimed to determine if routine dual-stage nonunion repair (DSR) surgery lead to better outcomes than single-stage nonunion (SSR) repair surgery in fracture nonunions without evident clinical or laboratory signs of infection. METHODS: Design: Retrospective comparison study Setting: Level One Trauma Center affiliated with an academic teaching hospital Patient selection Criteria: Skeletally mature patients diagnosed with fracture nonunion between June 2013 and January 2022 were included. Patients with previous non-operative treatment, definitive external fixation, previous or current diagnosis of FRI, or less than 12 months of follow-up were excluded. Outcome measures and comparison: Patient characteristics and details of the primary and the revision surgery were recorded. Comparison of the primary outcome measures - FRI, recalcitrant nonunion, and implant failures were performed between SSR and DSR groups RESULTS: A total of 113 patients met the eligibility criteria. Eighty-six patients (mean age 44.8 years, range – 17 – 80 years, 64 percent males) underwent SSR, while 27 patients (mean age 50.8 years, range 21-77 years, 52 percent males) underwent DSR. Seventy six percent underwent SSR and 24 percent underwent DSR. Baseline characteristics were similar between groups (open fractures, p=0.918; smoking, p=0.86; lower limb fractures, p=0.238; Diabetes, p=0.503; ESR, p=0.27; CRP, p=0.11; age, p=0.11; CCI, p=0.06) except for a higher rate of DSR in cases initially treated elsewhere (p = 0.015) and in obese patients (p=0.044). Bone grafting was more frequent in DSR using plates (p = 0.030). No significant differences were observed in subsequent infections (6.97 % vs 7.41 %, p=0.939), persistent nonunion (28.2 % vs 14.81 %, p=0.169), or implant failure (19.76 % vs 22.22 %, p=0.782) between SSR and DSR. CONCLUSION: No difference was found in infection, recalcitrant nonunion, and implant failure between single stage repair and dual stage repair for nonunions without overt signs of infection. The study challenges the routine use of DSR, questions the necessity of subjecting patients to two surgical procedures, and advocates for a more judicious approach in the absence of overt FRI in a fracture nonunion.

Prior Antidepressant Prescription is Associated with Greater Opioid Prescriptions and Complications in Cervical Spine Surgery

Study Design: Retrospective cohort study of national database. Objective: This study evaluates the impact of antidepressant prescriptions on postoperative outcomes and complications in cervical spine surgery. Summary of Background Data: Patients who underwent cervical spine surgery often receive antidepressant prescriptions (ADP) to address concurrent mental health issues such as depression and anxiety. However, the use of antidepressants can affect bone metabolism. Yet, there is an opacity in the literature regarding the effects of ADP on outcomes of cervical spine surgery. Methods: Utilizing the TriNetX database, ACDF and Cervical Arthroplasty patients were matched on a 1:1 basis according to ADP status. Outcome variables such as emergency department visits, hospital readmissions, opioid prescription, and misuse, pseudoarthrosis, adjacent segment disease, and hardware failure were evaluated over follow-up periods ranging from 2 to 24 months. Results: In a matched sample of 12,838 patients, those with ADP exhibited significantly higher rates of opioid prescriptions at 2 weeks (OR 1.34, P<0.0001), 6 months (OR 1.36, P<0.0001), 12 months (OR 1.36, P<0.0001), and 24 months (OR 1.33, P<0.0001). Emergency Department visits were significantly higher at 6 months (OR 1.11, P=0.0082) and 24 months (OR 1.083, P=0.014). Opioid abuse is notably higher by 24 months (OR 1.37, P=0.0033). Hospitalization rates were significantly increased at 12 months (OR 1.16, P=0.0013) and 24 months (OR 1.18, P<0.0001). Adjacent segment disease (OR 1.54, P<0.0001 at 24 mo), hardware failure (OR 1.42, P=0.013 at 24 mo), and pseudarthrosis (OR 1.48, P<0.0001 at 24 mo) were also significantly higher in the ADP group. Conclusions: Patients with ADP undergoing cervical spine surgery experience higher risks of opioid use and abuse, increased hospital readmissions, emergency department visits, and a higher rate of mechanical complications.

Pediatric Scaphoid Nonunions: Does Insurance Status Play a Role?

Objective: There are no studies that evaluate the effects that insurance or socioeconomic status may have on treatment and outcomes of scaphoid nonunions in children. We evaluated whether there is an association between insurance status and (1) time from injury to hand surgeon evaluation, (2) time from specialist evaluation to surgery, and (3) postoperative outcomes of scaphoid fracture nonunions in children. Methods: A chart review was performed for patients who underwent surgical treatment of scaphoid fracture nonunion from January 2015 and April 2021 at a large tertiary care pediatric hospital. Underinsured patients were defined as those with no medical insurance or Medicaid/state-funded insurance. Results: There were 21 privately insured patients and 17 patients who were underinsured. There was no difference in age, race, or fracture characteristics between the two groups. The mean time between injury and hand surgeon evaluation was 192 SD 195 days for the privately insured group compared with 155 SD 205 days for the underinsured group (P = 0.57). The mean time between specialist evaluation and surgical treatment was 35 SD 54 days for the privately insured group and 31 SD 31 days for the underinsured group (P = 0.82). Union was achieved in 80% of patients with private insurance compared with 88% of underinsured patients after primary surgery (P = 0.67). There was no difference detected in the proportion of patients who had residual pain (15% vs 19%), range of motion deficits (38% vs 40%), strength deficit (6% vs 7%), and return to activity (94% vs 93%) between privately insured and underinsured patients, respectively (P = 1.00). Conclusions: There was no difference in time from injury to specialist evaluation, time from evaluation to surgery, or postoperative outcomes based on insurance status for pediatric patients with scaphoid fracture nonunions. Although insurance status was not associated with access to care for pediatric scaphoid fracture nonunions at our institution, this information may not be generalizable to other populations, including patients who sustain primary scaphoid fractures and who have not yet developed nonunions. Level of Evidence: Level III—retrospective cohort study.

Guidelines for the design and implementation of youth participation initiatives to safeguard mental health and wellbeing.

Worldwide, young people are increasingly engaged in participation and decision-making initiatives regarding issues that affect their lives through advisory groups, representative councils, advocacy and activism. Emerging evidence suggests that these initiatives may have an impact on the mental health and wellbeing of the youth involved. These guidelines, which are based on a scoping review of global evidence and led by a youth advisory group with lived experience of participation initiatives, summarise evidence-based recommendations for designing and implementing youth participation initiatives that protect the mental health and wellbeing of the young people involved. Development of these guidelines followed methods outlined by the Appraisal of Guidelines for Research and Evaluation (AGREE) instrument and the strength of the evidence behind each recommendation was aligned with the National Health and Medical Research Council Levels of Evidence and recommendation grading system. The guidelines include 20 recommendations and three good practice recommendations, addressing the following areas: prioritising clear and respectful communication; creating safe and flexible practices for young people; facilitating social and emotional support; empowering young people to participate in meaningful and impactful ways; and supporting young people to develop skills. These guidelines are expected to provide cross-sectoral, global groups with the confidence to design and implement youth participation initiatives, using the best-available evidence, in ways that safeguard the mental health of the participating young people.

Comparative Analysis of Full Endoscopic Interlaminar Lumbar Discectomy and Lumbar Microdiscectomy

Study Design: Retrospective clinical study. Objectives: The aim is to assess and contrast the results of full endoscopic lumbar discectomy (FELD) and lumbar microdiscectomy (LMD) for L5–S1 disc herniation, with a specific emphasis on postoperative pain reduction and surgical effectiveness. Background: Although minimally invasive spine operations are becoming more popular, there is still little research on the comparative effectiveness of FELD and LMD. Materials and Methods: The research had a total of 50 patients who received surgical intervention for L5–S1 disc herniation, with 25 patients getting full endoscopic interlaminar discectomy and the other 25 patients undergoing LMD. Clinical outcomes were assessed using the Visual Analog Scale for low back and leg pain, collected preoperatively and at the end of 1 week, 3 months, and 6 months postsurgery. Patient satisfaction was evaluated using Odoms criteria at the same intervals. Results: The study included 50 patients (26 men, 24 women), with a mean age of 51.11 ± 13.76 years. The groups had no significant differences in demographic data. Back and leg pain Visual Analog Scale scores decreased more significantly in the FELD group after 1 week of surgery (P < 0.001), although the declines at 3 months and 6 months were not significantly different between the two groups. According to Odoms criteria, patient satisfaction was favorable in both groups and significantly better in the FELD group than in the LMD group at 1 week postoperatively [excellent in 20 patients (80%) in the FELD group vs 9 patients (36%) in the LMD group (P = 0.025)]. However, patient satisfaction at 3 months and 6 months did not differ between the groups. Conclusion: This study demonstrates that FELD offers significant early postoperative advantages over LMD at the L5–S1 level when compared with pain and satisfaction scales.

Workplace-based prevention and management of knee pain: a systematic review.

Knee pain is highly prevalent and disabling among the general and working population. This systematic review explored the effectiveness of workplace-based interventions on knee pain among workers. A PICO-guided systematic search was performed in PubMed and Web of Science Core Collection for articles published from 2003 until January 2023. Eligible articles included randomized and non-randomized controlled trials assessing the effect of workplace-based interventions on knee pain among currently employed adult workers. The quality assessment and evidence synthesis adhered to the systematic review approach, which the Institute for Work & Health developed, and was focused on developing practical recommendations for stakeholders. Of the 13 identified studies, 11 medium- and high-quality studies were entered into the evidence synthesis. Importantly, none of the included studies specifically aimed at reducing of knee pain. Still, among the included studies, a strong level of evidence suggested no benefit of workplace-based physical exercise/activity intervention on knee pain. The level of evidence was deemed too uncertain to guide current policy/practices for ergonomic and multifaceted interventions. No intervention types were associated with negative effects on knee pain. The current evidence-base pertaining to workplace-based prevention and management of knee pain is insufficient to guide effective preventive workplace practice or policy development. Considering the global prevalence and health impact of knee pain, development and implementation of effective workplace interventions aimed at prevention and management of knee pain is needed.

MOBILE APPLICATIONS AND SUICIDE: A SYSTEMATIC ANALYSIS ON THE EFFECTIVENESS OF MOBILE APPLICATIONS FOR SUICIDE PREVENTION

MOBILE APPLICATIONS AND SUICIDE: A SYSTEMATIC ANALYSIS ON THE EFFECTIVENESS OF MOBILE APPLICATIONS FOR SUICIDE PREVENTION ABSTRACT Objective: This study aimed to evaluate the effectiveness of mobile applications designed to prevent suicide. Design: Within the scope of the study, open access Turkish and English articles published in online databases (Web of Science, PubMed (MEDLINE), WİLEY, Taylor & Francis Online, Science Direct) between 2019 and August 2024 were reviewed. Randomized controlled trials on mobile applications whose role in preventing suicide was clearly stated in the articles were included in the study. Results: As a result of the screening, seven studies that met the inclusion criteria were included in this study. In four of the included studies, a routine intervention (awareness training, psychotherapy or medical treatment) was compared with an additional mobile application; in three studies, a routine intervention was compared with a mobile application. As a result of the evaluation, different results were obtained in terms of the effectiveness, acceptability and usability of mobile applications. It was concluded that mobile applications with psychotherapy content, especially applied together with face-to-face interventions, provided more positive results in reducing the risk of suicide. However, the level of effectiveness may vary depending on the content of the application, the characteristics of the sample, and whether it is a treatment support. At the same time, it has been determined that mobile applications are usable but that there is limited data on their acceptability. Conclusion: Mobile applications aimed at preventing suicide are potential tools that can be used in preventing suicide. However, there is no definitive result regarding their effectiveness. It is important to increase randomized controlled studies with a large sample, long follow-up period, and high level of evidence. Keywords: Mental health, mobile application, suicide

The effect of vitamin D on the speed and quality of pediatric fracture healing

Purpose: To evaluate the effect of vitamin D on the speed and quality of pediatric fracture healing. Methods: A 4-year prospective study of healthy children with shaft fractures of the forearm bones (treated with minimally invasive osteosynthesis) or femur (treated by traction or by minimally invasive osteosynthesis). All children had their vitamin D levels examined four times—at the time of the injury, 1, 3, and 5 months after the injury. Also, all children underwent radiograph follow-ups (same time as blood tests) to evaluate fracture healing. Children were, in the beginning, blindly divided into two similarly sized groups—one group was orally administered cholecalciferol throughout the follow-up, the second group was not, and we compared those groups. Results: Altogether, 63 children were included in the study—36 supplemented and 27 non-supplemented. In supplemented children, the vitamin D levels increased statistically significantly during the follow-up period, in contrast to the non-supplemented group. The fracture healing on radiographs was also statistically significantly faster and better in the supplemented group. When we divided children according to fracture type, we observed statistically significantly better fracture healing in children with forearm fractures in the supplemented group for the whole study period. In children with femoral fractures, the healing in the supplemented group was statistically significantly better after 3 months; however, after 1 and 5 months, the difference was not statistically significant. Conclusions: Based on our results, we recommend vitamin D testing and administration for children treated for forearm and femoral fractures. Level of evidence: Level I.

Association Between Insufficient Restoration of Meniscal Tension During Surgical Repair of Medial Meniscus Root Tear and Surgical Outcomes: Clinical Implication of Curtain-Cliff Sign.

Despite the clinical benefits over nonoperative treatment or meniscectomy, the clinical outcomes of surgical repair for medial meniscus posterior root tear (MMRT) remain suboptimal, which may be attributed to the insufficient restoration of meniscal hoop tension during surgery. To analyze the clinical outcomes of surgical repair of MMRT based on the appearance of the meniscal tension observed immediately after surgery. Cohort study; Level of evidence, 3. Electronic medical records of patients who underwent arthroscopic transtibial pull-out repair of MMRT between 2010 and 2021 were retrospectively reviewed. Patients with at least a 2-year follow-up and whose overall meniscal status after the surgical repair could be evaluated via arthroscopic images or videos were eligible to be included. Patients were classified based on the presence of the curtain-cliff sign, potentially implying insufficient postoperative meniscal hoop tension (group 1, patients without the curtain-cliff sign; group 2, patients with the curtain-cliff sign). Regression analysis was performed to evaluate whether the curtain-cliff sign reflects postoperative meniscal extrusion. Subsequently, comparative analyses were conducted between the 2 groups regarding baseline demographic data, clinical scores, intraoperative data, and radiologic parameters. A total of 79 patients were included (group 1, 59 patients; group 2, 20 patients). Regression analysis revealed a significant association between the curtain-cliff sign and postoperative meniscal extrusion, suggesting its potential to reflect the postoperative meniscal tension. In the between-group comparisons, there were no differences in baseline demographic data, preoperative clinical scores, and preoperative radiologic variables. However, at the final follow-up, group 2 showed a significantly lower International Knee Documentation Committee subjective score compared with group 1 (group 1, 61.7 ± 14.4; group 2, 52.9 ± 12.5; P = .017), while no significant differences were found in the visual analog scale for pain score and Lysholm score. Additionally, group 2 exhibited significantly higher postoperative meniscal extrusion compared with group 1, which was measured at both the midpoint of the medial femoral condyle (group 1, 4.0 ± 1.1 mm; group 2, 5.1 ± 1.5 mm, P = .004) and the posterior border of the medial collateral ligament (group 1, 4.4 ± 1.2 mm; group 2, 5.7 ± 1.5 mm; P = .004), with more pronounced progression compared with the preoperative status at these sites. Consistently, the progression of both the osteoarthritis grade and the hip-knee-ankle angle compared with preoperatively was significantly greater in group 2. In patients in whom the restoration of meniscal tension appears insufficient immediately after surgical repair of MMRT, relatively poor clinical outcomes can be anticipated. The findings of this study suggest that efforts to reinforce meniscal tension may be required during surgical repair of MMRT in some cases, especially those showing the curtain-cliff sign.

Sling Results in Better Sleep Quality and Less Anxiety Early After Arthroscopic Rotator Cuff Repair: A Randomized Single-Blinded Trial.

Sleep disturbance is commonly reported by patients wearing an abduction brace after arthroscopic rotator cuff repair (ARCR). Although a sling has been proven noninferior to an abduction brace for function and repair integrity, there is no evidence-based medical support for the advantage of the sling in improving sleep quality compared with a brace. This study aimed to compare the effects of a sling and an abduction brace on sleep quality and clinical outcomes after ARCR. It was hypothesized that immobilization in a sling would result in better sleep quality while not deteriorating clinical outcomes and bone-tendon healing compared with an abduction brace. Randomized controlled trial; Level of evidence, 1. A total of 142 consecutive patients with rotator cuff tears were randomly assigned to 2 groups: (1) the brace group, receiving abduction brace immobilization for 6 weeks, and (2) the sling group, receiving sling immobilization after ARCR for 6 weeks. The primary outcome was the Pittsburgh Sleep Quality Index at 6 weeks postoperatively. Secondary outcomes-American Shoulder and Elbow Surgeons score, Self-rating Anxiety Scale, pain, satisfaction, and tendon healing (using ultrasonography)-were evaluated until 1 year postoperatively. Complete outcome measurements were obtained for 131 patients. The Pittsburgh Sleep Quality Index at 6 weeks was 11.1 ± 2.7 for the brace group and 9.2 ± 2.3 for the sling group (P < .001), indicating a statistically significant advantage for the sling group. The sling group also reported significantly lower Self-rating Anxiety Scale, lower pain level, and higher satisfaction scores at 6 weeks. No significant difference was observed in outcome measures between groups at 1 year. The tendon healing rates (91% vs 88%, respectively) were comparable between the brace and sling groups within the first 1 year (risk ratio, 1.03 [95% CI, 0.92-1.16]; P = .59). The use of a sling resulted in better sleep quality, less anxiety, and higher satisfaction compared with an abduction brace in the first 6 weeks after ARCR; nevertheless, functional outcomes and repair integrity were similar at 1 year postoperatively between the 2 groups. These findings indicate that a sling is appropriate for the postoperative care of ARCR. However, caution should be used when interpreting these results because the clinical relevance of sling-related benefits warrants further investigation.

Evaluation of Preoperative Factors That Affect the Alpha Angle of Screw Insertion After the Open Latarjet Procedure.

The open Latarjet procedure yields excellent results as a treatment for anterior shoulder instability. The position of the bony fragment and the insertion angle of the screw (the alpha angle) are critical factors for a successful procedure. The alpha angle is considered overangulated at >25°, which is associated with poor bone fixation and healing. To assess preoperative patient anatomic factors that affect the alpha angle in the Latarjet procedure for anterior shoulder instability. Case-control study; Level of evidence, 3. In this retrospective study, 76 patients who underwent the open Latarjet procedure between October 2009 and December 2023 were included. Postoperative computed tomography scans were reviewed for the alpha angle, and patients were classified into 2 groups: group 1 (alpha angle ≥25°) and group 2 (alpha angle <25°). Preoperative patient characteristics and radiological parameters obtained from preoperative computed tomography scans were analyzed and compared between groups 1 and 2. We developed a novel method to measure the depth of the chest and the angle between the deltopectoral interval and the plane of screw insertion. We also measured the thickness of the pectoralis major and subscapularis muscles. Of the 76 patients in this study, 41 and 35 patients were included in groups 1 and 2, respectively. The mean alpha angles of groups 1 and 2 were 36° and 12°, respectively, and the body mass index was significantly higher in group 1 (P < .001). In addition, group 1 had a significantly longer distance from the anterior edge of the glenoid to the skin margin of the deltopectoral interval (P < .001). The angle between the deltopectoral interval and the plane of screw insertion (traction angle) was significantly larger in group 1 (P < .001), and the pectoralis major and subscapularis muscles were thicker in group 1 (P = .017 and P = .032, respectively). The alpha angle after the Latarjet procedure was strongly related to the patient's weight, body mass index, depth of the chest, and the angle between the deltopectoral interval and the plane of screw insertion. To our knowledge, this is the first study in which the preoperative factors that facilitate proper screw fixation in the Latarjet procedure are reported.

Treatment and Early Outcomes of Capitellar Osteochondritis Dissecans.

Treatment for osteochondritis dissecans (OCD) of the humeral capitellum has been predominantly guided by fragment stability and articular cartilage integrity. Nonoperative management is recommended for stable lesions, whereas surgical intervention is indicated for unstable lesions and those that fail nonoperative care. Several surgical options may be considered, although limited information is available regarding indications for specific surgical techniques and comparative postoperative results. To assess surgical outcomes of patients with capitellar OCD treated according to a decision-making approach focused on subchondral bone involvement. Cohort study; Level of evidence, 3. Patients diagnosed with capitellar OCD at a tertiary academic center were enrolled in a prospective longitudinal cohort study. Patient information was collected at the time of enrollment, and OCD lesions were classified according to the Nelson grade. Clinical and radiologic data were collected both pre- and postoperatively for those undergoing surgical treatment. Surgical procedures were performed based on an evolving treatment framework that included considerations specifically for lesion containment and depth of subchondral bone disease. Timmerman scores were obtained to assess patient functional outcomes. A total of 154 patients were prospectively enrolled, 19 of whom had bilateral disease. The mean age at presentation was 13.7 years; 39% were gymnasts and 28.5% were primary baseball or softball athletes. Surgery was performed on 145 elbows, including 43 drilling/microfracture procedures, 21 internal fixations, and 63 autologous osteochondral grafting (OG) procedures. Clinically, there were significant improvements in pain, elbow motion, and mechanical symptoms. Timmerman scores significantly improved after each type of surgical procedure. A total of 76% of patients returned to their primary sport. When stratified by the Nelson grade, patients with OG had lower revision surgery rates than those treated with drilling/microfracture and fixation. Furthermore, for Nelson grade 2 lesions, patients treated with OG had significantly better postoperative elbow motion and higher Timmerman scores compared with those treated with other procedures. Using a treatment framework incorporating lesion containment and depth of subchondral bone disease, surgery for capitellar OCD provides clinical, radiologic, and functional improvements. Patients treated with OG may have lower revision rates and better functional outcomes compared with those treated with other surgical techniques, with OG warranting consideration even for lower-grade OCD lesions.

WOUND MANAGEMENT, HEALING, AND EARLY PROSTHETIC REHABILITATION: PART 1 - A SCOPING REVIEW OF HEALING AND NON-HEALING DEFINITIONS

BACKGROUND: Following lower limb amputation, timely prosthetic fitting enhances mobility and quality of life. However, inconsistent definitions of surgical site healing complicate prosthesis readiness assessment and highlight the need for objective wound management measures. OBJECTIVE: This review aimed to compile definitions of healing and non-healing provided in the literature investigating biomarkers of healing of the tissues and structures found in the residual limbs of adults with amputation. METHODOLOGY: A scoping review was conducted following JBI and PRISMA-ScR guidance. Searches using “biomarkers,” “wound healing,” and “amputation” were performed on May 6, 2023, on Web of Science, Ovid MEDLINE, Ovid Embase, Scopus, Cochrane, PubMed, and CINAHL databases. Inclusion criteria were: 1) References to biomarkers and healing; 2) Residuum tissue healing; 3) Clear methodology with ethical approval; 4) Published from 2017 onwards. Articles were assessed for quality (QualSyst tool) and evidence level (JBI system). FINDINGS: Of 3,306 articles screened, 219 met the inclusion criteria and are reviewed in this article, with 77% rated strong quality. 43% of all included sources did not define healing, while the remainder used specific criteria including epithelialization (14%), wound size reduction (28%), gradings scales (3%), scarring (1%), absence of wound complications (2%), hydroxyproline levels (0.5%), no amputation (0.5%), or neovascularization (0.5%). 84% of included sources did not provide definitions of non-healing. Studies defining non-healing used criteria like wound complications (4%), the need for operative interventions (4%), or lack of wound size reduction (1%). For 10% of included sources, healing and non-healing definitions were considered not applicable given the research content. Total percentages exceed 100% for both healing and non-healing definitions because some sources used two definition classifications, such as epithelialization and wound size reduction. The findings indicate a lack of standardized definitions irrespective of study type. CONCLUSION: This review reveals significant gaps in current definitions of healing and non-healing, often based on superficial assessments that overlook deeper tissue healing and mechanical properties essential for prosthesis use. It emphasizes the need for comprehensive definitions incorporating biomarkers and psychosocial factors to improve wound management and post-amputation recovery. Layman's Abstract After a lower limb amputation, early prosthetic fitting can significantly improve quality of life. However, different definitions of surgical site healing make deciding when a prosthetic can be used difficult. This scoping review collected and compared definitions of healing and non-healing found in research about biological markers (biomarkers) that are used for tracking residual limb healing. On May 6, 2023, searches were conducted using terms like “biomarkers,” “wound healing,” and “amputation” across several databases. Studies were included if they discussed biomarkers, focused on residual limb healing, had clear methods and ethical approval, and were published during or after 2017. Of 3,306 articles screened, 219 met the criteria, with 77% rated as high quality. 43% of the included sources did not define healing. Definitions provided included new skin growth (14%), reduction in wound size (28%), grading scales (3%), scarring (1%), no complications (2%), hydroxyproline levels (0.5%), no need for amputation (0.5%), or new blood vessel formation (0.5%). 84% of sources did not define non-healing, with the remainder based on healing complications (4%), the need for more surgery (4%), or no reduction in wound size (1%). In 10% of included sources healing and non-healing definitions were considered not relevant to their research. Total percentages for healing and non-healing definitions exceeds 100% because some sources used two definitions, for example, new skin growth and reduction in wound size. Overall, the review shows gaps in definitions, many of which are too basic and ignore deeper tissue healing and factors needed for prosthetic use. More thorough definitions that include the physical, mental, and social sides of healing are needed to improve recovery.

A Systematic Review to Explore the Role of Industry and Regulators on Minimally Invasive Aesthetics Education: A Tale of Two Cities.

The aesthetic medicine industry has seen significant growth due to technological advancements and increasing demand for minimally invasive procedures. This sector's influence on educational institutions is profound, often shaping curricula to align with industry standards. However, this focus can sometimes narrow educational scope, potentially compromising the broader intellectual and ethical development of medical professionals. This study employs a comprehensive literature review to examine the influence of the aesthetic medicine industry on medical education. A systematic search was conducted across academic databases including PubMed, Google Scholar, and ScienceDirect, focusing on articles published between January 2003 and December 2023. Inclusion criteria encompassed studies examining the impact of industry on medical education, financial relationships, ethical implications, and student outcomes. Out of 279 studies identified, 21 met the inclusion criteria. The analysis highlighted themes such as the need for a balanced curriculum integrating both theoretical and practical training, the impact of financial incentives on educational integrity, and the importance of ethical guidelines. The literature underscores the necessity for standardised curricula and enhanced regulatory oversight to ensure comprehensive and unbiased education. The aesthetic medicine industry's significant influence on medical education necessitates a balanced approach that integrates industry advancements with ethical and comprehensive educational practices. Addressing these challenges requires collaboration between academic institutions and industry partners, alongside stringent regulatory oversight. By ensuring educational integrity and fostering holistic training, the field can produce well-rounded professionals capable of ethical and effective practice in aesthetic medicine.

Meta-Analysis Investigating Optimal Timing of Chemoprophylaxis for Venous Thromboembolism in Operatively Managed Blunt Spinal Injuries.

Blunt spinal injuries (BSIs) are associated with substantial morbidity and mortality. Management typically involves stabilization of the spinal column and may include chemoprophylaxis for venous thromboembolism (VTE) prevention. The optimal timing of chemoprophylaxis initiation in operatively managed BSI patients remains debated. Analyze available literature on optimal chemoprophylaxis timing for the prevention of VTE in patients postinjury undergoing operative repair. Systematic review and meta-analysis. A systematic review and meta-analysis were conducted following Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. PubMed and MEDLINE were searched for studies assessing chemoprophylaxis timing in adult BSI patients. Inclusion criteria focused on operatively managed BSIs and anticoagulant usage assessment. Three studies involving 4345 patients were included. Early chemoprophylaxis initiation was associated with significantly lower deep vein thrombosis (DVT) and overall VTE incidence compared with late initiation. No significant differences were found in pulmonary embolism (PE) incidence or mortality. Early anticoagulant administration after spinal fixation for BSI reduces DVT and overall VTE risk without impacting PE incidence or mortality. Further research is recommended to solidify these findings and address existing gaps in the literature. Early chemoprophylaxis initiation in operatively managed BSI patients reduces DVT and overall VTE risk without affecting PE incidence or mortality LEVEL OF EVIDENCE: 2.

Erector spinae plane block for cancer pain relief: a systematic review.

Despite advances in pain management, cancer-related pain remains a critical issue for many patients. In recent years, there has been a growing interest in the use of fascial plane blocks, such as the Erector Spinae Plane Block (ESPB), for managing chronic pain, including in the oncology field. We conducted a systematic review to synthetize existing evidence on the use of ESPB for cancer pain management. We selected studies published between January 2016 to April 2024. A systematic search in Pubmed and Embase databases was performed. The search strategy included the following keywords and/or MeSH terms according to the controlled vocabulary of the databases sought: ((erector spinae plane block) OR (ESP block) OR (ESPB) AND ((cancer pain). We considered eligible Randomized, nonrandomized studies, case series and case reports reporting data on the use of ESPB in patients with cancer pain. The search revealed 34 studies. Among these, we found one RCT, three retrospective studies, two case series, and 28 case reports for a total of 135 patients. Studies included described the use of ESPB for the management of various types of cancer pain across different conditions, including chronic thoracic cancer-related pain, abdominal visceral pain and pain related to bone metastases. Single-shot ESPB was performed in 26 studies while continuous ESPB and the use of a peripheral nerve catheter for continuous analgesia were described in 8 studies. Neurolytic ESPB was performed in 6 studies for a total of 10 patients There was a high clinical heterogeneity in terms of technique, drugs, and use of adjuvants. The lack of comparators was a major flaw, together with the low level of evidence in the majority of the included studies. The evidence supporting the use of ESPB for cancer pain management is currently scarce, heterogeneous, and of low quality. To better understand its potential and provide robust clinical guidance, future research needs to focus on rigorous comparative studies, standardization of techniques and larger sample sizes.

Comparative Analysis of Cellulite Treatment Modalities: A Systematic Review.

Cellulite is a highly prevalent and aesthetically distressing skin condition. Whilst there are a variety of treatment modalities, none are definitively established. This systematic review aims to assess invasive and noninvasive treatment modalities for cellulite management. The review protocol was published and registered a priori (PROSPERO CRD42022359334). A comprehensive electronic search for relevant randomised controlled trials, (RCTs) was performed in CENTRAL, MEDLINE, Embase and Web of Science databases. Study quality and risk of bias were assessed using Cochrane's risk of bias tool, respectively. Overall, 753 studies were initially identified, of which 24 randomised controlled trials (RCTs) satisfied the eligibility criteria with a total of 2084 patients with a mean follow-up of 3.33 ± 13.4weeks. Evaluated interventions included mechanical stimulation, topical therapy, shock wave therapy (SWT), laser and light-based devices, radiofrequency therapy, subcutaneous injectables, and ultrasound. SWT emerged as a standout intervention, demonstrating a consistent cellulite reduction score of 2.07 ± 0.39 across four studies. Radiofrequency therapy exhibited a statistically significant reduction of thigh circumference (- 2.09cm, p < 0.001) and subcutaneous tissue thickness (- 2.23cm, p < 0.001). Subcutaneous injectables, specifically collagenase Clostridium histolyticum-aaes, demonstrated a statistically significant improvement in the clinician-reported photonumeric cellulite severity scale (17.0%) and patient-reported photonumeric cellulite severity scale (25.7%) (p < 0.001). The overall quality of the studies using the grading of recommendations, assessment, development and evaluation approach was moderate. This is the first methodologically robust systematic review evaluating interventions for cellulite. SWT, radiofrequency therapy, and subcutaneous injectables have shown promising findings in cellulite treatment. The journal asks authors to assign a level of evidence to each article.

A systematic review and meta-analysis of double trophectoderm biopsy and/or cryopreservation in PGT: balancing the need for a diagnosis against the risk of harm.

To prevent the transfer of embryos affected by monogenic conditions and/or chromosomal defects, preimplantation genetic testing (PGT) requires trophectoderm biopsy and cryopreservation. In 2-6% of biopsies, the diagnosis may be inconclusive due to DNA amplification failure or low-quality results. In these cases, a round of re-warming, re-biopsy, and re-cryopreservation is required to obtain a genetic diagnosis. In other cases, when the IVF centre starts providing PGT and/or when the patients develop an indication because of multiple failures, miscarriages or the birth of an affected child after IVF, cryopreserved untested embryos may be warmed, biopsied, and then re-vitrified. However, it is still unclear whether multiple manipulations may reduce reproductive outcomes after PGT. This study aimed at conducting a systematic review to investigate the available evidence on the safety of double biopsy and/or double cryopreservation-warming and provide recommendations in this regard. We performed meta-analyses of the differences in the reproductive outcomes (live birth per embryo transfer [LBR per ET], clinical pregnancy rate per ET [CPR per ET], and miscarriage rate per clinical pregnancy [MR per CP]) in double cryopreservation and single biopsy (CBC) or double biopsy and double cryopreservation (BCBC) flows vs the control single biopsy and single cryopreservation (BC) flow. Cryo-survival rates before ET and gestational and perinatal outcomes were also reported. PRISMA guidelines were followed to gather all available information from the literature (PubMed, Scopus, and Embase). We used Medical Subject Headings (MeSH) terms and a list of specific keywords relevant for the study question. We searched for original studies in humans, published in peer-reviewed journals in English up to April 2024. Four independent authors assessed the articles for inclusion. One included paper was retrieved from another source. A total of 4219 records were identified, and 10 studies were included in the meta-analysis. Certainty of evidence level ranged from low to moderate. Both the CBC and BCBC groups showed reduced reproductive outcomes compared to the control (BC). Specifically, live birth rates per embryo transfer were lower in the CBC group (OR: 0.56, 95% CI: 0.38-0.81, I2 = 58%; six studies) and the BCBC group (OR: 0.51, 95% CI: 0.34-0.77, I2 = 24%; six studies). CPR per ET were also lower in the CBC group (OR: 0.68, 95% CI: 0.51-0.92, I2 = 57%; seven studies) and the BCBC group (OR: 0.60, 95% CI: 0.46-0.78, I2 = 0%; seven studies). Additionally, MR per CPs were higher in both the CBC group (OR: 1.68, 95% CI: 1.02-2.77, I2 = 50%; seven studies) and the BCBC group (OR: 2.08, 95% CI: 1.13-3.83, I2 = 28%; seven studies). Cryo-survival as well as gestational and perinatal outcomes were within the expected norms in the studies reporting them. Improved genetic technologies, standardization of laboratory protocols, operators' proficiency with biopsy and cryopreservation, and continuous monitoring of the performance are essential to minimize inconclusive diagnoses and the putative impact of additional embryo manipulations. Although poorer reproductive outcomes might result from double biopsy and/or double cryopreservations, these practices may still be worthwhile to avoid transferring affected/aneuploid blastocysts. Therefore, the risks must be weighed against the potential benefits for each specific couple. PROSPERO (ID: CRD42024503678).

Research progress of three-dimensional printed customized prosthesis and its application in acetabular reconstruction of hip revision surgery

To review research progress on the design, manufacturing, and clinical application of three-dimensional (3D) printed customized prosthesis in acetabular reconstruction of hip revision surgery. The related research literature on 3D printed customized prosthesis and its application in acetabular reconstruction of hip revision surgery was searched by key words of "3D printed customized prosthesis", "revision hip arthroplasty", "acetabular bone defect", and "acetabular reconstruction" between January 2013 and May 2024 in Chinese and English databases, such as CNKI, Wanfang database, PubMed, etc. A total of 34 271 articles were included. After reading the literature titles, abstracts, or full texts, the literature of unrelated, repetitive, low-quality, and low evidence level was screened out, and a total of 48 articles were finally included for analysis and summary. The bone growth and mechanical properties of 3D printed customized prosthesis materials are better than those of non-3D printed customized prosthesis, which further solves the problem of elastic modulus mismatch between the implant and natural bone caused by "stress shielding"; the porous structure and antibacterial coating on the surface of 3D printed customized prosthesis have good anti-bacterial effect. 3D printed customized prosthesis can perfectly match the patient's individual acetabular anatomical characteristics and defect type, thus improving the accuracy of acetabular reconstruction and reducing the surgical time and trauma. 3D printed customized prosthesis can be used for precise and efficient individualized acetabular reconstruction in hip revision surgery with good early- and mid-term effectiveness. More optimized production technics and procedures need to be developed to improve the efficiency of clinical application and long-term effectiveness.

Surgical Considerations in the Management of Constriction Ring Syndrome.

Surgical management of constriction ring syndrome (CRS) is individualised due to the heterogenic presentation of the condition. CRS includes constriction rings, acrosyndactyly, nubbins and short digits. Involvement of more than one limb is common and children often need multiple surgeries. Each limb may need staged surgeries. If the child has vascular or lymphatic compromise secondary to a constriction ring, the ring needs to be excised and released in the first few days of life. The rings are released using multiple big Z-plasties in one or two stages. Nerve palsy associated with the rings need early intervention. Tendon transfers may be advised when nerve procedures like neurolysis and nerve reconstruction fail. Acrosyndactyly can be corrected with separation of the fused fingertips. At times, the web is more distal than usual and requires web deepening using partial syndactyly separation techniques and may need full thickness skin grafting. Complex type of acrosyndactyly is difficult to treat as it needs proper planning and staged surgical correction to achieve a five-digit hand. Separation of the syndactyly with web deepening gives more functional length and independence to the digits. The short fingers, especially the thumb, need reconstruction. Non-vascularised toe phalangeal transfer or a microvascular toe transfer can reconstruct a missing digit. Level of Evidence: Level V (Therapeutic).
