P59 Multicentric osteolysis nodulosis and arthropathy syndrome: a case report in Erbil - Iraq

Abstract Introduction Multicentric osteolysis nodulosis and arthropathy (MONA) is inherited in an autosomal recessive manner. At conception, each sib of an affected individual has a 25% chance of being affected, a 50% chance of being an asymptomatic carrier, and a 25% chance of being unaffected and not a carrier. Once the MMP2 pathogenic variants have been identified in an affected family member, it is a skeletal dysplasia characterized by progressive osteolysis (particularly of the carpal and tarsal bones), osteoporosis, subcutaneous nodules on the palms and soles, and progressive arthropathy (joint contractures, pain, swelling, and stiffness). Case description The patient is a 15-year-old female living in Erbil, Kurdistan. Her condition started when she was 10 months old, as she began walking and experienced recurrent sore throat. At age 4 year, she had a history of falling, developed stiffness and contracture in her elbow that made it difficult to move. A few months later, she developed a painful swelling/mass in her left foot that interfered with her walking. She had delayed tooth eruption, with only 2 teeth appearing per 2 years, her fontanelle did not close until age 3 years. At age 4, she had a fall that caused stiffness in her right hand. Over the next few years, she developed masses/swelling and pain/stiffness in her feet, hands, elbows, knees, and ankles, leading to deformities. She did not have any hearing problems but missed 3 years of school due to her condition. Back pain started 3 years ago and has been decreasing Family History: Her sister, at age 4, had pain and mild swelling in her hands and feet, along with facial abnormalities. Another 4-year-old child in the family was admitted to the ICU with similar symptoms. Complete blood count, serum biochemistry, rheumatoid profile was normal. Ultrasound of abdomen and ECHO was normal. On radiological imaging done for hands, feet, spine, in which in hands has diffuse generalized osteopenia, decrease joint spaces, resorptions of the phalanges, or cortical thinning and expansion of the phalangeal, metacarpal and metatarsal bone with deformity, and in x-ray of spine shows osteopenia with scoliosis. Dexa scan done for hip and spine which reveals (-6) severe osteoporosis. The results of genetic testing on 26th of October, led to the diagnosis of MONA syndrome. The patient was started on supportive treatment (alendronate tablet 70 mg per week, Vit D tablet 5000 IU per day, NSAID for pain and physiotherapy). Discussion The existing literature on MONA syndrome has broadly characterized the skeletal manifestations in the hands and feet. However, more detailed information is needed regarding specific skeletal involvement, ray involvement (which fingers/toes are affected), type and number of joints affected, laterality (whether the involvement is symmetrical or asymmetrical), type and severity of deformities, characteristic sparing of individual joints, if any longitudinal studies could help track the chronological order of joint involvement, especially in the larger or proximal joint Research on MONA syndrome has described the skeletal manifestations in the hands and feet, but further study is needed to understand the specifics of ray involvement, joint involvement, laterality, and severity of deformity. Longitudinal studies can help track the progression of joint involvement, particularly in larger joints. The recurrence of symptoms after orthopedic surgery in one patient highlights the progressive nature of the syndrome and suggests that early surgical intervention may not be effective. Due to the rarity of MONA syndrome, it is difficult to fully understand the pattern of the syndrome’s phenotype. Furthermore, reported correlations between the syndrome’s genetic and phenotypic characteristics have been inconsistent and inconclusive The treatment for MONA syndrome is primarily supportive and includes physical therapy to slow the development of contractures and prolong mobility. Pain relief may not be achieved through medication unless the pain is caused by secondary osteoarthritis or contractures. Additionally, daily recommended supplementation of vitamin D and calcium; standard management of congenital heart defects; management of scoliosis and kyphosis per orthopedist. Key learning points • The complicated diagnostic process for MONA syndrome necessitates a re-review of the reported phenotype-genotype correlations. By expanding the understanding of the phenotype, including the detailed skeletal manifestations, the goal is to reach a consensus on the diagnostic criteria for MONA syndrome. The aim of this case report was to systematically describe the clinical manifestations, with a focus on the skeletal features, in children with molecularly confirmed MONA syndrome, and to establish relevant phenotype-genotype correlations.

Two-Stage Flexor Tendon Reconstruction for Finger Contracture Secondary to Phlegmon: A Case Report

Flexor tendon reconstruction is a complex surgical procedure that requires great precision and specialized expertise. It remains a preferred treatment for patients with neglected lacerations of the digital flexor tendon and after the failure of flexor tendon repair. Improvements in tendon repair methods and follow-up techniques have enhanced outcomes after flexor tendon grafting. Case Presentation: A 14-year-old girl with a history of a phlegmon of the 4th finger of the right hand, treated with antibiotics and drainage. The evolution is marked after 2 years by the progressive development of a flexion contracture of the proximal interphalangeal (PIP) joint. On examination, there is a flexion attitude and an inability to extend the PIP joint without vascular or nervous disorders. A two-stage reconstruction was performed using the palmaris longus tendon as a graft. With a follow-up of 3 years, the girl has recovered complete flexion and has limited extension to 25° at the PIP joint. An arthrolysis was proposed, but the girl refused, and she is satisfied with the results.

A differentiated approach to the surgical treatment of intraarticular fracture of the proximal tibia

Background. For a long time, the question of optimal ways and methods of surgical treatment of fractures of the proximal part of the tibia (PPT) remains debatable. The purpose was to study the results of surgical treatment of fractures of the PPT using differentiated use of minimally invasive techniques. Materials and methods. The work consisted of a prospective analysis of the treatment outcomes of 87 patients who were treated 2018 to 2023. Fractures were classified according to Schatzker. The tactics of surgical treatment depended on the type of fracture, the age of the patients and the presence of concomitant diseases. A comprehensive assessment of knee function was performed using the Knee Society Score. For X-ray assessment of the degree of progression of post-traumatic arthritis, the Resnik/Niwoyama system was used. ­Results. The results of surgical treatment were studied in terms from 6 to 24 months. 19.8 % of excellent, 57.5 % good, 15.6 % sa­tisfactory and 7.1 % unsatisfactory treatment results were obtained. Progression of post-traumatic arthritis was observed in 36 patients (28 patients at one stage, 4 subjects at 2 stages and 5 patients at 3 stages). Of the complications, 7 (8.0 %) were surgical site infections, which required debridement of the focus and longer antibiotic therapy. Over time, loss of reposition and secondary displacement were identified in 5 (5.7 %) cases. The most common complications were the progression of knee osteoarthritis, the development of contractures in 11 (12.6 %) patients. Conclusions. The use of a differential approach to the surgical treatment of intra-articular fractures of PPT, based on the severity of injuries according to Schatzker, allowed to obtain positive functional results in 77.3 % of the victims. The negative consequences of intra-articular fractures of the tibial plateau that worsen the functional outcomes of treatment include the progression of knee osteoarthritis. The degree of its manifestations is largely determined by the severity of the injury, the quality of reduction, the stability of fragment fixation, and the rationality of restorative treatment and rehabilitation.

Smooth Operator: Nanotextured Breast Tissue Expanders Are Associated with Lower Rates of Capsular Contracture

Background: Continuous research on breast implant-associated anaplastic large cell lymphoma (BIA-ALCL) has introduced a focus on surface texturizations and a shift towards smooth breast devices, yet outcomes comparing the complication profiles of differently textured tissue expanders (TEs) remain conflicting. The study aim was to compare the complication profile of a new nanotextured and MRI-compatible TE to micro- and macrotextured TEs and to identify possible predictors for complications. Methods: A retrospective analysis of women undergoing expander-based breast reconstruction after mastectomy between January 2016 and March 2022 was conducted. The primary endpoint was the development of capsular contracture. Possible predictors were analyzed in a mixed-effects model using the least absolute shrinkage and selection operator (LASSO). Moreover, a comparison of complications and an evaluation of predictors were carried out. Results: A total of 147 breasts, encompassing 82 nanotextured, 43 microtextured and 22 macrotextured TEs, were analyzed. Breasts with nanotextured TEs were less likely to develop capsular contracture overall (OR, 0.12; 95%CI 0.05–0.28, p < 0.001). Post-mastectomy radiotherapy (PMRT) was identified as a predictor for capsular contracture (OR, 4.67; 95%CI 1.86–11.71, p < 0.001). Breasts with nanotextured TEs showed a higher rate of seroma, but lower rates of malposition and pain. Predictors for developing postoperative complications included higher mastectomy weight (p = 0.008). Conclusions: Breasts with nanotextured TEs exhibited the lowest rate of capsular contracture compared to micro- and macrotextured TEs. Together with its MRI-compatibility and improved oncologic follow-up, the nanotextured TE seems to be a favorable device for expander-based breast reconstruction.

Dupuytren's disease : Epidemiology, diagnosis, treatment, outcome

Dupuytren's contracture is afibroproliferative systemic disease that cannot be stopped by medication. The overall prevalence is 7-8%. Men are affected 3-4times more frequently. The cause of the disease is not known. Agenetic disposition and thus familial clustering are being discussed. Risk factors for the development of aDupuytren's contracture are work-related stress (microtrauma), nicotine and alcohol consumption, epilepsy and diabetes mellitus as well as advanced age. The prognosis is poor in cases with apositive family history, bilateral involvement, age < 50years and male gender. Several treatment options are available. Conservative therapy has no lasting benefit. Minimally invasive procedures include partial needle aponeurectomy or the injection of collagenase. Surgical procedures range from partial aponeurectomy to dermatoaponeurectomy. The recurrence risk of the gold standard treatment of surgery (partial aponeurectomy) is 20.9%.

Despite the fact that Blockchain Bitcoin technologies are both beneficial, theyare nonetheless often confused with one another. In addition, this article distinguishes between the twowith the help of the smart contract's development highlights the potential advantages of blockchaintechnology. While several research have focused on how blockchain can be used in specific contexts,neither the technology nor its potential uses have been systematically surveyed. We undertake anextensive assessment of blockchain technology, architecture, analyzes blockchain applications, technical problems to address this knowledge gap.

Zone-specific pitfalls in flexor tendon rehabilitation: management and prevention.

Despite significant advancements in flexor tendon repair techniques and rehabilitation strategies, achieving complete restoration of digital motion remains a formidable challenge. The most prevalent complications associated with tendon repair are the development of tendon adhesions and joint contractures. Left unaddressed, these complications can further lead to secondary pathomechanical changes, resulting in fixed deformities significantly affecting hand function. This review of zone-specific considerations in flexor tendon rehabilitation provides an in-depth analysis of the dynamics of tendon motion after repair and strategies to minimize common secondary complications.

A Comparison of Capsular Contracture Rates after Immediate Implant-based Breast Reconstruction Using Biologic versus Synthetic Mesh.

Capsular contracture is one of the most common reasons for reoperation after implant-based breast reconstruction. Prior investigations have suggested that biologic mesh may mitigate capsular contracture development. This study sought to compare capsular contracture rates between patients undergoing immediate implant-based breast reconstruction with biologic versus synthetic mesh. A retrospective review was conducted of the senior author's primary implant-based breast reconstructions between 2008 and 2023. Demographics and the incidence of clinically significant Baker grade III or IV capsular contractures were compared between biologic and synthetic mesh cohorts. Univariate and multivariate logistic regressions were then performed to assess potential risk factors for the development of capsular contracture. A total of 772 breasts underwent immediate reconstruction, of which 689 (89.2%) used biologic and 83 (10.8%) used synthetic mesh. Capsular contracture occurred in 15 (2.2%) biologic mesh breasts and three (3.6%) synthetic mesh breasts with no significant difference between the two groups (P = 0.430). Logistic regression showed that radiation was a borderline significant risk factor for developing capsular contracture, but the use of either biologic or synthetic mesh was not significant (P = 0.351). Biologic and synthetic meshes function as effective tools in prosthetic breast reconstruction. Our long-term data suggest that the risk of capsular contracture with these devices is low, and there does not seem to be a difference between the two materials. However, there does need to be a shift in how capsular contracture is assessed and discussed in the reconstruction population.

Shoulder Motion Overestimated by Mallet Scores.

Brachial plexus birth injuries (BPBI) occur in up 0.4 to 4.6 per 1000 live births. Weakness about the shoulder and development of glenohumeral joint contractures are common sequalae of BPBI. Shoulder function in children with BPBI is frequently assessed using the modified Mallet classification to evaluate upper extremity motion deficits. The purpose of this study was to assess the accuracy of the abduction, external rotation, and hand-to-mouth Mallet classification scores in children with BPBI using motion capture. A retrospective study of 107 children with BPBI who underwent motion capture assessment and Mallet scores on the same date were reviewed. Motion capture measurements were used to calculate humerothoracic elevation and external rotation joint angles in the abduction/hand-to-mouth and external rotation positions, respectively. The humerothoracic joint angles were converted to the corresponding Mallet scores. Discrepancies between the Mallet scores determined by clinicians and those determined by motion capture were assessed. For abduction, 24.3% of Mallet scores were misclassified during clinical examination. Of the misclassified scores, 22 were overestimated by 1 point and 4 were underestimated by 1 point compared with motion capture. For external rotation, 72.9% of Mallet scores were misclassified during clinical examination. Only 5 patients had an HT elevation that was less than 40 degrees, with 4 of them (80%) having a Mallet hand-to-mouth score of 4. There were no differences in proportion of patients with HT elevation less than 40 degrees who had a Mallet score of 4 or a Mallet score less than 4. There was better agreement in global abduction Mallet scores compared with external rotation and hand-to-mouth Mallet scores. This difference was likely due to the complex compensatory strategies that patients employ while performing external rotation and hand-to-mouth positions. The inaccuracy of the clinically determined Mallet scores is alarming given that they are frequently utilized to assist with surgical indications and are commonly used as outcome measures. Level IV Case series.

Acellular Dermal Matrix-Assisted, Prosthesis-Based Breast Reconstruction: A Comparison of SurgiMend PRS, AlloDerm, and DermACELL.

Acellular dermal matrices (ADMs) are frequently employed in immediate prosthesis-based breast reconstruction (iPBR) to provide structural support. Despite differences in ADM derivatives, few studies directly compare their outcomes in the setting of iPBR. We sought to conduct a large head-to-head study comparing 3 ADMs used across our institution. A multicenter retrospective review of patients undergoing iPBR with SurgiMend PRS (fetal bovine-derived; Integra Lifesciences, Princeton, NJ), AlloDerm (human-derived; LifeCell Corp, Bridgewater, NJ), or DermACELL (human-derived; Stryker Corp, Kalamazoo, MI) between January 2014 to July 2022 was performed. Primary outcomes included rates of unplanned explantation and total reconstructive failure. Secondary outcomes included 90-day postoperative complications and long-term rates of capsular contracture development. A total of 738 patients (1228 breasts) underwent iPBR during the study period; 405 patients received DermACELL (54.9%), 231 received AlloDerm (31.3%), and 102 received SurgiMend PRS (13.8%). Rates of short-term complications, total reconstruction failure, reoperation within 90 days, capsular contracture, and unplanned explantation were comparable. These findings remained true upon multivariate analysis accounting for baseline differences between cohorts, whereby ADM type was not an independent predictor of any outcome of interest. Conversely, factors such as body mass index, diabetes mellitus, smoking history, neoadjuvant and adjuvant chemotherapy, adjuvant radiation, skin-sparing mastectomy, Wise pattern and periareolar incisions, use of tissue expanders, and a subpectoral plane of insertion were significant predictors of postoperative complications. Low rates of complications support the equivalency of fetal bovine and human-derived ADMs in iPBR. Patient characteristics and operative approach are likely more predictive of postoperative outcomes than ADM derivative alone.

Risk factor analysis and clinical experience of treating capsular contracture after prepectoral implant-based breast reconstruction.

Capsular contracture is one of the most common and severe complications after implant-based breast reconstruction. Recently, prepectoral implant-based breast reconstruction using acellular dermal matrix (ADM) has become an alternative to subpectoral implant-based reconstruction. However, risk factors for capsular contracture associated with recent prepectoral reconstruction trends are not well refined yet. Thus, the aim of this study was to determine risk factors for capsular contracture, and share our experience of treating capsular contracture in prepectoral reconstruction. This retrospective comparative study focused on 110 patients who underwent prepectoral implant-based breast reconstruction with ADM. Risk factors of capsular contracture were analyzed by comparing a capsular contracture group (27 cases) and a non-capsular contracture group (83 cases). Secondary treatment after capsular contracture development was analyzed in capsular contracture group. According to univariate and multivariate analyses of risk factors for capsular contracture, single staged implant-based reconstruction (direct-to-implant), infection, and postoperative radiotherapy were significantly related to the development of capsular contracture. Also, surgical intervention including capsulectomy and capsulotomy with implant change showed a significant higher remission rate than other groups. Our study provides insights into risk factors and treatment choices for capsular contracture after prepectoral implant-based breast reconstruction with ADM. These findings can aid selection of patients, postoperative care and preventative treatment before reconstruction.

Еffect of Radiation Therapy on Breast Reconstruction in Breast Cancer Patients

Background. The surgical stage remains the main one in the combined and complex treatment of breast cancer. Radical mastectomy and reconstructive plastic surgery are the main option for surgical treatment of vast majority patients. Radiation therapy can lead to the development of complications after breast reconstruction, and vice versa, the reconstructed mammary gland can cause technical difficulties for the radiologist to properly adjust the required dose of irradiation. Aim — to choose the optimal method of breast reconstruction using various implants, as well as endoprostheses to minimize post-radiation complications and maintain a high level of quality of life for patients after breast cancer treatment. Methods. The retrospective study was conducted in the department of oncology and reconstructive plastic surgery of the breast and skin in the P.A. Herzen Moscow Research Oncology Institute from June 2013 to November 2017. There were performed 132 operations: 111 subcutaneous mastectomy with one-stage reconstruction with an endoprothesis and 21 mastectomy with a one-stage reconstruction with an endoprothesis. The distribution by stages: I — 57, IIA — 39, IIB — 17, IIIA — 13, IIIC 4; 2 cases of breast sarcoma. Prophylactic mastectomy of the contralateral gland was performed in 22 patients, mastopexy in 8, augmentation in 20. Polyurethane implants were applied in 82 cases (62%). Radiation therapy was performed in 47 patients with total dose 45 Gy. Bilateral reconstruction was performed in 22 patients. Results. The mean follow-up period was 28.44 ± 14.66 months (from 6 to 48 months). The most frequent complication in the postoperative period was the development of capsular contracture: seroma — 20 patients, hematoma — 2, edge necrosis — 6, protrusion — 6, infection — 2 patients. The most common capsular contracture by Baker was III degree, n = 18. The average period of development of capsular contracture was 7.6 ± 11.65 months. Conclusion. Despite the greater number of complications during the one-stage reconstruction, the implants remain in advantage in choosing a method of treating breast cancer by both the patient and the surgeon.

Role of interleukin-17 in juvenile idiopathic arthritis

Joint diseases is a pressing problem of pediatrics. Juvenile idiopathic arthritis is a common chronic systemic inflammatory disease of the joints in children; its etiological factors remain completely unknown. The disease can affect children of any age and is characterized by a long progressive course, leading to the development of contractures and functional failure, and thereby disability. According to the authors of the article, the content of the interleukin-17 in the blood serum of children with juvenile idiopathic arthritis depends on the duration of the disease, as well as its severity.

Immediate Breast Reconstruction With Latissimus Dorsi Myocutaneous Flap and Silicone Implant Followed by Adjuvant Radiotherapy for Breast Cancer.

About 30% to 50% of women with breast cancer undergo mastectomy, and approximately 50% of them will receive adjuvant radiotherapy (ART). This study evaluates the medium- and long-term impact of ART after immediate breast reconstruction (IBR) with latissimus dorsi myocutaneous (LDM) flap and silicone implants. Clinical, surgical, and oncological data were retrospectively collected and analyzed based on the medical records of 176 patients who had undergone IBR with LDM flap and silicone implants. The data showed that 7.4% of patients had a history of previous radiotherapy, 56.3% received ART, 31.8% developed capsular contracture with a mean follow-up of 58.1 months, and 14.2% of surgeries were categorized as procedures with a prolonged operating time, lasting above 1 SD of the observed mean. Those who experienced prolonged operating time (odds ratio, 4.72; 95% confidence interval, 1.72-12.93; P = 0.003) and those who received ART (odds ratio, 7.38; 95% confidence interval, 3.18-17.10; P < 0.001) were more likely to develop capsular contracture. Thirty-two patients (18%) underwent capsulectomy with implant replacement, and 7 patients (4%) had the implant removed. The mean time between IBR and reoperation was 29.1 months. Patients who received ART were 2.84 times more likely to experience reconstruction failure or undergo implant-related reoperation ( P = 0.002). The results indicated that IBR with LDM flap and silicone implant followed by ART is a safe procedure, resulting in low rates of reconstruction failure. However, ART increased the likelihood of capsular contracture development and implant-related reoperation, having a negative effect on reconstructed breasts.

Beyond Contractures in Spinal Muscular Atrophy: Identifying Lower-Limb Joint Hypermobility.

Background: The natural history of spinal muscular atrophy (SMA) is well understood, with progressive muscle weakness resulting in declines in function. The development of contractures is common and negatively impacts function. Clinically, joint hypermobility (JH) is observed but is poorly described, and its relationship with function is unknown. Methods: Lower-limb ROM (range of motion) assessments of extension and flexion at the hip, knee, and ankle were performed. ROMs exceeding the published norms were included in the analysis. The functional assessments performed included the six-minute walk test (6 MWT) and the Hammersmith Functional Motor Scale-Expanded (HFMSE). Results: Of the 143 participants, 86% (n = 123) had at least one ROM measure that was hypermobile, and 22% (n = 32) had three or more. The HFMSE scores were inversely correlated with hip extension JH (r = -0.60, p = 0.21; n = 6) and positively correlated with knee flexion JH (r = 0.24, p = 0.02, n = 89). There was a moderate, inverse relationship between the 6 MWT distance and ankle plantar flexion JH (r = -0.73, p = 0.002; n = 15). Conclusions: JH was identified in nearly all participants in at least one joint in this study. Hip extension, knee flexion and ankle plantar flexion JH was associated with function. A further understanding of the trajectory of lower-limb joint ROM is needed to improve future rehabilitation strategies.

A Comparison of Capsular Contracture Rates after Implant-Based Breast Reconstruction Using ADM Versus Synthetic Mesh

Abstract Goals/Purpose Capsular contracture is a local complication in which there is tightening of the capsule around the implant. This complication has been shown to occur in 15-30% of implant-based breast reconstruction patients and often requires revision surgery for correction. Prior investigations have suggested that the use of ADM can reduce the risk for development of capsular contracture, with more recent research suggesting that synthetic mesh may provide the same benefit. Several meta-analyses have attempted to compare ADM and mesh use for the prevention of capsular contracture, but they all emphasize the continued need for clinical investigation with direct comparisons. The goal of this study is to assess our own reconstruction patient population to compare capsular contracture rates between ADM and mesh cohorts, as well as to assess for other potential risks that may increase the rate of capsular contracture in these patients. Methods/Technique A 15-year retrospective review of all implant-based breast reconstructions performed by the senior author was performed. All operations occurred between 2008 and 2023 in a hospital setting. Patient demographics were assessed including age, BMI, implant size, radiation history, location of malposition, and use of either ADM or mesh. Post-operative complications including incidence of capsular contracture were recorded. Patients who had documented capsular contracture prior to scaffold insertion were excluded from the study. Wilcoxon signed rank test, 2-sided t-test, and Fischer’s Exact test were used to compare baseline demographics and capsular contracture rates between the two groups, along with a multivariate logistic regression analysis to control for potential confounders. Results/Complications Fifty-two breasts underwent capsulorraphy, of which 25 (48.1%) used ADM and 27 (51.9%) used mesh. Average age was 50.6 years, average BMI was 27.7, average implant size was 541.8 cc, and eight breasts (15.4%) had been irradiated. Average follow-up time was seven years (mean = 85.4 months, range 22 – 149 months, SD = 35.9). Fourteen (26.9%) capsulorraphies were for inferior malposition, 13 (25.0%) for lateral malposition, and 25 (48.1%) were for inferolateral malposition. Patients in the ADM group had significantly more lateral malposition prior to insertion as compared to the mesh group which had more inferior malposition (p=0.0246). There was no significant difference between the two groups for any other recorded baseline demographic; these demographics included age, BMI, hypertension, diabetes, history of tobacco use, radiation, chemotherapy, implant volume, and implant surface texture. Capsular contracture occurred in 2 ADM breasts (8.0%) and 4 mesh breasts (14.8%) with no significant difference between the two groups (p=0.6695). Five of these capsular contractures had documented Baker grades with three grade II, one grade III, and one grade IV. None of the recorded baseline demographics significantly increased the risk for capsular contracture development. Conclusion ADM and synthetic mesh both function as effective tools for reducing the risk of developing capsular contracture after prosthetic breast reconstruction. The rate of capsular contracture with ADM was only 8.0% and the rate with mesh was only 14.8%. Both rates are lower than the 15-30% incidence that has been found in breast reconstruction patients without mesh. None of the patient demographics were significant risk factors for capsular contracture development, so these are unlikely to be confounders. There was no significant difference in rate of capsular contracture between the two groups, suggesting that ADM and mesh are similarly efficacious at preventing capsular contracture in reconstruction patients.

The effects of using heel protectors on the prevention of heel pressure injuries and plantar flexion contractures.

Immobilization in the intensive care unit can lead to pressure injuries and plantar flexion contractures. This study was conducted to evaluate the effectiveness of heel protectors applied for the prevention of heel pressure injuries and plantar flexion contractures in intensive care units. This study was conducted as a randomized controlled trial in two adult intensive care units of a teaching and research hospital. The study sample consisted of 84 patients admitted to intensive care units between January 2022 and December 2022. Patients who had been in the intensive care unit for at least 5 days, scored 16 or less on the Braden Pressure Ulcer Risk Assessment Scale and scored 4 or more on the Ramsey Sedation Scale, were included in the study. Heel protector boots were applied to the heels of the patients in the intervention group, while standard positioning with a pillow and ROM exercises were continued in the control group. A sociodemographic data form, the Ramsey Sedation Scale and the Braden Pressure Ulcer Risk Assessment Scale were used to collect data. While pressure injuries were evaluated with the International NPUAP-EPUAP Pressure Ulcer Classification System, goniometric measurements were made to evaluate joint ROM. In the intervention group, heel pressure injuries did not develop during the study, whereas five patients in the control group developed heel pressure injuries. The risk of pressure injury development that was seen in the control group was 1.7 times higher compared with the risk for the intervention group (log 95% CI: 0.91-2.59). There were significant differences between the right foot (99%; F = 99.229; p = .000) and left foot (99%; F = 100.519; p = .000) in range of motion measurement values of the patients in the intervention group according to the measurement times. According to the results of the multiple comparison test (Bonferroni) performed to determine the range of motion measurement periods showing significant differences, it was observed that each measurement for both feet yielded lower results than the previous measurement (seven measurements from day 1 to day 13). The use of heel protector boots was found to be effective in preventing the development of heel pressure injuries and plantar flexion contractures in intensive care unit patients. This study provides evidence that intensive care nurses can use heel protector boots to prevent the development of heel pressure injuries and plantar flexion contractures.

Congenital Dislocation of the Knee in the Delivery Room.

BACKGROUND Congenital dislocation of the knee (CDK) is rare and can cause significant distress in the delivery room to parents and to healthcare providers, especially if the latter are unaware of this condition. It may not be detected by prenatal ultrasound and can be either an isolated finding or associated with other anomalies such as developmental hip dysplasia and genetic syndromes such as Larsen syndrome. Because of the risk of development of contractures, immediate referral to a specialized provider is needed. Poor prognostic factors include an association with a genetic syndrome, limited knee flexion related to severe quadriceps retraction, and absence of anterior skin grooves. A satisfactory outcome can be anticipated in isolated cases with easy reducibility of the knee. CASE REPORT A term baby presented unexpectedly with left knee dislocation after delivery. The providers, unaware of the condition, immediately consulted the orthopedic service, who assisted in the diagnosis, and appropriate management was initiated. The baby had serial casting of the leg, which was applied for almost 3 months, with excellent results on the clinical examination. CONCLUSIONS CDK is a rare finding. The diagnosis is primarily clinical and radiographs are used to confirm and assess the degree of the dislocation. The degree of dislocation is important for management and prognosis. Interventions ranging from serial casting to surgery are required as soon as possible. As the CDK can be associated with genetic syndromes or other dysplasias such as developmental dysplasia of the hip and talipes equinovarus, further evaluation for these conditions is warranted.

Frequency of pulley lesions in patients with frozen shoulder

Background. Analyzing the results of studies conduc­ted at various MRI centers in different cities of our country, demonstrates that the diagnosis of pulley lesion was only established in a few of them, while the diagnosis of adhesive capsulitis was established in every third examination. This fact leads to the disregard of the primary cause of the disease, diagnostic errors, and consequently, treatment mistakes. The purpose was to investigate the frequency of different types of pulley lesions involving the ligaments that maintain the integrity of the long head of the biceps (pulley lesion injuries) in patients with adhesive capsulitis of the shoulder joint (frozen shoulder). Materials and methods. We performed 310 ope­rations on patients with adhesive capsulitis of the shoulder. The patients’ ages ranged from 30 to 90 years. The average duration from the onset of the disease to surgical intervention was 189 ± 104 days. All patients were examined clinically and radiologically and all patients underwent MRI study of anatomical structures and shoulder joint arthroscopy. Results. Pulley lesion injuries of the shoulder joint were detected in 84 (27.1 %) of the patients who underwent surgery for a frozen shoulder. This allows us to assert that in this particular patient group, secondary adhesive capsulitis with the development of shoulder joint contracture was predominant. The third (16.5 %) and fourth (12.4 %) types of pulley lesion injuries were the most prevalent. These particular types of pulley lesion injuries exhibit the most contracture-inducing properties, with the third type predominating over the fourth type. А change in the type of pulley lesion damage (an increase in the number of damaged structures of the shoulder), the average indicators of the mobility of the shoulder decreased. Conclusions. In 27.1% of patients who were opera­ted on for idiopathic adhesive capsulitis was detected pulley lesion, which gives us to reconsider treatment approaches and expand the indications for diagnostic and therapeutic shoulder arthroscopy in the earlier stages of the disease.
