Preoperative chronic steroid use as a risk factor for complications following open reduction internal fixation for proximal humerus fracture.

The primary objective of this study was to investigate the association between preoperative chronic steroid use and postoperative complications following open reduction internal fixation(ORIF) for proximal humerus fractures(PHF). The American College of Surgeons National Surgical Quality Improvement (ACS-NSQIP) database was queried for all patients who underwent PHF ORIF between 2015 and 2021. A total of 6,273 patients were included in this study, of which 3.4% (n = 212) were in the chronic steroid use cohort. Patient characteristics including demographics, comorbidities, and 30-day postoperative complications after PHF ORIF were collected. Bivariate logistic regression and multivariate logistic regression analysis, adjusted for all significantly associated variables, was conducted to investigate the relationship between preoperative chronic steroid use and postoperative complications. Chronic steroid use was significantly associated with age ≥ 75 (p < 0.001), male gender (p =0.006), dependent functional status (p = 0.008), American Society of Anesthesiologist (ASA) ≥ 3 (p < 0.001), CHF (p = 0.007), hypertension (p < 0.001), COPD (p < 0.001), bleeding disorder (p = 0.007), ascites (p = 0.040), disseminated cancer (p< 0.001), and systemic sepsis (p < 0.001). After adjusting for all significantly associated variables, chronic steroid use was independently associated with major complication (OR 1.60, 95% CI 1.06-2.43; p = 0.026), and non-home discharge (OR 1.05, 95% CI 1.01-1.08; p = 0.014). Preoperative chronic steroid use is associated with increasing rate of postoperative complications following PHF ORIF. Better understanding and characterizing chronic steroid use as a preoperative risk factor can aid physicians in risk stratification to reduce rates of postoperative complications following PHF ORIF.

Outcomes of surgical management of ankle fractures in patients with diabetes

ObjectiveAnkle fracture surgeries among diabetic are common and can have fatal consequences and serious adverse outcomes. A target hemoglobin A1c (HbA1c) level <8% in all elective surgeries for patients with diabetes is suggested to minimize poor outcomes. We investigated the postoperative outcomes and complications among patients who underwent ankle fracture surgery using HbA1c level as a predictor value. MethodsThis retrospective cohort study was conducted at King Abdulaziz Medical City between January 2016 and December 2022 on all patients with diabetes who underwent open reduction and internal fixation and who had a documented HbA1c level. Radiological outcomes and complications were noted along with the levels of HbA1c and analyzed statistically. ResultsA total of 44 patients were included in the study: 29 women (65.9%) and 15 (34.1%) men. The most frequent ankle fracture type was bimalleolar (54.5%). HbA1c was elevated (54.5%) in patients. A significantly higher proportion of patients who had <8% HbA1c level had radiological union compared to patients who had ≥8% HbA1c level (p = 0.036). Patients who had elevated HbA1c level had more complications although it did not reach statistical significance (p > 0.05). Multivariate regression analysis showed that age and HbA1c level were the significant factors for an uncomplicated and successful ankle surgery. ConclusionPoor postoperative outcomes and complications are more common among patients with elevated HbA1c. This suggests that an elevated HbA1c level is associated with a poor treatment outcome. Determination of HbA1c levels may predict potential problems post ankle fracture surgery and improve management outcomes.

Risk factors and incidence of short-term complications following open reduction and internal fixation of scapula fractures.

To determine the short-term complication rates following open reduction and internal fixation of scapula fractures, factors affecting the development of adverse events, and complication rates based on the anatomic location of the fracture. Thirty-day complication rates for patients who underwent open reduction and internal fixation of the scapula were compared between glenoid, body, coracoid, and acromion fracture locations, as identified by International Classification of Disease codes. Possible adverse events included postoperative surgical site infection, renal insufficiency, intubation, pneumonia, deep vein thrombosis, pulmonary embolism, urinary tract infection, wound dehiscence, stroke, and blood transfusion. A total of 251 scapula fractures were identified, with 161 having known fracture locations: 105 glenoid, 20 body, 9 coracoid, and 27 acromial fractures. The rate of any adverse event for all scapular fractures was 2.0%, with no significant difference between anatomic locations (p = 0.79). The overall rates of transfusion, surgical site infection, and return to OR were 0.4%, 0.8%, and 3.98%. Steroid use associated with a significantly increased risk of any adverse event (OR: 55.57, p = 0.038) and outpatient status demonstrated a protective effect on reoperation (OR: 0.11, p = 0.014). There were no significant differences in the rates between groups [transfusion (p = 0.91); surgical site infection (p = 0.17); reoperation (p = 0.85)]. Complication rates within thirty days of ORIF for scapula fracture were low. Reoperation was the most common complication, followed by surgical site infection, wound dehiscence, stroke, transfusion, and pneumonia. Steroid use was a risk factor for developing any adverse event, and outpatient status was protective against reoperation. The 30-day complication profile of glenoid, body, coracoid, and acromial fractures was not significantly different. The low complication rates support the relative short-term safety of operative intervention with internal fixation. Level III.

Enhanced Degradability of Thiol-Ene Composites through the Inclusion of Isosorbide-Based Polycarbonates.

Open reduction internal fixation metal plates and screws remain the established standard-of-care for complex fracture fixation. They, however, have drawbacks such as limited customization, soft-tissue adhesions, and a lack of degradation. Bone cements and composites are being developed as alternative fixation techniques in order to overcome these issues. One such composite is a strong, stiff, and shapeable hydroxyapatite-containing material consisting of 1,3,5-triazine-2,4,6-trione (TATO) monomers, which cures through high energy visible light-induced thiol-ene coupling (TEC) chemistry. Previous human cadaver and in vivo studies have shown that patches of this composite provide sufficient fixation for healing bone fractures; however, the composite lacks degradability. To promote degradation through hydrolysis, new allyl-functionalized isosorbide-based polycarbonates have been added into the composite formulation, and their impact has been evaluated. Three polycarbonates with allyl functionalities, located at the termini (aPC1 and aPC2) or in the backbone (aPC3), were synthesized. Composites containing 1, 3, and 5 wt % of aPCs 1-3 were formulated and evaluated with regard to mechanical properties, water absorption, hydrolytic degradation, and cytotoxicity. Allyl-functionalized polycaprolactone (aPCL) was synthesized and used as a comparison. When integrated into the composite, aPC3 significantly impacted the material's properties, with the 5 wt % aPC3 formulation showing a significant increase in degradation of 469%, relative to the formulation not containing any aPCs after 8 weeks' immersion in PBS, along with a modest decrease in modulus of 28% to 4.01 (0.3) GPa. Osteosyntheses combining the aPC3 3 and 5 wt % formulations with screws on synthetic bones with ostectomies matched or outperformed the ones made with the previously studied neat composite with regard to bending stiffness and strength in four-point monotonic bending before and after immersion in PBS. The favorable mechanical properties, increased degradation, and nontoxic characteristics of the materials present aPC3 as a promising additive for the TATO composite formulations. This combination resulted in stiff composites with long-term degradation that are suitable for bone fracture repair.

Prevalence and Risk Factors for Stiffness Following Open Reduction for Developmental Dysplasia of the Hip.

Most prior investigations on adverse outcomes after open reduction (OR) for developmental dysplasia of the hip (DDH) have focused on avascular necrosis, redislocation, and residual dysplasia. To our knowledge, no previous study has investigated risk factors for stiffness, an underappreciated source of postoperative morbidity. The goals of this study were to define the entity more clearly and evaluate the prevalence and risk factors for arthrofibrosis after OR for DDH. A retrospective study was conducted, including all open hip reductions for DDH performed by a single surgeon from 2009 to 2022. Preoperative anteroposterior pelvic radiographs were used to calculate superior displacement, which was defined as the distance from the highest point of the proximal femoral metaphysis to the Hilgenreiner line, normalized by pelvic width. Cases treated with premature postoperative bracing cessation and/or referral to physical therapy with a resolution of stiffness within 6 months were categorized as mild arthrofibrosis. Cases that required >6 months of formal physical therapy for persistent range of motion concerns, manipulation under anesthesia, and/or inpatient rehabilitation admission were categorized as significant arthrofibrosis. This study included 170 hips with a mean age of 21.6 months (range: 6.1 to 93.6mo) and a mean follow-up of 46.8 months. 156 ORs (91.8%) were done through an anterior approach. Sixty-four patients (37.6%) had a concomitant isolated pelvic osteotomy, and 34 (20.0%) had both pelvic and femoral osteotomies. During the postoperative course, 109 patients (64.1%) had no arthrofibrosis, 38 (22.4%) had mild stiffness, and 23 (13.5%) had significant arthrofibrosis. On multivariable analysis, older age, superior displacement, and concomitant pelvic osteotomy were associated with any degree of arthrofibrosis (P< 0.05). Children older than 18 months or with dislocations higher than 16% of pelvic width had a 4.7 and 2.7 times higher risk, respectively, of experiencing some degree of stiffness postoperatively. Older age, high dislocations, and concomitant pelvic osteotomy without femoral shortening are risk factors for stiffness after OR for DDH. Surgeons should counsel families about the risk of postoperative stiffness, which occurred to some degree in 36% of our patients. Level IV.

Closed Reduction Techniques Are Associated With Fewer Complications Than Open Reductions in Treating Moderately Displaced Pediatric Lateral Humeral Condyle Fractures: A Multicenter Study.

Lateral humeral condyle (LC) fractures are the second most common pediatric elbow fractures. Traditionally, displaced fractures have been treated with open reduction although recent studies have demonstrated successful outcomes of closed reduction for similar injuries. This study investigates the outcomes comparing open and closed reduction in a large cohort of children with moderately displaced (Song classification types 1 to 4) lateral humeral condyle fractures. Retrospective data from patients aged between 1 and 12 years treated for lateral condyle fractures was collected from 6 academic level 1 trauma centers between 2005 and 2019. Data was collected on patient demographics, radiographic parameters, reduction type, type of hardware fixation, and fracture patterns. Complications recorded include infections, reoperations for nonunion, osteonecrosis, and elbow stiffness. An initial 762 fractures were identified. After excluding Song 5 cases, a total of 480 fractures met inclusion criteria, with 202 (42%) treated with closed reduction and 278 (58%) treated with open reduction. Demographics and injury characteristics were similar across the 2 reduction cohorts. After propensity score matching, delayed healing (52% vs. 28%; OR: 2.88, 95% CI: 1.97-4.22; P<0.0001) and stiffness (22% vs. 10%; OR 2.42, 95% CI: 1.42-4.13; P=0.0012) were significantly higher in the open reduction group. No differences in the rates of infection or nonunion (3% CR and 1% OR) were noted between the 2 groups. This study demonstrates that moderately displaced lateral condyle fractures requiring open reduction are more likely to have elbow stiffness and delayed healing when compared with the ones treated with closed reduction. For these reasons, we propose attempting closed reduction techniques as the first line of treatment in moderately displaced lateral humeral condyle fractures (if anatomic articular reduction can be achieved) to attain better patient outcomes.

Comparative outcomes of uncemented and cemented stem revision in managing periprosthetic femoral fractures: a retrospective cohort study

IntroductionPeriprosthetic femoral fractures (PFFs) following hip arthroplasty, especially Vancouver B2 and B3 fractures, present a challenge due to the association with a loose femoral stem, necessitating either open reduction and internal fixation or stem revision. This study aims to compare outcomes between uncemented and cemented stem revisions in managing Vancouver B2 and B3 fractures, considering factors such as hip-related complications, reoperations, and clinical outcome.MethodsA retrospective cohort study was conducted at Danderyd Hospital, Sweden, from 2008 to 2022, encompassing operatively treated Vancouver B2 and B3 fractures. Patients were categorized into uncemented and cemented stem revision groups, with data collected on complications, revision surgeries, fracture healing times, and clinical outcomes.ResultsA total of 241 patients were identified. Significant differences were observed between the two groups in patient demographics, with the cemented group comprising older patients and more females. Follow up ranged from 1 to 15 years. Average follow up time was 3.9 years for the cemented group and 5.5 years for the uncemented group. The cemented stems demonstrated lower rates of dislocation (8.9% versus 22.5%, P = 0.004) and stem loosening (0.6% versus 9.3%, P = 0.004) than the uncemented method. Moreover, the cemented group exhibited shorter fracture healing times (11.4 weeks versus 16.7 weeks, P = 0.034). There was no difference in clinical outcome between groups. Mortality was higher in the cemented group.ConclusionsThis retrospective study indicates that cemented stem revision for Vancouver B2–3 fractures is correlated with lower dislocation and stem loosening rates, necessitating fewer reoperations and shorter fracture healing times compared with the uncemented approach. The cemented group had a notably higher mortality rate, urging caution in its clinical interpretation.Level of evidence III

A trans-eyebrow zig-zag approach for frontal bone fractures

Frontal bone fractures are amongst the most common facial fractures and surgical management, which has traditionally involved access via a coronal flap, can result in unsightly scarring, alopecia, paraesthesia, facial nerve weakness and temporal hollowing. Alternative approaches include use of endoscopically-assisted surgery, often through the eyebrow, which minimises the risk of unsightly scarring but may also sacrifice access in the process. In this technical note, we discuss a surgical technique for open reduction and internal fixation of fractures of the bone overlying the frontal sinus and supra-orbital rim, which the authors have not found in the literature, which involves the making of a “zig-zag” incision through the eyebrow in a trichophytic manner which reduces the risk of unsightly scarring whilst simultaneously allowing for sufficient surgical access to the fracture site.

Treatment of posterolateral tibial plateau fractures: a narrative review and therapeutic strategy.

The posterolateral tibial plateau is crucial for maintaining knee stability during flexion, and fractures in this area often involve ligament and meniscus injuries, necessitating effective management. However, treating posterolateral tibial plateau fractures (PLF) poses significant challenges due to the complex anatomy. Therefore, this review aims to explore contemporary concepts of PLF, from identification to fixation, and proposes a comprehensive treatment strategy. In this article, the authors detail the injury mechanisms, fracture morphology, PLF classification systems, surgical approaches, and techniques for open reduction and internal fixation (ORIF) as well as arthroscopic-assisted internal fixation (ARIF). The findings indicate that PLF is typically caused by flexion-valgus forces, resulting in depression or split-depression patterns. For isolated PLF, the supra-fibular head approach is often preferable, whereas posterior approaches are more suitable for combined fractures. Additionally, innovative plates, particularly the horizontal belt plate, have shown satisfactory outcomes in treating PLF. Currently, the 'bicondylar four-quadrant' concept is widely used for assessing and managing the tibial plateau fractures involving PLF, forming the cornerstone of the comprehensive treatment strategy. Despite challenges in surgical exposure and implant placement, ORIF remains the mainstream treatment for PLF, benefiting significantly from the supra-fibular head approach and the horizontal belt plate. Furthermore, ARIF has proven effective by providing enhanced visualization and surgical precision in managing PLF, emerging as a promising technique.

Application of reverse traction device in preoperative treatment of high-energy tibial plateau fracture

To investigate the effectiveness of the reverse traction device in the preoperative treatment of high-energy tibial plateau fractures. A retrospective study was conducted to analyze the clinical data of 33 patients with high-energy tibial plateau fractures who met the selection criteria between December 2020 and December 2023. All patients were treated by open reduction and internal fixation. According to the preoperative traction method, they were divided into the observation group (16 cases, treated with a reverse traction device on the day of admission) and the control group (17 cases, treated with heel traction on the day of admission). There was no significant difference in baseline data such as gender, age, body mass index, affected side, cause of injury, fracture Schatzker classification between the two groups ( P>0.05). Preoperative waiting time, preoperative related complications (nail channel loosening, nail channel oozing, nail channel infection, soft tissue necrosis, soft tissue infection, deep vein thrombosis of the lower extremity, etc.), operation time, and total hospitalization time were recorded and compared between the two groups. On the 4th day after traction, visual analogue scale (VAS) score was used to evaluate the pain relief of the patients, the swelling value of the affected limb was measured, and the Immobilization Comfort Questionnaire (ICQ) score was used to evaluate the perioperative hospital comfort of the patients. Both groups of patients completed the operation successfully, and the operation time, total hospitalization time, and preoperative waiting time of the observation group were significantly less than those of the control group ( P<0.05). There was no preoperative related complications in the observation group; in the control group, 3 patients had nail channel loosening and oozing, and 2 cases had the deep vein thrombosis of the lower extremity; the difference in the incidence of complication between the two groups was significant ( P<0.05). On the 4th day after traction, the ICQ score, VAS score, and limb swelling value of the observation group were significantly better than those of the control group ( P<0.05). X-ray films showed that the tibial plateau fracture separation and lower limb alignment recovered after calcaneal traction in the control group, but not as obvious as in the observation group. The fracture gap in the observation group significantly reduced, the tibial plateau alignment was good, and the lateral angulation deformity was corrected. The use of reverse traction treatment in patients with high-energy tibial plateau fractures on admission can accelerate the swelling around the soft tissues to subside, reduce patients' pain, shorten the preoperative waiting time, improve the patients' preoperative quality of life, and contribute to the shortening of the operation time, with a good effectiveness.

A comparative study of functional outcome of percutaneous kirschner wire fixation versus philos plating of proximal humerus fractures

: Proximal humerus fractures, accounting for approximately 5% of all fractures, pose a significant challenge in orthopedic management due to their complex anatomy and diverse fracture patterns. Treatment options range from conservative methods to various surgical interventions, each with its pros and cons. This study specifically compares two commonly employed surgical techniques: Open reduction &amp; internal fixation with PHILOS plate and percutaneous k-wire fixation with/without external clamps. This study aims to address the effectiveness of each technique by evaluating functional outcomes using validated scoring systems like the Constant-Murley Score. To assess the functional outcomes of two surgical treatment methods (K-wire application and PHILOS plate fixation) for proximal humerus fractures. : A randomized prospective study was conducted on patients coming to the Orthopaedics outpatient department or casualty of tertiary care hospital for a duration of 1 year from Dec 2022 to Nov 2023. A total of 18 patients were included in the study. The mean Constant- Murley Score (CMS) was 81 +/- 6.13 for the PHILOS plating group and 76.88 +/- 7.37 for the K-wire treated group with a p-value of 0.08. The results for CMS were excellent in 22.2% of patients and good in 66.7% of patients in PHILOS treated group and excellent for 11.11%, good for 66.67% and satisfactory for 22.2% in the K-wire treated group. Both groups achieved satisfactory functional outcomes with CM Score at the final follow-up. Both techniques achieved favorable outcomes, with a majority of patients in both groups (88.89% for PHILOS and 77.78% for K-wire) achieving good to excellent results based on the CMS scores.

Pediatric-Specific Lesions in Unstable Pelvic Ring Fractures of Skeletally Immature Children: Impact on Diagnosis and Management Decisions.

Surgical fixation of pediatric pelvic ring injuries is gaining popularity to avoid the poor long-term outcomes of pelvic asymmetry. The surgical techniques and fixation choices depend on the individual injuries affecting the anterior and posterior pelvic ring areas. The immature bony pelvis of young children has anatomic differences including soft bones, elastic ligaments, and the presence of growth centers. Understanding the unique pediatric lesions with unstable pelvic fractures is essential for treatment decisions. Anterior lesions include pubic symphysis disruption through the pubic apophysis, single ramus fractures, pubic rami fractures through the triradiate cartilage, and/or the ischiopubic synchondrosis; ischiopubic ramus infolding injury; or the unstable superior and inferior quadrant lesions. Posterior pelvic lesions include iliac wing infolding and sacroiliac joint dislocation or transiliac (crescent) fracture/dislocations through the iliac apophysis growth plate. Pubic symphysis and sacroiliac disruptions are physeal injuries in children, and they have excellent healing potential. External fixation is an ideal choice for anterior ring fixation including bony and pubic symphysis injuries. Posterior lesions are mostly sacroiliac joint disruptions with iliac apophysis separation that can serve as a landmark for vertical displacement correction. Posterior lesions can be treated by percutaneous iliosacral screw fixation or open reduction techniques.

Local residents’ willingness to allow deer herd reduction and other CWD operations on their property

ABSTRACT Herd reduction or reducing the population density of deer in infested areas is a widely considered method to combat CWD. However, the viability of this method relies on interest and cooperation from local residents that may have different values, attitudes towards such methods. This paper summarizes key findings from a recent survey of local residents in CWD infested area in West Tennessee to explain the barriers and opportunities in securing local cooperation for this method of CWD management. State wildlife agencies and their conservation partners will benefit from these findings in designing appropriate communication, outreach and incentive mechanism towards a successful CWD management.

Perilunate Fracture-Dislocation: Results at Mean Follow-Up of 7 Years after ORIF.

Background: Perilunate fracture-dislocations are frequently associated with a high risk of developing post-traumatic arthritis. Current studies indicate that during mid-term follow-ups, radiological signs of arthritis do not appear to correspond with functional score. The aim of this study was to assess the occurrence of posttraumatic arthritis and the wrist function after perilunate dislocations (PLD) and fracture dislocations at a mid-term follow-up of 7 years. Methods: We report the clinical and radiological outcomes of 17 wrists treated for PLD or fracture-dislocation by open reduction and internal fixation through a dorsal approach with dorsal ligament repair. Functional outcomes were evaluated using the short version of the Quick Disabilities of the Arm, Shoulder and Hand questionnaire (QuickDASH), the Patient-Rated Wrist Evaluation questionnaire (PRWE) and the Mayo Wrist Score (MWS). Results of radiographs were assessed using the Herzberg Radiological Scoring Chart. Results: The MWS showed five excellent, five good, five fair and two poor results with an average score of 81%. Radiological analysis using the Herzberg classification revealed midcarpal and/or radiocarpal arthritis in 65% of cases, lunate collapse in 59% and an increase in the mean ulnar translocation ratio in 53% of the cases. Complications included one case of lunate osteonecrosis and one case of stage 3 scapholunate advanced collapse that required revision surgery. Conclusions: Although the clinical and functional outcomes are favourable at mid-term follow-up, radiological evaluation shows a progression towards osteoarthritis (OA). Further research is warranted to refine treatment strategies and investigate factors influencing the development of OA. Level of Evidence: Level IV (Therapeutic).

Primary Reconstruction Using Fibular Strut Allograft for Distal Humerus Intra-articular Comminuted Open Fracture (AO/OTA13C2, G-A type IIIA): A Case Report.

Distal humerus intra-articular comminuted open fracture is a challenging injury, with nonunion, infection and stiffness considered as major concerns. We report a 58-year-old woman who was admitted to the emergency department from a car accident, sustaining an open wound with severe comminution of distal humerus and complete articular fracture, classified as AO/OTA 13C2 and Gustillo Anderson type IIIA. Debridement and external fixation was done first, followed by open reduction and internal fixation with fibular strut allograft. The patient showed excellent results in radiological and functional outcomes. Level of Evidence: Level V (Therapeutic).

Posterolateral Locked Plate and Percutaneous Medial Screw Fixation for Distal Humerus Fractures in Elderly.

Background: A high incidence of ulnar nerve-related complications has been reported in open reduction and internal fixation for distal humerus fractures (DHFs). To minimise ulnar nerve damage, we used a percutaneous medial screw combined with a posterolateral plate in the elderly. The aim of this study was to evaluate the postoperative complications and functional outcomes of this method. Methods: Data from patients aged over 65 who underwent this surgical procedure for DHFs at a single Level I trauma centre from 2013 to 2021 were extracted. Postoperative complications, reoperations, mean range of motion, Mayo Elbow Performance Index (MEPI) scores and Hand20 scores were retrospectively evaluated. All patients in this study received postoperative rehabilitation by hand therapists at our hospital. Results: We identified 28 patients treated with this method. The mean follow-up period was 8.6 ± 3.7 months. The median intraoperative time was 125 minutes (interquartile range: 105-157 minutes). None of the patients developed ulnar nerve neuropathy, but one patient (3.7%) experienced radial nerve dysfunction. Two patients (7.4%) had nonunion. Implant failure occurred in three patients (11.1%) due to migration of the medial screw. One patient (3.7%) amongst them underwent reoperation. The mean flexion to extension arc was 97 ± 18°, 116 ± 19°, and 116 ± 19° at 1-, 3- and 6-month follow-ups, respectively. According to the MEPI, 20 patients achieved excellent results, seven patients achieved good results and one patient achieved a fair result at the last follow-up. The median Hand20 score was 4.3 (interquartile range: 2.1-14.0) at the 6-month follow-up. Conclusions: The posterolateral plate and medial screw method showed good functional outcomes and few nerve-related complications. This modified method might be a better option for DHFs in elderly patients. Level of Evidence: Level IV (Therapeutic).

Pins and Rubber Band Traction System Combined with Internal Fixation for Intra-articular Fractures of the Proximal Interphalangeal Joints.

Background: Intra-articular fractures of the proximal interphalangeal joint (PIPJ) can result in poor outcomes if inadequately treated. Dynamic external fixation and internal fixation with plates and/or screws are two treatment options. The role of combining these two methods is unclear. The aim of this study is to determine the outcomes of patients with intra-articular fractures of the PIPJ treated with a combination of dynamic external fixation with a plate and/or screws. Methods: A retrospective review was conducted on 18 consecutive cases of intra-articular fractures of the PIPJ treated with pins and rubber band traction system (PRTS) combined with dorsal internal fixation with plates and/or screws. The patients' average age was 51 years (range: 20-81 years). The fracture patterns were volar-type (n=2), dorsal-type (n=4) and pilon-type (n=12). Data with regard to time to surgery, interphalangeal joint range of motion, grip strength, VAS for pain, Quick DASH score, complications, duration of follow-up and return to work were collected. Results: The levels of articular involvement were stable (n=1), tenuous (n=5) and unstable (n=12). The average time to surgery was 9 days, and the average follow-up period was 15 months. The fracture was fixed with a dorsal plate and screws in 10 patients and with only screws in eight patients. All patients had PRTS. All patients returned to their original occupation and the fractures united in good alignment. The average grip strength was 86% of that of the unaffected side. The average active PIPJ motion was 85° (range: 50°-106°), and the average active distal interphalangeal joint (DIPJ) motion was 48° (range: 10°-90°). Conclusions: Our results show that a combination of PRTS and open reduction and fixation with plate and/or screws achieved a good range of motion and articular reduction. Level of Evidence: Level IV (Therapeutic).

A Systematic Review and Network Meta-Analysis of Randomised Controlled Trials Comparing Treatments for Displaced Radial Head Fractures.

Background: The aim of this study is to compare the surgical and non-operative management of displaced radial head fractures via a network meta-analysis of randomised controlled trials (RCTs). Methods: RCTs comparing management of isolated, displaced radial head fractures in adults were included in our review and statistical analysis. A systematic review of electronic databases (Medline, Embase and Cochrane Library) were screened for comparative RCTs reporting on the management of displaced radial head fractures in August 2021. Two investigators independently reviewed studies for eligibility and an assessment of bias was performed for each study. A Bayesian network meta-analysis of the included RCTs was performed. Results: Five RCTs (326 patients) were included in our meta-analysis. Treatment methods included radial head arthroplasty (RHA), open reduction internal fixation (ORIF) with metal implants (ORIF-M), ORIF with biodegradable implants (ORIF-B) and non-operative management. In our network meta-analysis of 'good' or 'excellent' patient-reported outcome measures (PROMs), RHA was significantly favourable to ORIF-M (OR: 0.04, CrI: 0.0011, 0.87), ORIF-B (OR: 0.1 CrI: 0.00076, 6.37). Nonoperative treatment was not shown to be significantly worse than RHA (OR: 0.01 CrI: 2.5e-0.5, 3.61). Conclusions: This network meta-analysis shows that in displaced radial head fractures, RHA is associated with significantly superior functional PROMs than ORIF-M based on the evidence available. Nonoperative management has not been shown to be significantly worse. Level of Evidence: Level III (Therapeutic).

The Application of Lag Screws and Digital Positioning Guide in Treating Sagittal Split Fracture of the Mandible.

Sagittal mandibular fractures are challenging to manage using traditional open reduction and internal fixation techniques due to the difficulty in manually reducing mandibular fragments and performing osteosynthesis on the lingual side. In addition, there is a risk of damaging dental roots with screws during fixation. In this case, the authors employed the lag screw technique combined with digitally guided surgery to effectively perform osteosynthesis on the fragments and avoid iatrogenic tooth and nerve injury.
