Objective: The lateral patellofemoral ligament (LPFL) is part of the lateral retinaculum cut during arthroscopic or open release. We investigated its anatomic and morphometric characteristics. Materials and methods: We identified the LPFL insertion point on the condyle in vertical and sagittal planes in 32 adult cadaveric knees. We measured its length and width at the insertion point. We located the midpoint of this point and measured from it to the distal and posterior condylar ends. We measured anterior-posterior and proximal-distal lateral condylar lengths. We evaluated the insertion point shape on the lateral femoral condyle. Degree of relationship between variables was assessed using Pearson's correlation coefficient. p < 0.05 was considered statistically significant. Results: The LPFL mean length was 23.2 mm, and mean width at the insertion point was 15.6 mm. Regarding its insertion into the lateral condyle, central insertions were more frequent (vertical plane: 53.1% central and sagittal plane: 75% central). A significant positive correlation was evident between the LPFL length and width at the insertion point (p ¼ 0.05). Thus, the LPFL length was proportional to its width at the insertion point. A significant positive correlation was found between the anterior-posterior condylar length and width of the LPFL at the insertion point (p ¼ 0.017). Therefore, greater anteriorposterior condylar length equates to a larger area of insertion on the condyle. Conclusion: Greater width of the LPFL at the insertion point corresponds to greater LPFL and anteriorposterior lateral condylar lengths.

Extension-block pinning is a popular treatment for mallet fractures, but it is associated with several pitfalls. Of note, transfixation Kirschner wires used to fix the distal interphalangeal (DIP) joint may cause iatrogenic nail bed injury, bone fragment rotation, chondral damage, or osteoarthritis. The objective of this study was to determine whether a transfixation pin was necessary for extension-block pinning in the treatment of bony mallet fracture. Patients were treated with a pin-orthosis extension-block technique if they had been diagnosed with a type IVB mallet fracture according to Doyle's classification. Radiological outcomes were evaluated based on postoperative X-ray results, and functional outcomes were evaluated using Crawford's criteria. Thirteen patients (9 males and 4 females) with a mean age of 26 years were included. The mean time between the injury and surgery was 3.3 days, and the mean follow-up period was 8.2 months (range: 4-12 months). Radiographic bone union was achieved in all patients within an average of 5.1 weeks (range: 5-6 weeks). At the final follow-up, the DIP joint had an average degree of flexion of 76.1° (range: 65°-80°) and an average extension deficit of 3.84° (range: 0°-15°). According to Crawford's criteria, 8 patients had excellent results, 4 patients had good results, and 1 patient had a fair result. No patient reported pain at the final follow-up. Satisfactory clinical and radiological outcomes were obtained with the pin-orthosis extension-block technique. Future prospective and randomized studies are justified to confirm the efficacy of this technique.

Objective: The present retrospective study evaluated the clinical and radiologic results of patients who underwent complete curettage and autologous bone grafting for hand-located isolated enchondromas with a minimum follow-up period of one year. Patients and Methods: Thirty-two patients with a follow-up period of at least 12 months who underwent operation between August 2010 and October 2018 due to the presence of solitary enchondroma of the hand were included in the study. All patients underwent complete curettage and filling of the defect via autologous bone grafting. Autologous bone graft was harvested from the iliac crest and distal radius in 24 and eight patients, respectively. The patients underwent radiography on the first postoperative visit and at six weeks, 12 weeks, and annually. The range of movement of the finger joint was evaluated by comparing it with the healthy contralateral side. Functional outcomes and radiologic outcomes were evaluated. The frequency of complications and recurrences were established. Results: Twelve patients were male and 20 were female. The average age was 34 (range: 16-56) years. The most common digit involved was the little finger (nine cases, 28.125%); the proximal phalanx was the most common location (17 cases, 53.125%). Control radiography in the sixth week revealed graft consolidation in all patients. No case of nonunion or recurrence was detected clinically or radiologically, with a mean follow-up period of 54 (range: 12-96) months. Functional outcomes were classified as excellent in 28 patients and as good in four patients. The final radiographic appearances included Tordai’s group 1 in 28 bones and group 2 in four bones. Conclusion: Curettage and autologous bone grafting are safe, costless, and effective treatment options for hand enchondroma, with satisfactory functional and radiographic outcomes. Harvesting bone graft from the distal radius provides a shorter length of hospital stay and lower complication rates compared to obtaining the graft from the iliac crest.

Background: Rotator cuff tears commonly cause shoulder pain and functional impairment, prompting surgical intervention such as mini-open and arthroscopic methods, each with distinct benefits. This study aimed to compare the clinical outcomes and complications of these two approaches. Methods: A retrospective analysis was conducted on 165 patients who underwent rotator cuff repair using either arthroscopic-assisted mini-open or full arthroscopic approaches. Patient demographics, tear characteristics, clinical outcomes, and complications were assessed, with statistical analyses conducted to discern differences between the groups.Results: Among the patients, 74 (53.2%) received the mini-open approach, while 65 (46.8%) underwent arthroscopic repair, with a mean follow-up of 19.91 months. The mini-open group exhibited significantly higher postoperative American Shoulder and Elbow Surgeons (ASES) scores compared to the arthroscopic group (P=0.002). Additionally, the mini-open group demonstrated a more significant improvement in ASES scores from preoperative to postoperative assessments (P=0.001). However, the arthroscopic method had a significantly longer operative time (P<0.001). Complications, including anchor placement issues, frozen shoulder, infection, and re-rupture, occurred in 17.3% of patients overall. Re-rupture rates were 13.5% for mini-open and 6.2% for full arthroscopic repair, with no significant difference between the two methods (P=0.317).Conclusions: Both the mini-open and arthroscopic methods yielded favorable clinical outcomes for rotator cuff tear treatment, but the mini-open group exhibited superior results. Surgeons should consider patient characteristics, tear attributes, and surgical expertise when selecting the appropriate technique.Level of evidence: III.

BACKGROUND: This study aimed to examine the relationships between the initial anatomic severity of hand, wrist and forearm injuries, as evaluated by the Modified Hand Injury Severity Score (MHISS), and each of the following parameters: disability rating and time to return to work. METHODS: In this study, 94 patients who underwent operations due to acute hand, wrist and forearm injuries were included. MHISS was used to assess the severity of the injury. Disability rates of the patients were calculated six months after injury in accordance with the 'Regulation on Disability Criteria, Classification and Health Board Reports to be Given to Disabled People'. The time to return to work was defined as the length of time (in days) between the injury and the patient's return to work. Spearman rank correlation analysis was performed to analyse correlations between the MHISS and each of the following: disability rates and time to return to work. RESULTS: The mean overall MHISS was 125.23 (5-880). The mean overall upper extremity disability ratio (UEDR) was 17.64 +/- 22.6 (range: 0-94), and the mean overall total body disability ratio (TBDR) was 10.57 +/- 13.45 (range: 0-56). Among the study population, 87 (92.6%) patients were able to return to their jobs. The mean overall time to return to work was 138.69 (range: 35-365 days). A statistically significant correlation was found between MHISS and UEDR, TBDR and time to return to work and UEDR, TBDR (p<0.001). CONCLUSION: As a result, as the initial injury severity increased, greater disability remained and the time to return to work increased. Predicting prognosis by determining the injury severity in the initial evaluation of patients may be important in predicting a patient's future permanent disability level, which can contribute to maintaining patient expectations at a reasonable level, thereby aiding in psychosocial support.
