- Abstract
Background: There are different techniques for drilling the femoral tunnel in the anterior cruciate ligament reconstruction (ACLR), but their influence in the bone tunnel enlargement in unknown. The purpose of this study was to compare two different surgical techniques for evaluating femoral tunnel enlargement in ACLR. The hypothesis was that tunnel placement using the outside-in technique leads to less tunnel enlargement compared to the transtibial technique., Methods: Forty-four patients treated for ACLR between March 2013 and March 2014 were prospectively enrolled in this study. According to the surgical technique, subjects were assigned to Group A (Out-in) or Group B (Transtibial). All patients underwent CT examination in order to evaluate the femoral tunnel enlargement at four different levels. Moreover, all patients were evaluated with the Lachman test and pivot shift test, and the KT1000 arthrometer was used to measure the anterior laxity of the knee. A subjective evaluation was performed using the 2000 International Knee Documentation Committee Subjective Knee score, Lysholm knee score and Tegner activity scale. All patients were assessed after 24 months of follow-up., Results: At the final follow-up, there were statistically significant differences (p < 0.05) in femoral tunnel enlargement between the two groups at all four femoral levels in favor of the out-in group. No statistical significant differences were found in the objective and subjective clinical outcomes between the two groups (p > 0.05)., Conclusions: In ACLR with a suspension system, the outside-in technique leads to less enlargement of the femoral tunnel lower than the transtibial technique.

- Abstract
The present study reports the clinical results of excision of a symptomatic os trigonum using an endoscopic procedure in professional ballet dancers. The hypothesis was that posterior endoscopic excision of the os trigonum would be safe and effective in treating posterior ankle impingement syndrome related to the os trigonum. Twelve professional dancers underwent excision of a symptomatic os trigonum for PAIS using a posterior endoscopic technique after failure of conservative treatment. The patients were evaluated pre- and postoperatively according to the American Orthopaedic Foot and Ankle Society hindfoot scale score, the Tegner activity scale score, and the visual analog scale score. The surgical time, timing of a return to sports, patient satisfaction, and any complications related to the procedure were recorded. The average postoperative follow-up duration was 38.9 ± 20.6 (range 12 to 72) months. The mean Tegner activity scale score increased from 4.3 ± 0.8 (range 3 to 5) preoperatively to 9 ± 0.2 postoperatively (p < .05). The mean American Orthopaedic Foot and Ankle Society scale score increased from 67.8 ± 6.0 (range 58 to 76) preoperatively to 96 ± 5.1 (range 87 to 100) postoperatively, with 7 of 12 patients (58.3%) reporting the maximum score of 100 points (p < .05). The return to sports was 8.7 ± 0.7 (range 8 to 10) weeks. No major complications were recorded. The results of the present study demonstrate that the endoscopic excision of symptomatic os trigonum using a 2-portal technique after failure of conservative treatment is characterized by excellent results with low morbidity., (Copyright © 2016 American College of Foot and Ankle Surgeons.

Kienbock’s Disease, or lunatomalacia, has uncertain etiopathogenesis, it is more common in male from 20 to 45-year-old. The Lichtman’s classification is the most used by authors and it divides Kienbock’s Disease in 4 stages according to radiographic parameters. In early stages could be performed a conservative treatment, but failure rate is high; various surgical techniques are available in case of failure or higher stages. We report a case of a 26-year-old female volleyball player affected by stage I Kienbock’s Disease who underwent distal radius osteotomy core decompression synthesized with Carbon-Peek plate fixation. Follow-up was performed with clinical evaluation (ROM analysis, VAS score, Quick Dash Score), wrist radiographs and wrist MRI. (www.actabiomedica.it)

Background and aim: Fractures of the distal radius are a common injury and mal-union can occur in those managed non-operatively. This can cause significant functional limitations along with pain. A corrective osteotomy with the use of a volar locking plate aims to restore articular surface congruency and improve outcomes. We present our local experience with clinical, functional and radiological outcomes of corrective osteotomy using a fixed angle volar locking plate and bone graft for management of distal radius mal-union. Methods: Retrospective study. All adult patients. Both pre and post operatively clinical range of motion was recorded. Post operative PROMS was measure by DASH, MAYO and SF-12 and pain by means of a VAS measured from 0-10. Mean follow up period was at 15 months. Results: 32 patients underwent the studied procedure. 24F-8F. Mean age: 56. Radiological union of corrective osteotomy: 28 (88%) of patients. 4 patients required further operative treatment to achieve corrective union. No other reported complications post-op. Post-operatively flexion improved by 24 and extension 20. Pronation was improved by 24 and supination 22. Pain was improved from an average VAS pre-operative of 5.6 to 1.6 post-operatively. Mean DASH scored improved from 57.8 to 16.2 post-operatively and MAYO 38.5 to 58.6. The mean post-operative SF-12 score was 46.2 from 31. Conclusions: In this series of 32 patients (the biggest reported in the literature in our knowledge) a corrective osteotomy with fixed-angle volar locking plate for mal-united distal radius has shown to improve both clinical-radiological and patient reported outcomes and provide good results of the very few complications’ treatments.
