FUNCTIONAL OUTCOME OF WEBER OSTEOTOMY IN CHRONIC ANTERIOR GLENOHUMERAL DISLOCATION IN YOUNG PATIENTS.

OBJECTIVE: This study aimed to evaluate the functional outcomes of humeral head derotational osteotomy according to the Weber technique as a therapeutic alternative for the treatment of chronic anterior shoulder dislocation in young patients. METHODS: This prospective case series included patients younger than 50 years who underwent clinical and radiographic evaluation. Outcomes were assessed using plain radiographs, computed tomography (CT), the Visual Analog Scale (VAS) for pain, the 36-Item Short Form Health Survey (SF-36), and range of motion measurements. The mean age of the participants was 47.67 years. RESULTS: The procedure resulted in a significant reduction in pain, with a mean decrease of 5.7 points on the VAS, as well as improvements of 30° in extension and 28° in external rotation (p < 0.05). The SF-36 demonstrated an average improvement of 27 points in overall quality of life and functional status, and 54 points in the pain domain. No cases of recurrent dislocation were observed. CONCLUSION: Weber humeral head derotational osteotomy provides satisfactory functional recovery, significant pain relief, and may be considered a viable treatment option for chronic anterior glenohumeral dislocation in young patients.
