简要总结
This retrospective cohort study aims to evaluate the clinical outcomes of patients who underwent arthroscopic shoulder stabilization using a bone block technique for chronic recurrent shoulder dislocations. The study will assess complications, reoperations, and functional outcomes measured by the Western Ontario Shoulder Instability (WOSI) score. Patients operated on within the past 1-8 years will be included. Data will be collected through structured telephone interviews and medical record reviews.
详细描述
Background Chronic recurrent shoulder dislocation presents a significant challenge in orthopedic surgery, with potential long-term consequences for patients' functionality and quality of life. Arthroscopic stabilization using a bone block harvested from the iliac crest, without screw fixation, is a relatively new technique designed to reduce the risk of recurrence by improving the anatomical integrity of the shoulder joint.
Indications for shoulder stabilization surgery with a bone graft, also known as the bone block procedure, are based on classical criteria considering both anatomical and functional aspects of shoulder instability. These criteria include recurrent anterior shoulder dislocations that do not respond to conservative treatment such as physical therapy, significant glenoid bone loss, Hill-Sachs lesions, or failed previous stabilization surgery, such as a Bankart repair, where patients continue to experience instability or recurrent dislocations. Bone block stabilization may also be indicated in patients with particularly high demands for shoulder function and stability, such as those engaged in activities or occupations with a high risk of shoulder dislocation.
The bone block procedure addresses these issues by transferring a segment of bone from the iliac crest to the glenoid defect, thereby increasing the articular surface area. Simultaneously, the anterior joint capsule is tightened and reinforced, and the infraspinatus tendon is secured into the Hill-Sachs defect (remplissage) to enhance shoulder stability. This procedure is typically performed when more conservative methods have failed to provide adequate stability or when the anatomical conditions of the shoulder suggest that other techniques are unlikely to yield satisfactory results.
This study aims to evaluate the long-term outcomes of this surgical method.
Objective The primary objective of this study is to evaluate the clinical outcomes of patients undergoing arthroscopic shoulder stabilization with a bone block for chronic recurrent shoulder dislocations. The focus will be on complications, reoperations, and functional outcomes assessed using the Western Ontario Shoulder Instability Index (WOSI).
