Long-Term Outcome of Rockwood Capsular Shift for Recurrent Shoulder Dislocation
Bibliographic record
Abstract
PURPOSE: To review the long-term outcome of Rockwood capsular shift for recurrent shoulder dislocation secondary to trauma. METHODS: Records of 30 males and 4 females who underwent Rockwood capsular shift for recurrent (≥2 episodes) anterior shoulder dislocation were reviewed. An additional Bankart repair with different techniques was performed in 24 of the patients by 2 different surgeons. The outcome was assessed using the Western Ontario Shoulder Instability Index (WOSI) and the Western Ontario Osteoarthritis of the Shoulder (WOOS) index questionnaires, the modified Rowe score, and the Constant-Murley score. Shoulder range of motion (ROM) was measured. Degenerative joint changes were evaluated on radiographs. RESULTS: During a mean follow-up of 13 (range, 10-16) years, 6 (18%) patients had a mean of 1.2 recurrent dislocations. Four of the patients reported a traumatic event during recurrent dislocation. Of the 6 patients, 3 had undergone a Bankart lesion repair. Better Rowe and adjusted Constant scores were associated with lower age at first dislocation, at the index surgical procedure, and at follow-up. Four patients developed glenohumeral osteoarthritis: 2 were mild or moderate and 2 were severe and symptomatic. Glenohumeral osteoarthritis was associated with follow-up duration (p=0.03) and poorer Rowe score (p=0.012), adjusted Constant score (p=0.001), and WOOS score (p=0.006). CONCLUSION: Rockwood capsular shift can preserve shoulder ROM, with rates of recurrent dislocation and degenerative joint changes comparable with other techniques.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
