• BACKGROUND
    • We performed a retrospective and descriptive study to determine the feasibility of proximal humerus derotational osteotomy in younger patients with significant humeral head depression, who may not be good candidates for shoulder arthroplasty.
  • METHODS
    • Rotational osteotomy was done on four patients with a mean age of 40 for locked posterior dislocation associated with a reverse Hill-Sachs lesion from 2000-2011. The average age was 40 +/- 11 years old and the average follow up was 22 +/- 8 months. Shoulder stability, range of motion, radiographic outcome and postoperative complications were assessed. Average follow-up was 22 months (range, 12-30 months) postoperatively.
  • RESULTS
    • The average range of motion of the shoulders at the final follow-up were as follows (Mean +/- Standard deviation): Abduction: 125 +/- 29°, Forward flexion: 135 +/- 17°, Internal rotation: 65 +/- 17°, External rotation: 62 +/- 10°. There were no wound or neurological complications and no dislocations. Patients were satisfied with their functional status and did not have any further symptoms of instability or rotator cuff dysfunction.
  • CONCLUSIONS
    • Proximal humerus derotational osteotomy for acute locked posterior dislocation of the shoulder can be a viable option for younger age group, which can facilitate rehabilitation for these patients by providing immediate stability.
