【 摘 要 】

BackgroundDislocation is a challenging complication after reverse shoulder arthroplasty (RSA). We sought to evaluate the outcome of nonoperative and operative management of the dislocation after primary and revision RSA.MethodsBetween 2006 and 2013, dislocation occurred in 12/1081 primary RSAs (1.1%) and 15/342 revision RSAs (4.4%). Seventeen (69%) shoulders dislocated within 3 months of surgery. Ten (68%) patients underwent revision RSA for prosthetic instability. Mean age was 69 years, and mean follow-up after index RSA was 4 years.ResultsClosed reduction and bracing achieved a stable shoulder in 60% (3/5 patients) after primary and 20% (1/5 patients) after revision RSA dislocation. Operative management achieved a stable shoulder in 88% (7/8 patients) of primary and 64% (7/11 patients) of revision RSAs (P = .40). Overall, 9 shoulders (33%) had persistent instability at the final follow-up: 2/12 (17%) primaries versus 7/15 (47%) revisions (P = .08). Preoperative prosthetic instability was the main risk f...
