Does reverse shoulder arthroplasty for XXXX of the proximal humerus reduce impairment?

@entity5 @entity1 @entity281
BACKGROUND: Normal function of the upper limb is seldom restored after limb-sparing surgery for @entity5 of the proximal humerus. The literature suggests superior shoulder function is achieved in the short term with reverse total shoulder arthroplasty compared to other techniques when performed for conditions with rotator cuff deficiency. It is unclear whether this superiority is maintained when reverse total shoulder arthroplasty is performed for @entity5 . QUESTIONS/PURPOSES: When performed for @entity5 , we determined whether reverse total shoulder arthroplasty restores function and improves motion, the complications associated with the surgery, and whether reverse total shoulder arthroplasty with autologous grafting is associated with bone resorption. @entity1 AND METHODS: We retrospectively reviewed 14 @entity1 who had undergone reverse total shoulder arthroplasty for @entity5 of the proximal humerus. Four @entity1 died, leaving nine @entity1 for review. The surviving @entity1 were evaluated clinically and radiographically. The minimum followup was 0.6 years (mean, 7.7 years; range, 0.6-12 years). RESULTS: At last followup, mean active abduction was 157   and mean functional Constant-Murley score was 76%. One @entity1 had a @entity281 and one developed a loose prosthesis; both were treated with single-stage exchange. At last followup, both @entity1 had reasonable function without evidence of @entity281 or loosening. Radiographic graft resorption was seen in all but one @entity1 . CONCLUSIONS: Our observations suggest, at medium-term followup, reverse total shoulder arthroplasty is a reasonable option for @entity5 of the proximal humerus. It has low morbidity, restores a mean active abduction of 157  , and limits the impairment of activities of daily living. LEVEL OF EVIDENCE: Level IV, therapeutic study.
