BACKGROUND: Polio infection can often lead to orthopedic complications such as @entity625 , @entity170 , @entity425 , @entity85 , and chronic instability of the joints. The purpose of this study was to assess the outcomes and associated complications of arthroplasty in shoulders with sequelae of @entity3328 . METHODS: Seven @entity1 (average age, 70 years) were treated between 1976 and 2013 with shoulder arthroplasty for the sequelae of polio. One @entity1 underwent reverse shoulder arthroplasty, 2 had a hemiarthroplasty, and 4 had total shoulder arthroplasty. Average follow-up was 87  months. Outcome measures included @entity158 , range of motion, and postoperative modified Neer ratings. RESULTS: Overall @entity158 scores improved from 5 to 1.6 points (on a 5-point scale) after shoulder arthroplasty. Six shoulders had no or mild @entity158 at latest follow-up, and 6 shoulders rated the result as much better or better. Mean shoulder elevation improved from 72   to 129  , and external rotation improved from 11   to 56  . Average strength in elevation decreased from 3.9 to 3.4 postoperatively, and external rotation strength decreased from 3.9 to 3.3. This, however, did not reach significance. Evidence of muscle imbalance with radiographic instability was found in 4 shoulders that demonstrated superior subluxation, anterior subluxation, or both. This remained asymptomatic. No shoulder required revision or reoperation. CONCLUSIONS: Shoulder arthroplasty provides significant @entity158 relief and improved motion in @entity1 with sequelae of @entity3328 . @entity425 may be responsible for postoperative instability, and careful selection of the @entity1 with @entity2045 muscles must be made.
