title: Bipolar shoulder arthroplasty for rotator cuff arthropathy.
abstract: Between July 1991 and February 1995, 33 patients underwent bipolar shoulder arthroplasty for painful rotator cuff arthropathy of the shoulder. Twenty-two of these patients have been followed for an average of 28 months (range 24 to 48 months) and comprised the study group. All patients had massive, irreparable rotator cuff tears and presented with preserved passive motion, good deltoid function, and obliterated glenohumeral joint surfaces. Function and comfort were dramatically improved in all patients, with an average increase in active forward elevation of 29 degrees and a gain in active external rotation of 39 degrees. There was one complication requiring reoperation at 4 years. Utilizing the UCLA and Swanson scoring systems, all patients were rated fair or better.
