Glenoid version has been correlated with tears within the rotator cuff. Cuff tear arthropathy is an evolution of multiple unhealed tendons ultimately resulting in pseudoparalysis. Although several factors are critical to allow tendon healing, we have observed that there is less glenoid version in patients with cuff tear arthropathy. This was compared to those with osteoarthritis where rotator cuff tears are uncommon. We hypothesize that patients undergoing inverse prosthesis generally have a near neutral glenoid. A single surgeons practice (JPW) was retrospectively reviewed for all cuff tear arthropathy and osteoarthritis patients undergoing primary shoulder arthroplasty. (Zimmer, Warsaw, IN). Glenoid version was measured by 2 fellowship trained shoulder surgeons. Inter and intra-class correlation was measured.Purpose
