Stemless Shoulder Arthroplasty for Glenohumeral Arthritis with Underlying Varus Malunion of the Proximal Humerus - A Case Report with Mid-Term Follow Up

Abstract

We present a 65 year old right hand dominant female with a varus malunion of her right proximal humerus who went on to develop post-traumatic arthritis of her right glenohumeral joint refractory to years of conservative management. Due to inability to pass a stemmed humeral implant as well as concerns associated with a proximal humerus osteotomy, we performed a total shoulder arthroplasty using a stemless humeral implant. We present mid-term follow up at six years showing excellent range of motion, excellent functional scores, and radiographs. This is one of the only US based studies to our knowledge to report mid-term data on clinical and radiographic outcomes for the use of a stemless humeral implant during a total shoulder arthroplasty in the setting of a proximal humerus deformity
