The purpose of this study was to evaluate the short-term clinical and radiographic outcomes of humeral hemiarthroplasty and concentric glenoid reaming ("ream and run" procedure) and to compare the outcomes with those of total shoulder arthroplasty (TSA) for glenohumeral arthritis. Patients with glenohumeral arthritis who underwent the ream and run procedure with a minimum follow-up of 2 years were retrospectively reviewed. The primary outcome was revision to TSA. Secondary outcome measures included functional outcome scores, range of motion, and radiographic assessment. The outcome measures were compared with those of age- and sex-matched control patients who underwent anatomic TSA during the study period. One patient in the ream and run group required revision to TSA 14 months after the surgery because of excessive shoulder pain. There were significant improvements in the postoperative outcome scores and range of motion and external rotation in the ream and run group. Postoperative radiographs showed concentric glenoids without posterior subluxation in all except 1 shoulder. The outcome measures in the ream and run group were similar to those in the TSA control group except for active forward elevation and external rotation. The ream and run procedure provides improved pain relief and shoulder function at short-term follow-up for patients with shoulder arthritis. [Orthopedics. 2018; 41(6):e854-e860.].
