Shoulder hemiarthroplasty with concentric glenoid reaming may significantly improve subjective function in younger patients, according to investigators from Northwestern University and University of Washington.
Matthew D. Saltzman, MD, and colleagues studied 65 shoulders in patients aged 55 years or younger who had glenohumeral arthritis treated with shoulder hemiarthroplasty and concentric glenoid reaming. The patients detailed their shoulder function and comfort at pre- and postoperatively. In addition, 22 shoulders had follow-up radiographs for evaluation. The investigators followed the patients for at least 2 years or until they underwent a revision procedure, according to the study abstract.
The follow-up revealed that nine shoulders underwent revision procedures. The investigators discovered that the number of Simple Shoulder Test functions in the unrevised shoulder group increased from a mean of 4.1 preoperatively to a mean of 9.5 at an average of 43 months postoperatively. The radiographic follow-up of 22 shoulders showed an average medial glenoid erosion of 1.1 mm at an average of 44 months postoperatively.
