Modest results were achieved with a hemiarthroplasty and concentric glenoid reaming in young patients with end-stage glenohumeral arthritis and a biconcave glenoid. Younger age and stiffness were associated with worse outcomes. Given the high revision rate and the percentage of patients who had unsatisfactory results, this procedure should be performed only after careful patient selection. Patients who are willing and able to undergo aggressive physical therapy focused on achieving early range of motion are more likely to have a satisfactory outcome after humeral hemiarthroplasty with concentric glenoid reaming.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
