Shoulder Hemiarthroplasty with Nonprosthetic Glenoid Arthroplasty

»: Glenoid component wear and loosening are the principal failure modes of anatomic total shoulder arthroplasty (aTSA). »: The ream-and-run (RnR) procedure is an alternative glenohumeral arthroplasty for patients who wish to avoid the risks and limitations of a prosthetic glenoid component. »: During the RnR procedure, the arthritic glenoid is conservatively reamed to a single concavity, while the prosthetic humeral component and soft tissues are balanced to provide both mobility and stability of the joint. »: The success of the RnR procedure depends on careful patient selection, preoperative education and engagement, optimal surgical technique, targeted rehabilitation, and close postoperative communication between the surgeon and the patient. »: While the RnR procedure allows high levels of shoulder function in most patients, the recovery can be longer and more arduous than with aTSA. »: Patients who have undergone an RnR procedure occasionally require a second closed or open procedure to address refractory shoulder stiffness, infection, or persistent glenoid-sided pain. These second procedures are more common after the RnR than with aTSA.
