Abstract
The glenoid baseplate survival is of paramount importance for the outcome of anatomical and reverse total shoulder arthroplasty procedures. Various prosthetic designs have been described and experienced to decrease the failure rates and improve patients’ satisfaction. Most of the orthopaedic surgeons have a great eagerness to implant and advocate the success of uncemented prosthetic components in arthroplasty procedures to avoid complications of cementing and troubles during the revision procedures. However, higher rates of failure were almost always reported for metal-backed glenoid components in the literature. Studies in the literature have consistently reported unsatisfactory results following implantation of uncemented metal-backed glenoid components. The most common complication of total shoulder arthroplasty (TSA) is the failure of the polyethylene glenoid component which accounts for the majority of the deleterious outcomes and manifests clinically by pain, loss of function, and presence of a clunking noise. High rates of radiolucency at the bone-cement interface were previously reported numbers of times in the literature. However, this fact does not always show up clinically as symptomatic loosening during the postoperative follow-ups. This chapter aimed to compare the mostly implanted materials named pegged and keeled glenoid components to provide a guide to the shoulder surgeons in decision-making for TSA procedures.
