What does the pegged TSA glenoid Poly also refer to?

The term "pegged TSA glenoid Poly" refers to a specific design element in total shoulder arthroplasty, particularly concerning the glenoid component used in the procedure. In this context, the "pegged" description indicates that the glenoid component has several pegs or projections that help in stabilizing the implant within the glenoid cavity.

This design helps facilitate proper fixation to the bone and may aid in ensuring a stable and secure fit. The use of pegs can contribute to the overall success of the arthroplasty by enhancing the integration of the implant with the surrounding bone, potentially improving the longevity of the implant and function for the patient.

The other terms mentioned, such as "kegged," "flat," "longitudinal," and "anchored," do not accurately capture this specific feature of the pegged glenoid component and might refer to different aspects or types of glenoid implant designs. Understanding these terminologies can help differentiate the various strategies used in shoulder arthroplasty and their intended functions.
