Abstract: We previously reported the mean 4-year outcomes of anatomic total shoulder replacement using an all-polyethylene, pegged, hybrid-fixation (bone ingrowth and cement) glenoid component. In the present study, we report on that patient cohort after another 4 years of follow-up (mean, 101 months; range, 77 to 146 months). At that time, the median American Shoulder and Elbow Surgeons (ASES) score was 92 points (interquartile range [IQR], 81.7 to 98.3) and the median Oxford Shoulder Score was 47 points (IQR, 41 to 48). Osseointegration, demonstrated by bone ingrowth between the flanges on the central peg as seen on coronal computed tomography (CT), was complete in 75% of the shoulders, partial in 21%, and absent in 4%. There were radiolucent lines at the bone-prosthesis interface on CT, with a median Yian score of 1 (IQR, 0 to 2; range, 0 to 18). The conclusion in the present study was that shoulder arthroplasty with an all-polyethylene, hybrid-fixation (bone ingrowth and cement) pegged glenoid component has durable clinical and radiographic outcomes at medium-term follow-up. Therapeutic Level IV. See Instructions for Authors for a complete description of levels of evidence.
