Background

The short-term results of total shoulder arthroplasty with an inlay glenoid component performed by a single surgeon in patients with glenoid bone loss have previously been reported. The purpose of this study was to investigate the mid- to long-term clinical and radiographic outcomes of these patients.

Methods

We identified a cohort of patients who underwent total shoulder arthroplasty with an inlay glenoid component performed by a single surgeon between 2010 and 2019 for severe glenoid dysplasia and/or glenoid bone loss. Patients with a minimum of 2 years' follow-up were evaluated regarding preoperative and postoperative range of motion, radiographic findings, visual analog scale pain scores, and Single Assessment Numeric Evaluation scores.

Results

Overall, 39 shoulders in 33 patients were treated with an inlay glenoid component for severe glenoid bone loss.
Four patients were lost to follow-up, and 1 patient died with a well-functioning implant in place.
The final cohort included 34 shoulders in 28 patients (46.4% female patients [13 of 28] and 53.6% male patients [15 of 28]) with a mean age of 66.9 years (range, 58-81 years) and mean follow-up period of 68.3 months.
Of the 34 cases, 5 were revision cases.
One patient died following 2-year follow-up.
Of the shoulders, 10 were classified as Walch type A2, 4 were classified as Walch type B3, and 15 were classified as Walch type C; 5 shoulders were unable to be classified.
We observed statistically significant increases in range of motion (forward elevation, 38.1 [P < .001]; external rotation, 18.8 [P < .001]) and improvement in the Single Assessment Numeric Evaluation score (from 26.6 to 81.0, P < .001).
Two patients underwent conversion to reverse shoulder arthroplasty at 2.2 and 1.7 years postoperatively.

Conclusions

Inlay glenoid components provide a low rate of revision and improved clinical and functional outcomes at mid- to long-term follow-up.
