Abstract
Custom glenoid baseplates have been introduced to address severe glenoid bone loss in the setting of shoulder arthroplasty. The purpose of this study is to evaluate and report clinical outcomes, radiographic assessment of baseplate fixation, and post-operative complications in patients treated with a reverse total shoulder arthroplasty (rTSA) and the custom Zimmer Biomet Comprehensive Glenoid Vault Reconstruction System (VRS) in the setting of severe glenoid bone loss. Patients who underwent rTSA (primary or revision) using the Zimmer Biomet Comprehensive Glenoid VRS from 2016 to 2025 were identified. Data collection included patient demographics, clinical outcomes, and complications. Exclusion criteria included any patients who did not complete follow-up after surgery. Eighteen patients (61.1% females) had a mean age of 71.4 years at surgery. Mean follow-up time was 27.4 months. Fourteen (77.8%) patients had prior arthroplasty, and 4 (22.2%) patients underwent primary arthroplasty. The durations from computed tomography scan and office visit to surgery were 4.9 months and 3.9 months, respectively. From pre-operatively to 1-year post-operatively, forward flexion improved from 45° to 128° (P < .01), external rotation at the side improved from 7° to 35° (P < .01), and external rotation in abduction improved from 26° to 84° (P = .04). The Patient-Reported Outcomes Measurement Information System (PROMIS) pain score improved from 66 to 53 (P < .05), while the depression and upper extremity function scores did not improve. There were 4 complications requiring revision surgery (22.2%), including 3 dislocations and 1 baseplate failure. rTSA with the VRS custom glenoid baseplate can improve early range of motion and pain in patients with severe, uncontained glenoid bone defects. Despite the severity of the pathology, complications specific to the custom baseplate are low, while the overall surgical complications and rates of subsequent revision surgery are moderate.
