In patients with glenohumeral osteoarthritis, normal glenoid version is distorted and difficult to estimate preoperatively. This study tests whether a standardized 3-D glenoid vault model — fit to the preserved endosteal contours of the arthritic scapula — can predict what the patient's native version would have been, without requiring a healthy contralateral shoulder as reference.
When planning glenoid component placement in total shoulder arthroplasty — especially with posterior glenoid erosion.
The 3-D vault model provides a patient-specific version target rather than defaulting to a population mean or arbitrary neutral axis; this is particularly valuable when the contralateral shoulder is also arthritic and cannot serve as a reference.
