Virtual planning of shoulder arthroplasty has gained recent popularity. Combined with patients specific instrumentation, several systems have been developed that allow the surgeon to accurately appreciate and correct glenoid deformities in version and inclination. While each virtual software platform utilizes a consistent algorithm for calculating these measurements, it is imperative for the surgeon to recognize any differences that may exist amongst software platforms and characterize any variability. A case-control study of all CT scans of patients previously pre-operatively planned using MatchPoint SurgiCase® software were uploaded into the BluePrint software. The cohort represents surgical planning for total shoulder arthroplasty and reverse shoulder arthroplasty with varying degrees of glenoid deformity. Glenoid version and inclination will be recorded for each CT scan using both software platforms.Background
