Persistent glenoid component retroversion is associated with radiolucency as measured with a minimal radiation technique after total shoulder arthroplasty

Introduction: Post-operative glenoid retroversion has been shown in biomechanical, finite element analysis, and clinical studies to be related to the development of radiolucency and component loosening, one of the most common causes of failure after total shoulder arthroplasty (TSA). We analyzed version correction after TSA and the associated risk of developing glenoid component radiolucency at minimum 2-year follow-up. A minimal radiation method was validated in a cadaveric model and utilized in a clinical series to measure post-operative glenoid component version using routine post-operative X-rays, pre-operative CT scan, and a software algorithm.
