Differences in Measurement of Glenoid Morphology Between Radiographs and Computed Tomography

Plain radiographs may overestimate shoulder β angle and inferior glenoid resection. In addition, inferior glenoid resection depth necessary to achieve a neutral baseplate, as measured on both radiograph and CT, would lead to overresection of the glenoid, putting patients at risk for implant subsidence. We further found that there may be differences in glenoid inclination based on patient sex.
