What factors should be assessed when evaluating glenoid wear patterns?

When evaluating glenoid wear patterns, the extent of wear and deformity type are critical factors to assess. This is because glenoid wear can vary significantly based on a patient’s specific pathology, such as osteoarthritis or previous injury, and it is essential to understand the degree of deterioration present. The extent of wear indicates how much of the glenoid surface has been compromised, which directly impacts the surgical approach, component selection, and overall surgical strategy during total shoulder arthroplasty.

Additionally, identifying the deformity type—whether it is primarily posterior, anterior, or a combination—provides insights into how the glenoid has adapted to stress and alters the options for reconstruction. This assessment is vital for planning the procedure effectively to restore function and achieve optimal alignment and stability post-surgery.

Other factors, while potentially relevant in a broader assessment of the patient, do not have the same direct impact on evaluating glenoid wear patterns specifically. Therefore, focusing on the extent of wear and the specific types of deformities ensures a targeted approach to surgical intervention.
