Glenoid Component Failure in Total Shoulder Arthroplasty

摘要: Glenoid component failure is the most common complication of total shoulder arthroplasty. components fail as a result their inability to replicate essential properties normal glenoid articular surface achieve durable fixation underlying bone, withstand repeated eccentric loads and glenohumeral translation, resist wear deformation. The possibility should be considered whenever arthroplasty has an unsatisfactory result. High-quality radiographs made in plane scapula axillary projection are usually sufficient evaluate status component. Failures prosthetic can understood terms itself, seating, fixation, effectively manage loading. An understanding these modes leads strategies minimize complications related
