Failed Reverse Shoulder Arthroplasty: Case Example 2

Early failure of total shoulder arthroplasty (TSA) is mainly due to dislocation/instability of the implant most of the time linked to new trauma or surgical errors, whereas, in the long term, major causes of revision surgery are rotator cuff insufficiency and loosening of glenoid component due to osteolysis. Polyethylene wear has been shown to be an important long-term complication after anatomic TSA. It generates plastic wear debris that is responsible for osteolysis and severe glenoid bone resorption.
