Polyethylene wear can lead to osteolysis of the bone surrounding the glenoid, humeral and other components. This can result in insufficient bone stock or poor quality bone for re-implantation.
There is a tendency to treat failed anatomic total shoulder arthroplasties with revision to a reverse total shoulders arthroplasty. However, these revisions can be complicated due to intraoperative fracture, difficulty in baseplate fixation, postoperative components loosening, instability and neurologic injury.
Some cases of failed aTSAs can be successfully rewritten to hemiarthroplasty.
Revision of total shoulder arthroplasty and hemiarthroplasty: results after a mean 5-year following-up examined the results of patients who had undergone a conversion from aTSA into HA. In all 29 cases, intraoperative glenoid/humeral component leakage was observed.
76% of patients were satisfied with this procedure. 87% of patients experienced pain relief, with their mean pain scores increasing from 6.2 to 3.0. Scores on the Simple Shoulder Test (SST), improved from a median of 4.1 to 7.3. 62%…
