Unstable total hip arthroplasty (THA) defined by recurrent dislocations

1. Unstable total hip arthroplasty (THA)

The THA should be evaluated for component position via plain radiographs and advanced imaging in the form of CT scan.

Malposition component requires revision to THA with removal and replacement of the components into the appropriate position.

Detailed description of total hip replacement is beyond the scope of this module of the AO Surgery Reference.
