title: Acetabular wall augmentation in selected patients with recurrent dislocation after THA.
abstract: We reviewed 42 patients operated with PMMA augmentation of the acetabular wall for recurrent posterior dislocation of cemented total hip arthroplasties with a cemented all-poly acetabular component. 38 patients never experienced subsequent dislocations after the procedure. 4 patients had recurrent dislocations, and two additional patients underwent a revision procedure due to aseptic loosening of the acetabular component. 1, 5 and 10 years survival of the prosthesis free of dislocation were 95%, 95% and 64% respectively. 90% of the patients were satisfied, four patients experienced pain and 3 patients sustained an infection. The procedure is simple, effective, takes less time and results in less blood loss compared to full revision surgery. It should be considered in cases of recurrent posterior dislocation in elderly patients.
