We review the early results of 13 patients who underwent hip arthroplasty as the initial treatment following acetabular fracture. The indications for performing THA over open reduction and internal fixation included fractures of poor prognosis, dome comminution, femoral head damage and comorbidity. Fractures were fixed in a limited fashion and an uncemented Harris-Galante cup was inserted with bone grafting. All femoral components were cemented Exeters.

There were two deaths. The first in the immediate post-operative period due to massive pulmonary embolism and the second in the early rehabilitation period due to pre-existing respiratory problems.

The remaining 11 patients were assessed at an average of 37 months (13–68). The mean Charnley hip score was 15 (8–18) and the mean Harris hip score 82 (33–100). One acetabular cup had loosened accounting for the lowest scores and awaits revision. All fractures united by 6 months and all other components appeared stable at radiological review. Technical difficulties of this procedure will be discussed.
