Aim. Hip prosthesis for sequelae of acetabular fracture can be a challenging procedure, has a higher percentage of complications and give worse clinical results in respect to the same procedure when performed in other pathologies. Methods. We report the clinical and radiographical results of 38 hip prostheses implanted for acetabular fractures. At a mean follow-up of 27 months the mean Harris Hip score was 89. Results. In 3 patients dislocation occurred; in patients with big diameter heads it was not registered any case of dislocation. Six patients developed heterotopic ossification degree I or II of the Brooker classification. Two patients required revision for loosening of the acetabular component. Conclusions. Emispherical press-fit cups can be used in the majority of the patients. The use of big diameter heads seems to reduce the incidence of prosthetic dislocation.

Abstract
Aim. Hip prosthesis for sequelae of acetabular fracture can be a challenging procedure, has a higher percentage of complications and give worse clinical results in respect to the same procedure when performed in other pathologies. Methods. We report the clinical and radiographical results of 38 hip prostheses implanted for acetabular fractures. At a mean follow-up of 27 months the mean Harris Hip score was 89. Results. In 3 patients dislocation occurred; in patients with big diameter heads it was not registered any case of dislocation. Six patients developed heterotopic ossification degree I or II of the Brooker classification. Two patients required revision for loosening of the acetabular component. Conclusions. Emispherical press-fit cups can be used in the majority of the patients. The use of big diameter heads seems to reduce the incidence of prosthetic dislocation.
