Thirteen non-cemented hips prostheses implanted in 12 patients with an osteoartritis secundary to congenital dislocation and dysplasia of the hip were reviewed.Patients had a more than 2 years follow-up. The postero-lateral surgical approach was employed in all cases. On the acetabular side, we always used the PCA socket type. On the femoral side we implanted a PCA standard stem in 7 cases, mid stem in 3 cases and a long stem in 3. Acetabular bone autograft was added in 7 patients. In order to restore the original center of rotacion of the hip, in patients with a severe dislocation we perfomed also a shortening sub-trochanteric osteotomy; all the patients were evaluated pre and post-operatively with two separate forms. The first regarding the clinical evaluation, the second for radiographic assessment. All the patients were fully satisfied with the operation increasing dramatically their activity level. We obtained 8 excellent results, 3 good, 1 fair and 1 poor. One case required a revision for a severe heterotopic bone formation about 4 years after the first implant. We had a diaphyseal femoral fracture as the sole inly an intraoperative complication.
