Cementless Total Hip Replacement in Patients With Developmental Dysplasia of the Hip

$25.00

ABSTRACT: This study was conducted to evaluate the clinical and radiographic results of 22 total hip replacements done in 17 consecutive patients for coxarthrosis due to developmental dysplasia or dislocation of the hip. All operations were done using an anterior approach  without trochanteric osteotomy. Standard cementless prostheses were used in all cases. There  was no custom-designed prosthesis used. The acetabular cup was placed in an anatomic  position in the true acetabulum in every case. Bulk autograft was necessary to reconstruct the  deficient acetabular roof in only 2 hips. The average follow-up was 63 months (range, 40  months to 95 months). The average Harris Hip Score was improved from a preoperative value  of 35 (range, 24 to 46), to 96 (range, 79 to 100) at final follow-up. To date, no revision has been  one. Three hips showed radiographic evidence suggestive of aseptic loosening (2 stems  and 1 cup), but the clinical results remain satisfactory. There is no incidence of dislocation,  sciatic nerve palsy, or infection.
