Abstract: | Osteoarthritis (OA) secondary to dislocation and dysplasia is a common problem in patients with cerebral palsy. The purpose
of this study was to evaluate the results of total hip replacement (THR) in ambulatory patients with cerebral palsy. Eighteen
total hip arthroplasties were performed in 16 ambulatory patients with cerebral palsy. The patient's mean age at surgery was
42 ± 8 years (range 32–58 years), and the mean follow-up was 10 ± 6 years (range 2–18 years). Data were obtained by a standardised
telephone interview. There was a significant postoperative reduction in pain on the NAS (narrative analogue scale) from 8.4
preoperatively to 1.1 postoperatively (p = 0.002). At follow-up no stem had been revised. Three cups were revised for aseptic loosening at two and six years, and
one cup was revised for recurrent dislocation of the hip. One hip was revised for infection 12 years after the index surgery.
One hip dislocated (three months postoperatively) and was treated by closed reduction. In ambulatory patients with cerebral
palsy and secondary osteoarthritis of the hip THR can provide long-term pain relief and improved function. The rate of long
term complications was moderate in this series; however, the dislocation rate was higher than in standard OA cases. |
