We report 16 patients (18 hips) treated between 1997 and 1999. The average age was 5 years and 3 months (range, 2–9 years). Of all the hips evaluated, 13 (72%) corresponded to diplegic patients and 5 (28%) to tetra-plegic patients. The surgical plan consisted on femoral osteotomy combined with Dega pericetabular osteotomy coupled with adductor and psoas tenotomy using as a variable the reduction of the hip by the anterior approach depending on each case. We used the following criteria to evaluate results: 1 – pain, 2 – abduction range, 3 – Reimmers index, 4 – acetabular index.

Diplegic patients had good (78%), fair (12%) and poor (12%) results. Tetraplegic patients had good (25%), fair (50%) and poor (25%) results in this short follow up. On analyzing the cases, we observed an adequate development of the neurologic hips when using the acetabuloplasty with the Dega technique because it minimized the risk of coverage loss, as commonly seen in these kind of patients due to the progressive valgus during the postoperative period.
