Abstract
The authors reviewed 21 patients who underwent triple pelvic osteotomy for severe Legg-Calvé-Perthes disease to evaluate their clinical, functional, and radiologic results. The mean age at presentation was 7 years 7 months (range 5-11 years). Seventeen hips were Herring group C and 5 were group B. All of them had "at risk" radiologic signs. A new technique of interlocking iliac osteotomy was used to provide extra stability, allow early weight bearing, and prevent inadvertent retroversion. The average period of follow-up was 30 months (range 1-5 years). The average gain in Harris score was 34.3 (range 4-55). The average gain in acetabular head index was 18% and that in center-edge angle was 22 degrees, more than reported for any other single surgical procedure for containment of the subluxed femoral head. Average gains in abduction, internal rotation, and flexion were 17 degrees, 12 degrees, and 28 degrees respectively. Longer follow-up is required to see the results at maturity, but the early results are promising.
