FEMORAL DEROTATION FOR INCREASED HIP ANTEVERSION - A NEW SURGICAL TECHNIQUE WITH A MODIFIED ILIZAROV FRAME

We describe a technique of femoral derotation osteotomy performed acco rding to the Ilizarov principles of percutaneous corticotomy and fixat ion with a frame. We performed 24 femoral osteotomies in 16 patients, four with cerebral palsy and 12 with idiopathic femoral anteversion. A ll had rapid union and there were few complications. The advantages of the method include early ambulation, good control of rotation and axi al alignment, and minimal scarring.
