The II type deformities according Kalamchi after avascular necrosis of the femoral
head is the most difficult for operative correction. We performed the triple pelvic
osteotomy in 18 cases with unsatisfactory development of acetabulum for creation of
"a stability stock» in a hip joint.The mean follow-up is about 7 years. For assessment
of outcome we used the classification of Severin with addition Zionts and MacEwen.
Clinical evaluation at the latest follow-up included leg length discrepancies, range of
motion and McKay system. 3 hips had an excellent result, 11 a good result and 4 a
fair result. The mean Viberg angle increased from 14 to 32. The mean leg length
discrepancy is 0,8 sm. 2 patients still had lameness after operative treatment. Using
of the triple pelvic osteotomy is justified at treatment of the II type deformities
according Kalamchi after avascular necrosis of the femoral head in children.
Advantages of operation are improvement of femoral head covering, increase
of stability and possibility further remodeling of hip joint.
