Behavior of the proximal femur during the treatment of congenital dysplasia of the hip: a clinical long-term study.

The influence of the acetabular cover on the development of the proximal femur during the treatment of congenital dysplasia of the hip was studied in 47 children (58 hips) with a follow-up of 22 years. Varus osteotomy failed to correct hip dysplasia in 33 hips of 27 children. Chiari osteotomy was followed by a positive anti-Chiari effect (oval shaped acetabulum with proximal migration of the femoral head) in 15 children (20 hips). In five children (five hips) with coxa vara due to avascular necrosis, the anti-Chiari effect was negative. The combination of Chiari and varus osteotomy before the age of 8 years was followed by a positive anti-Chiari effect and recurrence of valgus deformity in seven of eight hips. The long-term failure of the varus and Chiari osteotomy, together with a review of clinical and experimental surveys, led us to prefer the acetabular redirectional osteotomy.

Chiari osteotomy of the pelvis: a long-term study.

We evaluated 104 osteotomies of the pelvis after an average of 18 years: 48% of patients had hip joint pain, 15% had low back pain, 41% had restricted movement, 74% had a positive Trendelenburg sign, and 77% had limb length discrepancy greater than 1 cm. We also followed the anti-Chiari effect, the influence of the osteotomy on narrowing the birth canal, and deterioration of the opposite acetabulum. We showed that the optimum indications for Chiari osteotomy are severe instability of the hip joint and an irregular femoral head.
