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).

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.

The conservative treatment of the fractures and dislocations of the extremities in children.

Both authors have dedicated most of their time since 1948 to the treatment of fractures in children. On the basis of their experience they are therefore submitting to the medical public those methods and results of the conservative treatment of fractures and dislocations in children which stood the test of time. The experiences of both authors as well as successful therapeutic methods of other surgeons are discussed in this book.
