title: Proximal femoral osteotomies in children.
abstract: The aim of proximal femoral osteotomies (PFO) in children is to restore normal anatomy and optimal joint congruency to prevent medium and long-terms degenerative deterioration of the hip. They play an important role in the treatment of neurological subluxations or dislocations of the hip. Advances in modern imaging and surgical techniques have improved understanding of the anatomical factors associated with a number of disorders of the growing hip and their sequelae. The indications for isolated PFO or associated with other intra- or extraarticular procedures have become more rational and better adapted to the various architectural defects and the femoroacetabular impingements. Two types of osteotomies are described: intertrochanteric osteotomies (varus and valgus correction, valgisation, flexion, extension), and osteotomies of the greater trochanter, either simple or double with lengthening of the femoral neck. Primary stability of the osteosynthesis is the major problem, as it is often affected by osteopenia. The development of new implants (LCP plate) avoids this inconvenience, resulting in geometrically precise osteotomies and a more stable fixation. Even when it is correctly performed, articular congruence is not always managed by PFO alone, it is sometimes necessary to associate acetabular procedures.
