Hip dysplasia is a relatively common congenital malformation for which hip arthroplasty offers one viable solution. The possibility of obtaining satisfactory results is closely related to knowledge of the anatomopathologic characteristics of the dysplastic hip. The various classifications of dysplasia are all based on the position of the head of femur with respect to the pelvis, since this is the parameter that most influences choices in prosthetic reconstructive surgery. This study examines the alterations of the acetabulum and the femur, the problems related to determination and restoration of a correct center of hip joint rotation, the changes that can affect the soft tissues and the consequences a dislocated hip can have on the spine and the knee.
A preoperative plan that takes into account the possible difficulties that may be encountered and the potential solutions available to the operator is an indispensable tool to achieve satisfactory results in patients with developmental dysplasia of the hip.
