[Acetabular dysplasia:an experimental study].
Abstract
OBJECTIVE: To demonstrate whether acetabular dysplasia represents a primary feature of congenital dislocation of the hip or secondary defect. METHOD: The capsule of twelve puppies aged five to nine weeks was incised and the ligamentum teres was completely severed under anaesthesia. A part of gluteal medium muscle was implanted in the acetabulum and the head of the femur was dislocated from acetabulum. Roentagenogram was made three weeks after dislocation in all animals. RESULT: As early as three weeks after dislocation, acetabular dysplasia was clearly noted in all animals. There was more acetabular obliquity and increase of acetabular index. CONCLUSION: The acetabular dysplasia is the result but not the cause of congenital dislocation of the hip. This result provides probably support for the concept of developmental dislocation of the hip.
