Computerised tomography in non-treated congenital hip dislocation.
Computerised tomography, carried out in 5 non-treated cases of congenital dislocation of the hip, shows that the femoral head can move in a large anteroposterior cavity. When the hip is extended the common position of dislocation is lateral superior and slightly anterior to the acetabulum. When the hip is flexed (at a right angle), the femoral head is located posterior and slightly superior to the acetabulum. Dislocation reduction has always been possible. When the hip is flexed a large "click" takes place; whereas if the hip is extended, the "click" is less noticeable, or even absent.
