Anterior approach according to Ganz--surgical dislocation of hip joint.

The surgical technique of an anterior approach to the hip joint according to Ganz is described. The procedure preserves the deep branch of the medial circumflex artery, which, combined with greater trochanter osteotomy, allows for safe hip joint dislocation without a risk of avascular necrosis of the femoral head. This approach makes it possible to inspect the femoral head and the entire acetabulum. It is suitable for the treatment of early stages of coxarthrosis.
