[Angiographic control of treatment of femur head necrosis with a pedicled pelvic bone graft].

A new operative method is introduced in the therapy of the idiopathic necrosis of the femoral head. This operation is based on the idea, that ischaemic processes play an important role in the origin of the idiopathic necrosis of the femoral head. The transplantation of a pedicle bone graft should provide a good arterial supply. 28 Preoperative superselective angiographies of the A. circumflexa femoris medialis showed pathological findings in 17 cases. A good supply of the bone graft was found in 4 from a total of 7 postoperative angiographies of the reset A. circumflexa ilium profunda.
