[Vascular pedicled pelvic bone span. Value of digital subtraction angiography in pre- and postoperative diagnosis].

The pedicled pelvic bone graft is a new operative technique for the treatment femoral head necrosis. 29 femoral head necroses were examined by i.a. DSA before a pedicled pelvic bone graft was implanted. 11 pedicled pelvic bone grafts were investigated postoperatively. The pre- and postoperative findings are presented. I. a. DSA is a valuable method for the evaluation of the vascularisation of the femoral head before and after surgery.
