[The femoral neck pseudarthrosis following medial femoral neck fracture. An indication for the vascularized pedicled iliac crest transplant].
Revascularisation surgery was performed in six cases following medial femoral neck fracture with femoral head necrosis and non-union of the femoral neck. A corticospongiosis pelvic graft supplied by the deep circumflex iliac artery was implanted as an autologous heterotopic pedicled transplant. The operative procedure was the same in all cases, since it was possible to lift out the pelvic graft from the same side as the affected hip joint, thus making a microvascular anastomosis unnecessary. Follow-up examination after 15-27 months revealed that, in all cases, osseous consolidation of the pseudarthrosis had been achieved and that further segmental collapse of the contour of the femoral head had been prevented. The angiographic studies performed during the examination demonstrated unimpeded circulation in the pedicle of the transplants in five of the six cases, as long as 3 months after the operation. For the first time it was possible in these five cases, by means of a transplant angiograph, to demonstrate integration of the graft into the biologically weak post-traumatic transplant region.
