The fate of free, pedicled and free vascularized cancellous iliac bone grafts and the effect on the healing of femoral osteotomy: an experimental study.

A new model for vascularized and nonvascularized iliac bone autograft transfer to a femoral shaft osteotomy site is presented in this experimental study. As demonstrated on roentgenograms taken at 4 to 6 weeks postoperatively, callus formation between vascularized grafts and recipient sites was 1.5 to 2 times faster than in the nonvascularized graft transfer.
