Microvascular free transfer of iliac bone based on the deep circumflex iliac vessels

Abstract

The findings from dissections, injection studies, and angiograms of 180 specimens of the anterior portion of left and right iliac crests taken from 90 cadavers are reported. These findings suggested that the deep circumflex iliac vessels were suitable for use as a nutritive pedicle in microvascular free transfer of iliac bone. Therefore, the technique of microvascular free transfer of iliac bone based on these vessels was developed and applied clinically in 2 cases with good results. The advantages and disadvantages of using the superficial circumflex iliac vessels or the deep circumflex iliac vessels as the vascular pedicle for iliac grafts also are discussed.
