Anatomic Basis on Transposition of Iliac Bone Flaps Pedicled with Sartorius Muscular Fascia

Objective To discuss anatomic basis for transposition of iliac bone flaps between anterior superior iliac spine and anterior inferior iliac spine pedicled with sartorius muscular fascia and intermuscular septum vessels. Methods On 30 adult cadavers perfused with red emulsion,the sartorius muscular fascia and intermuscular septum vessels among the sartorius muscle,the femoris rectus muscle and the tensor muscle of fasci lata were observed.and the operations were imitated on 1 adult cadveric limb. Results The sartorius muscular fascia and intermuscular septum needed in clinical operation were limited to the point about 10cm descended form the spina iliaca anterior.The vessels of the sartorius muscular fascia and the iliac crest branches of ascending ramus of lateral femoral circumflex vessels were the supplied vessels.The pedicle length of the sartorius muscular fascia and intermuscular septum was 6～8cm. Conclusion The method can be used as a base vessel of the neck of femur.
