ransopition of vascularized fascia-lata-iliac bone with its periorteum composite graft was used inthe treatment of 20 cases of old fractures of femoral neck. Because the vascular bundie containing thedeep lateral femoral circumflex artery needed not to be dissected during operation, it reduced thechance to irritate the blood vessel and the implantation of the vaseularized composite graft with itsporicateum which wrapped around the neck of femur, it would improve the blood circulation of the femur and the fracture site, thus enhancing the fracture healing and giving the chance to prevent the development of avascular necrosis of femoral head.
