自体移植骨块,通常取自髂骨的外上方。术后常有疼痛,血肿形成,短期内不能行走,以及骨量和外形上的不足等缺点。作者采用新的骨块切取法,即通过减少解剖肌肉,利用髂骨的内侧壁以及采用缝合法关闭供区缺损等措施,使并发症明显减少,而且切取的髂骨块较为理想。手术方法如下: 患者取仰卧位,术侧臀部垫高,将髂嵴外侧的皮肤向内侧推移,使切口位于髂嵴外3cm处。沿髂嵴粗隆外缘作4～6cm长的切口,为避开股外侧皮神经,切口至少要止于离髂前上嵴2cm处。
Autologous bone graft, usually taken from the top of the ilium. Postoperative pain, hematoma formation often can not walk in the short term, as well as the lack of bone mass and shape defects. The authors adopted a new method of cutting the bone, that is, by reducing the anatomical muscle, the use of the iliac medial wall and the use of suture closure for donor site defect and other measures to significantly reduce the complications, and the extracted iliac bone block is more ideal. Surgical methods are as follows: patients supine position, hip pad surgery side, the iliac crest outside the skin to the medial shift so that the incision is located 3cm outside the iliac crest. Iliac ridge along the outer edge of the tuberosity for 4 ~ 6cm incision, in order to avoid the lateral femoral cutaneous nerve, the incision at least only 2cm away from the anterior superior iliac crest.
