摘要
目的探讨将髂骨再塑形为预期骨解剖形态的可行性。方法按预期骨的解剖形态制模(如管状骨),按照宽=1/2股骨周长、长=股骨缺损段的长度取髂骨块,经内、外板间剖开髂骨块,在圆柱体上将内、外板卷制成拱状(有微骨折,但仍保持连续),将拱状骨皮质面向模具内壁,剖开面向模具轴芯装入模具内,拱状骨与模具轴芯间填塞松质骨,将模具包埋于髂骨取骨处,克氏针固定模具。结果 CT扫描显示髂骨在预制的模具内塑形良好。结论利用模具可将髂骨按预期骨的解剖形态进行再塑形。
Objective To investigate the feasibility if reshaping iliac bone into expected bone anatomy morphology. Methods A die was made according to the anatomy morphology of expected bone. The width is half of the circumference of tubular bone. The length equals to the length of the tubular bone. The iliac block was split between the outer and inner plate. On the surface of cylinder,the outer and inner plate of the iliac block were rolled into arch respectively. Microfracture within the bone was performed successively. To control the cortical surface towards the internal wall of the die and the dissected surface towards the axis of the die,the arch bone was encased in the die. The cancellous bone was impacted into the cavity between the arch bone and the axis of the die. The die with the impacted bone was implanted in the iliac region and fixed with kirscher wire at the remained iliac crest. Results The effect of the iliac bone reshaping in the prefabricated die is perfect under the CT scan. Conclusion According to the anatomy morphology of the expected bone,iliac bone can be reshaped by using the prefabricated die.
