摘要:

背景:采用自体瘤骨灭活再植修复骨肿瘤切除后骨缺损具有明显优势,在其应用前主要采用水煮、乙醇浸泡、低温冷冻、微波、放射等灭活,但均有不足之处。
目的:观察高温高压灭活自体骨修复大段骨缺损的效果与可行性。
方法:建立新西兰大白兔双侧桡骨远端骨缺损,右侧以高温高压灭活自体骨原位再植修复,作为实验组;左侧以自体骨原位再植修复,作为对照组。术后6,12,24周进行双侧桡骨大体观察、X射线检测、骨放射性核素扫描检测及组织学检查。
结果与结论:术后24周时,X射线显示两组均为正常骨愈合。术后24周骨放射性核素扫描检测显示,实验组修复骨段放射不均,两端浓聚仍稍高,中间减低,对照组接近正常。术后24周组织学观察显示,实验组缺损处大部分为骨小梁,部分编织骨不成熟,与对照组术后12周时的表现相类似;对照组基本为正常骨质。表明高温高压灭活自体骨可用于修复长段骨缺损,但存在延迟骨愈合。

Abstract:

BACKGROUND: Inactivated autologous replantation in repair of bone defects after bone tumor resection has obvious advantages. Boiling, alcohol soaking, cryogenic freezing, microwave, radiation and other methods have been used for inactivation; however, they all have shortcomings.

OBJECTIVE: To study the effect and feasibility of high temperature and high pressure inactivated autologous bone in repair of large segmental bone defects.   
METHODS: Bone defect models of bilateral distal radius were established in New Zealand white rabbits. Bone defect at the right side was repaired by high temperature high pressure inactivated autologous bone via in situ replantation, as experimental group. Bone defect at the left side was repaired by in situ bone replantation, as control group. The general observation of bilateral radius, X-ray detection, bone radionuclide scan test and histological examination were conducted at the 6th, 12th and 24th weeks after surgery.
RESULTS AND CONCLUSION: At the 24th week after surgery, X-ray films showed normal bone healing in these two groups. At the 24th week after surgery, bone radionuclide scan test showed that in the experimental group, the radiation on the repaired bone segments was uneven; the concentrations of nuclear elements were still slightly higher on both ends, but decreased in the middle area; and the concentration in the control group was closed to normal. At the 24th week after surgery, histological observation showed that there were a majority of trabecular bone tissues in the bone defect area of the experimental group, and some woven bone tissues were immature, which was similar to the performance of the control group at the 12th week after surgery; and normal bone was visible in the control group. These results demonstrate that high temperature and high pressure  inactivated autologous bone can be used to repair long segmental bone defects, but can result in delayed bone healing.
