摘　　要：目的探讨CR对兔椎体骨折愈合过程的评判价值。方法选年龄、体重均相近的健康成年雌性青紫兰兔21只,手术制成椎体骨折后,分别在骨折后的24h、72h、1周、2周、4周、6周、8周观察其愈合的CR表现,并与其病理学改变对照分析。结果随着骨折的修复,骨折椎体内的低密度骨折线逐渐被带状致密影所代替,骨折椎体密度增高最终恢复为等密度。骨折椎体的长度缩短,随着逐渐形成骨性愈合,其长度逐渐稳定。结论CR可通过对兔骨折椎体密度和长度的分析评判其愈合的程度。Objective To evaluate the value of X-ray in evaluating the healing process of vertebral fracture in rabbits. Methods Twenty-one healthy adult female rabbits with the same age and weight were selected to make the animal models of vertebral fracture by operation, then all rabbits were examined with X-ray at 24hours, 72 hours, 1 week, 2 weeks, 4 weeks, 6 weeks and 8 weeks ,respectively. X-ray manifestations and pathological appearances were analyzed comparatively. Results With the repairing of the fractured vertebra, the low dense fracture lines were substituted by hyper-dense strings ,the density of the fractured vertebra increased and recovered from hyper-density to equal density.The length of the fractured vertebra shortened, and with the healing of the fracture, the length of fracture vertebra was steadied. Conclusion X-ray has some value in evaluating the healing process of the rabbit by analyzing density of the callus and length of the vertebra.
