摘要：目的：通过动物实验探讨跨生长板钛板能否有效固定Salter-HarrisⅣ型骨骺损伤。方法：选取健康6-7周龄山羊24只,随机分为对照组、克氏针组和跨生长板钛板组,各8只。对照组不予处理;克氏针组和跨生长板钛板组采用山羊左右肱骨远端骨骺经克氏针钻孔骨凿凿开法造模,造模成功后分别用跨生长板钛板、交叉克氏针固定。3组于术后8周、12周每组随机抽取4只取材,对标本进行生物力学测试和比较。结果：对照组与跨生长板钛板组术后8周和12周的屈服强度、最大载荷、最大弹性模量及断裂点差异均无统计学意义（P〉0.05）,2组各项指标均明显优于克氏针组（P〈0.01）。结论：跨生长板钛板固定Salter-HarrisⅣ型骨骺损伤能够达到有效的生物力学固定强度,为骨骺损伤愈合提供一个相对稳定的环境,有利于骨骺损伤的修复。
Objective：To investigate the effects of the cross-growth titanium plate on fixing the type IV Salter-Harries epiphyses injury in animal experiment. Methods：Twenty-four healthy goats with the age of 6 to 7 weeks were randomly divided into the blank group, kirschner group and across-growth titanium plate group （ 8 goats each group ） . The animal models of the kirschner group and across-growth titanium plate group were established by kirschner drilling the distal epiphyses in two sides of humerus,which was fixed using across-growth titanium plate and kirschner,respectively. The biomechanical testing of 4 goats from each group after 8 or 12 weeks of operation were implemented and compared. Results：After 8 and 12 weeks of operation,the differences of the yield strength,maximum load,maximum elastic modulus and breaking point between blank group and across-growth titanium plate group were not statistically significant（P〉0. 05）,and each indicator in the two groups were better than those in kirschner group（P〈0. 01）. Conclusions：The treatment of typeⅣSalter-Harries epiphyses injury with cross-growth titanium plate can effectively meet the fixation strength of the bio-mechanics,which can provide a relatively stable setting to accelerate the repair process of the epiphyses injury.
