摘　　要：目的:探讨新西兰大白兔肋软骨膜对肋软骨自体异位移植后生物力学的影响,为临床上选取最佳肋软骨移植物提供理论依据。方法:6周龄新西兰大白兔6只,取单侧6、7、8带软骨膜肋软骨,每个标本随机分为等长两段,一段保留软骨膜,一段去除软骨膜,分别埋植于兔的背部两侧对称部位。于12周后取出两组埋植软骨,剥去带肋软骨膜者的软骨膜,埋植前不带肋软骨膜者不作处理。据试验机要求制成相应大小标准试件。采用SHIMADZU(日本,AGS-X型)试验机行拉伸、压缩和弯曲试验。结果:带软骨膜组肋软骨极限抗拉强度及最大拉伸应变、最大压缩强度及最大压缩应变、最大弯曲强度及弯曲破坏时间均大于不带软骨膜组,两组之间差异有统计学意义(P<0.05)。结论:带软骨膜肋软骨生物力学性能优于不带软骨膜者。Objective To study the differences of the cartilage with and without the perichondrium after autologous ectopic transplantation in healthy rabbits,in order to offer theory reference for clinic to make the best use of cartilage. Methods 6 rabbits at the age of six weeks.Each of them the sixth,seventh,and eighth costal cartilages with perichondrium were removed,and divided into two segments at the even length,one segment with perichondrium and the other non-perichondrium.They were buried under the skin of the back at bilaterally symmetrical parts.Two different groups of cartilages were took out after 12 weeks and removed the perichondrium of the cartilages that had it previously. Tensile,compressive and fiexural tests were conducted by using SHIMADZU material testing machine. Results The average maximum strength and the strain of tension,compression and flexion of the perichondrium group were higher than those in the non- perichondrium group （P〈0.05）. Conclusion Biomechanics of costicartilage with perichondrium are superior to those without it after autologous ectopic transplantation.
