摘    要:目的:探讨股四头肌腱的生物力学特性,为其能否应用于临床前交叉韧带(ACL)重建提供实验依据.方法:取32例新鲜尸体的1cm宽股四头肌腱,按其解剖结构分为两柬:股直肌、股内、外侧肌腱舍为A束,股中问肌腱为B束,用游标卡尺测量两束的宽度及厚度,然后将两束置于电子万能试验机上分别测其生物力学指标.结果:A 束厚度为4.39±1.72mm,宽度为8.19±1.18mm,生物力学强度为685.67±227.09N,抗拉强度为17.00±3.48Mpa;B束厚度为3.06±1.47mm,宽度为7.10±2.03mm,生物力学强度为435.04±205.80N,抗拉强度为13.16±4.02Mpa.A束生物力学强度与ACL比较,差异有统计学意义(p<0.05);B束生物力学强度与ACL比较,差异有统计学意义(p<0.05).结论:股四头肌腱的生物力学性能不能满足ACL双束重建的要求,其在临床上应用于ACL双束重建的价值有待于进一步的深入研究.
Abstract:
Objective: To investigate the biomechanics of the quadrieeps tendon and to provide theoretical basis for double-bundle reeonstruction of anterior cruciate iigament(ACL). Methods: 32 quadriceps tendons (width lena) taken from fresh cadaver were dissected into 2 bundles according to the anatomy, one bundle including rectus femoris, vastus medialis and vastus lateralis was named A bundle and the other was named B bundle. The width and thickness of the A and B bundle were detected respectively with a Vernier caliper and the biomechanics were determined by WDW-30 election universal testing machine. Results: The thickness, width, ultimate load and ultimate tensile strength of bundle A were 4.39± 1.72mm, 8.19± 1.18mm, 685.67± 227.09 N and 17.00± 3.48 Mpa respectively, while for bundle B,which were 3.06± 1.47 ram, 7.10± 2.03mm: 435.04±205.80 N and 13.16± 4.02 Mpa. There was difference between bundle A and the ACL (p<0.05). Conclusion: The ultimate load ofbundle A was much lower than the the ACL and bundle Bwas also lower than the ACL.
