摘要
本文在8具防腐固定的成人标本上,切取跟腱和临床上常用来修复断裂跟腱的腹直肌前鞘,(足母)展肌肌腱和髂胫束等材料,进行单向拉伸破坏试验。试验结果表明:跟腱和(足母)展肌肌腱的最大拉伸力分别为210.6±26.5kg 和64.8±6.8kg:宽度为1cm 的髂胫束和横向腹直肌前鞘的最大拉伸力分别为29.5±7.6Kg 和10.1±3.8kg。按人体单足足尖站立时跟腱承受的拉力为1.2倍体重,本文给出了修复材料的应用条件。另外,横向腹直肌前鞘的最大拉伸力为身长方向的5倍多,故采用腹直肌前鞘修复跟腱时应沿横向取材。
The Achilles tendon and three no-rmally used autogenous grafts,theanterior layer of sheath of rectus mu-scle,the iliotibial tract and the tendonof abductor of great toe,which weretaken from the lower extremities ofeight cadavers,were tested with aSWD-10 testing machine.The averagemaximum tensile loads of the Achillestendon,the tendon of abductor of gr-eat toe,the anterior layer of the she-ath of rectus(10mm in width),andthe iliotibial tract(10mm in width)are 210.6kg,64.8kg,10.1kg and 29.5kg respectively.The Maximum tensileload of the anterior layer of sheathof rectus muscle is 4 times largeralong the transverse axis than that al-ong the longitudinal axis of the body.By statistic analysis of the talocrualjoint,the tensile load in the Achillestendon is about 1.2 times of the bodyweight in the position of single toe tipstanding.The methods in Achilles te-ndon restoration with different auto-genous grafts are discussed.
