【摘要】 目的通过动态观察不同缝合方法修复肌腱在愈合过程中的生物力学特征。方法将 140只鸡随机分为 A、 B两组，每组 70只。两组均以左侧为正常肌腱对照侧，右侧为肌腱损伤修复实验侧。 A组实验侧第 2～ 4爪分别采用“ 8”字缝合法、改良 Kessler缝合法及 Bunnell缝合法， B组实验侧第 2～ 4爪分别采用 Kleinert缝合法、 Tsuge双套圈式缝合法及 Ikuta缝合法。在术后 0(术毕 )、 3、 7、 14、 21、 28、 42d每组处死动物 10只，收集双侧第 2、 3、 4爪深屈肌腱，进行力学强度测试。结果无论何种修复方法，其缝合后的初始强度和愈合 6周后的强度都远低于正常肌腱； Tsuge法缝合的肌腱 Pmax在愈合过程中持续上升，于术后 42d在各组中最高；改良 Kessler法缝合的肌腱虽在术后 42d略低于 Tsuge法缝合组，但在愈合过程中平稳上升。结论 Tsuge缝合法和改良 Kessler缝合法是最佳的肌腱修复方法。更多还原

【Abstract】 Objective To identify the best techniques for tendon repair .Methods 140 chickens were divided at random into two groups :Group A and Group B(each of 70 chickens).In both groups ,the left served as control and the right claw was used for tendon injury repair In group A,cross- stitch suturing ,modified Kessler’s suturing and Bunnell’s suturing were used for the 2nd ,3rd and 4th claws on the experimental side and in group B,Kleinert’s suturing ,Tsuge’s suturing and Ikuta’s suturing were employed for the 2nd ,3 rd and 4th claws on the experimental side .Each time ,10 animals were killed on 0， 3rd ,7th ,14th 21st, 28th ,42nd day after operation .The tendons of the profound flexor were harvested and subject to the mechanical strength test.Results The initial strength and strength 6 weeks after healing were much lower than those of normal tedon.Pmax rose constantly with the Tsuge’s suturing ,which reached the highest value 42days after operation.Although the Pmax with modified Kessler’s suturing technique was a little lower than that with the Tsuge’s suturing ,the value increased steadily.Conclusion Tsuge’s and modified Kessler’s suturing are the best techniques for tendon repair更多还原
