摘要
目的比较一种新型肌腱周边缝合方法与改良Kessler并连续周边缝合法在肌腱愈合不同阶段的生物力学特点,从而为该方法的临床应用提供有关的动物实验依据。方法在成年三黄鸡双足第3趾Ⅱ区建立趾深屈肌腱横断模型,分别应用新型肌腱缝合方法(A组)、改良Kessler并连续周边缝合法(B组)修复,于术后立即、术后2周、4周,分批处死动物,获取标本,进行生物力学检查。结果切割发生率,A组<B组(P<0.05);手术操作时间,A组与B组无明显差别(P>0.05);生物力学测试结果:A组在肌腱愈合的各阶段,2mm间隙形成负荷及最大抗拉强度优于B组(P<0.05)。结论该新型肌腱周边缝合法的生物力学强度高于目前临床应用的改良Kessler并连续周边缝合法,能提供较大的抗张强度,有效抵御间隙形成,操作简便,有利于肌腱早期主被动功能锻炼。
Objective To compare a new and improved method of tendon surrounding suture with the method of modified Kessler suture with continuous peripheral suture of biomechanics in different stage of tendon healing. In order to, and provide information on the basis of animal experiments for the clinical application of this method. Method Establishing toe deep flexor tendon transection model in adult three yellow feet 3 Ⅱ toe area. Using new methods of tendon suture（group A）, modified Kessler suture with continuous peripheral suture（Group B） to repair them respectively. The animals were sacrificed to obtain samples and undergo the biomechanical examination immediately after the operation and two, four weeks after operation. Results Incidence of cutting： in group A〈 was less than that in group B（P〈0.05）. The o Operation time of the two groups had ： no significant difference（P〉0.05）between group A and group B. Results of biomechanical test： group A in each tendon healing stage, 2mm gap forming load and maximum tensile strength in group A was better than that in group B（P〈0.05）. Conclusion Biomechanical strength of the new peripheral suture method of tendon is was better than the current clinical application of modified Kessler suture with continuous peripheral suture. The new method can could provide greater tensile strength and effectively resist the form of gap. It wasis easy to operate and conducive for tendon passive functional exercise at early stage.
