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.
目的 比較一種新型肌腱週邊縫閤方法與改良Kessler併連續週邊縫閤法在肌腱愈閤不同階段的生物力學特點,從而為該方法的臨床應用提供有關的動物實驗依據. 方法 在成年三黃鷄雙足第3趾Ⅱ區建立趾深屈肌腱橫斷模型,分彆應用新型肌腱縫閤方法(A組)、改良Kessler併連續週邊縫閤法(B組)脩複,于術後立即、術後2週、4週,分批處死動物,穫取標本,進行生物力學檢查. 結果 切割髮生率,A組<B組(P<0.05);手術操作時間,A組與B組無明顯差彆(P>0.05);生物力學測試結果:A組在肌腱愈閤的各階段,2mm間隙形成負荷及最大抗拉彊度優于B組 (P<0.05). 結論 該新型肌腱週邊縫閤法的生物力學彊度高于目前臨床應用的改良Kessler併連續週邊縫閤法,能提供較大的抗張彊度,有效牴禦間隙形成,操作簡便,有利于肌腱早期主被動功能鍛煉.

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 3Ⅱtoe area. Using new methods of tendon suture (group A), modified Kessler suture with continuous peripheral su-ture (Group B) to repair them respectively. The animals were sacrificed to obtain samples and undergo the biomechanical examination im-mediately 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 oOperation time of the two groups had:no significant difference (P>0.05)between group A and group B. Results of biome-chanical 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.
