摘要
目的 通过比较5 种肌腱缝合方法的生物力学特性,以指导临床工作。方法 将新鲜成年猪后足50 只,随机分成5 组,解剖暴露第二趾深屈肌肌腱后,并在Ⅱ区横断,第1 组行改良Kessler缝合,第2 组行津下缝合,第3 组行双改良Kessler 缝合,第4 组行津下加双改良Kessler 缝合,第5 组行汤氏缝合。用Instron 力学测定仪测定每组缝合方法的2 m m 间隙形成的负荷、最大负荷及功耗,并行统计学分析(ANOVA) 。结果 汤氏缝合法的2 m m 间隙形成的负荷、最大负荷及功耗最大,改良Kessler 及津下缝合法最小。汤氏缝合法与其他4 组相比较统计学差异有显著性意义( P< 0 .01) 。
Objective This study was designed to compare the special biomechanical features of five different suture techniques which were used clinically for tendon repair. Methods 50 flexor profundus tendons of the toes of the hindfeet of the pigs were randomly allocated into five groups. The tendons in each group were transected in zoneⅡ, and were repaired by the following five suture techniques: (1) Modified Kessler; (2) Tsuge; (3) Double Kessler; (4) Modified Kessler+Tsuge; (5) Tangs suture. Instron testing machine was used to test 2 mm gap formation force and failure load. Maximum work was also calculated for comparison between each group. Results Tangs suture technique has the greatest tensile strength with its 2mm gap force and failure load almost one fold larger than group 1 and 2, 0.5 time larger than group 3 and 4. The maximum work was also significanty greater than that of other four suture techniques( P< 0.01 or P< 0.001). Conclusion Tangs suture technique was recommended for the clinical repair of tendon in zone Ⅱbecause of its reliable tensile strength.
