摘要
目的 :分析和比较 4种肌腱缝合方法的生物力学特性 ,为临床提供实验基础。方法 :将新鲜成年猪后足 2 0只 ,随机分成 4组 ,解剖暴露中间二趾深屈肌腱后 ,第 1组行改良Kessler法缝合 ,第 2组行真皮嵌入法缝合 ,第 3组行Becker法缝合 ,第 4组行Tang法缝合。测定每组缝合方法的间隙形成负荷、2mm间隙形成负荷、最大负荷、最大功耗及弹性模量 ,并行统计学分析 (ANOVA)。结果 :Tang法的 2mm间隙形成负荷显著高于其他 3组 (P <0 .0 5 ) ,弹性模量最小。真皮嵌入法和Becker法的最大负荷、最大功耗较大。结论 :Tang法具有不易形成间隙、抗张力强和操作较为方便的优点 ,能够用于肌腱断端缝合对抗主动活动张力。
Objective:To compare the biomechanical character of four flexor tendon repair methods and provide experimental data for clinic.Methods:Forty flexor profoundus tendons harvested from 20 fresh pig posterior feet were divided into 4 groups.After these tendons transected,following techniquse were applied to repair the tendons: modified Kessler,internal dermal splint,Becker and Tang's methods.The load of gap formation,Load at 2 mm gap formation,maximum load,maximum engergy and Young's modulus were collected and calculated.Results:The tensile strength at gap formation and 2 mm gap formation in Tang's method group was significantly higher than those of other groups (P<0.05),and the group had the lowest Young's modulus.Conclusion:Tang's technique is an efficient and effective tendon repair technique.
