This study evaluated the biomechanical performance of a novel asymmetric 6-strand flexor tendon repair technique without locking loops.
Twenty porcine flexor tendons were equally repaired by using the asymmetric technique and compared with the modified Lim-Tsai repair technique. The ultimate tensile strength, load to 1-mm gap force, stiffness, and mechanism of failure were measured.
The asymmetric repair technique had significantly higher tensile strength (63.3 ± 3.7 N) than the modified Lim-Tsai repairs (46.7 ± 8.3 N).
A novel flexor tendon repair technique with improved biomechanical performance may be available for use in flexor tendon repairs.
本研究评估了一种新型无锁定环的不对称6股屈肌腱修复技术的生物力学性能。
采用不对称技术对20条猪屈肌腱进行同等修复,并与改良的Lim-Tsai修复技术进行比较。测量极限抗拉强度、1毫米间隙力时的负荷、刚度和失效机制。
不对称修复技术的抗拉强度(63.3±3.7牛)显著高于改良的Lim-Tsai修复技术(46.7±8.3牛)。
一种具有改善生物力学性能的新型屈肌腱修复技术可能可用于屈肌腱修复。
