The fatigue strength of three peripheral suture techniques for flexor tendon repair was compared by cyclic loading of repairs in a cotton dental roll tendon model. Thirty pairs of dental roll were sutured using only peripheral sutures with 6-0 polypropylene. An initial cyclic load of 5 N for 500 cycles was applied and increased by 5 N for an additional 500 cycles at each new load until rupture. The fatigue strength of an interlocking cross-stitch suture was 113% greater than a running suture and 36% greater than a standard cross-stitch suture. Interlocking the cross-stitch prevented shortening of the transverse portions under load and appears to be a useful technique for increasing the strength of the peripheral suture.
通过在棉制牙卷肌腱模型中对屈肌腱修复进行循环加载，比较了三种用于屈肌腱修复的周边缝合技术的疲劳强度。使用6-0聚丙烯仅进行周边缝合，将30对牙卷进行缝合。施加5 N的初始循环载荷500次循环，并在每次新载荷下再增加5 N并额外进行500次循环，直至断裂。锁扣式十字缝合法的疲劳强度比连续缝合法高113%，比标准十字缝合法高36%。锁扣式十字缝合法可防止横向部分在载荷下缩短，似乎是一种增加周边缝合强度的有用技术。
