Thirty-six superficial digital flexor tendons from nine fresh equine cadavers were transected and sutured with size 2 monofilament nylon. Nine tendons were repaired with each of four suture patterns: single-locking loop, double-locking loop, triple-locking loop, or three-loop pulley. The times required for application, tensile strengths, resistance to distraction (gap), and modes of failure were analyzed. The mean times required were: single-locking loop, 3 mins, 15 secs; double-locking loop, 4 mins, 15 secs; triple-locking loop, 10 mins, 50 secs; and three-loop pulley, 4 mins. The double-locking loop, triple-locking loop, and three-loop pulley suture patterns were stronger than the single-locking loop. The triple-locking loop and three-loop pulley patterns were close in strength and only the triple-locking loop was stronger than the double-locking loop. The three-loop pulley had the greatest resistance to gap formation and its mode of failure was different from the others. The three-locking loop suture patterns failed by suture breakage but the three-loop pulley failed first by suture pull-out and then by suture breakage.
取自九具新鲜马尸体的36条指浅屈肌腱被切断，并用2号单丝尼龙线缝合。九条肌腱分别采用四种缝合方式进行修复：单锁环、双锁环、三锁环或三环滑车。分析了应用所需时间、拉伸强度、抗牵张能力（间隙）和失效模式。所需平均时间分别为：单锁环3分15秒；双锁环4分15秒；三锁环10分50秒；三环滑车4分钟。双锁环、三锁环和三环滑车缝合方式比单锁环更强。三锁环和三环滑车模式在强度上相近，只有三锁环比双锁环更强。三环滑车对间隙形成的抵抗力最大，其失效模式与其他方式不同。三锁环缝合方式因缝线断裂而失效，但三环滑车首先因缝线拔出失效，然后才是缝线断裂。
