Repair of Zone II Flexor Digitorum Profundus Lacerations Using Varying Suture Sizes: A Comparative Biomechanical Study

In this cadaveric study we found that increasing locking cruciate suture caliber from 4-0 to 2-0 increased maximum tensile strength but also caused increased work of flexion. Gapping was not affected by suture caliber. There was no significant difference in strength or mean change in work of flexion between 3-0 or 4-0 braided polyester sutures.
