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

The Effects of Core Suture Purchase on the Biomechanical Characteristics of a Multistrand Locking Flexor Tendon Repair: A Cadaveric Study

“…29 Multiple factors contribute to WOF, including bulk of tendon repair, adhesions of the tendons within the pulley system, joint stiffness, inertia of the distal part being moved, and the mechanical moment arm of the tendon across the joint. 20 The CLC-IHM repair with 3-0 FiberWire displays its highest 2-mm gap force (90 N), highest ultimate load to failure (111 N), and lowest increase in WOF (5%) at a suture purchase of 10 mm. The decrease in WOF with increasing suture purchase might be a result of decreased suture material at the repair site.…”

Factors That Influence the Outcome of Zone I and Zone II Flexor Tendon Repairs in Children

“…When dealing with zone II injuries, however, it has been proven in multiple studies in adults that the strength of the repair depends on the diameter and the number of sutures crossing the repair site and on the circumferential epitendinous repair. 22,23 In addition, starting early passive or active-assisted passive range-of-motion exercises after flexor tendon repair has been proven to prevent adhesion formation in the fibroosseous tendinous tunnel and to promote tendon healing. [1][2][3][4][5] Although it is possible to place more than one core suture in an adult-size tendon, this might not always be possible in the smaller pediatric-size tendon.…”

Work of Flexion Related to Different Suture Materials After Flexor Digitorum Profundus and Flexor Digitorum Superficialis Tendon Repair in Zone II: A Biomechanical Study

“…9 Increasing suture caliber also increases the work of flexion. 10 Differing suture techniques also alter the work of flexion. 11 With the recent introduction of FiberWire suture (Arthrex, Naples, FL), which is made from long-chain polyethylene with a braided polyester jacket, there exists the opportunity to create stronger repairs with smaller sutures, thereby decreasing work of flexion without sacrificing repair strength.…”
