Randomized Controlled Trial Comparative Study
Work of flexion related to different suture materials after flexor digitorum profundus and flexor digitorum superficialis tendon repair in zone II: a biomechanical study.
Repair of both flexor digitorum profundus (FDP) and flexor digitorum superficialis (FDS) tendons is commonly performed in zone II flexor tendon injuries; however, the bulk of the repair may impair tendon gliding. We evaluated whether repairing 1 slip of FDS tendon and resecting the other would significantly decrease work of flexion and whether suture material affected this interaction in an in vitro study. ⋯ Resection of 1 slip of FDS tendon significantly reduces work of flexion in zone II flexor tendon repair. Suture material had no effect on this interaction.
