Abstract

The tensile strength of three different flexor tendon repair techniques were tested in vitro: the modified Kessler technique (a two-strand repair), two 'figure of eight' sutures (a four-strand repair) and three 'figure of eight' sutures (a six-strand repair). The mean breaking forces for the three techniques were 48.0 N, 73.1 N and 93.3 N, respectively, and the differences were highly significant (p < 0.0001). In a prospective clinical study, a total of 45 patients (50 fingers) with clean-cut complete lacerations of both flexor tendons in zone 2 were included. The protocol used the three 'figure of eight' suture techniques for (profundus only) tendon repair, 'venting' of the pulleys, and post-operative immediate active range of motion that ensured full active extension of the proximal interphalangeal joint. One repair (2%) ruptured. In the remaining 49 repairs, the result was considered excellent in 39 (78%) and good in 10 (20%) using the Strickland and Glogovac grading system.
