Estudo biomecânico in vitro das suturas em “oito” e de Kessler de tendões flexores de porcos

Abstract

Objective To evaluate the biomechanical properties of the “figure-of-eight” and Kessler suture techniques for tendons. Methods Flexor tendons of porcine fingers were divided into two groups with triple central “figure of eight” sutures (six passages) and Kessler sutures (two passages) associated with simple and continuous peripheral sutures, and submitted to continuous longitudinal mechanical tests, to obtain the mechanical properties of maximum load and energy at maximum load. Results The mean maximum load and energy at maximum load in the “figure-of-8” suture were of 63.4 N and 217.3 N.mm respectively; in the Kessler suture, the values were of 34.19 N and 100.9 N.mm respectively. The statistical analysis indicated that the “figure-of-eight” suture is mechanically superior to the Kessler technique. Conclusion Under the conditions of this experiment and in the flexor tendon of porcine fingers, the triple “figure-of-eight” suture (six passages) is more resistant than the Kessler suture (two passages). The “figure-of-eight” suture with six passages enables active movement in the immediate rehabilitation of the flexor tendon repair of the finger, with little risk of rupture or suture spacing.

Effects of evidence‐based nursing care interventions on wound pain and wound complications following surgery for finger tendon injury

“…With the increase in the proportion of hand trauma, finger tendon injury has become a common disease, which can be caused by various factors such as cuts, saw injuries and contusion 6–8 . Microsuture repair surgery is often used for finger tendon injuries, and the effect is good 9,10 . However, a long recovery time is required after the operation, and if effective nursing intervention is not received, a series of complications such as local swelling and pain, wound infection, tendon adhesion and limited hand movement may occur after the operation, which is not conducive to wound healing and patient recovery, and severe cases may lead to the risk of digit or limb amputation 11,12 .…”
