Experimental study of the injury of extended tendon through cross-finger micro-weave sutue plus sodium hyaluronate to prevent adhesion / 中国矫形外科杂志

ABSTRACT

[Objective]To observe the effect of cross-finger-like micro-weave suture plus sodium hyaluronate technology in the treatment of extensor tendon injury by the animal experiments.[Method]Twenty-eight Leghorn chickens were randomly divided into four groups,double-cross stitching was used in group A in the treatment of extensor tendon injury,double-cross stitching plus sodium hyaluronate in group B,cross-finger-like micro-braided suture in group C,cross-finger-like micro-braided suture plug sodium hyaluronate surgery in group D.Six weeks after surgery,morphological observation,histological observation and biomechanical determination were done by using the naked eye and microscope,as well as the results of the experiments were statistically analyzed.[Result]In the group of the cross-finger-like micro-weave suture plus sodium hyaluronate,tendon grew in good shape without nodules after surgery,pseudome was formed around tendon,tendon cells mostly arranged regularly in bunches,maximum load was (70.9 ? 5.68) N on average,it was significantly larger than those in other groups and there was a significant difference by the analysis of variance (P
