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

[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

Restorative treatment of rupture of extensor tendon / 中国矫形外科杂志

The extensor tendon rupture is a common disease.Traditional management includes "8" suture and cross suture.But second operation is commonly needed for the reason of postoperative Nodules or adhesion.So a new technique is invented by the author:micro-weave suture combined with sodium hyaluronate.The new technique has improved dynamic intensity of the tendon and avoided postoperative adhesion.In this paper,this technique is reviewed.

Tendon Transfer for Radial Nerve Paralysis and Multiple Extensors Rupture / 대한정형외과학회잡지

Loss of radial nerve function in the hand results in a significant disability and so cannot extend the wrist, thumb & fingers according to the injury levels. Therefore the patient has great difficulty in grasping objects, especially power grip. Tendon transfers to restore function of extension of wrist and fingers are among the the best − most predictable transfers in the upper extremity. We performed 13 cases of tendon transfers for radial nerve palsy and extensive extensor ruptures from 1987 to 1993. The results were evaluated according to Arbitrary Value Method. Among 13 cases 30% of excellent, 46% of good, 24% of fair and no poor result were obtained and the better results were obtatined in low radial nerve lesion.

Experimental study and clinical application of anti-adhesion treatment and high-strength suture technique on the treatment of extensor tendon rupture / 解放军医学杂志

Objective To investigate the effects of anti-adhesion treatment and high-strength suture technique on the treatment of extensor tendon rupture by animal experiments and clinical application.Methods Twenty-eight leg-born chickens were randomly divided into four groups(7 each).Double cross suture was applied in group A,while double cross suture combined with sodium hyaluronate spraying in group B,cross-finger-like micro-braided suture in group C,and cross-finger-like micro-braided suture combined with sodium hyaluronate spraying in group D.The animals were sacrificed 6 weeks after operation,morphological,histological and biomechanics were observed and compared among the groups.One hundred and sixteen patients were treated with the surgical method in group D(89 males,27 females,aged 20-55 with an average of 36 years;73 with extensor tendon rupture,38 with strain/chalasis,5 with firearm injuries;56 on back of hand,48 on central slip,12 on lateral fixing chorda;82 with one-stage operation,and 34 with second-stage operation),and then followed-up for 2-5 years to observe the therapeutic effects.Results The repaired tendons in group D was in good contour,most tendon cells arranged regularly in bunches.The maximum load was significantly higher in group D(70.9?5.7N) than in group A(48.4?5.7N),Group B(51.3?3.2N) and Group C(68.3?2.8N,P
