Abstract:
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
