The Study Of The Acute Closed Rupture Of Achilles Tendon Using The Short Incision And Tenocutaneous Relaxing Suture

Partâ… The histology study in rabbit of the acute closed rupture of Achilles tendon using the short incision and tenocutaneous relaxing Suture.Objective To evaluate the histological feature of the short incision and tenocutaneous relaxing suture to treat the acute closed rupture of the Achilles tendon. Methods Using 48 rabbits ,one Achilles tendon of the two legs behind was established the animal model.24 rabbits ,as experimental group ,were treated with the short incision and tenocutaneous relaxing suture,and the others were treated with the Kesser suture.After having made specimen,macroscopic observation ,histological observation were performed at 1,3,4,8,10,14 weeks for evaluating,classification and analysis .Result Macroscopic and histology showed that the healing of the experimental group was better the control group ,and the adhesions was less than it .Conclusion The short incision and tenocutaneous relaxing suture has the advantages of better healing and less adhesions.Partâ…¡The biomechanical property study in rabbit of the acute closed rupture of Achilles tendon using the short incision and tenocutaneous relaxing Suture.Objective To evaluate the biomechanical property of the short incision and tenocutaneous relaxing suture to treat the acute closed rupture of the Achilles tendon. Methods 5 rabbits,as the as experimental group,were treated with the short incision and tenocutaneous relaxing suture,and the other 5 were treated with the Kesser suture.The biomechanical indices were tested after 14 weeks. Result The biomechanical property of the experimental group were closed to the normal group(P>0.05), and had the obvious difference with the control group (P<0.05) Conlution The short incision and tenocutaneous relaxing suture has the advantage in healing.Partâ…¢The clinical study of the the acute closed rupture of Achilles tendon using the short incision and tenocutaneous relaxing Suture.Objective To evaluate the long term effect of the short incision and tenocutaneous relaxing suture to treat the acute closed rupture of the Achilles tendon. Method 28 cases were treated by short incision and tenocutaneous relaxing suture from 1996-2007,The scar tissue and blood blocks between the ends of ruptured Achilles tendon were first debrided completely,then treated with percutanneous decmpression suture, the duration of follow up ranged from 2 years to 10 years.The treatment outcome were evaluated by Arner-lindholm evaluation system and the MRI of post operation. 2 cases were lost. Result According to the Arner-lindholm evaluation system and the MRI of post operation,the treatment outcome was excellent in 18,and good in 6,with excellent rate of 92%, No complication including nerve injury and infection were found after operation ,except 1 rerupture of Achilles tendon was found during the follow up period .The MRI showed the rupture Achilles tendon were repaired and remodeled very well in all cases. Conclusion The short incision and tenocutaneous relaxing suture is an ideal surgical technique ,with good clinical result and less significant complication .
