Repair of tendon injury and prevention of adhesion / 中国组织工程研究

ABSTRACT

Tendon healing following injury includes two forms, endogenous healing and exogenous healing. The ideal way ofpreventing adhesion of tendon is to improve the nutritional state and the surrounding environment of tendon so as to promote endogenous healing and restrain/ease exogenous healing. The normally-used method for preventing the adhesion includessystemic or partial administration, protection and repair of tendinous sheath, substitution of tendinous sheath with autologous tissue or synthetic material, tendon transplantation, tendinous sheath reconstruction and so on, all of which do have some curative effects. However, recent research focus has come down to the degradable and absorbable polymeric biomaterials that can be used as barriers for preventing the adhesion. Besides, traditional Chinese medicine, rehabilitation therapy and early protected motion all can prevent the adhesion to some degree. In future, the tissue engineering tendon transplantation may become an investigative aspect. By using atreumatic technique and non-strangulated suture in the earlier period after tendon injury, warding and repairing tendinous sheath as much as possible as well as packaging the tendon with polymeric biomaterials during operation, and adopting combined therapy of rehabilitation therapy together with early protected motion after operation, we can prevent tendon adhesion obviously and have the gliding function of tendon recovered to the greatest extent.
