摘要
目的：通过实验寻找新的腱鞘修复材料。方法：２８ 只白兔分为２ 组，于右后肢２ 、３ 趾屈肌腱Ⅱ区切除腱鞘，造成肌腱损伤，对照组腱鞘不予修复，实验组用酒精保存的异体硬脊膜重建腱鞘，术后２ 、４ 、８ 、１２ 周行大体和光镜观察，８周时还行肌腱粘连等级和屈趾功能测定。结果：对照组腱周形成致密粘连；实验组新建腱鞘逐渐接近正常，腱周间隙明显，屈趾功能优于对照组（ Ｐ＜ ０ ．０１） 。结论：保存的同种异体硬脊膜可以作为重建腱鞘的材料。
Objective: To find a new material for epitenon repairing in experimental study.Methords:48 rabbits were divided into 2 groups.The flexor tendon epitenons were removed and the tendons were traumatized at 'no man's area' in second and third toes of right hind legs.The epitenons were unrepaired in control group and reconstructed with stored homologous dura mater in studied group.The specimens were observed grossly and histologically at 2、4、8 and 12 weeks postoperatively.The grades of adhesion and flexor function of injured tendon were also evaluated at 8 weeks.Results:In the studied group,the grafted dura mater turned into an epitenon-like tissue gradually.There was an abvious gap around the tendon.The flexor function of toes in this group was significantly superior to those in the control group(P<0.01).Severe peritendoneal adhesions were formed in control group.Conclusion:The stored allogeneic dura mater can be served as a new material for repairing epitenon.
