摘要
目的 研究 d区屈肌腱在单纯切割伤和严重挫伤下双腱修复后腱鞘不同处理的效果。 方法 将4 8只来亨鸡随机分为 4组 ,以鸡双足中趾 d区为手术对象 ,每组均行双腱修复。 A组 :单纯切割伤 ,腱鞘关闭 ;B组 :单纯切割伤 ,腱鞘切除 ;C组 :严重挫伤 ,腱鞘关闭 ;D组 :严重挫伤 ,腱鞘切除。肌腱修复后 6、12周末 ,分别进行生物力学评定和形态学评定。 结果 术后第 6、12周末 , d亚区内屈肌腱单纯切割伤双腱修复后 ,腱鞘关闭与腱鞘切除效果相当 ,肌腱的滑动距离、屈曲功能及粘连的表面积比较无统计学意义 (P>0 .0 5 ) ;而严重挫伤双腱修复后 ,腱鞘切除组肌腱滑动功能明显优于腱鞘关闭组 ,腱鞘切除组粘连的表面积显著小于腱鞘关闭组 ,有统计学意义 (P<0 .0 5 )。 结论 修复手外伤时 , d亚区内肌腱单纯切割伤双腱修复后腱鞘可关闭 ,而在严重挫伤双腱修复后 。
Objective To evaluate the management of sheath after repair of double tendons in clean-cut injury or severe injury in zone Ⅱd. Methods Forty-eight white leghorn chickens were divided into 4 groups. Both FDS and FDP tendons in zone Ⅱd of long toes were repaired with modified Kessler suture after tendon transection in group A(clean-cut tendon injury, sheath closure), group B( clean-cut tendon injury, sheath excision), group C (severe tendon injury, sheath closure) and group D (severe tendon injury, sheath excision), respectively. Biomechanical studies of gliding excursion and work of flexion were carried out 6 weeks and 12 weeks after tendon repair. The extent of adhesion was examined. Results After 6 and 12 weeks of repair, there were no significant differences in tendon excursion and work of flexion of the toes between groups A and B. Excursions of FDP tendons in group D was significantly larger than that in group C( P< 0.05). Work of flexion and extent of adhesion in group D was significantly less than that in group C( P< 0.05). Conclusion The above results indicate that sheath can be closed after repair of both FDS and FDP tendons in clean-cut injury and that sheath should be excised in severe injury in zone Ⅱd.
