动态髌骨牵引固定器治疗陈旧髌腱断裂

Dynamic traction and fixing apparatus in repair of old rupture of patellar tendon

目的探讨陈旧髌腱断裂的修复方法。方法设计“井”形固定器,在动态条件下,将髌骨复位、股四头肌松懈、髌腱修补及术后带固定器活动。结果治疗6例,随访时间8～56个月,平均26个月,膝关节伸屈活动取得了满意的治疗效果。结论应用“井”形外固定器动态下,治疗陈旧性髌腱断裂,解决了髌腱、股四头肌挛缩,又有利于缝合修复后固定,还可早期练习膝关节功能。方法简单,是一种较为合理的新的治疗方法。

Objective To explore an effective method of repairing the old rupture of patellar tendon. Methods We designed a new 井-shaped apparatus for traction and fixing which was to be used, under the dynamic conditions, to reduce the patella, loosen the quadriceps m. of thigh, repair the tendon of knee cap and facilitate postoperative exercises with the fixing apparatus on. Results We used the apparatus to repair the tendon of knee cap in 6 cases. The follow up of 8 to 56 months (averaging 26 months) showed that their functions of the knee joint were all satisfactory. Conclusions The 井-shaped external fixation device can be used under the dynamic conditions to repair the old rupture of patellar tendon with the advantages of little contracture of the knee cap and quadriceps m. of thigh, easy fixation after repair and suture, and early exercise of the knee joint. This novel method is simple and recommendable.
