可吸收钉联合强生PDS线张力带法治疗髌骨骨折

Treatment of patella fracture with absorbable screws and Johnson PDS suture tension band

目的探讨可吸收钉可吸收缝线张力带固定的生物力学性能及其在髌骨骨折治疗的临床应用效果。方法25例髌骨骨折采用可吸收钉及其强生PDS线张力带治疗。髌前下方横弧形切口,垂直骨折线骨实质内旋入2枚可吸收螺钉,通过髌骨上极骨实质的横孔引过强生PDS1号线髌前"8"字状交叉再经绕下极两枚可吸收钉钉尾收紧打结固定。结果术后3～12月,患者全部获得随访,平均随访期5月,骨折全部得到愈合,未发生骨折断端再移位,无膝关节功能不良。结论可吸收钉联合强生PDS线张力带法在治疗髌骨骨折中具有较好的生物力学性能和效果,能避免金属内固定物可能产生的诸多并发症,且无需二次取出。

Objective To explore the biomechanical characters and the clinical outcome of absorbable screws and absorbable suture tension band in the treatment of patella fractures. Methods 25cases with patellar fracture were fixed by biodegradable tension band. Results All patients were followed up, average was 5 months,（range,3-12 months） they were all cureed without fracture displacement and without dysfunction of knuckle. Conclusion absorbable screws and absorbable suture tension band has better biomechanical characters and it can avoid many complications caused by metal tension band fixation, and it did not need to remove and release the pain of patients.
