单切口交锁髓内钉治疗漂浮膝

Treatment of floating knee injuries with interlocked intramedullary nailing through a single incision

目的:探讨单切口交锁髓内钉治疗漂浮膝的方法和临床效果。方法:38例创伤性漂浮膝患者,男25例,女13例;年龄17～52岁,平均35.6岁。采用膝部单切口股骨逆行及胫骨顺行交锁髓内钉固定治疗。对术后并发症、骨折愈合情况以及患肢的功能进行临床疗效评估。结果:全部患者伤口I期愈合,38例获随访8.6～15.4个月,平均12个月。37例获骨性愈合,骨折愈合时间2.7～6.9个月,平均4.8个月;1例股骨远端骨折逆行钉出现骨不连,经二次植骨钢板固定后,获骨性愈合。根据骨折愈合及关节功能等进行评价:优22例,良13例,可2例,差1例。结论:单切口交锁髓内钉治疗漂浮膝具有损伤小、感染率低、骨折愈合率高等优点,是一种有效的治疗漂浮膝方法。

Objective：To investigate the technique and clinical effect of interlocked intramedullary nailing through a single incision on the treatment of floating knee injuries. Methods：Thirty-eight patients of floating knee injuries included 25 male and 13 female with an average age of 35.5 years ranging from 17 to 52 years. All patients were treated by interlocked intramedullary nailing through a single incision. The clinical effect was evaluated postoperatively. Results：Thirty-eight cases were followed-up for 8.6 to 15.4 months with an average of 12.0 months. Thirty-seven cases gained bone healing and the time of fracture healing was from 2.7 to 6.9 months ,with an average of 4.8 months. The nonunion of the distal femoral fracture was ob- served in 1 case with retrograde nailing, the revision operation was performed by plate and bone graft ,and bony union was obtained. The results were excellent in 22 cases, good in 13 cases,fair in 2 cases,and poor in 1 case. Conclusion：The treatment of floating knee injuries with interlocked intramedullary nailing through a single incision brings less damage, low infection rate, good fracture healing. It is an effective method for treating floating knee injuries.
