单切口交锁髓内钉固定治疗创伤性浮膝

目的:探讨单切口交锁髓内钉固定治疗创伤性浮膝的疗效。方法:回顾1996年1月～2000年4月期间16例用交锁髓内钉治疗浮膝损伤的临床资料。手术采用膝关节正中单一切口,用股骨逆行交锁髓内钉和胫骨小径非扩髓交锁髓内钉固定。损伤程度评分平均为18.2分。术后平均随访3.4年(1.8～5.4年)。疗效评定采用Karlstrom和Olerud标准。结果:优良率为93.8％。胫骨骨折延迟愈合2例,感染1例。结论:单切口交锁髓内钉固定结合术后CPM功能锻炼治疗浮膝损伤,有良好的预后。

Treatment of Floating Knee Injuries with Interlocked Intramedullary Nailing through a Single Approach

Objective: to investigate the efficacy of interlocked intramedullary nailing through a single approach for floating knee injuries. Methods:Sixteen patients treated by interlocked intramedullary nailing fixation between 1996 and 2000 were reviewed. All patients were treated with a retrograde femoral intramedullary nail and a small diameter tibial intramedullary nail through a 7-cm middle incision. The average Injury Severity Score was 18.2 The mean follow-up time were 3.4 years(1. 8~5. 4 years). The outcome was assessed according to the criteria of Karlstrom and Olerud. Results: 93.8 % excellent and good results were obtained. Three patients required multiple surgeries because of two delayed unions and one case of chronic osteomyelitis. Conclusions: Interlocked intramedutlary nailing through a single incision combined with postoperative continuous passive motion (CPM) provides an efficacious approach to the treatment of patients with floating knee injuries.
