微创手术治疗浮膝31例

31 cases of floating knees treated by minimally invasive surgery

目的 探讨微创手术方法治疗浮膝的临床意义。方法 对31例股骨中下段骨折合并同侧胫骨中上段骨折患者采用闭合复位股骨及胫骨交锁髓内钉内固定治疗。结果 31例随访8～20个月，仅1例出现胫骨延迟愈合，HSS膝关节功能评分优23例，良7例。结论 髓内钉对骨折的固定稳定牢靠，采取闭合复位的微创手术对骨折端的血循环影响较小，对于浮膝病例是其适应证。

Objective To＇investigate minimally invasive surgery （MIS） for floating knee. Methods 31 cases with middle and distal femoral fractures associated with ipsilateral tihial fractures were treated with closed reduction and femoral and tihial interlocking intramedullary nailing. Results All cases were followed up for 8 - 20 months. Only 1 was complicated with tihial delayed union. According to HSS system, the function recovery of knee was excellent in 23 cases and good in 7. Conclusions Intramedullary nailing can provide stable fracture fixation, and MIS with closed reduction compromises little vascular support, which is suitable for floating knee.
