有关“漂浮膝”的几个问题(附7例报告)

Problems of Floating Knee

为探讨“漂浮膝”的概念、损伤特征和治疗方法等，作者总结７例“漂浮膝”，６例急诊手术，１例延期手术，其中３例同时行股骨和胫骨内固定。肢体功能随访结果：优５例，良１例，中１例。认为“漂浮膝”应是同侧股骨干和胫骨干或相邻的干骺端骨折而致整段膝关节漂浮，使膝关节呈连枷状。主张二处骨折同时手术内固定，不能同期内固定的。

To investigate the concept of floating knee, injury characteristic and therapies, the authors reviewed 6 cases of floating knee treated by emergency operation and 1 treated by delayed operation, of these 3 femoral fracture and tibia fracture were fixed internally simultaneously. At the last followup survey of limb function, 5 cases were excellent, 1 good and 1 fair. The concept of floating knee is considered the result of the whole knee joint floating, which is caused by the fracture of the ipsilateral femur and tibia to the proximal metaphysis, so the knee joint exhibits the model of flail. The authors suggest to have two fractures internally fixed simultaneously, if this can't be performed in the same operation, fixation should be done at one fracture at least.
