浮膝损伤的手术治疗

目的探讨浮膝损伤的手术治疗方法。方法采用交锁髓内针、单臂外固定支架、钢板及动力髁螺钉内固定，术后早期膝关节功能锻炼。结果69例随访1—4年，平均2．5年，4例胫骨骨不连，1例股骨骨不连及2例膝关节强直。结论浮膝损伤首先纠正休克及处理合并伤，而后根据不同分型采用内固定器械。交锁髓内针是治疗浮膝损伤有效方式，单臂外固定支架治疗骨折软组织损伤小，动力髁螺钉治疗股骨髁上骨折行之有效，钢板固定易发生骨不连接。早期膝关节功能锻炼可防止关节强直。

Operational treatment of floating knee injury patients

Objective To study the method of operative therapy for floating knee injury. Methods Internal fixation with interlocking intramedullary nail. single-hand extra-fixer steel plate and Dynamic Condylar Screw (DCS) were adopted. Functional exercise early after operation was practiced. Results Sixty-nine cases were followed up from 1 to 4 years. average 2.5 years. Nonunion of tibia were observed in four cases, nonunion of femur in one case and rigidity of knee joint in two cases. Conclusion The shock and the complications should be treated first, then internal-fixation machine be used. Internal fixation with interlocking intramedullary nail is a effective method, the injury of tissuses is little by using the single-hand extra-fixer. Treatment with Dynamic Condylar Screw for supracondyle of femur is effective, fixation with steel plate is liable to lead to nonunion. Functional exercising in early period can avoid the rigidity of joint.
