Bilateral floating knees in a multiple injured patient. A case report.

Bilateral floating knees are rarely seen in orthopedic practice. Ipsilateral fractures of the femur and tibia are becoming more common due to an increase of high-velocity accidents. The following case presents a 23-year-old male motorcyclist who sustained multiple musculoskeletal injuries including a burst fracture of the elbow and fractures of both femurs and both tibiae. Early operative stabilization of all the fractures was performed. A comminuted fracture of the ulna was fixed with a Dynamic Compression Plate (DCP) and the fractures of both femurs and both tibiae were fixed with Enders nailing. Operative treatment produced excellent results without significant complications. As a result of this study it is concluded that Enders nailing of long bone fractures is a useful procedure in selected patients and can produce desirable results.
