ABSTRACT:
An external fixation device for the reduction of severely compounded or infected long bone fractures with substantial soft tissue involvement comprises at least two sets of retaining pins, each set including at least one retaining pin adapted to secure the bone portion distally or proximally of the fracture, a frame having a center section disposed between spaced end sections, and a pair of coupling elements mounted to the end sections of the frame each connecting one set of retaining pins to the frame. One of the coupling elements is adapted to move longitudinally, parallel to the longitudinal axis of the frame so as to properly position and secure one set of retaining pins and the bone portion connected thereto. The other coupling element is connected to a second set of retaining pins and is adapted to translate and pivot such pins, and the bone portion attached thereto, about three mutually orthogonal axes independently of the first coupling element. The frame and coupling elements of the fixation device are preassembled to simplify installation of the device during a surgical precedure and to facilitate post-operative distraction or compression of the fracture site.
