Prof. Zhang invented the bidirectional-traction reduction device, which is primarily composed of a reduction scaffold, traction bow, traction pin, connecting rod, auxiliary reduction device (bilateral frame and Schantz pin or Kirschner wire) and proximal connecting device (Figure 1).
This device can help reduce the fractures of four extremities (Figure 2).
Taking proximal tibial fracture for example, the surgical technique was introduced briefly as follows.
The patient was placed in a supine position. A Kirschner wire of 3-mm in diameter was drilled into the distal part of the femoral condyle and was connected to the proximal connecting device via a traction bow. A Kirschner wire of 2.5-mm in diameter was drilled into the distal tibia and was connected to the reduction scaffold also via a traction bow. A connecting rod of the proper length was selected to connect both proximal and distal parts as a whole (Figure 3).
The scaffold maintained the traction position during the operation, and its four legs were adjustable...
