A novel interlocking intramedullary rod assembly which allows the surgeon to (i) secure a first bone fragment of a fractured bone (e.g., a distal bone fragment) to the interlocking intramedullary rod assembly in a fixed position, (ii) secure a second bone fragment of the fractured bone (e.g., a proximal bone fragment) to the interlocking intramedullary rod assembly in an adjustable manner, and (iii) thereafter selectively pivot the second bone fragment (e.g., the proximal bone fragment) relative to the first bone fragment (e.g., the distal bone fragment) so as to secure the two bone fragments in position relative to one another with the desired orientation.

The invention relates to a postoperative fixation device used for tibial fracture. The postoperative fixation device comprises a fixation board. Multiple toothed wheels are distributed along the length direction of the fixation board and provided with threaded rods which coaxially slide with the toothed wheels. The threaded rods are in threaded connection with the fixation board. Multiple vertical sliding grooves, corresponding to the toothed wheels one by one, are arranged in the fixation board. The vertical sliding grooves are internally provided with sliding blocks and springs disposed above the sliding blocks. The lower ends of the sliding blocks are hinged onto pressing semi-rings through ball bodies. The sliding blocks are equipped with press rods. The lower parts of the press rods are in threaded connection with the sliding blocks. The sliding blocks are provided with rotating disks capable of horizontally rotating. The rotating disks and the press rods are coaxially arranged. The rotating disks are vertically and slidably connected to upper parts of the press rods. The sliding blocks are equipped with torsion springs disposed above the rotating disks. Two ends of each torsion spring are connected to a sliding block and a rotating disk. Push rods, disposed above the rotating disks and capable of sliding, are arranged on the sliding blocks. The front ends of the push rods contact the threaded rods. The push rods are provided with guide rods. The rotating disks are equipped with spiral through grooves, in which guide rods are arranged. A toothed rack capable of sliding is arranged on the fixation board and can be meshed with the toothed wheels.
