Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.
Combine shown in fig. 1, an auxiliary extension locking coaptation board of shin bone near-end, head 1, neck 2 and strip portion 3 including integrated into one piece, the locking coaptation board is 7 types, neck 2 is close to shin bone side surface for inside sunken and shin bone near-end radian to the interior concave surface that matches, follows 1 transverse direction evenly distributed of head has 4 first locking screw holes 101, the front end is provided with three gram formula pinhole 102 between the first locking screw hole 101, the neck is provided with second locking screw hole 201 and third locking screw hole 202, follows 3 axial directions of strip portion are provided with rectangular shape through-hole 301, 3 tail ends of strip portion are provided with 3 at least splayed through-holes 302.
In this embodiment, the distal end of the tibia can be locked by the splayed through hole 302 at the distal end for further stability by temporarily locking and positioning the kirschner pin hole 102 and then locking the proximal end by the first locking screw hole 101. Meanwhile, cortical bone screws are implanted in the elongated through holes 301.
Preferably, the aperture of the first locking screw hole 101 is 3.5 mm.
Preferably, a limited contact groove 303 is formed on one side of the strip-shaped part 3 close to the surface of the tibia along two sides of the strip-shaped through hole 301 and the splayed through hole 302.
In the technical scheme, the limited contact groove 303 can ensure that the bone fracture plate is attached to the bone surface and the normal operation of bone blood is ensured.
Preferably, the splayed through holes 302 are arranged in a straight line along the axial direction of the strip portion 3.
Preferably, the tail of the strip-shaped part 3 is further provided with a drawing hole 304.
In this embodiment, the traction hole 304 can perform traction correction on the tibial fracture.
Specifically, implant supplementary extension locking coaptation board in shin bone near-end outside, get patient's supine position, be connected steel sheet and external aiming at the frame, make a little incision at the shin bone near-end, put anatomical form shin bone near-end extension steel sheet into internal percutaneous, through the front and back position and the state of placing of side position image inspection steel sheet under C arm to confirm the osteotomy region.
