Special-shaped block at outer side of proximal tibia

Abstract

Embodiments of the invention relates to a proximal tibia outer side special-shaped block. The special-shaped block at the outer side of proximal tibia specifically comprises a first fixing part and asecond fixing part, wherein the first fixing part is connected with the second fixing part; the inner surface of the first fixing part is an arc-shaped surface; a first top locking screw hole, a second top locking screw hole, a third top locking screw hole and a fourth top locking screw hole are sequentially formed in the top of the first fixing part from the inner side to the outer side; a firstmiddle locking screw hole, a second middle locking screw hole and a third middle locking screw hole are sequentially formed in the middle part of the first fixing part from the inner side to the outerside; a first oblique-insertion locking screw hole is formed in the lower part of the first fixing part; and the second fixing part comprises fixing screw holes located in the surface of the second fixing part, a front side connecting screw hole formed in the front side position of the side surface of the second fixing part, and a rear side connecting screw hole formed in the rear side position of the side surface of the second fixing part.

Description

technical field [0001] The invention relates to the field of orthopedic medical instruments, in particular to a special-shaped block outside the proximal end of the tibia. Background technique [0002] The way to provide treatment and rehabilitation for fractures usually needs to be given appropriate treatment according to the bone structure of the injured part. When the fracture is close to the joint, it is not suitable to use plaster for fixation. Bone fixation plates and bone nails are usually used for fixation. Fractured instruments. [0003] The existing tibial fracture fixation method is to first indirectly reset the bone, and then use the bone fixation plate for indirect fixation, but this method is not effective in reduction or fixation, and the operation takes a long time; after the operation recovers, the fracture site It is easy to cause displacement due to insufficient fixation force; in addition, the traditional bone fixation plate needs to be completely attach...

AI Technical Summary

Problems solved by technology

[0003] The existing tibial fracture fixation method is to first indirectly reset the bone, and then use the bone fixation plate for indirect fixation, but this method is not effective in reduction or fixation, and the operation takes a long time; after the operation recovers, the fracture site It is easy to cause displacement due to insufficient fixation force; in addition, the traditional bone fixation plate needs to be completely attached to the bone, and relies on the friction between the bone plate and the bone to achieve the effect of fixation, but because this fixation method will lock the periosteum Causes poor blood transport at the fracture site, and also causes slow healing of the postoperative fracture site or other complications

Therefore, the postoperative recovery effect will also be poor.
