Abstract

The invention discloses a fixing device for neutralizing actions between two vertebral bodies, in particular a fixing device for neutralizing or countervailing actions between two adjacent vertebral bodies. The fixing device is a plate-shaped body, one side of the plate-shaped body is provided with a nail part, and the fixing device is embedded into two corresponding vertebral bodies and intervertebral discs by the nail part. When necessary, the fixing device also can be matched with a support assembly, such as a metal cage, and embedded into the intervertebral discs of the two corresponding vertebral bodies. Therefore, the fixing device can effectively control actions between the two vertebral bodies, such as forward bending, backward bending, left and right incline, left and right turn,and the like, and enable an autogenous bone embedded between the two adjacent vertebral bodies not to generate the problem of non-union or psuedarthrosis because of actions between the vertebral bodies before completely inosculated with the vertebral bodies.

Description

technical field

[0001] The present invention provides a fixation device for neutralizing the movement between two vertebral bodies, especially applied between the vertebral bodies of two adjacent thoracic vertebrae, lumbar vertebrae...etc. Activities between adjacent vertebrae, such as bending forward, leaning back, tilting left and right, and twisting left and right, will cause problems such as poor fusion of the two vertebrae. Background technique

[0002] Press, generally called "lumbar interbody fusion (interbody fusion)", which is mainly performed from the posterior (stripping the lumbar neural canal dura mater) or from the anterior (from the front of the abdomen to the front of the disc in the posterior abdominal cavity), First remove the degenerated intervertebral discs until there is no residual soft tissue between the two adjacent lumbar vertebrae, and then implant human bone (autologous or allogeneic) between the two adjacent lumbar vertebrae. After several months ...
