Abstract

The invention discloses an internal fixation device for anterior treatment of the thoracolumbar spine. The device is applied to a section of the thoracolumbar spine with a lesion, and the two axial end faces of the internal fixation device abut against the convex edges of the two ends of a vertebral body; the device comprises two parallel fixing plates, a connecting plate which is arranged betweenthe two fixing plates and used for connecting the middles of the two fixing plates, a stacking part of a first connecting part and a second connecting part and a locking part used for locking the first connecting part and the second connecting part; the inner side of each fixing plate has a radian matched with the physiological curvature of the vertebral body, and the fixing plates are provided with fixing holes for screws to penetrate through; the connecting plate is of a split structure and comprises the first connecting part and the second connecting part, wherein one end of the first connecting part is stacked with one end of the second connecting part; the locking part is made of degradable materials. The device is suitable for the treatment of compression fractures, the height of the lesion vertebral body can be kept, and the biomechanical properties of the vertebral body are restored.

Description

technical field [0001] The invention relates to the technical field of orthopedic medical devices, in particular to an internal fixation device for anterior thoracolumbar treatment. Background technique [0002] Surgical treatment of thoracolumbar fractures, degeneration, and deformity correction has been widely adopted by the orthopedic community. Anterior plate fixation has become a clinical focus in recent years because of its remarkable clinical features. [0003] Among them, compression fractures are mainly caused by the sudden excessive flexion of the spine caused by the transmission of violence from the direction of the head and feet. Due to the injury of the flexion position of the spine, the external force is concentrated on the front of one vertebral body, and at the same time it is squeezed by the upper and lower vertebral bodies. , so the vertebral body is compressed and wedge-shaped, and shifted backward, damaging the spinal cord or cauda equina. If it affects ...
