Abstract

The invention provides a spine fixing system, which belongs to orthopaedic implants and comprises a spine bone plate and screws. The screws are matched with screw holes of the bone plate and used forfixing the bone plate. When the spine fixing system is used, the screws penetrate through the screw holes to fix the bone plate to the bone. Meanwhile, the depth of the threads is increased, the surface structure of the threads is improved, and therefore the holding force and the anti-pull-out force of the screws are increased, it is guaranteed that the screws are stable for a long time, a good effect is achieved, and bone healing is facilitated.

Description

technical field [0001] The present invention relates to an orthopedic implant, in particular to a fixation system for stabilizing the spine. Background technique [0002] The human spine will be damaged due to illness or external force, such as vertebral body tumors, severe comminuted fractures, and infectious diseases such as tuberculosis, which may lead to spinal cord and nerve damage or collapse of vertebral segments and angular deformity of the spine. Causes various injuries to the spine of the human body. Spinal fractures are very common, accounting for about 5%-6% of systemic fractures. The main symptoms of spinal fracture or dislocation are local pain, difficulty in standing and turning over. Retroperitoneal hematoma irritates the celiac ganglion, which slows down intestinal peristalsis. Abdominal pain, abdominal distension and even intestinal paralysis often occur. Therefore, effective treatment of spinal fractures is of great significance. [0003] Fixation plate...
