Abstract

The invention provides a spine fixing device, and belongs to an orthopaedic implant. The spine fixing device comprises a bone plate and screws. The screws and nail holes of the bone plate are used in cooperation for fixing the bone plate. When the bone fixing device is used, the screws penetrate through the nail holes to fix the bone plate to a bone, operation is easy, fixing is firm, and healing of the bone is facilitated.

Description

technical field [0001] The present invention relates to an orthopedic implant, in particular to a fixation device for stabilizing the spine. Background technique [0002] A wide variety of injuries can be inflicted on the human spine due to degeneration, tumors, and fractures and dislocations caused by physical trauma. Spinal fractures are very common, accounting for about 5%-6% of systemic fractures. Spinal fractures can be accompanied by spinal cord or cauda equina injury, especially cervical fractures and dislocations combined with spinal cord injury. It is reported that up to 70% of them can be seriously disabled or even lost their lives. 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...
