Spinal trauma, spondylolisthesis, spinal infections, tumors and tuberculosis need to be reconstructed posteriorly after resection
Optimized breaking design, the breaking groove is a 45°V-shaped structure.
The diameter of the base and the tail wall is 14mm, the base is stronger, and will not be deformed or opened.
For poly-axial screws, the spherical ring is designed into a saddle shape, which can reduce deformation. The poly-axial screws and the central axis can be adjusted at 25 degrees, which is convenient for intraoperative adjustment. The diameter of the ball head of the poly-axial screw is increased, and the design of fine lines is added on the ball head to improve the friction
The root of the screw is a taper thread. From the starting point of the thread to the base, it is a tapered shape. From the starting point to the root, the inner diameter gradually increases. This makes the root strength of the pedicle screw stronger and avoids the screw break.
Compression nut thread negative angle design structure, the clearance fit accuracy is higher, the placement is safer and easier, and the risk of sliding teeth and spreading is also reduced.
