The Pedicle 4.5mm Double Thread Monoaxial Screw is an advanced spinal implant used in posterior spinal fixation systems for stabilizing the thoracic and lumbar spine. It is designed to be inserted into the pedicle of vertebrae and connected with rods to achieve rigid spinal stabilization.
The double-thread design improves bone purchase by enhancing grip strength in cortical and cancellous bone, providing superior fixation and reducing the risk of screw loosening. This makes it especially effective in osteoporotic bone and complex spinal conditions.
As a monoaxial screw, the head is fixed and allows precise alignment with connecting rods, ensuring strong and controlled spinal construct assembly. This rigidity enhances correction accuracy in spinal deformities and trauma stabilization.
Manufactured from premium medical-grade titanium or stainless steel (depending on configuration), the implant offers excellent biocompatibility, corrosion resistance, and long-term mechanical durability. Precision machining ensures accurate insertion and secure rod engagement.
This pedicle screw is widely used in spinal trauma surgery, scoliosis correction, degenerative spine disease treatment, and veterinary spinal fixation procedures in large animals.
The system is fully sterilizable and supplied in sterile surgical packaging for safe handling and operating room efficiency.
