Size: The screw appears to be 6.5mm in diameter, making it a relatively large screw suitable for use in larger bones.
Material: The screw appears to be made of titanium, a common material used in orthopedic implants due to its strength and biocompatibility. The blue color is likely due to a coating or treatment applied to the screw.
Shape: The screw has a cylindrical body with a sharp tip for easy insertion into bone. It also features a distinct head with a flat top, which likely has a slot for a screwdriver or a specialized tool for tightening the screw.
Thread: The screw has a threaded shaft, which helps to secure it in place within the bone and provides a strong mechanical hold. Pedicle screws have a specific thread design to engage with the dense cortical bone of the vertebral pedicle.
Rod Connection: The most distinctive feature of this screw is the rod connection at the head. This allows the screw to be used in conjunction with a spinal rod system, providing stability and support to the spine.
