Polyaxial pedicle screw Z 6

- Used for Dislocation and fracture of spines. Optimized fracture design, won’t irritate the soft tissue. Flexible angle can be adjusted for intraoperative adjustment. Increased ball head’s diameter & surface texture improve the friction. Double-line variable pitch, enhance the resistance. Taper thread makes screw stronger and avoid break. Negative angle design structure, accuracy is higher, sliding teeth risk is lower. DIAMETER 4.5/5/5.5/6/6.5/7/7.5
