Double Thread Polyaxial Screw 5.5 mm Spine System – Pedicle Screw, Rod & Clamp – 15 pcs

Description

The 5.5 mm Double Thread Polyaxial Pedicle Screw Spine System is engineered to deliver maximum versatility and stability in posterior spinal fixation procedures. Designed for use in thoracolumbar stabilization, this system integrates high-performance polyaxial screws with a durable rod and clamp configuration. The double-thread screw geometry enhances bone purchase, improves pullout resistance, and provides secure fixation in both normal and osteoporotic bone. The polyaxial head design allows multi-directional angulation, enabling surgeons to achieve precise rod alignment and optimal construct assembly even in complex deformity or trauma cases. The complete 15-piece set ensures intraoperative efficiency and dependable biomechanical support.
