Polyaxial Screw (DT) – Dual Threaded Pedicle Screw for Spinal Fixation

The Polyaxial Screw (DT) is a dual-threaded pedicle screw engineered for posterior spinal fixation. Featuring polyaxial head mobility and dual-thread (DT) technology, it offers superior anchorage in both cortical and cancellous bone.

This screw enables flexible rod alignment through its 360° rotating head, allowing precise adaptation during multilevel spinal fusion procedures. The DT threading provides increased surface contact, reducing the risk of loosening and improving bone-screw interface, especially in osteoporotic or compromised bone structures.

Manufactured using high-grade titanium alloy (Ti-6Al-4V), it ensures biocompatibility, radiolucency under imaging, and long-term stability.
