Monoaxial Screw Single Lock 4.0mm

Description

Buy the Monoaxial Screw – Single Lock – 4.0mm, engineered for stable and accurate fixation in posterior spinal instrumentation, especially in cervical and upper thoracic constructs requiring smaller-diameter screws.

The monoaxial head offers a fixed-angle interface with the rod, allowing precise correction forces, controlled alignment, and enhanced stability during deformity correction, trauma fixation, or degenerative spine surgery.

The single-lock mechanism ensures a robust screw–rod connection while simplifying instrumentation. Its specialized dual-thread profile (cancellous + cortical) enhances:

• Pull-out strength

• Bone purchase

• Smooth insertion torque

• Long-term construct stability

Ideal for:

• Cervical and upper thoracic fixation

• Trauma and fracture stabilization

• Degenerative spine pathologies

• Small-segment fusion constructs

Manufactured from high-strength medical-grade materials for durability, biocompatibility, and optimal mechanical performance.

A reliable choice for spine surgeons, trauma hospitals, and implant suppliers looking to purchase 4.0mm monoaxial single-lock screws that offer strong fixation, precise control, and stable spinal reconstruction.
