Monoaxial Dual Thread Screw 5.5mm

Description

The Monoaxial Dual Thread Screw 5.5mm is a premium, high-performance implant engineered for secure and highly stable fixation within posterior spinal instrumentation systems. This sophisticated pedicle screw features an advanced dual-thread design, combining differentiated cortical and cancellous thread profiles along the screw shaft. This precise geometry ensures optimal engagement in both dense cortical bone and softer cancellous bone, significantly enhancing bone purchase, reducing insertion resistance, and maximizing pull-out strength.

Designed with a rigid monoaxial head, this screw provides absolute, fixed-angle stability for direct screw-to-rod engagement. This rigidity is crucial for applying powerful corrective forces during complex spinal deformity corrections and ensuring uncompromising structural support in trauma and fusion constructs. Manufactured from high-strength, Medical-Grade Materials (typically Titanium Alloy), this implant delivers the long-term biomechanical stability and fatigue resistance required for successful spinal fusion and patient rehabilitation.

Key Features & Benefits

• Advanced Dual-Thread Profile: Integrates distinct thread pitches tailored for both cortical and cancellous bone, ensuring maximum grip and significantly improved pull-out strength.

• Rigid Monoaxial Head: Offers a fixed, solid connection to the longitudinal rod, allowing for precise vertebral alignment and the direct translation of corrective forces.

• Smooth Insertion Torque: The specialized thread geometry allows for controlled, efficient insertion with reduced physical exertion, minimizing stress on the surrounding bone.

• Strong Locking Interface: Engineered to provide a secure, anti-loosening connection with the set screw and rod, ensuring construct integrity over the long term.

• High Mechanical Strength: Manufactured from premium medical-grade alloys to withstand the extreme physiological loads of the human spine without fatiguing.

• Predictable Biomechanical Performance: Delivers consistent, reliable stabilization critical for achieving solid arthrodesis (bone fusion).

Primary Clinical Applications

• Spinal Deformity Correction: The monoaxial design provides the rigid leverage necessary for the derotation and realignment of vertebrae in scoliosis or kyphosis surgeries.

• Degenerative Spine Fixation: Essential for stabilizing vertebral segments affected by severe degenerative disc disease, spondylolisthesis, or spinal stenosis.

• Trauma Stabilization: Provides the immediate, robust immobilization required following high-energy spinal fractures or dislocations.

• Spinal Fusion Constructs: Acts as a reliable foundation for posterior lumbar, thoracic, or thoracolumbar fusion procedures.

• Rod-Based Stabilization Systems: Fully compatible with standard 5.5mm rod systems used in complex, multi-level spinal reconstructions.
