Design Features
- Minimally Invasive Percutaneous Design: Designed for small-incision posterior fixation to reduce surgical exposure and support efficient postoperative recovery.
- Dual-Lead Thread: Dual-thread structure supports stable and controlled screw insertion.
- Non-Self-Tapping Design: Designed for use with dedicated preparation instruments during minimally invasive spinal fixation procedures.
- Anti-Loosening Fixation: Cement augmentation support helps improve fixation strength in osteoporotic bone and reduce loosening risk.
- Mechanical Stability: The bent rod fits tightly with the screw head to support stable force transmission.
- Breakaway Nut Locking: Dedicated locking nut design supports final fixation and system stability.
Clinical Applications
- Thoracolumbar osteoporotic fractures
- Degenerative spinal conditions
- Spinal stenosis
- Spinal tumors
- Implant failure revision
- Revision instability
Core Advantages
- Minimal Bleeding, Fast Recovery: Minimally invasive percutaneous approach with small incision design.
- Anti-Loosening Support: Cement augmentation provides additional fixation support in osteoporotic bone.
- Fluoroscopy-Guided Control: Designed for controlled screw placement under imaging guidance.
