Nut (for Long-Tail Polyaxial Pedicle Screw)

Nut (for Long-Tail Polyaxial Pedicle Screw): What Is It?

• A specialized locking nut designed to secure rods to long-tail polyaxial pedicle screws in spinal fixation systems.
• Ensures rigid connection between rods and screws, maintaining spinal alignment during healing.

Applications of Nut (for Long-Tail Polyaxial Pedicle Screw)

1. Thoracolumbar Spinal Fusion
   • Locks rods to long-tail screws in TLIF/PLIF procedures → stabilizes fused vertebrae.
   • Supports load distribution across spinal segments → reduces screw loosening risk.
2. Spinal Deformity Correction
   • Secures rods in scoliosis/kyphosis correction → maintains corrected spinal curvature.
   • Withstands corrective tension → ensures long-term deformity control.
3. Traumatic Spinal Fractures
   • Reinforces rod-screw constructs in burst/compression fracture fixation.
   • Prevents implant movement during bone healing → critical for trauma recovery.
4. Revision Spinal Surgeries
   • Replaces worn/damaged nuts in existing long-tail screw systems → restores fixation integrity.
   • Compatible with older spinal implants → simplifies revision workflows.
