Technology Overview

Introduction
The X90 Pedicle Screw System exemplifies X-spine’s commitment to innovation in spinal fixation. Through the elimination of traditional set screws and locking caps, this unique integral-locking platform achieves functional simplicity, eliminates assembly steps, and delivers proven results.

By utilizing the principles of mechanical integration, the X90 System platform eliminates the potential for post-operative
disassembly due to set screw loosening or head disassembly.

The X90 System Technology platform provides a comprehensive solution for the treatment of the thoracic, lumbar, and sacral regions of the spine.

Addressing postoperative disassembly:
Mechanical Integration

Eliminates all in vivo assembly:

• No locking cap or set screw
• No separate head assembly
• Locking components pre-assembled
  under controlled conditions

Eliminates reliance on torque alone:

• Avoids metal on metal threads
• Eliminates cross-threading and uncontrolled head splay
• Uses cold-welding to achieve locking stability
• Provides positive stop to confirm locking at a predetermined position
• Prevents false locking

Minimizes the number of parts in a fixation construct:

• Avoids separate caps/rings/clips/covers
• Reduces risk of disassembly
