Gamma Interlocking Nail

Design Features of Femur Gamma Interlocking Nail

1. Nail Options:
   • Short and Long Nails: Available in both short and long lengths to accommodate various clinical needs.
   • Universal and Specific Designs: Short nails are universal for both right and left femurs, while long nails are designed specifically for right or left options.
2. Anatomical Design:
   • Anterior Bowing: Designed with anterior bowing to align with the natural curvature of the femur, enhancing fit and stability.
   • Medial-Lateral Curve: This feature ensures compatibility with the femoral anatomy for optimal load distribution.
3. Entry Point:
   • Trochanteric Entry Point: Facilitates precise placement and access during surgical procedures.
4. Proximal Locking Mechanism:
   • 125-Degree Angulation: The proximal design allows for two lag screws of 10.4mm and a 6.3mm anti-rotational screw to provide secure fixation.
5. Cannulated Design:
   • Guide Wire Compatibility: The nail is cannulated for easy insertion over a guide wire, promoting accurate placement while minimizing tissue disruption.

Locking Screws

6. Screw Specifications:
   • 10.4mm Cannulated Lag Screws: Designed for optimal fixation.
   • 6.3mm Anti-Rotational Screws: Enhance stability and prevent rotational displacement.
   • 4.5mm Locking Screws: Used for distal locking options.
   • Self-Tapping Screws: Simplifies the installation process.
7. Locking Options:
   • Static and Dynamic Distal Locking: Allows for flexibility in the stabilization approach based on fracture type and surgeon preference.

Clinical Advantages

8. Indications for Use:
   • Stable and Non-Stable Intertrochanteric Fractures: Specifically designed to address these types of fractures effectively.
   • Alternative to Compression Hip Screws: Provides a different approach to managing hip fractures.
9. Minimally Invasive Approach:
   • Reduced Trauma: The closed operating technique can lead to less trauma for the patient.
   • Limited Incision: A small incision at the tip of the greater trochanter minimizes blood loss and potentially decreases operative time.
10. Biomechanical Stability:
    • Early Weight Bearing: The stable construct allows for early weight-bearing post-surgery.
    • Biomechanical Advantage: The load-bearing axis of the Gamma Nail is closer to the hip joint fulcrum, reducing the effective lever arm on the implant and femur by approximately 25% compared to extramedullary plate systems.
