Proximal Femoral Nail Type I – Single Lag Screw
The PFNA (Proximal Femoral Nail Anti-rotation) is an advanced intramedullary implant specifically designed for the treatment of hip fractures, particularly unstable intertrochanteric and proximal femoral fractures.
This system achieves stable fixation by sharing the load with the bone through the intramedullary nail, significantly reducing the risk of implant loosening and failure.
Made from titanium alloy, PFNA combines excellent biocompatibility with mechanical strength to ensure long-term durability and patient safety.
Intramedullary Nail Features
● Helical Blade Design: The unique helical blade compacts cancellous bone, providing rotational and angular stability, especially beneficial for osteoporotic patients, enhancing implant fixation.
● Anti-Rotation Mechanism: The blade prevents rotational movement of the nail within the femur, ensuring stable fracture healing.
● Locking System: Distal locking options provide axial stability with dynamic or static locking modes to enhance overall fixation strength.
● Material Advantages: Manufactured from titanium alloy (Ti-6Al-7Nb) , balancing strength and biocompatibility while minimizing postoperative rejection risks.
● The wide blade plane allows for better bone holding during implantation and reduces bone loss
● The tail cap is designed to hold the tension pin to prevent it from exiting
● 5° outward deviation and 1500mm front arch, perfectly matching the physiological structure of the human body.
● Optional dynamic or static locking to meet different clinical needs
● The elastic tip and groove design facilitates the insertion of the main pin and achieves ideal stress distribution
