Product IntroductionThe PFNA (Proximal Femoral Nail Anti-rotation) is an intramedullary fixation system designed for the surgical treatment of proximal femoral fractures, particularly unstable intertrochanteric and subtrochanteric fractures. The system uses a helical blade fixation mechanism to compact cancellous bone within the femoral head, providing rotational and angular stability while supporting fracture fixation in patients with reduced bone quality.
Features- Helical Blade Fixation: The helical blade compacts cancellous bone during insertion, enhancing rotational and angular stability at the fracture site. Its wide blade surface provides increased bone contact during implantation while helping minimize bone removal.
- Anti-Rotation Stability: The blade-based fixation mechanism resists rotational displacement of fracture fragments and maintains stable fixation within the femoral head.
- Flexible Locking Options: The distal locking system supports both dynamic and static locking modes, allowing the fixation configuration to be selected according to clinical requirements.
- Titanium Alloy Construction: Manufactured from Ti-6Al-7Nb titanium alloy, combining mechanical strength and biocompatibility for orthopedic implantation.
- Secure Tension Pin Retention: Tail cap designed to retain the tension pin and help prevent unintended displacement or backing out of the pin.
- Anatomical Configuration: Nail features a 5° lateral offset and 1500 mm anterior bow, designed to correspond to the physiological anatomy of the femur.
- Elastic Tip and Groove Design: Facilitates insertion of the main nail and contributes to stress distribution along the implant.
Advantages- Enhanced Rotational Stability: Helical blade compacts cancellous bone and provides rotational and angular stability, supporting fixation of unstable proximal femoral fractures.
- Load-Sharing Fixation: Intramedullary nail shares mechanical loading with surrounding bone, providing stable internal fixation while helping distribute stress.
- Adaptation to Poor Bone Quality: Bone-compacting action of the helical blade is suitable for fixation in osteoporotic or compromised bone.
- Minimally Invasive Fixation: Intramedullary fixation can be performed through a relatively limited surgical approach, reducing soft-tissue disruption.
- Support for Early Mobilization: Stable internal fixation facilitates postoperative mobilization and rehabilitation according to surgeon protocol.
Application- Stub (short) nail: internal fixation of femoral intertrochanteric fractures and high subtrochanteric fractures.
- Long nail: internal fixation of low subtrochanteric fractures, femoral trochanteric fractures, femoral trochanter combined ipsilateral femoral shaft fractures, and pathological femoral fractures.
