Product IntroductionThe PFNA (Proximal Femoral Nail Anti-rotation) is an intramedullary fixation system designed for surgical treatment of proximal femoral fractures, especially unstable intertrochanteric and subtrochanteric fractures. The system employs 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.
Key summary (from page)Model Number: 4080101
Material: Titanium Alloy (TC4) / Ti-6Al-7Nb
Application: The short (stub) nail is used for internal fixation of femoral intertrochanteric fracture and high subtrochanteric fracture. The long nail is used for internal fixation of low subtrochanteric fracture, femoral trochanteric fracture, femoral trochanter combined ipsilateral femoral shaft fracture, and pathological femoral fracture.
Features- Helical Blade Fixation: The helical blade compacts cancellous bone during insertion, enhancing rotational and angular stability at the fracture site and increasing bone contact while minimizing bone removal.
- Anti-Rotation Stability: Blade-based fixation resists rotational displacement of fracture fragments and maintains stable fixation within the femoral head.
- Flexible Locking Options: Distal locking supports dynamic or static locking modes to accommodate various clinical requirements.
- Titanium Alloy Construction: Manufactured from titanium alloy (page references TC4 and Ti-6Al-7Nb) combining mechanical strength and biocompatibility.
- Secure Tension Pin Retention: Tail cap design retains the tension pin to help prevent unintended displacement/backing out.
- Anatomical Configuration: Nail features a 5° lateral offset and ~1500 mm anterior bow to correspond with femoral anatomy.
- Elastic Tip and Groove Design: Facilitates insertion and contributes to stress distribution along the implant.
Advantages- Enhanced rotational stability through cancellous bone compaction by the helical blade.
- Load-sharing fixation via intramedullary construct for stable internal fixation and stress distribution.
- Suitable for poor bone quality (osteoporotic bone) because of the bone-compacting blade action.
- Minimally invasive approach potential: intramedullary fixation can be performed through limited exposure, reducing soft-tissue disruption.
- Designed to support early mobilization per surgeon protocol due to stable fixation.
Applications- Internal fixation of intertrochanteric fractures (including unstable fractures).
- High and low subtrochanteric fractures.
- Femoral trochanteric fractures and femoral trochanter combined with ipsilateral femoral shaft fractures.
- Pathological femoral fractures and certain complex or combined fracture patterns.
