Product Introduction
The 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 to enhance rotational and angular stability and increase 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 both dynamic and static modes for different clinical requirements.
• Titanium Alloy Construction: manufactured from Ti-6Al-7Nb (Ti-6Al-7Nb / TC4 referenced in product meta), combining mechanical strength and biocompatibility.
• Secure Tension Pin Retention: tail cap design retains the tension pin to help prevent unintended displacement.
• Anatomical Configuration: features a 5° lateral offset and a 1500 mm anterior bow to correspond to femoral anatomy.
• Elastic Tip and Groove Design: facilitates controlled insertion and stress distribution along the implant.

Advantages

• Enhanced rotational stability via bone-compacting helical blade, suitable for osteoporotic bone.
• Load-sharing intramedullary fixation that helps distribute stress and supports fracture healing.
• Minimally invasive approach with stable fixation to facilitate early mobilization and rehabilitation.

Application

• Internal fixation of femoral intertrochanteric fractures (including unstable patterns).
• High and low subtrochanteric fractures.
• Femoral trochanteric fractures and trochanteric fractures combined with ipsilateral femoral shaft fractures.
• Pathological femoral fractures and complex multiple fractures requiring intramedullary fixation.
