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. Manufactured from Ti-6Al-7Nb titanium alloy, the PFNA combines mechanical strength with biocompatibility. The intramedullary nail incorporates multiple design features, including a 5° lateral offset, 1500 mm anterior bow, optional dynamic or static distal locking, and an elastic tip and groove design for controlled insertion and stress distribution.

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 both dynamic and static modes to suit clinical requirements.
• Titanium Alloy Construction: Manufactured from Ti-6Al-7Nb (titanium alloy) combining strength and biocompatibility.
• Secure Tension Pin Retention: Tail cap design retains the tension pin to prevent unintended displacement/back-out.
• Anatomical Configuration: 5° lateral offset and 1500 mm anterior bow to match physiological femoral anatomy.
• Elastic Tip and Groove Design: Facilitates insertion of the main nail and contributes to stress distribution along the implant.

Advantages

• Enhanced Rotational Stability: Blade compaction provides superior rotational/ angular stability, useful for unstable proximal femoral fractures.
• Load-Sharing Fixation: Intramedullary nail shares mechanical load with bone and distributes stress.
• Adaptation to Poor Bone Quality: Blade compaction is suitable for osteoporotic or compromised bone.
• Minimally Invasive Fixation: Intramedullary approach reduces soft-tissue disruption.
• Support for Early Mobilization: Stable fixation facilitates postoperative mobilization and rehabilitation.

Application

• The 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.
