Product short info
Model Number: 4080101
Material: Titanium Alloy TC4
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.

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 is designed to resist rotational displacement of fracture fragments and maintain stable fixation within the femoral head.
• Flexible Locking Options: Distal locking supports both dynamic and static locking modes allowing selection according to clinical requirements.
• Titanium Alloy Construction: Manufactured from Ti-6Al-7Nb titanium alloy, providing mechanical strength and biocompatibility.
• Secure Tension Pin Retention: Tail cap design retains the tension pin to help prevent unintended displacement or backing out.
• Anatomical Configuration: Nail features a 5° lateral offset and 1500 mm anterior bow to correspond to 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: Helical blade compaction provides rotational/angular stability suitable for unstable proximal femoral fractures.
• Load-Sharing Fixation: Intramedullary nail shares mechanical loading with surrounding bone for stable fixation and stress distribution.
• Adaptation to Poor Bone Quality: Blade compaction benefits fixation in osteoporotic or compromised bone.
• Minimally Invasive Fixation: Intramedullary approach supports limited surgical exposure and reduced soft-tissue disruption.
• Support for Early Mobilization: Stable internal fixation designed to facilitate postoperative rehabilitation according to surgeon protocol.

Application

• Unstable intertrochanteric fractures
• High and low subtrochanteric fractures
• Femoral trochanteric fractures
• Femoral trochanter combined ipsilateral femoral shaft fractures
• Pathological femoral fractures
• Complex multiple proximal femoral fracture patterns
