Femoral Intramedullary Nail

As a core implant in femoral fracture management, the PFN is inserted through the greater trochanter into the femoral medullary canal to stabilize peritrochanteric, intertrochanteric, and subtrochanteric fractures. By leveraging central intramedullary fixation, it shortens the force arm, distributes stress evenly across the fracture site, and maintains the natural biomechanical properties of the femur. This design not only enhances fixation stability but also enables early weight-bearing and functional exercise, critical for reducing complications in elderly or osteoporotic patients.

Engineered for clinical precision and surgical efficiency, the PFN integrates targeted design elements:

• Anatomically Optimized Angles: Features a 125° CCD angle and 5° medial-lateral angle, matching the natural femoral neck-shaft anatomy for seamless insertion and reduced lateral cortex pressure .
• Integrated Anti-Rotation Stability: Equipped with a spiral blade or dual-screw system (lag screw + anti-rotation screw) to eliminate rotational displacement and angular instability, with the spiral blade compacting cancellous bone for enhanced anchorage in osteoporotic patients .
• Versatile Size Range: Available in multiple lengths (80–240mm, with 5–20mm increments) and diameters (9.8mm–14mm), plus 0mm/5mm/10mm end cap options to accommodate diverse patient anatomy and fracture patterns .
• Trauma-Minimizing Design: Lateral flat cut and fluted tip reduce insertion resistance and stress concentration, lowering the risk of cortical penetration .
• Osteoporosis-Friendly Features: Incorporates bone cement holes for targeted cement injection, enhancing fixation in patients with severe bone loss .
• Efficient Instrumentation: Radiolucent carbon fiber aiming jig enables precise screw placement with minimal fluoroscopy, supporting single-instrument operation to reduce surgical time .

• Superior Biomechanical Stability: Central intramedullary fixation provides stronger anti-shear and anti-varus capabilities compared to extramedullary devices, reducing implant failure risks .
• Minimally Invasive Approach: Small incision at the greater trochanter minimizes soft tissue damage, reducing intraoperative blood loss and accelerating wound healing .
• Enhanced Bone-Brain Integration: Medical-grade titanium alloy construction promotes biocompatibility and osseointegration, while the spiral blade design preserves bone stock .
• Reduced Complication Rates: Anti-rotation and anti-cutout features lower the incidence of fracture displacement, nonunion, and implant migration-even in unstable fracture patterns .
• Surgical Versatility: Compatible with both closed reduction and minimally invasive techniques, adapting to AO/OTA 31-A1 to 31-A3 fracture classifications .

The Proximal Femoral Nail is indicated for:

• Peritrochanteric and intertrochanteric femoral fractures (AO/OTA 31-A1, 31-A2, 31-A3)
• High and low subtrochanteric femoral fractures
• Basal femoral neck fractures
• Pathological fractures of the proximal femur
• Revision procedures for failed prior proximal femoral fixation

• Material: Medical-grade Ti6Al4V ELI titanium alloy, meeting ISO 5832-3 standards for biocompatibility, corrosion resistance, and mechanical strength .
• Sterilization: Compatible with high-pressure steam sterilization for ready-to-use surgical application.
• Certifications: Adheres to global regulatory requirements, including CE and FDA approvals, and complies with ISO 13485 quality management system standards.
