Universal PFNA-II Instrument Set & Proximal Femoral Nail Antirotation Instrument System Architecture
Conventional two-screw cephalomedullary nails require drilling two separate parallel channels in narrow femoral necks and remain vulnerable to uneven load distribution (“Z-effect” screw migration). Our Proximal Femoral Nail Antirotation Instrument System overcomes this challenge by consolidating rotational stability and axial load-bearing into a single, wide-surface helical blade.
Engineered to serve simultaneously as a standard PFNA Instrument Set and a second-generation PFNA-II Instrument Set, the instrumentation accommodates the anatomical refinements of modern Asian and Western proximal femoral nails. The stepped Ø 16.5mm / Ø 17.0mm proximal entry reamer and lateral-relief protection sleeve prevent lateral trochanteric wall impingement and hoop-stress cortical splitting during nail insertion—making the tray equally effective in smaller-stature patients and large femoral canals.
Biomechanical Compaction Engineering: Helical Blade Cephalomedullary Nail Instrument Set
In severely osteoporotic femoral heads, conventional triple reamers or large lag-screw drills remove vital trabecular bone stock. Configured as a high-precision Helical Blade Cephalomedullary Nail Instrument Set, this platform preserves native bone density through a controlled, step-by-step impaction and internal locking workflow:
- Three-Part Coaxial Protection &Buttress Nut Assembly: The outer protection sleeve, inner drill sleeve, and Ø 3.2mm guide-wire sleeve lock into the radiolucent aiming bow via a threaded lateral buttress nut, ensuring zero trajectory deflection against the lateral femoral cortex.
- Lateral Cortex-Only Opening Drill (Ø 11.0mm): Rather than reaming the entire femoral neck in osteoporotic patients, the calibrated Ø 11.0mm cannulated opening drill is engineered with a mechanical stop to open only the lateral femoral cortex, allowing the helical blade to compact cancellous bone along the remaining neck tract (a full-neck stepped reamer is also included for young patients with dense bone).
- Rotational Lock / Unlock Helical Blade Inserter: The cannulated blade impactor couples to the helical blade in an “unlocked” state so the spiral flutes rotate freely along their helical path during gentle slotted-hammer impaction. Once seated at the exact millimeter depth, rotating the inserter handle clockwise expands the internal locking core of the blade—preventing further rotation and locking the femoral head fragment.
- Controlled Interfragmentary Neck Compression: The buttress nut on the protection sleeve allows the surgeon to apply up to 5mm–7mm of controlled axial interfragmentary compression across the intertrochanteric fracture line without backing the nail out of the canal.
- Jig-Guided Short Nail & Freehand Long Nail Distal Locking: Features color-coded distal aiming ports on the targeting arm for static or dynamic Ø 4.9mm locking of short nails, plus a freehand targeting wand for distal locking of long PFNA/PFNA-II nails.
Clinical Indications: Turnkey Osteoporotic Intertrochanteric Hip Fracture Nailing Set
Fragility hip fractures in elderly patients require rapid, minimally invasive stabilization that permits immediate full weight-bearing without risk of superior femoral head cut-out. Engineered specifically as an Osteoporotic Intertrochanteric Hip Fracture Nailing Set, this platform covers the full spectrum of unstable proximal femoral trauma.
Pertrochanteric, Reverse Oblique & Subtrochanteric Applications (AO/OTA 31-A1, 31-A2, 31-A3 & 32)
- Osteoporotic Pertrochanteric & Intertrochanteric Fractures (AO/OTA 31-A1 & 31-A2): Multi-fragmentary geriatric hip fractures where helical blade cancellous compaction provides superior pull-out and cut-out resistance compared to threaded lag screws.
- Reverse Oblique & Lateral Wall-Compromised Fractures (AO/OTA 31-A3): Unstable transtrochanteric fractures where the intramedullary nail shaft acts as an internal lateral buttress to prevent femoral shaft medialization.
- High & Low Subtrochanteric Fractures: Managed using the long-nail configuration of our Osteoporotic Intertrochanteric Hip Fracture Nailing Set, combining proximal helical blade fixation with distal bi-planar shaft locking.
- Ipsilateral Femoral Neck/Shaft & Pathological Fractures: Segmental high-energy trauma and prophylactic stabilization of osteolytic metastatic lesions in the proximal femur.

Frequently Asked Questions
Q1: Is this PFNA Instrument Set compatible with both standard PFNA and Asian PFNA-II (PFNA2) nails?
Yes. Our unified Proximal Femoral Nail Antirotation Instrument System functions as both a standard PFNA Instrument Set and a PFNA-II Instrument Set. It supports 6° mediolateral bend geometries, Ø 16.5mm proximal diameters, and 130° neck-shaft angles across short and long nails.
Q2: How does the Helical Blade Cephalomedullary Nail Instrument Set prevent blade cut-out in osteoporotic bone?
Unlike standard lag screws that remove bone during reaming, our Helical Blade Cephalomedullary Nail Instrument Set uses an Ø 11.0mm drill to open only the lateral femoral cortex. As the helical blade is impacted along the Ø 3.2mm guide wire, its spiral flutes radially compact native cancellous bone around the blade tip—creating a dense bone halo that resists varus collapse and rotational cut-out.
Q3: How does the lock/unlock mechanism on the helical blade inserter work?
During insertion, the impactor threads onto the blade in an unlocked state so the spiral flutes can rotate smoothly along their helical pitch. Once the blade reaches the desired subchondral depth, turning the inserter handle clockwise advances an internal locking core inside the blade, locking its rotation and stabilizing the femoral head fragment.
Q4: What are the sterilization parameters for the PFNA / PFNA-II sterilization tray?
The anodized aluminum sterilization container is validated for standard hospital pre-vacuum steam autoclave sterilization at (132°C / 270°F) for 4 minutes with a minimum 20–30 minute drying cycle, as well as 134°C (273°F) for 3 minutes under European/WHO sterilization protocols.
Q5: As a PFNA Instrument Set Manufacturer, do you offer OEM private-label branding and custom jig calibration?
Yes. As a direct PFNA Instrument Set Manufacturer, we provide comprehensive OEM and private-label manufacturing for orthopedic implant companies and regional distributors.
