PFNA2 Nail

Specifications - PFNA2 Nail

PFNA2 (Proximal femoral nail antirotation for Asia) has been developed especially for Asian patients.

The treatment of proximal femoral fractures in geriatric osteoporotic patients continues to be a challenge in orthopedic trauma. Various kinds of cephalomedullary nails, such as gamma nail, InterTan and PFNA were used clinically. The latest generation PFNA2, specially designed for Asian population, is commonly used for geriatric per-/intertrochanteric fractures. Some clinical studies have previously reported that the short-term clinical outcomes of PFNA2 are satisfactory in most patients, and it provides an anatomy matched with the narrower and shorter femurs of Asians and contributes to decreased complications.

The PFNA2 Nail has a medial-lateral angle of 5°. This allows insertion at the tip of the greater trochanter.

Several distal locking options: Static or dynamic locking can be performed via the aiming arm with PFNA2 small and medium. The PFNA2 long additionally allows for secondary dynamization.

The PFNA Nail is available in 4 sizes

  • Small, length 170 mm
  • Small, length 200 mm
  • Medium, length 240 mm
  • Large, length 260-420 mm

Inserting the PFNA2 blade compacts the cancellous bone providing additional anchoring, which is especially important in osteoporotic bone.

Increased stability caused by bone compaction around the PFNA blade has been biomechanically proven to retard rotation and varus collapse. Biomechanical tests have demonstrated that the PFNA2 blade had a significantly higher cut-out resistance in comparison with commonly-used screw systems.

All surgical steps required to insert the PFNA blade are performed through lateral incision. The PFNA2 blade is automatically locked to prevent rotation of the blade and femoral head.
