The Austofix F1 Hip Nail complements the Austofix Nail Range; for antegrade femoral nailing indications. The proximal femoral nail antirotation (PFNA), designed by AO, is an intramedullary device with a helical blade rather than a screw for better purchase in the femoral head and was tested in a clinical study. Determine nail insertion point and insert Guide Wire In the AP view, the nail insertion point is normally found on the tip or slightly lateral to the tip of the greater trochanter in the curved extension of the medullary cavity.

However, proximal femoral nail antirotation was designed according to the geometric proportions of the White population, and it is known that important differences exist between Asians and Americans with regard to femoral geometry. 2019 Oct 29;20(1):500. doi: 10.1186/s12891-019-2793-8. Table 3:Long Vs Short PFN. The exact location of the skin incision depends on the type of insertion handle / type of nail used.

Consecutive patients with unstable trochanteric fractures (AO-classification 31.A.2 and A.3 only) were included and followed for 1 year. In the case of a malunion or non-union, a possible solution to the problem is by surgically inserting an intramedullary rod into the center canal (diaphysial) region of the injured bone and fixating it into place with screws.

PFN Nail (Proximal Femoral Nail) Long sizes: Distal diameter 9-12 mm, Angle 130° or 135°, Length from 320 to 420 mm. 0 Number of Embeds.  Due to its position close to the weight-bearing axis the stress generated on the intramedullary implants is negligible. Bone fractures are a very common orthopedic injury resulting from trauma and sudden loads or stresses applied to bones or a result from bones being weakened by certain diseases.  limits the surgical insult to the … Reports of serious postoperative complications also exist when used for the elderly Asian population. As shown, this lies on the proximal extension of the bowed axis of the femoral shaft. Proximal Femoral Nail Antirotation Technique Guide DePuySynthes 11. BY ALEX BERTINO, COREY VAN DE HAY, ANDREW HNAT Operative technique: • Anaesthesia: All the patients were operated under either spinal anaesthesia or epidural anaesthesia. A femoral nail with proximal cephalomedullary locking options is inserted. d) Acts as a buttress to prevent shaft medialisation . Evidence based approach b) Shorter lever arm can decrease tensile strain on implant and risk of implant failure. The TFN-ADVANCED Proximal Femoral Nailing System (TFNA) 235 mm (DePuySynthes) and Proximal Femoral Nail Antirotation (PFNA)-II 240 mm (DePuySynthes) were developed to achieve better stability for patients with trochanteric hip fractures without increasing surgical time and blood loss.

Bone fractures are either a complete or partial break in a bone and in some cases a simple cast to immobilize the injury site is not enough to completely heal the fracture. Immobilization from casts may not be enough to completely heal the fracture if a malunion (when both ends of the fractured bone misalign) occurs and/or if a non-union (when the fracture gap is too large and the fractured ends cannot re-attach to one another) occurs. Nail curves Long bones have curved medullary cavities Nails contoured to accommodate curves of bone Straight, curved or helical Average radius of curvature of femur - 120(±36) cm.
