What is PFN in Ortho?
In 1996, the AO/ASIF developed the proximal femoral nail (PFN) as an intramedullary device for the treatment of unstable per-, intra- and subtrochanteric femoral fractures.
What is PFN operation?
The proximal femoral nail (PFN) is an osteosynthetic implant designed to treat proximal femoral fractures in the trochanter area with a closed intramedullary fixation method.
What is Pfna surgery?
PFNA is an intramedullary fixation system which allows early weight bearing postoperatively. The device permits impaction of the metaphyseal fracture through the sliding helically shaped collum-blade, which can accelerate the fracture union and reduce the incidence of femoral head penetration.
What is IMN femur surgery?
An intramedullary nail is a metal rod that is inserted into the medullary cavity of a bone and across the fracture in order to provide a solid support for the fractured bone. Intramedullary nailing is currently considered the “gold standard” for treatment of femoral shaft fractures (Rudloff 2009).
What is PFN a2?
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.
What is the difference between PFN and Pfna?
PFNA has a superior performance over PFN in the setting of osteoporosis, which is attributed to compaction of cancellous bone by the helical blade. Nevertheless, it must be remembered that no implant design can compensate for poor reduction or poor implant placement in these fractures.
What is proximal femoral nail Antirotation?
Proximal Femoral Nail Antirotation (PFNA) is a recently introduced implant from AO/ASIF designed to compact the cancellous bone and may be particularly useful in unstable and osteoporotic hip fractures. This study is a single and independent centre experience of this implant used in management of acute hip fractures.
What is a intertrochanteric fracture?
Intertrochanteric fractures are defined as extracapsular fractures of the proximal femur that occur between the greater and lesser trochanter. The intertrochanteric aspect of the femur is located between the greater and lesser trochanters and is composed of dense trabecular bone.
When should femoral nails be removed?
Intramedullary nails used for fixation of femoral fractures may require removal for a variety of reasons. Some recommend that all such nails be removed after fracture healing,1,2 whereas others prefer to remove only those that cause symptoms.
