What is Pfna fracture?
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 intramedullary nail made of?
Intramedullary nails, used to repair fractured femurs, are currently made from stainless steel or a titanium alloy. The nail is slightly curved (typically a 1 cm bow over a 30 cm length) and hollow. Some designs have a longitudinal slit and holes at either end in which to locate fixing screws.
What is Cephalomedullary nail fixation?
The Cephalomedullary Nail was designed to help treat fractures of the femur, especially intertrochanteric and subtrochanteric fractures. The nail features a small proximal section that is designed to minimize the amount of bone that must be removed for nail insertion.
What is trochanteric fixation nail?
The Titanium Trochanteric Fixation Nail (TFN) is intended to treat stable and unstable fractures of the proximal femur including pertrochanteric fractures, intertrochanteric fractures, basal neck fractures, and combinations thereof.
What is Pfna in surgery?
Proximal Femoral Nail Antirotation (PFNA) is an intramedullary implant for the treatment of trochanteric femoral fractures, with the additional option of augmentation.
What does Pfna mean?
A new device designed by AO/ASIF, the PFNA (proximal femoral nail antirotation), represents a unique intramedullary nail system for improved management, particularly in the elderly. The aim of the present study was to analyze the results of treatment with PFNA in 50 patients with trochanteric fractures.
What are tibial nails made of?
Modern tibial nails are composed of either a titanium alloy or stainless steel and provide a variety of locking options at their proximal and distal ends.
Is Cephalomedullary the same as intramedullary?
This new class of intramedullary nail, the so-called “cephalomedullary nail” includes the Long Gamma Nail (LGN), the Trochanteric Femoral Nail (TFN), and the Intertroch/Subtroch Nail (ITST).
What does Cephalomedullary mean?
Cephalomedullary nailing is the surgical stabilization of the fracture with an intramedullary device usually inserted through the piriformis fossa, the tip or lateral greater trochanter, or the medial greater trochanter.
When was the trochanteric fixation nail released?
In 1958, the AO formulated four basic principles, which have become the guidelines for internal fixation1,2. The Synthes Titanium Trochanteric Fixation Nail (TFN) is intended to treat stable and unstable pertrochanteric fractures, intertrochanteric fractures, basal neck fractures, and combinations thereof.
What is tibia nail?
Currently available tibial nails have locking screw holes close to both ends, in multiple orientations, for better fixation of proximal and distal fractures. The nails may be either solid or cannulated (hollow). Solid nails may protect somewhat against infection because they have no internal dead space.
Are rods in bones permanent?
Once the bone has fully healed, the rod/nail no longer serves a purpose and may be removed. This is typically done a year after the original surgery and can be an outpatient procedure (i.e., the patient does not stay in the hospital overnight after surgery).
