What is a gamma nail?
The Gamma nail (Fig. 2) consists of a large intramedullary locked nail with a valgus curvature, an upper part shaped as a funnel, a large proximal opening to allow insertion of a long femoral neck screw and two small horizontal holes to allow for distal locking. The femoral neck screw can slide within the nail.
What is proximal femoral nail?
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. Longer nails are designed to treat low and extended subtrochanteric or combined trochanteric and femoral shaft fractures.
Why is it called a gamma nail?
Initially it was called Halifax Nail after the place where it was developed by Dr. Subhash Haldar. A group of surgeons from Strasbourg2 changed the name of this nail to a universal one i.e. Gamma Nail as the shape resembled the Greek letter.
What is PFN surgery?
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. In conclusion, the PFN is a good minimal invasive implant of unstable proximal femoral fractures, if closed reduction is possible.
How does a gamma nail work?
This procedure stabilizes severe fractures of the femur with a metal rod and screws implanted into the center of the bone. This system provides great strength while the bone heals.
What is a gamma nail made of?
The gamma nail consists of a funnel-shaped intramedullary nail with slight bending to reflect proximal femoral diaphyseal trochanteric morphology, a large proximal opening, which features a sliding mechanism for a large femoral neck lag screw and small holes in the distal part enabling distal femoral locking of the
What is femoral nailing procedure?
Currently, the method most surgeons use for treating femoral shaft fractures is intramedullary nailing. During this procedure, a specially designed metal rod is inserted into the canal of the femur. The rod passes across the fracture to keep it in position.
What is a femoral nail?
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 a proximal femoral fracture?
Proximal femoral fractures are a subset of fractures that occur in the hip region. They tend to occur in older patients, and in those who have osteoporosis.
What is a Cephalomedullary nail?
The Cephalomedullary Nail was designed to help treat fractures of the femur, especially intertrochanteric and subtrochanteric fractures. A lag screw is placed through the nail into the femoral head to secure the nail in place proximally and help control the different segments of the bone while healing occurs.
What is nailing in Ortho?
Intramedullary nailing is surgery to repair a broken bone and keep it stable. The most common bones fixed by this procedure are the thigh, shin, hip, and upper arm. A permanent nail or rod is placed into the center of the bone. It will help you be able to put weight on the bone.
What is a recon nail?
Reconstruction or cephalomedullary nails are specialized, antegrade, femoral, intramedullary nails designed to provide fixation into the femoral head and neck for selected, complex, proximal-femoral fractures. All reconstruction nails have an anterior bow to facilitate nail insertion.
What is the difference between PFN and Pfna?
Results: our review shows that PFN has a higher rate of biomechanical failure (4,8%) compared with PFNa (1.9%). Treatment success (avoiding cutout and cutin) of both devices depends on bone stock, stability of the fracture, correct reduction and implant positioning in the center-center of the femoral head.
How do you do PFN surgery?
Insert the femoral neck screw over the 2.8mm guide wire to the stop. Remove the wrench for the femoral neck screw, if necessary using the Hexagonal Socket (357.023). Remove and discard the 2.8mm guide wire of the femoral neck screw. Finally, remove both protection sleeves from the aiming arm.
What does TFN mean in orthopedics?
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.
