Are subtrochanteric fractures stable?
Fixation of subtrochanteric femur fractures may present complications, including malunion, delayed union, or nonunion, and is thought to be related to early fracture stability.
What three deformities are commonly seen in a subtrochanteric fracture?
Subtrochanteric fractures often are associated with intertrochanteric fractures. The strong gluteal and thigh muscles create a classic deformity. The proximal fragment is held in abduction, flexion, and external rotation. The gluteus medius and minimus attach at the greater trochanter and provide an abduction force.
How long does it take for a subtrochanteric fracture to heal?
Results. All 76 cases of femoral subtrochanteric fracture were followed up for 6–24 months. One patient had delayed healing, and the others healed uneventfully. The fracture healing time was 4.5 months on average.
What is Pfna fracture?
Currently, intramedullary devices are widely used for the treatment of trochanteric femoral fractures. 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.
How is a subtrochanteric fracture treated?
Intramedullary fixation is the treatment of choice for subtrochanteric fractures because it allows splinting of the whole of the femoral shaft.
What is a subtrochanteric fracture?
Subtrochanteric (ST) femur fractures are defined as fractures of the proximal femur that occur within 5 cm of the lesser trochanter. 1. Overall, the incidence of these fractures has been estimated to be approximately 15–20 per 100,000 individuals.
Is subtrochanteric fracture a hip fracture?
Subtrochanteric hip fracture is a break between the lesser trochanter and the area approximately 5 centimeters below the lesser trochanter.
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 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 a subtrochanteric fracture of femur?
What is a Pfna?
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.
