The incidence of femoral fractures is on the rise as society ages, and treating intertrochanteric fractures in elderly patients is a great challenge for many physicians, mainly because many of these patients suffer from severe osteoporosis and internal Increased surgical risk. Therefore, the selection of the best fixation method and instruments is crucial to obtain a positive therapeutic effect.
PFNA intramedullary nail, designed for unstable intertrochanteric fractures. The main features of the (PFNA) are the introduction of a 6.5 mm anti-rotation ring screw, grooves on the screw tip to reduce stress, and more proximal positioning of the distal locking screw to avoid sudden changes in structural stiffness. It increases the physical interface of the bone graft, leading to bone consolidation and providing excellent stability during fixation. In the treatment of osteoporotic femoral intertrochanteric fractures, PFNA has the characteristics of less trauma, shorter operation time and faster postoperative recovery.
High subtrochanteric fractures
Low subtrochanteric fractures
Femoral shaft fractures
Isolated or combined medial femoral neck fractures
Low and extended subtrochanteric fractures
Ipsilateral trochanteric fractures
Combination fractures (in the proximal femur)
Physician education, training, and professional judgment must be relied upon to select the most appropriate device and treatment.
1. Any active or suspected latent infection or significant local inflammation in or near the affected area.
2. Damaged blood vessels can inhibit adequate blood supply to the fracture or surgical site.
3. Bone mass damaged by disease, infection, or prior implantation that does not provide adequate support and/or fixation for the device.
4. Obesity. Overweight or obese patients can place loads on the implants that can cause device fixation failure or
5. Failure of the device itself.
6. Patients with insufficient tissue coverage at the surgical site.
7. Use of implants that would interfere with anatomy or physiology.
8. Any psychiatric or neuromuscular disease that creates an unacceptable risk of fixation failure or complications in postoperative care.
9. Other medical or surgical conditions that would preclude the potential benefit of surgery.
