What is the technology of Pfna Nail?
PFNA (Proximal Femoral Nail Antirotation) Femur Nail is a minimally invasive internal fixation system specially developed for proximal femoral fractures.
What are the advantages of Femur Intramedullary Nail?
Biomechanical Stability
Intramedullary Nail adopts a single helical blade design. By compacting cancellous bone, the blade delivers anti-rotational and angular stability, making it particularly suitable for osteoporotic fractures in elderly patients. Clinical studies have demonstrated that the helical blade preserves bone stock and elevates bone mineral density, thereby lowering the risk of postoperative implant failure.
Minimally Invasive Surgical Characteristics
Small incision: Only a lateral longitudinal incision of approximately 5 cm is required; the fracture site is not exposed, which reduces soft tissue trauma.
Short operative time: The procedure can be completed within 30 to 60 minutes on average, over 30% shorter than traditional plate-screw fixation systems.
Limited blood loss: Intraoperative blood loss is controlled at 50–100 mL, markedly less than that of open surgery.
Support for Accelerated Rehabilitation
Patients can get out of bed for ambulation 3 to 5 days postoperatively. Based on clinical data of over 200 cases, the 5-year survival rate exceeds 80%, rendering this technique ideal for elderly patients with multiple comorbidities.
