The FNAS is designed to provide stable fixation and rotational control during femoral neck fracture repairs and hip procedures, preventing post-operative displacement and promoting optimal bone healing.
They are primarily utilized in orthopedic surgery for femoral neck fracture internal fixation, reconstructive hip surgeries, and selected osteotomy procedures where anatomical precision and antirotation are required.
The included 130° Angled Guide facilitates accurate drill positioning and guide wire insertion aligned with the anatomical neck-shaft angle of the femur, ensuring reproducible implant placement.
The calibrated 4.0N.m torque limiter prevents over-tightening during screw fixation, reducing the risk of bone stripping and ensuring uniform holding strength.
The system is housed in a dedicated, high-durability Instrument Box configured for systematic component arrangement, standard hospital autoclaving, and rapid identification in the operating room.
Yes, the φ3.2*400 guide wires are manufactured from medical-grade surgical alloy to provide distinct radio-opacity for real-time X-ray verification during navigation and placement.
