The Femoral Neck System (FNS) is a dedicated solution for femoral neck fractures, designed for improved angular stability1 and rotational stability with the intent to reduce reoperations related to fixation complications. 
The FNS implants form a fixed-angle gliding fixation device that allows for controlled collapse of the femoral neck, similar to existing dynamic hip screw systems. The lateral element is comprised of a small base plate with one or two locking hole options. Due to the small size of the base plate, a single plate barrel angle can cover the clear majority of caputcollumdiaphyseal (CCD) angles without major angulation and offset of the base plate on the lateral aspect of the femur. The barrel allows for gliding of the head elements, in this case the locked combination of bolt and antirotation screw, while simultaneously restricting rotation around the head-neck axis.
Features of the Femoral Neck System :
• Cylindrical bolt design intended to maintain reduction during insertion
• Side-plate and locking screw(s) to provide angular stability
•Integrated bolt and antirotation-screw (ARScrew) to provide rotational stability (7.5° divergence angle)
• Dynamic design of integrated bolt and antirotation-screw (ARScrew) allows for 20 mm of guided collapse
Contraindications：
• Sepsis
• Malignant primary or metastatic tumors
• Material sensitivity
• Compromised vascularity
