The 3.9 mm Interlocking Screw is a specific type of locking screw used primarily to secure long bone intramedullary nails to the bone. The interlocking design provides crucial rotational and axial stability to the fracture site by preventing the nail from rotating or sliding. This screw is characterized by its slightly larger diameter of 3.9 mm and its coarse thread profile suitable for diaphyseal bone fixation. It is designed for use as a securing element in various long bone systems and is available in a precise range of lengths.

Key features include:

• Fixed Diameter: Diameter of 3.9 mm.

• Interlocking Function: Secures intramedullary nails, providing rotational stability.

• Primary Use: Distal and Proximal fixation points for long bone interlocking nails.

• Length Range: Lengths available from 24 mm to 50 mm (with 2 mm variation).

• Material Options: Available in both Stainless Steel and Titanium.
