The Tibia Intramedullary Nail is a load-sharing internal fixation device designed for the treatment of tibial shaft and metaphyseal fractures. It is inserted into the medullary canal of the tibia, typically through an entry point at the proximal tibia, and provides stable fixation while preserving the periosteal blood supply and minimizing soft tissue disruption.

Made from biocompatible materials such as titanium alloy or stainless steel, tibial nails are available in various lengths, diameters, and curvatures to accommodate patient anatomy and fracture type. The design includes proximal and distal locking options, which allow for static or dynamic locking configurations, ensuring rotational and axial stability.

Advanced designs may include multi-planar locking, cannulated versions for guidewire insertion, and angle-stable locking screws for enhanced fixation in osteoporotic or comminuted bone.
