The Ender’s Nail is a flexible intramedullary fixation device used primarily for treating fractures of long bones through elastic stable intramedullary nailing (ESIN). Typically made from stainless steel, Ender’s Nails are thin, solid rods with a curved or hooked tip that enable three-point fixation within the medullary canal. These nails are inserted in multiples (usually two or more) to provide symmetrical stabilization of the fracture and promote biological healing with minimal surgical trauma.

Ender Nails are inserted retrograde or antegrade, depending on the bone and fracture type. Their flexible nature allows the nails to conform to the natural curvature of the bone, making them ideal for minimally invasive procedures, especially in pediatric and elderly patients or osteoporotic bone.
