The Intramedullary Nail System consists of metallic implants including interlocking intramedullary nails, interlocking fusion nails, and nail caps. Intramedullary nails contain holes proximally and distally to accept locking screws. Intramedullary Interlocking Nails are provided with a variety of screw placement options based on surgical approach, nail type and indications. Interlocking Fusion Nails indicated for joint arthrodesis have screw holes for locking on either side of the joint being fused. The locking screws reduce the likelihood of shortening and rotation at the fusion site.
