A modular intramedullary nail (10) includes three connectable sections (11, 12, 13) that are connectable end to end. The three sections include an upper proximal nail component (11), a central nail component (12), and a lower distal nail component (13). The nail components are connected using corresponding frustoconical socket (16) and frustoconical projecting end portions (19) of adjoining nail components that can be fitted together with a taper lock or morse taper connection and secured tightly together upon impact. Upon assembly, the connections are self-orienting, providing corresponding key and slot portions (23, 29) adjacent the respective frustoconical socket and frustoconical projecting end portions of the nail components. The interlocking keys and slot align and abut upon assembly so that the adjoining nail components only align in one relative position.
