Multi-section intramedullary nail

An implantable modular intramedullary nail, comprising:

• a) a proximal nail component
• b) a distal nail component;
• c) a central nail component having proximal and distal end portions that are respectively connected during use to the proximal and distal nail components to define therewith upon assembly a modular intramedullary nail unit of generally uniform outer diameter having a generally smooth continuous outer surface and that is free of sharp curves, enabling the assembled nail unit to be surgically inserted into a patient's intramedullary canal;
• d) connecting members for securing the proximal and distal nail components to the respective proximal and distal end portions of the central nail component, the connection members including corresponding conical socket and conical projecting end portions of adjoining nail components that can be fitted together and secured upon impact;
• e) self orienting interlocking portions positioned adjacent the respective conical socket and conical projecting end portions for resisting relative rotational movement between the components;
• and
• f) wherein the central nail component is much larger than either of the proximal or distal nail sections.
