Abstract
An internal fixation pin comprises first and second portions with threads of different diameters, but having the same pitch and thread depth. The first portion includes a self-tapping tip. No enlarged head portion is provided to the pin at the end opposite the tip. A non-threaded shaft portion is frangibly connected to the second portion and is a mechanism for rotating the pin for threaded insertion into bone. A plurality of circumferentially spaced-apart longitudinal grooves are provided on the second portion adjacent its intersection with the shaft portion. After insertion of the first and second portions across a fracture, the shaft portion is removed. The grooves permit rotation of the pin for removal should removal be necessary. A driver for pin removal is also provided, as well as a mill tool.
