ABSTRACT:
A surgical tool which may be utilized either for compression or distraction of a fractured bone. The tool includes a threaded shaft having a pair of cap members secured to each end thereof. Projecting from one of the cap members is a short pin which is preferably angled either towards or away from the other cap member. An internally threaded sleeve is mounted on the shaft between the cap members and includes a knob having a knurled outer surface for permitting the sleeve to be manually adjusted in either direction along the threaded shaft. Another pin-supporting member is removably mounted about the sleeve and has another short pin projecting from one surface thereof. The two pins are positioned within pre-drilled holes on each side of a fractured bone that is to be compressed or distracted.
