Abstract
A bone peg configured for cooperation with a threaded aperture on a bone plate for use in stabilizing a fracture of a bone can include a head portion and a shaft portion. The head portion can have a head threaded portion that incorporates head threads having a first pitch. The shaft portion can extend from the head portion to a distal end of the bone peg. The shaft portion can include (i) a shaft threaded portion that incorporates shaft threads having a second pitch, (ii) a first unthreaded portion and (iii) a second unthreaded portion. The shaft threaded portion is disposed intermediate the first and second unthreaded portions. The first unthreaded portion axially offsets the head threaded portion from the shaft threaded portion.
