Device for uniting bone fragments

摘要

A device for uniting bone fragments comprises a rectilinear body and a contrivance for fixing it in the coapted bone fragments. The contrivance for fixing the body in the coapted bone fragments is formed by thrust members being the portions of the body located at the opposite ends thereof and having holes coaxial with the body; the holes being shaped as frustums of cones facing with their greater bases the ends of the body, and having annular grooves in the wall thereof, and cone-shaped inserts with annular ridges adapted to be introduced into the conical holes for wedging apart the body. The body has longitudinal through slots within the zones of the holes. The length of the device is less than the total length of the coapted bone fragments so as to be located fully within the bone tissues.
