Abstract
The invention contemplates a compression wire for fixated retention of a fractured small bone fragment in an osteosynthesis procedure. The wire comprises a smooth-walled shank portion and an adjoining threaded portion, of lesser diameter than the diameter of the shank portion, there being a step-down shoulder between the shank portion and the threaded portion. The shank portion is adapted for chucked engagement to a portable rotary drill, and the distal end of the threaded portion is configured for self-tapping entry into and threaded implantation in bone. The implantation is complete when the shoulder engages cortex tissue of the fragment, holding the same in compression against remainder structure of the fractured bone. Once implanted, the shank may be nipped by a cutter tool at relatively close offset from the shoulder.
