External fixation frames and fixing pins therefor

摘要

A fixation frame (12) and associated pins (22) for use in fracture surgery, are arranged so that the pins do not transfix the bone. The ends of the pins have a tip which is located in a previously drilled opening in the bone cortex, and a shoulder engages the bone outer wall to prevent penetration of the pin into the central bone tissue. The pins are secured in pin holders 20 which are also used to locate drill guides, the drill guides being used to accurately drill and form the pin openings. IMAGE
