Abstract
An external distractor to gradually enlarge the distance between first and second bone parts includes first and a second connection devices. The first and second connection devices are connected to the first and second bone parts, respectively, with first and second respective bone pins. The distractor includes an adjustment device between the connection devices for adjusting the distance between the connection devices along an adjustment axis. The adjustment device includes a tubular base body coupled to the first connection device, an extension tube coupled to the second connection device and an adjustment mechanism for moving the extension tube with respect to the base body along the adjustment axis. The adjustment mechanism includes a rotatable adjustment ring for moving the extension tube upon rotation of the adjustment ring around the adjustment axis. The adjustment mechanism includes a spring engaging the adjustment ring for preventing unintended activation of the adjustment mechanism.
