Abstract

See full text

A bone lengthening mechanism is placed into a bone which is then lengthened by extending the mechanism. The mechanism is extended by effecting a rotational movement in a drive bolt which mates with a threaded portion in a section of the mechanism. The threads convert the rotational movement to a longitudinal force thereby lengthening the bone.
