Abstract
Callus distraction (callotasis) is a method of bone lengthening introduced into clinical practice by De Bastiani et al in the 1980s.1 A long bone is sectioned at the diaphysis, stabilized for two weeks, and then subjected to gradual distraction using a rigid external fixation device. The distraction gap fills with growing callus that is destined to develop into solid bone. A slow rate of distraction does not break the bridging callus; it stimulates osteogenesis. The bone is thus lengthened without the need for bone grafting.
