Abstract
The significant medical discoveries are not serendipitous or fortuitous; bone regeneration is the outcome of painstaking and meticulous efforts devoted to histology, myology, skeletology, cytology, osteology, traumatology and orthopaedics. Bone regeneration, reparative and restorative techniques of bone length discrepancies, correction of posttraumatic and congenital defects and deformities can be induced through distraction osteogenesis which is achieved by Ilizarov device. It helps in regenerating bone and tissue formation through tensile force or distraction tension stress. A gap is made by the external fixator in the bone ends to be filled in with natural bone and tissue cells. This technique requires time and periodic adjustments to the external fixator to induce gradual distraction which generates osteogenesis.
