Abstract: For tibia four rings configuration was optimal inadequately tensioned intraosseous wires also created instability predisposing to non-union. Excessive rate of lengthening resulted in stretching and thrombosis of the newly formed tissues. Lengthening less than one milli meter per day resulted in precocious consolidation of the new bone. The study was conducted in orthopaedic department, Medical College Hospital. Around 28 cases were treated by the Ilizarov ring fixator. Of the 28 cases, 17 cases were with gross bone loss following RTA. 2 cases were shortening following PPRP- 2 case due to Perthes disease and 2 cases due to congenital cause and 5 due to osteomyelitis. The duration of treatment seem to be longer compared to other treatment modalities. This depends up on the length of the bone to be achieved. The bone grows by about 1 mm/day in unifocal corticotomy. If bifocal corticotomy is performed, more length is achieved.
