OBJECTIVE To investigate the factors which affect the bone union of distracted region after limb lengthening, so as improve the curative effect and diminish the incidence of complication. METHODS To look up the latest literatures dealing with the bone union in limb lengthening, then review the procedure of osteogenesis and the affecting factors. RESULTS The osteogenesis of distracted region after limb lengthening is a sophisticated procedure. It can be affected by the velocity of lengthening, the period of lengthening, the site and method of osteotomy, the age etiology of patient. CONCLUSION The bone union of distracted region after limb lengthening can be facilitated by following factors: 1. the velocity of lengthening slower than 1.0 mm/day; 2. moderate delay in distraction; 3. axial shortening of distracted region; 4. micromovement stimulation.
