AIM: To observe the clinical effects of three-dimensional instrumentation in the correction of frontal, sagittal and axial plane deformity of scolio-sis. METHODS: From June 1996 to June 2001, 52 cases of scoliosis were corrected with three-dimensional instrumentation. Among them, 36 cases were treated with CD system, 5 cases were treated with TSRH, 6 cases were treated with China Greatwall and 5 cases were treated with Scofix. RESULTS: All the patients were followed-up for an average of 2 years (ranging from 1 to 4 years). The averaged frontal curve was 25. 5°(ranging from 10°to 46°), the average correction rate was 63. 6%. The average sagittal curve was 27°(ranging from 20°to 35°) . CONCLUSION: Three-dimensional instrumentation is effective in three-dimensional correction and is an excellent tool for scolioeis correction. The fixation is reliable and the complications rarely occurred.
