Methods From April 1996 to June 2007, 30 thoracolumbar kyphosis patients with complete medical records and clear X-ray photograms have undergone operation. Of these 30 cases, 16 cases underwent posterior closing wedge osteotmy with instrumentation while the height of the osteotomy and the correction of the angle have been measured; 14 cases underwent spinal osteotomy with cage inserting into the intervertebral gap and closing posteriorly by a single posterior approach while the height of the osteotomy, the height and the place of the cage and the correction of the angle were also measured. A simple geometrical model was simulated to calculate the relationship between the height of the oeteotomy and the correction of the angle and these results are finally compared with the data coming from the actual measuring by the Wilcoxon statistic method. Results The distribution of data from the 16 cases by posterior closing wedge osteotomy with instrumentation was as such： 9 male and 7 female, the mean age was 49.2 years （range 38--70）, the kyphosis improved from an average of 30° （range 15°--45°） preoperatively to 4° （range -26°--30°） postoperatively, the kyphosis was corrected on average 2.5-0 per 1 mm in the height of the osteotomy. The results from the simple geometrical model were that the mean of the correction of the angle per 1 mm was 2.2°. As a result, there was no significant difference （P 〉0.05） when comparing the measurement collected with the result simulated from the geometric model.
