To discuss the effectiveness of posterior short-segment fixation including the fractured vertebra for severe unstable thoracolumbar fractures using pedicle screw fixation. Between May 2008 and July 2013, 52 patients of severe unstable thoracolumbar fractures were treated through posterior short-segment fixation including the fractured vertebra using pedicle screw fixation. There were 33 males and 19 females with an age of 21-56 years (mean, 37.9 years). The causes of thoracolumbar burst fractures included fall from height in 32 cases, traffic accidents in 16 cases, and others in 4 cases. The load sharing classification (LSC) score was 7-9 (mean, 7.85). The levels involved included T in 4 cases, T in 19 cases, L in 25 cases, and L in 4 cases. According to Frankel classification, there were 2 cases of grade A, 4 cases of grade B, 8 cases of grade C, 11 cases of grade D, and 27 cases of grade E. The rate of spinal canal occupying was 24.2%-76.7% (mean, 47.1%). The time from injury to operation was 3-5 days (mean
