Objective To explore the clinical outcomes of posterior unilateral transpedicular decompression with interbody bone fusion and internal fixation for treatment of thoracolumbar burst fracture of Denis type B. Methods A retrospective study was done on 12 patients with thoracolumbar burst fracture of Denis type B who were treated by this method from April 2008 to January 2011； There was 8 males and 4 females with an average age 35.5 years(rang, 20~55 years). Fracture reduction，graft fusion，neurological function recovery，correction loss，lumbar activities and adjacent segment degeneration were observed through preoperative，immediate postoperative and final following-up X-ray，CT and neurological examinations to evaluate the clinical efficacy. Results The surgical duration ranged from 150 to 200 minutes, averaging 160 minutes, and the bleeding volume ranged from 200 to 700 ml, averaging 450 ml. They were followed up for 12 to 36 months, averaging 21.5 months. The results showed the vertebral fusion time was 3~6 months, and no loss of vertebral height was observed. All patients had obtained improvement of neurological function by 1-2 ASIA grades. The complications such as disruption, breaking or loosening of the screwrods, collapse, refractory low back pain, limitation of motion and degeneration of adjacent intervertebral disc were not observed. Conclusions: As long as indication is correctly chosen, posterior unilateral transpedicular decompression with interbody bone fusion and internal fixation can effectively achieve restoration of the spine curvature, complete decompression of the spinal canal， strut fusion of the anterior column, and preservation of the inferior part of the fractured vertebral body and the intact disc under the injured vertebra. Reduction of the incidence of adjacent intervertebral disc degeneration can also result from this surgical approachThoracolumbar burst fracture; Spinal fusion; Ppedicle screw internal fixation
