Objective:To explore an operation method with less injury,thorough spinal cord decompression,prompt post-operative three-column stability of spine and early movement for patients with thoracolumbar burst fractures in high altitude.Methods:Totally 21 patients with thoracolumbar burst fractures accepted posterior unilateral subtotal corpectomy,annular decompression of spinal cord,titanium mesh bone graft for reconstruction of anterior and middle column combined with pedicle instruments fixation.Spinal cord injury was evaluated with ASIA grade criterion.Reduction,decompression and fusion of fractures were evaluated through X-ray and computer tomography.Results:All operations were completed successfully.The mean operation time was 3.1 hours and the mean blood loss was 1180ml.Cerebrospinal fluid leakage occurred in 2 patients.No other severe complications were observed.Bone graft fusion was observed in follow-up patients.No looseness and rupture of internal fixation,no obvious loss of vertebral height,spinal radian and vertebral canal volume were observed.Nervous function improved in different degree in all patients except those who had the nervous function of grade A.Conclusion:The operation of posterior unilateral subtotal corpectomy and reconstruction of spinal three-column stability has the advantages of less injury,thorough pinal cord decompression,prompt post-operative three-column stability of spine,and can effectively restore vertebral height,vertebral canal volume,physiological radian and prompt stability of spine.It is an ideal operation method for the treatment of thoracolumbar burst fractures.
