The Application Of Anterior Lateral Decompression For Thoracolumbar Burst Fracture

Objective:To access the outcome of anterior lateral decompression for thoracolumbar burst fracture with nerve injury.Methods :To analyse the clinical data of twenty patients in our department of thoracolumbar burst fracture with nerve injury of anterior lateral decompression and internal fixation with titanium mesh bone graft from August 2013 to March 2015.Radiographic data including vertebral height compression percentage,Cobb angle, spinal canal encroachment rate.In comparison to the recovery of spinal cord injury according to the ASAI classification.All data was collected pre-operation,3 days, 3 months, 6 months and 12 months of post-operation.Results:Twenty patients were followed up after operation for 3 months to 1 year.The percentage of preoperative vertebral height compression was 55.6% + 14.8%, the Cobb angle was 26.8°±3.2°,the spinal canal encroachment rate was 37.8% + 12.6%;Three days after surgery,the vertebral height compression percentage was 96.2% + 6.4%.,the Cobb angle was 5.4°±1.7°,the spinal canal encroachment rate was 37.8% + 12.6%; The last follow-up fractures of vertebral height compression percentage was 93.8% + 6.8%, Cobb angle was 7.2°±2.1°,the spinal canal encroachment rate was2.6%±3.0%; There was statistically significant in post-operation and the last follow-up, when compared with per- operation(P<0.05)。The recovery of spinal nerve injury was satisfactory compared with preoperative.Conclusion:In the treatment of thoracolumbar burst fracture with nerve injury anterior lateral decompression can restore vertebrae height effectively, correct spinal kyphosis, decompress the spinal canal completely and directly,firm internal fixation and improve the never function obviously, which was an ideal method.
