OBJECTIVE: To analyze the thoracic and lumbar burst fractures and make a correlation of the biomechanical sagittal segment affected with the structural changes of the fractured vertebra. METHODS: A retrospective study of 72 patients with thoracic and lumbar burst fractures. The narrowing of the spinal canal, vertebral collapse and local kyphosis were evaluated in three distinct segments: thoracic, thoracolumbar transition, and lumbar. RESULTS: There was a statistically significant difference (p<0.05) in the spinal canal narrowing and kyphosis in the different segments of the spine evaluated. CONCLUSION: Burst fractures of the thoracic and lumbar spine, although with similar characteristics regardless of where they occur, are influenced directly by the biomechanical sagittal segment with respect to structural changes that occur in the fractured vertebra.
