Predictors of the failure of conservative treatment in patients with a thoracolumbar burst fracture

摘要

Cobb angle was measured as the angle between the superior endplate of the vertebra above the fracture and the inferior endplate of the vertebra below the fracture. Vertebral body compression rate (VBCR) and percentage of anterior height compression were calculated as follows: VBCR = AVH/PVH × 100%. PAHC = AVH/[(AVH* + AVH**)/2] × 100%. AVH: Anterior vertebral height of the fractured vertebra, AVH*: Anterior vertebral height of a vertebra above the fracture, AVH**: Anterior vertebral height of a vertebra below the fracture, PVH: posterior vertebral height of fractured vertebra
