Abstract:

To investigate the relationship between vertebral endplate injury and adjacent intervertebral disk injury of patients with acute or sub-acute  osteoporotic vertebral compression fractures（OVC-F）by MRI,and to provide basis for  diagnosis of OVCF.Methods  The clinical data of  a  total of 66 patients with  OVCF underwent vertebroplasty(76 fracture of vertebral bodies)were selected.The vertebral endplate injury and adjacent intervertebral disk
 injury of OVCF patients were detected by MRI.Results There were 57 vertebral endplate injury in 76 fracture vertebral bodies(75%).There were only 27 vertebral bodies with vertebral endplate injury in 57 fractrue vertebral bodies with endplate injury(47%),and  22 vertebral bodies with superior and inferior vertebral endplate injury (39%),and  8 vertebral bodyies with inferior vertebral endplate injury(14%).There were 48 vertebral bodie
s with intervertebral disc injury in 76 fracture vertebral bodies(63%).There were 22 intervertebral disc injury located above the fracture of the lumbar spine in 48 vertebral bodies with intervertebral disc injury (45%),and  19 fracture vertebral bodies with upper and lower intervertebral disc injury(40%),and  7 intervertebral injuries located below the fracture of the lumbar spine(15%). Conclusion  Vertebral endplate injury is frequently associated with the adjacent intervertebral disk injury.The clinical diagnosis and treatment should be empha
sized in the fracture vertebral endplate damage and adjacent intervertebral disc injury.
