Inose et al reported risk factors for fracture nonunion after an acute osteoporotic vertebral fracture. These can help to identify a patient who may benefit from more aggressive management. The authors are from multiple institutions in Japan.
Patient selection: acute osteoporotic vertebral fracture
Nonunion on MRI was defined as a gas or fluid filled cleft separating the superior and inferior end plates at 48 weeks after injury
Risk factors for nonunion:
(1) T1-weighted MRI: diffuse low intensity pattern
(2) T2-weighted MRI: diffuse low intensity pattern
(3) T2-weighted MRI: fluid intensity pattern
Other patterns not associated with nonunion: confined low intensity, diffuse high intensity, confined high intensity
