[Imaging assessing symptomatic vertebral compression fracture to be treated by vertebroplasty and kyphoplasty in osteoporosis patients].

OBJECTIVE
To evaluate the values of radiology, computed tomography (CT) and magnetic resonance imaging (MRI) in assessing symptomatic osteoporosis vertebral compression fractures in vertebroplasty and kyphoplasty.


METHODS
Retrospective reviews were conducted for 41 osteoporotic vertebral compression fractures patients with preoperative CT (with 3D reconstruction)/MRI (with fat saturation sequence) and preoperative and postoperative radiological imaging data. All patients underwent percutaneous vertebroplasty (PVP) or balloon kyphoplasty (BKP) when conservative treatment failed to offer pain relief.


RESULTS
CT scan showed 52 vertebral fractures while MRI detected a total of 70 lesions of vertebral body, including 44 new fractures, 8 old fractures and 18 bone bruises. Eight old fractures and 2 mild bone bruises were treated conservatively. In conjunctions with MRI, especially fat saturation sequence, 60 therapeutic vertebral bodies were visualized. It was superior to CT. As demonstrated by preoperative and postoperative radiology, vertebral body height improved and Cobb Angle slightly decreased for 60 lesions.


CONCLUSION
For vertebral compression fractures in osteoporosis patients, preoperative CT and MRI examinations have important clinical significance in providing treatment guidance and assessing postoperative outcomes.
