| Abstract |
Objective
s: To analyze the fracture type and adjacency of accompanied fractures in acute osteoporotic spinal
compression fracture using whole spine sagittal MRI (WS-MRI), and to know the relation of sagittal vertical axis
(SVA), body mass index (BMI), and lumbar bone mineral density (BMD).
Methods
From June 2007 to December 2010, 167 patients who had acute spinal compression fractures confirmed by
WS-MRI divide in three groups. 82 patients (M/F : 25/57) who had acute fractures only were in group 1, 79 patients
who had acute and old fractures were in group 2, and 20 patients who had acute fractures after vertebroplasy were in
group 3. To analyze the fracture type and adjacency of accompanied fractures in acute osteoporotic spinal compression
fractures which combined chronic fracture or vertebroplasty using the WS-MRI and compared with the control group
who had no spinal fractures measured the SVA. In all groups, we measured BMI, and BMD.
Results
In WS-MRI, 31 patients in group 1 had L1 which was the most common fracture site. Twenty two patients
had chronic fractures and more than 3 remote levels at the acute fracture site in group 2 and especially among there
14 patients have each level in cervicothoracic and lumbar vertebrae. In group 3 had old fracture and adjacent fracture
was 14 and 11 patients. Compared with the control group, all groups had increased SVA, especially in group 2 which
has acute and chronic compression fractures. They have no significantly difference of BMI in each group, but group
2 and 3 had a significant lower BMD than group 1.
Conclusion
Fourteen patients of coexisting fractures in acute osteoporotic spinal compression fractures with WS-MRI
which could be missed in the conventional MRI. Additionally this study suggests that longer SVA causes sagittal
imbalance, and BMD is more relative than BMI in refractures of chronic compression fracture patients. |
