| Abstract |
Objective
The purpose of this study is to assess predictors of progressive collapse of acute osteoporotic vertebral fracture in elderly patients.
Methods
We analyzed retrospectively 56 elderly patients (≥65 years) with conservative treatment after acute osteoporotic vertebral fracture from Jan. 2014 to Dec. 2015. Clinical data and radiological data of 56 patients with acute single-level thoracolumbar or lumbar fractures were reviewed. The degree of collapse of vertebral body and kyphotic angle were measured and magnetic resonance imagings (MRI) were analyzed. Multiple logistic regression analysis was performed to identify independent predictors of progressive collapse of fractured vertebral body.
Results
Progressive collapse of fractured vertebral body was 16 patients (28.6%) in elderly patients receiving conservative treatment after acute osteoporotic vertebral fracture. Both body mass index and bone mineral densitometry were not associated with progression of collapse in acute osteoporotic vertebral fracture. Age and middle column involvement on MRI were two independent predictors of progressive collapse of fractured vertebral body (p=0.014 and p=0.049, respectively).
Conclusion
Progressive collapse of fractured vertebral body is relatively common event after conservative treatment of acute osteoporotic vertebral fracture in elderly patients. Age as well as middle column involvement on MR image may be associated with progressive collapse of fractured vertebral body in elderly patients. |
