Abstract
To investigate the effect of bone mineral density(BMD) and fracture site of the vertebrae on low back pain in elderly patients with osteoporotic vertebral compression fractures. From August 2011 to August 2013, a total of 107 senile patients with osteoporotic vertebral compression fractures underwent percutaneous vertebroplasty were followed up for more than 2 ( average 2.5) years in Department of orthopedics, Xuanwu Hospital, Capital Medical University. The incidence of low back pain after vertebroplasty were analyzed on visual analog scale (VAS), and the relationship between BMD, vertebral fracture site were investigated. A total of 18 cases(16.8%)after vertebroplasty have significant low back pain. Along with BMD decreased [(-2.90±0.91) vs (-4.87±0.52)], the VAS of low back pain increasing, which showed statistical significance difference[(-3.12±0.91) vs (4.03±1.08), P<0.05]. The site of vertebral fracture was lower, the VAS was higher. About 16.8% patients show obvious low back pain after vertebroplasty. BMD and Vertebral fracture site were important factors of low back pain in elderly patients with osteoporotic vertebral compression fractures after vertebroplasty.
