Takahashi S, Hoshino M, Takayama K, et al. - This study conducted to evaluate the change in the paravertebral muscles in patients with osteoporotic vertebral fracture. This analysis enrolled consecutive patients with symptomatic osteoporotic vertebral fractures in 11 hospitals. Researchers recruited a total of 153 individuals who completed the 6-month follow-up, out of these, 117 (92 women, 79%) had MRI of L3 at enrollment and 3- and 6-month follow-up (mean age at enrollment, 78.5 years). The study found that PVM reduction was significantly associated with low back pain and delayed union after osteoporotic vertebral fracture onset. At the 3-month follow-up, ADL decline was a risk factor for PVM decrease. Hence, it is indicated that restoring activities of daily living within 3 months after onset is important.
