Figure 2

Differences in the pathomechanism of low lumbar osteoporotic vertebral collapse (OVC) in patients with or without Parkinson’s disease (PD). (A) OVC is most frequent at the thoracolumbar junction, such as at T12 and L1, due to anterior loading on the spine. (B) Most non-PD cases have old thoracolumbar compression and decreased lumbar lordosis (L1-S1). (C) Most patients with PD have decreased lumbar lordosis without old thoracolumbar compression. Cases with decreased lumbar lordosis (B, C) have increased middle and/or posterior loading on the low lumbar spine after changes in spinal alignment.
