Preliminary establishment of a spinal stability scoring system for multiple myeloma

Figure 1 The score indicated “spinal stability”. A, B: Lumbar spine X-ray image, showing the presence of a physiological curvature; C: A sagittal plane magnetic resonance (MR) in which T11 and L1-2 lesions are visible; D: A normal MR image.

Figure 2 The score indicated “potential instability”. A, B: Lumbar spine X-ray image showing the presence of a lumbar physiological curvature; C: Sagittal plane magnetic resonance (MR) images in which T12, L2 and S1-2 lesions are visible; D: Lumbar disc herniation on a cross-sectional MR image.

Figure 3 The score indicated “spinal instability”. A, B: Lumbar spondylolisthesis is visible from the lateral view of the patient; Lumbar computed tomography cross-sectional image that shows an L2 lesion (C) and a T11 lesion (D).
