Volume and fat infiltration of spino-pelvic musculature in adults with spinal deformity

Figure 5 Magnetic resonance imaging samples (A: Lumbar area; B: Pelvis area; C: Limb area) of a 37-year-old female adult spinal deformity patient with a body mass index of 22 kg/m². This patient presents a sagittal deformity with hyperlordosis of the lumbar spine (pelvic incidence minus lumbar lordosis = -29°) and a thoraco-lumbar kyphosis of 45°. The analysis of the muscle quality revealed an 6.1% of fat infiltration on average.
