- Abnormal increase in thoracic curvature
- Caused by erosion of anterior part of 1+ vertebrae
- As erosion continues, vertebrae collapses, causing loss of height
Kyphosis (aka "humpback")
- Net demineralization of bonesĀ
- Caused by disruption of calcium deposition and reabsorption
- Bones become weak and brittle, causing them to be more likely to fracture
Osteoporosis
- Caused by abnormal increase in lumbar curvature
Lordosis ("hollow back")
- Abnormal lateral curvature (S-shaped) accompanied by rotation of vertebrae
- Spinous processes turn toward abdominal cavity
Scoliosis ("curved back")
