1 A spiral fracture happens when the break spirals around the bone, which can happen if the bone is twisted. 2  A compression fracture happens when vertebrae in the spinal column are pushed together in an accident or because of osteoporosis.
Compression fracture of the vertebral body is common, especially in older adults. Vertebral compression fractures usually are caused by osteoporosis, and range from mild to severe.he applied force usually causes the anterior part of the vertebral body to crush, forming an anterior wedge fracture (Figure 1) . The middle column remains intact and may act as a hinge. This results in loss of anterior height of the vertebra while the posterior height remains unchanged.
