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.
A compression fracture is nearly always a serious injury, because the spinal cord is near each of the vertebrae and is at risk whenever they shift. A compression fracture is most likely to be caused by serious trauma to the spine, particularly in the case of falling from an extreme height. Because of the force necessary to cause compression fractures, they often occur in tandem with other injuries, including damage to the spinal cord and severe ligament damage.
