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.
Fractures caused by osteoporosis most often occur in the spine. These spinal fractures â called vertebral compression fractures â occur in nearly 700,000 patients each year. They are almost twice as common as other fractures typically linked to osteoporosis, such as broken hips and wrists. Not all vertebral compression fractures are due to osteoporosis. But when the disease is involved, a fracture is often a patient's first sign of a weakened skeleton from osteoporosis.
