TERMINOLOGY
INTRODUCTION A compression fracture refers to the loss of bone
integrity and the subsequent loss of vertical height of one or more spinal
vertebrae. One of the most unstable types of compression fracture is the burst
fracture. This usually occurs as the result of trauma. Compression fractures represent the
most common type of fracture affecting the spine. A compression fracture may
occur if bone is unable to withstand excessive stress or if the bone is thin
and unable to sustain a normal load. The most common cause of a spinal
compression fracture is osteoporosis, a condition characterized by progressive
thinning of bone. Cancer weakens bones and makes them more susceptible to
fracture. PREVALENCE Approximately
700,000 cases of compression fractures occur each year in the United States due
to osteoporosis. |
