A compression fracture of the spine is a type of fracture that occurs when the bones of the spine (vertebrae) become crushed or compressed. Compression fractures can be caused by a variety of factors, including osteoporosis (a condition that causes the bones to become weak and brittle), trauma, or tumors.
Symptoms of a compression fracture may include back pain, difficulty standing or walking, and a hunched posture. In severe cases, a compression fracture can cause the spine to become deformed, leading to a condition called kyphosis (a curvature of the spine that causes the back to become rounded).
