Our spine is made up of 31vertebrae, out of which 8 form cervical, 12 thoracic, 5 lumbar, 5 sacral, and 1 coccygeal nerve regions. The bones of our vertebral column are very strong yet due to excessive pressure, hard fall or weakening of bones due osteoporosis may cause vertebral fracture. When lumbar vertebrae bone collapses it is referred as lumbar compression fracture.
The lumbar vertebrae, attached with strong stabilizing muscles to spinal cord, are the largest and strongest of all vertebrae in the spine. Any physical injury, severe trauma, pathological changes and weakening of lumbar vertebrae are the most frequent causes of lumber compression fracture. Osteoporosis is the chief underlying cause of lumbar fractures among postmenopausal women.
