Spinal fracture can occur anywhere along the spine. Sixty – seventy percent occur in the thorax and lumbar spine (mid back + low back) region (e.g. T10, T11, T12) and 20 – 30 % in upper back spine. Five to ten percent occur in the cervical (neck) region.
When more pressure is put on a bone than it can stand, it will break. The most common type of spinal fracture is a vertebral body (like lumbar vertebrae) compression fracture. Sudden downward force destroys and collapses the body of the vertebrae. If the force is great enough, it may send bone fragments into the spinal canal, called a burst fracture.
Osteoporosis & Spinal Fracture | compression fracture
A spinal fracture due to osteoporosis (weak bones or brittle bones) is commonly referred to as a compression fracture, but can also be called a vertebral fracture, osteoporotic fracture, or wedge fracture. People affected by osteoporosis and certain forms of cancer with poor bone health are prone to vertebral compression fractures. The fracture appears as a wedge-shaped collapse of the vertebra. The front of the bone (vertebra) collapses and back side of the same bone remain undamaged. Multiple fractures can cause a forward hunch of the spine called kyphosis. As far as the back of the fractured bone (vertebra) is safe, spine initially remains stable but needs urgent intervention for future stability and safety as well.
Osteoporosis or even osteopenia causes bones to become thin and more brittle and weak. The thinning bones can collapse during normal activity, leading to a spinal fracture. Spinal fractures due to osteoporosis often occur while doing something that causes relatively minor injury to the spine.
