What It Is

A transverse process fracture is a break in one of the small bony projections on the side of a vertebra. On its own it does not usually affect the stability of the spine and does not need surgery (AAOS, n.d.). They can occur in any vertebra, but the middle and lower back are common areas. However, these fractures are often caused by high-energy accidents, such as falling from a height or a car accident, and can come with other serious injuries, including injuries to organs in the abdomen, which doctors need to rule out (Agrawal, Srivastava and Kakani, 2009; Kaya, 2024).

Older people whose bones are weakened by osteoporosis can fracture a vertebra in lower-impact events (AAOS, n.d.).

Transverse process fractures result from rotation or extreme sideways bending (AAOS, n.d.).

Many people call the fracture a "broken back" or "fractured vertebra", which technically it is, as part of the vertebra has broken. However, an isolated transverse process fracture does not involve the spinal cord, so it is very unlikely to cause nerve problems. If the trauma is large enough and other vertebrae are also fractured or dislocated, spinal cord injury is possible.

Transverse Process Fracture Anatomy

The spine is made up of 33 small bones, called vertebrae, stacked on top of each other (AAOS, n.d.). Ligaments, nerves, muscles and intervertebral discs are also part of the spine.

The vertebrae form a canal that protects the spinal cord. The spine has three main sections that create its natural curves: the neck (cervical), the chest area or mid-back (thoracic) and the lower back (lumbar).

Spinal nerves branch out from the spinal cord through openings between the vertebrae to carry messages between the brain and the muscles.

The transverse process is a projection of bone on the side of the vertebra; there is one on each side. The projection at the back of the vertebra is called the spinous process.
