A transverse process fracture is a break in 1 or more transverse process. These are wing-like bones on the right and left side of each vertebra in the spine.

These fractures are caused by trauma from:
- Car, motorcycle, or pedestrian accidents
- Severe and sudden twisting or bending
- Severe blows to the back and spine
- Violence, such as a gunshot
Older adults are at higher risk. Things that may increase the chance of a spinous process fracture are:
- Having health problems that weaken bones, such as osteoporosis
- Low muscle mass
- Playing sports that involve sudden twists and turns or extreme contact
- Not wearing a seatbelt
- Being around violence
These fractures can happen at any place in the spinal column. They may cause:
- Severe pain that may be worse when moving
- Swelling and bruising
- Numbness, tingling, or weak muscles
- Problems moving the injured part of the spine
- Loss of bladder or bowel control
The doctor will ask about your symptoms and health history. You will also be asked how the injury happened. A physical exam will be done. It will also look for nerve damage.
Images may be taken to look at your spine. This can be done with:
Treatment will depend on how severe the injury is. It may take up to 6 weeks to heal.
The spine will need to be supported as it heals. A back brace can help keep a minor fracture in place while it heals.
People with a severe fracture may need surgery. Screws, rods, wires, or cages will be used to reconnect bone pieces and hold them in place.
Rehabilitation may be needed. It will include exercises to keep muscles strong and help with range of motion.
Most fractures happen due to accidents. Healthy bones and muscles may prevent injury. This may be done through diet and exercise.
