Tailbone trauma is an injury to the small bone at the lower tip of the spine.
Backward falls onto a hard surface, such as a slippery floor or ice, are the most common cause of this injury.
- Bruising on the lower part of the spine
- Pain when sitting or putting pressure on the tailbone
For tailbone trauma when no spinal cord injury is suspected:
- Relieve pressure on the tailbone by sitting on an inflatable rubber ring or cushions.
- Take acetaminophen for pain.
- Take a stool softener to avoid constipation.
If you suspect injury to the neck or spine, DO NOT attempt to move the person.
DO NOT attempt to move the person if you think there may be injury to the spinal cord.
When to Contact a Medical Professional
Call for immediate medical help if:
- Spinal cord injury is suspected
- The person can't move
- Pain is severe
Keys to preventing tailbone trauma include:
- DO NOT run on slippery surfaces, such as around a swimming pool.
- Dress in shoes with good tread or slip-resistant soles, especially in snow or on ice.
