Early treatment can improve outcomes.

This problem is caused by doing repetitive tasks, such as flexing, extending, or rotating the lower back. This leads to trauma that happens over time.

Risk Factors

This problem is more common in young adults, especially those who do sports. It is also more common in men.

Other things that may raise the risk are:

  • Having other family members with this health problem
  • Playing sports, such as gymnastics, soccer, and basketball


Most people do not have symptoms. Others may have:

  • Low back pain
  • Pain that is worse with activity and better with rest
  • Muscle pain
  • Pain that spreads to the buttocks and the back of the thighs


The doctor will ask about your symptoms and health history. A physical exam will be done. It will focus on the back.

Images of the spine may be taken. This can be done with:


The goal of treatment is to manage symptoms and promote healing. Medicines will be given to ease pain. Other choices are:

  • Avoiding physical activities that put stress on the back
  • Wearing a brace to limit movement
  • Physical therapy to promote strength, flexibility, and range of motion

People who are not helped by these methods may need surgery. Choices are:

  • Spinal fusion to fuse two vertebrae together
  • Using a strong screw to hold the fracture together


There are no known guidelines to prevent this health problem.
