Frequently Asked Questions
What is a pars stress fracture?
A pars stress fracture is a small crack in part of a vertebra in the lower back. It is common in young athletes who repeatedly extend or rotate the spine. It is also called spondylolysis.
What causes a pars stress fracture?
It is caused by repetitive stress on the lower spine, especially extension and rotation. Sports like gymnastics, football, dance, wrestling, and baseball can increase risk. Growth spurts and high training volume may also contribute.
What are the symptoms?
Symptoms include lower back pain that worsens with activity, especially bending backward. Pain usually improves with rest. Some athletes have tight hamstrings or limited spine motion.
How is a pars stress fracture treated?
Treatment usually includes rest from painful sports, physical therapy, and gradual return to activity. Bracing may be used in selected cases. Early diagnosis helps prevent progression.
When can I return to sports?
Return often takes several months depending on healing and symptoms. Athletes should be pain-free with extension, rotation, and sport-specific movements before returning. A gradual progression is important.
