Cause of a Teenaged Crack in the Back

Some boys and girls involved in sports seem to be at risk for a certain kind of back problem. Ballerinas, football players, and weight lifters are the most likely to develop this problem. It's called spondylolysis. This is a term used to describe a defect, or crack, that forms in the bony ring on the back of the spinal column. The area affected is called the pars interarticularis, so doctors sometimes refer to this condition as a "pars defect."

It remains unknown what causes this defect to occur. Doctors think that repetitive stress on the bone is the most frequent cause. Others include weakness of the nearby soft tissue, a defect in the bone that is present at birth, and traumatic spine injuries.

In young athletes, this problem can be treated with temporary changes in activities. For example, the athlete is instructed to avoid overextending the back or repeating spine motions in any direction. Physical therapy treatment and pain medication can also be helpful.

Any young athlete who develops painful back symptoms should be seen by a doctor. Early treatment can help young people avoid serious injury later.
