Spondylolisthesis in the Young Athlete.

In brief Young athletes with persistent unexplained low-back pain or tight hamstrings should be evaluated for possible spondylolisthesis. Although the physical examination is often unrevealing, hamstring tightness is a common finding in symptomatic patients. Anteroposterior, lateral, and possibly right and left oblique x-rays of the lumbosacral spine will suggest the diagnosis.
