Spondylolysis and spondylolisthesis are common diagnoses made in the athlete suffering from persistent back pain. Although the etiology of this continuum of conditions is uncertain, genetic predisposition and repetitive trauma have been strongly implicated. Sports in which participants are subjected to repetitive hyperextension across the lumbar spine pose a risk for such injuries. Football lineman, oarsmen, dancers, and gymnasts show high rates of these conditions. Treating the athlete with spondylolysis and/or spondylolisthesis can be a challenge. An inherent drive for return to competition, pressure from coaches and family, and obligations to the team can confound decision making on both the part of the patient and the treating physician. Although this motivation for prompt return to sports must certainly be considered, a safe return to competition is paramount.
