Younger patients have a higher risk for progression of isthmic or congenital spondylolisthesis. Serial radiographic studies (standing lateral films only) should be performed every 6 months to follow these patients. Progression rarely occurs after adolescence. Patients with a unilateral pars defect may be prone to developing a contralateral pars defect with extension stress. Patients with degenerative spondylolisthesis are often older and have coexisting medical issues that must be taken into consideration when deciding appropriate treatment.
