Indirect pars repair for pediatric isthmic spondylolysis: a case series

Isthmic spondylolysis (ISY) is a common cause of back pain in the pediatric population. Historically, non-operative treatments have had a very high success rate. The purpose of this study was to review the mid-term results of an indirect pars repair technique on reducing the visual analog score for pain (VAS), spondylolysis defect healing, complication rates and rates of return to pre-surgery activity level in pediatric patients who failed conservative care for ISY. A retrospective review of all pediatric patients (
