Spondylolysis is a defect or fracture in the pars interarticularis of the lumbar vertebrae. It is most commonly located at the L5 vertebra in the lower back but can also be located at other levels of the spine. Spondylolysis can occur as a result of overuse or injury, as well as from a congenital predisposition, and can be a cause of back pain.
The pars repair procedure is a minimally invasive and is utilized when your child has persistent symptoms over 6 months despite strict activity modification as directed by a health care provider. This procedure has the advantage of motion preservation in the back when compared to a spine fusion.
Your surgeon will be able to discuss what procedure is best for your child based on the quality of the pars defect. The goal of the procedure is to treat the pain and return your child to their daily activity.
