Spondylolysis

October 26, 2016

Spondylolysis is a defect of a vertebra. More specifically, it is defined as a defect in the pars interarticularis of the vertebral arch. Often it occurs in the lowest of the lumbar vertebrae. It is often caused by a stress fracture of the bone, and is especially common in adolescents who overtrain in activities. It can also be an hereditary component, such as a tendency toward thin vertebral bones. Spondylolysis symptoms can include pain that leads to reduced mobility and inactivity. Nonsurgical treatment includes taking anti-inflammatory medication and physical therapy. When symptoms are not relieved with nonsurgical treatment, surgical intervention may be necessary.
