Spondylolysis is a term to describe a stress fracture that occurs in the vertebrae of the lower spine. Vertebrae are the series of bones that make up your spine. Spondylolysis can result from excessive and repetitive forces during some sports.

Spondylolysis may not cause symptoms. It can cause pain that spreads throughout the lower back. Rest and back bracing can provide symptom relief. Spinal fusion surgery may be necessary if non-surgical treatments are ineffective or if your condition gets worse.


The lumbar area of your spine is located in your lower back. It forms the curve below your waist. Five large vertebrae make up the lumbar spine. Ligaments and muscles connect to the spinal column and provide stability and movement.

The back part of each vertebra arches to form the lamina. The lamina creates a roof-like cover over the back opening in each vertebra. The opening in the center of each vertebra forms the spinal canal. Your spinal cord and spinal nerves travel through the protective spinal canal.


A stress fracture in a vertebra is called spondylolysis. It may result from stress on the lower back during sports, such as gymnastics, weight lifting, and football. Some individuals are born with thin vertebral bones that are susceptible to this condition.


Spondylolysis may not cause symptoms. It can cause lower back pain. The pain may feel like a muscle strain that spreads across your lower back.


Your doctor can diagnose spondylolysis by reviewing your medical history and examining your back. You should tell your doctor about sports in which you participate or job duties that may affect your back. X-rays will be used to check for stress fractures and view your vertebral alignment. CT scans or MRI scans best indicate the fracture.


Discontinuing the activities that caused it may relieve the pain associated with spondylolysis. Anti-inflammatory medications and a back brace may help reduce pain. Physical therapy may be recommended to strengthen and stretch your back and abdominal muscles. You may be able to resume your activities gradually after your symptoms have subsided.


Surgery may be necessary if your symptoms do not improve or if your condition worsens. Spondylolysis can lead to spondylolisthesis, a condition where the vertebrae slip out of place. Spinal fusion surgery is used to permanently connect two or more vertebrae to stop movement and relieve pain. A bone graft or surgical hardware, such as screws and rods, are used to secure the vertebrae together. Spinal fusion surgery requires a short inpatient hospital stay followed by physical therapy.


Recovery from spinal fusion surgery can take several months. The length of your recovery depends on the extent of your condition and the type of surgery. Your doctor will let you know what to expect.
