Most lumbar isthmus fractures occur in patients due to direct external stimulation, resulting in fractures of the lumbar vertebrae or lumbar spondylolisthesis, resulting in lumbar isthmus fractures. Failure to treat a lumbar isthmic fracture can result in persistent, chronic pain in the lumbar spine, and in severe cases, can affect lumbar spine activities. If the pain is not severe and does not affect the patient’s normal life, special treatment may not be necessary. The patient can be instructed to reduce the amount of activity and the lumbar area can be fixed with a brace. If a patient has a lumbar isthmus fracture, the patient’s pain is severe and it affects the functional activities of the lumbar spine and the patient’s normal life, treatment should be taken. Because it is difficult to heal the fracture after lumbar isthmus fracture, it should be treated promptly.
