Isthmic Spondylolisthesis, while normally affecting children, can manifest well into maturity. To learn more about this, search Dr. Anthony Leone’s Knowledge Center.
When one vertebral body shifts onto the one below it, this causes tiny fractures in the bone connecting the two joints. This fracture is caused by stress to the bone fragment. This fracture is most common in young patients and symptoms generally do not manifest until maturity. When the vertebral body shifts (as opposed to fractures), this is known as spondylolisthesis. Surprisingly enough, this phenomenon rarely leads to associated back pain in the patient.
