Retrolisthesis
Retrolisthesis
Retrolisthesis (pronounced: retro-lis-thee-sis) is a medical condition characterized by the posterior displacement of a vertebral body in relation to the vertebra below.
Etymology
The term "retrolisthesis" is derived from the Latin roots "retro," meaning backward, and "listhesis," meaning slipping or sliding.
Definition
Retrolisthesis is a type of spondylolisthesis, which refers to the displacement of a vertebra. In the case of retrolisthesis, the displacement is backward, i.e., the upper vertebra moves towards the back relative to the vertebra below it. This condition can occur in any part of the spine, but it is most common in the cervical (neck) and lumbar (lower back) regions.
Symptoms
Symptoms of retrolisthesis can vary depending on the severity and location of the displacement. They may include back pain, stiffness, numbness, and in severe cases, loss of bladder or bowel control.
Diagnosis
Diagnosis of retrolisthesis typically involves a physical examination and imaging tests such as X-rays, MRI, or CT scan. The degree of displacement is usually measured in millimeters.
Treatment
Treatment for retrolisthesis depends on the severity of the condition. Non-surgical treatments may include physical therapy, pain medication, and lifestyle changes. In severe cases, surgery may be required to realign the vertebrae and relieve pressure on the spinal nerves.
