Spondylolisthesis is a spinal condition in which one vertebra in the spine slips out of its normal position onto the vertebra below it. This displacement can cause compression of the spinal nerves and lead to symptoms such as back pain, leg pain, and muscle weakness. There are several types of spondylolisthesis, including: Congenital spondylolisthesis: This is a rare condition that is present at birth and results from an abnormal formation of the spine. Isthmic spondylolisthesis: This type of spondylolisthesis is caused by a defect in a part of the vertebra known as the pars interarticularis. Degenerative spondylolisthesis: This is the most common type of spondylolisthesis and is usually caused by age-related wear and tear on the spine. Traumatic spondylolisthesis: This occurs when a vertebra is displaced due to a traumatic injury, such as a car accident or a fall. Treatment options for spondylolisthesis depend on the severity of the condition and the degree of displacement. Mild cases may be treated with physical therapy and pain management techniques, while more severe cases may require surgery to realign the vertebrae and decompress the spinal nerves.
