What condition describes the forward displacement of lumbar vertebrae?

• A. Spondylolisthesis
• B. Stenosis
• C. Kyphosis
• D. Lordosis

Answer: (A)

The condition that describes the forward displacement of lumbar vertebrae is known as spondylolisthesis. This condition occurs when one of the vertebrae slips forward over the vertebra below it, typically as a result of degenerative changes, a fracture, or congenital conditions. Spondylolisthesis can lead to pain, nerve compression, and other complications due to the misalignment of the spine. Other conditions mentioned, such as stenosis, involve the narrowing of the spinal canal, which can lead to pressure on the spinal cord and nerves, but does not specifically pertain to the forward movement of vertebrae. Kyphosis refers to an exaggerated forward curvature of the spine, often seen in the thoracic region, and is not characterized by the forward displacement of lumbar vertebrae. Lordosis describes an exaggerated inward curvature of the lumbar spine, which neither involves the displacement nor specifically indicates a slippage of the vertebrae. Understanding these distinctions is essential for correctly identifying spinal conditions and their implications for patient care.
