Which of the following disorders affects the lumbar vertebrae?

A. Scoliosis
B. Spinal stenosis
C. Ankylosing spondylitis
D. Degenerative disc disease

Answer :

Final answer:

Degenerative disc disease is the disorder that affects the lumbar vertebrae among the options provided. It is a condition where the intervertebral discs deteriorate over time and can cause pain and reduced mobility in the lumbar spine. Thus option d is correct.

Explanation:

The disorder that affects the lumbar vertebrae from the options provided is degenerative disc disease. This condition occurs over time when the discs within each vertebra begin to deteriorate, potentially affecting any part of the vertebra, intervertebral disk, and surrounding soft tissue. While it is true that degenerative disc disease can occur in any region of the spine, including the cervical and thoracic regions, it commonly affects the lumbar region, which is the lower part of the spine.

Other conditions such as scoliosis involve an abnormal lateral curvature, often with twisting of the vertebral column. It can affect different parts of the spine, including the lumbar region. However, degenerative disc disease specifically denotes the degeneration of the intervertebral discs, which can lead to pain and mobility issues in the lumbar spine. It's important to note that while conditions like spinal stenosis and ankylosing spondylitis can affect the lumbar spine as well, they are not limited to the lumbar region and have a broader impact.
