In tuberculosis of the spine, which is the most common site of involvement?
Show Hint
Pott's spine favours the lower thoracic to lumbar junction.

- Sacral
- Cervical
- Dorsolumbar
- Lumbosacral
Show Solution
The Correct Option is C
Solution and Explanation
Step 1: Spinal tuberculosis, also called Pott's spine, is the leading musculoskeletal site of tubercular infection, and it usually settles in the anterior vertebral body and paradiscal area.
Step 2: When the frequency of vertebral levels is ranked, the disease clusters around the dorsolumbar junction. The lower thoracic vertebrae take the top spot, with the lumbar vertebrae coming next, so the combined dorsolumbar zone represents the commonest location.
Step 3: Comparing the alternatives, the cervical region is an infrequent target, and the sacral and lumbosacral levels are likewise uncommon relative to the thoracolumbar predilection that defines this disease.
Step 4: The vertebral region most often struck by tuberculosis is therefore the dorsolumbar segment.
\[\boxed{\text{Dorsolumbar}}\]
