**Core Concept**
The Pott's spine, also known as spinal tuberculosis, is a condition where the spine is affected by tuberculosis. Indicators of poor prognosis in Pott's spine are crucial for determining the treatment outcome.

**Why the Correct Answer is Right**

**Option A:** A healed vertebral lesion is not necessarily an indicator of poor prognosis. **Option D:** Short duration of symptoms may not be an indicator of poor prognosis. **Option E:** Acute onset may not be an indicator of poor prognosis.

**Clinical Pearl / High-Yield Fact**
A key point to remember is that the extent of spinal deformity and the degree of vertebral destruction are critical in determining the prognosis of Pott's spine.

**Correct Answer:** C. Kyphotic angle > 60°
