A patient presented with neck pain and rigidity, which gets relieved after bathing in hot water and also after exercise. The cervical X-ray is shown below. What is the likely diagnosis?
Ans: A. Spondylolisthesis
Given X-ray showing a forward displacement of the vertebrae on the lower one, suggestive of spondylolisthesis.
- Means forward translation of one segment of the spine upon another.
- The shift is nearly always between L4 and L5, or between L5 and the sacrum.
- Normal discs, laminae, and facets constitute a locking mechanism that prevents each vertebra from moving forwards on the one below.
- Forward shift (or slip) occurs only when this mechanism has failed.
