Which test is specifically performed to identify medial disc herniation?

• A. Bragard Sign
• B. Bowstring Sign
• C. Lindner Sign
• D. Well Leg Raise

Answer: (D)

The Well Leg Raise test is specifically utilized to identify issues related to nerve root involvement due to a herniated disc, particularly in the lumbar region. When a patient experiences pain in the leg that is raised, it indicates that the sciatic nerve may be affected by a herniation, often on the opposite side of the pain. This phenomenon occurs because raising the leg tensions the lumbar spine and can exacerbate any existing nerve root irritation or compression. In the context of medial disc herniation, this test is particularly relevant as medial herniations are known to affect the nerve roots more significantly, leading to symptoms on the opposite side when the contralateral leg is elevated. Therefore, a positive result on the Well Leg Raise suggests the presence of a herniation that is pressing on nerve roots, confirming its utility in this specific assessment scenario.
