Trendelenburg test is positive in –
**Trendelenburg Test**
**Core Concept**
The Trendelenburg test is a clinical examination used to assess the integrity of the inguinal ligament and its associated structures, particularly in the context of femoral hernias. It involves elevating the patient's affected leg to assess for a bulge in the inguinal canal.
**Why the Correct Answer is Right**
When a femoral hernia is present, the Trendelenburg test becomes positive due to the hernia bulging into the inguinal canal when the patient's affected leg is elevated. This is because the femoral hernia is located below the inguinal ligament, and when the leg is lifted, the increased intra-abdominal pressure causes the hernia to protrude. The test is performed by asking the patient to stand with their affected leg elevated, and a positive result is indicated by a bulge in the inguinal canal.
**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect because the Trendelenburg test is not primarily used to diagnose inguinal hernias, but rather femoral hernias.
**Option B:** This option is incorrect because the Trendelenburg test does not involve applying pressure to the groin area; instead, it relies on the patient's position and the presence of a bulge.
**Option C:** This option is incorrect because the Trendelenburg test is not a diagnostic tool for abdominal masses or other abdominal pathology.
**Clinical Pearl / High-Yield Fact**
A key point to remember is that the Trendelenburg test is a useful clinical examination for diagnosing femoral hernias, but it may not be as sensitive for other types of inguinal hernias.
**Correct Answer: D. Femoral hernia.**
