What does the obturator sign indicate when it shows pain in the lower abdomen or thigh?

• A. Hernia
• B. Pneumonia
• C. Appendicitis
• D. Kidney Stones

Answer: (C)

The obturator sign is a clinical examination finding used to evaluate for appendicitis, particularly when the appendix is located in an atypical position, such as in the pelvis. When the obturator sign is positive, it indicates irritation of the obturator internus muscle, which can occur due to inflammation or infection associated with the appendix. During the physical examination, this sign is elicited by flexing and internally rotating the hip, which may reproduce pain in the lower abdomen or thigh. This specific pain pattern correlates with appendicitis because inflammation can affect the surrounding structures, including the muscles and nerves in the region. The other options do not align with the presentation of the obturator sign. For example, while hernias can cause abdominal pain, they typically present with a different set of symptoms and examination findings. Pneumonia and kidney stones also have distinct clinical presentations that are not associated with the obturator sign. Thus, recognizing the obturator sign as an indicator of appendicitis is crucial in clinical practice, as it aids in swiftly diagnosing this condition, which often requires urgent surgical intervention.
