In case of appendicitis, if the pain is exacerbated on medial rotation of the thigh, the position of appendix is in
**Core Concept**
The position of the appendix is variable, but it is most commonly located in the retrocecal position, near the junction of the small and large intestines. In this location, the appendix is susceptible to irritation and inflammation due to its proximity to the cecum and the ileocecal valve.
**Why the Correct Answer is Right**
When the appendix is located in the retrocecal position, medial rotation of the thigh can cause the appendix to become irritated due to the increased pressure and tension on the cecum and the surrounding tissues. This is because the appendix is located in close proximity to the iliac vessels and the psoas muscle, which can become compressed during medial rotation of the thigh.
**Why Each Wrong Option is Incorrect**
**Option A:** This option is not relevant to the question, as it does not describe a position of the appendix that would be affected by medial rotation of the thigh.
**Option B:** This option is incorrect because the McBurney's point is not directly related to the position of the appendix in relation to medial rotation of the thigh.
**Option C:** This option is incorrect because the pelvic position of the appendix would not be exacerbated by medial rotation of the thigh.
**Clinical Pearl / High-Yield Fact**
It's essential to remember that the position of the appendix can vary, and its location can be determined by the patient's symptoms and physical examination. In this case, medial rotation of the thigh can be used as a diagnostic clue to determine the position of the appendix.
**Correct Answer: C. Pelvic position**
