What does the lesser trochanter correspond to in Chapman’s reflex?

1. Rectum

2. Appendix

3. Kidneys

4. Adrenals

The correct answer is: Appendix

The lesser trochanter in Chapman’s reflex is associated with the appendix. In the context of somatic dysfunction and visceral pathology, Chapman’s points serve as specific reflexive areas situated on the body that correlate with particular organs. The lesser trochanter, being anatomically located on the femur and adjacent to the iliopsoas muscle, corresponds to the appendix reflex point, which can manifest as tenderness in that area when there is a dysfunction in the appendix. When assessing Chapman’s points, it is essential to recognize their clinical relevance in diagnosing and managing visceral disorders. Tenderness or altered findings at the lesser trochanter can guide a clinician toward considering appendiceal issues, such as appendicitis or other appendiceal pathologies, during a physical examination.
