## Surface Landmark: Inferior Angle of Scapula **Key Point:** The inferior angle of the scapula, when the arm is in anatomical position (hanging by the side), lies at the level of the **7th rib** or the T7 vertebra. ### Clinical Significance This is a crucial anatomical landmark used in: - **Counting ribs** — when ribs are difficult to palpate, the inferior scapular angle serves as a reference point - **Thoracentesis** — guides needle insertion for pleural fluid aspiration - **Physical examination** — assessing scapular position and movement - **Spinal procedures** — locating the T7 vertebral level for procedures like epidural injections ### Anatomical Variation The position can shift with arm movement: - **Arm at rest (anatomical position):** 7th rib - **Arm raised overhead:** scapula rotates upward, inferior angle moves laterally and superiorly - **Arm crossed over chest:** scapula protracts, inferior angle moves laterally **High-Yield:** The **7th rib** is the most commonly tested landmark for the inferior scapular angle in NEET PG. **Clinical Pearl:** When counting ribs from above, always start from the 1st rib (which is difficult to palpate) and count downward. The inferior scapular angle helps verify you have reached the 7th rib.
