In the provided example, which rib is involved?

• A. Rib 2
• B. Rib 3
• C. Rib 1
• D. Rib 4

Answer: (A)

Focus on locating the rib by hand landmarks. The second rib sits at the level of the sternal angle (the junction between the manubrium and the body of the sternum) and is the first true rib that articulates with the sternum. In many rib dysfunction scenarios, findings described at or just beneath the clavicle point to this level, making the second rib the involved one. The first rib is very near the clavicle but has a different articulation pattern, and ribs three and four lie lower, aligning with different chest-wall landmarks. So the described site best matches the second rib.
