Which ligament is described as the ligament between the breastbone and collarbone, more to the front?

• A. Dorsal ulnocarpal ligament
• B. Collateral metacarpophalangeal ligaments
• C. Plantar calcaneonavicular ligament
• D. Anterior sternoclavicular ligament

Answer: (D)

The ligament between the breastbone (sternum) and the collarbone (clavicle) on the front is the anterior sternoclavicular ligament. It forms the front part of the sternoclavicular joint’s capsule, reinforcing it from the anterior side and helping prevent forward displacement of the clavicle during arm and shoulder movements. Other ligaments listed are located elsewhere—the dorsal ulnocarpal ligament is in the wrist, the collateral metacarpophalangeal ligaments are in the finger joints, and the plantar calcaneonavicular ligament is in the foot—so they don’t match the described location.
