Which ligament is located on the anterior aspect, connecting the sternum to the clavicle?

• A. Dorsal Ulnocarpal Ligament
• B. Collateral Metacarpophalangeal Ligament
• C. Pubofemoral Ligament
• D. Anterior Sternoclavicular Ligament

Answer: (D)

The key idea is understanding the ligaments that stabilize the sternoclavicular joint from the front. The ligament sitting on the anterior aspect of this joint, connecting the sternum to the clavicle, is the anterior sternoclavicular ligament. It anchors the clavicle to the manubrium and reinforces the joint capsule on the front, helping resist forward (anterior) movement of the clavicle during shoulder actions. The other options are ligaments from different joints—wrist, finger joints, and hip—so they don’t connect the sternum to the clavicle or lie at the front of the sternoclavicular joint.
