The line for the ligament that looks like a trapeze.

• A. Conoid ligament
• B. Trapezoid line
• C. Fovea for ligament of head of femur
• D. Facet for plantar calcaneonavicular ligament

Answer: (B)

This item focuses on clavicle landmarks for the coracoclavicular ligaments. The coracoclavicular ligament has two parts: the conoid and the trapezoid. The trapezoid part attaches along a specific line on the clavicle called the trapezoid line, which marks its attachment site. So, the line for the ligament that looks like a trapeze is the trapezoid line. For context, the conoid ligament attaches to the conoid tubercle on the inferior clavicle, a different feature from the trapezoid line. Other options refer to structures on different bones: the fovea for the ligament of the head of the femur is on the femur head, not the clavicle, and the facet for the plantar calcaneonavicular ligament is on the calcaneus.
