The conoid ligament is a narrow and strong band that connects the clavicle bone with the scapula bone. It helps to stabilize the acromioclavicular joint, which is a part of the shoulder joint. There are several synonyms for the conoid ligament, including the trapezoid ligament, the cono-trapezoid ligament, the coraco-clavicular ligament, and the coraco-acromial ligament. These ligaments play a vital role in maintaining the structural integrity of the shoulder joint and allowing for smooth movement of the arm. Understanding the different names for the conoid ligament can help in medical communication and research studies.
