The costoclavicular ligament, also known as the rhomboid ligament or Halsted's ligament, is a ligament of the shoulder girdle.It is short, flat, and rhomboid in form. It is the major stabilizing factor of the sternoclavicular joint and is the axis of movement of the joint, especially during elevation of the clavicle.
On the medial part of the clavicle is a broad rough surface, the costal tuberosity (impression for costoclavicular ligament), rather more than 2 cm. in length, for the attachment of the costoclavicular ligament.
The costoclavicular ligament is the main limitation to movement, and therefore the main stabilizer of the joint.

On the medial part of the clavicle is a broad rough surface, the costal tuberosity (rhomboid impression), rather more than 2 cm. in length, for the attachment of the costoclavicular ligament. The rest of this surface is occupied by a groove , which gives attachment to the Subclavius ; the coracoclavicular fascia , which splits to enclose the ...
Costoclavicular syndrome (narrowing between the clavicle and the first rib) – diagnosed with the costoclavicular maneuver. Some people are born with an extra incomplete and very small rib above their first rib, which protrudes out into the superior thoracic outlet space.
The coracoclavicular ligament connects the clavicle to the coracoid process of the scapula. [1] It is not part of the acromioclavicular joint articulation, but is usually described with it, since it keeps the clavicle in contact with the acromion. It consists of two fasciculi, the trapezoid ligament in front, and the conoid ligament behind. [2]

The anterior surface is convex, and looks forward and upward: that of the first gives attachment to the costoclavicular ligament and the subclavius muscle; those of the first six or seven at their sternal ends, to the pectoralis major. The others are covered by, and give partial attachment to, some of the flat muscles of the abdomen.
