The anatomist's vade mecum : a system of human anatomy . s of the sterno-clavicular articulation are,a gliding movement of the fibro-cartilage, with the clavicle, upon thearticular surface of the sternum, in the direction, forwards, backwards,upwards, and downwards; and circumduction. This articulation isthe centre of the movements of the shoulder. It is the rupture of the rhomboid ligament in dislocation of thesternal end of the clavicle that gives rise to the deformity peculiar tothis accident. The interarticular fibro-cartilage is nearly circular in form, andthicker at the edges than in the centre. It is attached above, to theclavicle; below, to the cartilage of the first rib; and throughout therest of its circumference to the anterior and posterior sterno-clavicular 136 SCAPULO-CLAVICULAR LIGAMENTS. ligaments. It di^ddes the joint into two cavities, which are lined bydistinct synovial membranes. This cartilage is sometimes piercedthrough its centre, and not unfrequently deficient, to a greater or lessextent, at its lower part. Fig. 65.*. 2. Scapulo-clavicular ArUctiJation.—The ligaments of the scapularend of the clavicle are, the Superior acromio-clavicular,Inferior acromio-clavicular,Coraco-clavicular {trapezoid and conoid), Interarticular fibro-cartilage, Two synovial membranes. The superior acromio-clavicular ligameni is a moderately thick jjlaneof fibres passing between the extremity of the clavicle and the acromion,upon the upper surface of the joint. The inferior acromio-clavicidar ligament is a thin plane situatedupon the under surface. These two ligaments are continuous witheach other in front and behind, and form a complete capsule aroundthe joint. The coraco-clavicidar ligament {trapezoid, conoid) is a thick fasci-culus of ligamentous fibres, passing obliquely between the base of thecoracoid process and the under surface of the clavicle, and holding the end of the cla^icle in firm connection with the scapula. When seenfrom before, it has a quadrilate
