understanding of the congenital and acquired abnormalities described in the present paper.(A) Congenital Abnormalities(1) Coracoid Tubercle.-Innormal circumstances, the coracoclavicular ligaments arise from the elbow and part of the upper surface of the coracoid process and are inserted into the conoid tubercle and trapezoid line on the clavicle.The conoid tubercle, as a rule no more than a small rough surface eleva- tion, occasionally grows out in the direction of the coracoid process, in which case the term "coracoid tubercle", as proposed by Jaluvka (1956), would appear to be more appropriate.This author has shown how the process then "articulates" with the trapezoid ligament (a situation comparable to the articulation of the odontoid process of the axis with the transverse ligament of the atlas).The clavicular portion of the ligaments has atavistically maintained its bony structure, whereas the coracoid part has remained fibrous (Fig. 1).Fig. I.-Coracoid tubercle on clavicle; no reaction on coracoid process.
