Description
Summary:The present study describes two unusual and large bony processes which were found at the acromial end of a dried human clavicle, due to their rarity and impressive appearance. At the anterior border of right dried clavicle we noticed a quadrilateral process having an articular surface at its free end, which probably articulated with the humeral head. At the posterior part of the clavicle inferior surface there was a large conoid process, which replaced the conoid tubercle. The conoid process did not appear any articular surface at its free end to be considered as a coracoclavicular joint. Although the conoid process of the clavicle may be congenital and usually articulates with the coracoid process of the scapula, in our case the conoid process was acquired and presented a rough and slightly sharp tip, without any joint surface. It was very interesting that the quadrilateral process found at the anterior border of the same clavicle was probably forming an accessory joint between the clavicle and the humeral head.
