BACKGROUND/AIM: 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.
DESCRIPTION OF THE CASE
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.
CONCLUSION
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.
背景/目的：本研究描述了在一具干燥人锁骨肩峰端发现的两个不同寻常的大骨突，因其罕见性和引人注目的外观。
病例描述
在右侧干燥锁骨的前缘，我们注意到一个四边形骨突，其游离端有一个关节面，可能与肱骨头相关节。在锁骨下表面的后部有一个大的圆锥状骨突，它取代了圆锥结节。圆锥状骨突的游离端未出现任何被视为喙锁关节的关节面。
结论
虽然锁骨的圆锥状骨突可能是先天性的，通常与肩胛骨的喙突相关节，但在我们的病例中，圆锥状骨突是后天形成的，其尖端粗糙且稍尖，没有任何关节面。非常有趣的是，在同一锁骨前缘发现的四边形骨突可能在锁骨和肱骨头之间形成了一个副关节。
