Movements at the human shoulder girdle are the result of complex interplay of glenohumeral, acromioclavicular, sternoclavicular and scapulothoracic articulations. Clavicle apart from articulating with the scapula and sternum is also connected with first rib by costoclavicular ligament and with coracoid process by coracoclavicular ligament. At times the area of attachment of these ligaments on clavicle, first rib and scapula show faceted apophysis suggesting the presence of additional diarthrodial articulations. Costoclavicular joint exists between clavicle and first rib and coracoclavicular joint between clavicle and coracoids process. Both these joints are described in the literature, but the concurrent occurrence of them in the same bone has not been reported yet. We found two clavicles, one of right and other of left side, both of them showed faceted apophysis for costoclavicular and coracoclavicular joint simultaneously, which is rare phenomenon. Los movimientos de la cintura escapular humana son el resultado de la interacci車n compleja de las articulaciones glenohumeral, acromioclavicular, esternoclavicular y escapulotor芍cica. La clav赤cula, aparte de la articulaci車n con la esc芍pula y el estern車n tambi谷n est芍 conectada con la primera costilla por el ligamento costoclavicular y con el proceso coracoides por el ligamento coracoclavicular. A veces la zona de uni車n de estos ligamentos de la clav赤cula, la primera costilla y la esc芍pula muestran procesos facetarios que sugieren la presencia de nuevas articulaciones diartrodiales. La articulaci車n costoclavicular existe entre la primera costilla y la clav赤cula y la articulaci車n coracoclavicular entre la clav赤cula y proceso coracoides. Ambas articulaciones est芍n descritas en la literatura, pero la aparici車n simult芍nea de ellas en el mismo hueso no se ha informado a迆n. Se encontraron dos clav赤culas, uno del lado derecho y otra del lado izquierdo, las dos presentaron procesos facetarios para las articulaciones costoclavicular y coracoclavicular simult芍neamente, lo cual es un fen車meno raro.
