The incidence of an articular facet on the conoid tubercle of the clavicle indicating the presence of a coracoclavicular joint was studied in paired clavicles obtained from 1,000 adult subjects aged 18 to 95 years (748 males, 252 females), and 75 children (45 males, 30 females) of known age on whom a medicolegal postmortem had been performed by the second author during 1972-90. The subjects were inhabitants of northwest India. In addition, paired clavicles from 50 neonates and 35 fetuses were also examined. The facet was absent in the fetuses, neonates, and young children. The youngest clavicle showing the facet was from a girl of 13 years, in which it was present bilaterally. In adults the incidence of the facet was 10.1% (bilateral 5.7%, unilateral 4.4%) in males and 8.3% (bilateral 3.6%, unilateral 4.8%) in females. Absence of the facet in the fetuses, neonates, and young children shows that it is not a congenital anomaly.
在1972年至1990年间，第二作者对1000名年龄在18至95岁的成年受试者（748名男性，252名女性）以及75名已知年龄的儿童（45名男性，30名女性）进行法医尸检时获取的成对锁骨进行研究，以探讨锁骨锥状结节上关节小面的发生率，该关节小面表明存在喙锁关节。这些受试者是印度西北部居民。此外，还检查了50例新生儿和35例胎儿的成对锁骨。胎儿、新生儿和幼儿均无此关节小面。出现该关节小面的最年轻锁骨来自一名13岁女孩，且双侧均有。在成年人中，男性该关节小面的发生率为10.1%（双侧5.7%，单侧4.4%），女性为8.3%（双侧3.6%，单侧4.8%）。胎儿、新生儿和幼儿不存在该关节小面，表明它并非先天性异常。
