To study the time and mode of the development of the colliculus atlantis, the rate of its occurrence, the causes for its absence, and the radiological-clinical importance in the analysis of open-mouth-view radiographs.
Retrospective analysis of standardized radiographs of the cervical spine in more than 20,000 adults and 100 children. Study of 234 human skeletons of different ages and of 38 isolated adult atlases. Cadaveric dissection of 42 adults (age 48-87). Axial radiographs of isolated atlases and analysis of the bony structures of the colliculus atlantis.
The colliculus atlantis develops between age 10 and 13 years. It is always present after age 13 years. For the development of the colliculus atlantis a normal function of the craniocervical joints is necessary. In congenital dysmorphias of the craniocervical region with dysfunction of the craniocervical joints and in fractures of the dens axis before age 10 years with instable healing the colliculus atlantis is absent.
The colliculus atlantis is developed at age 13 years apart from some rare exceptions as mentioned. Changes of the site and the structure of the colliculus atlantis allow an early diagnosis of certain traumatically and inflammatory diseases of this region. Furthermore, it serves as an additional parameter in functional analysis of the craniocervical joints.
研究寰椎小丘的发育时间和方式、其出现率、缺如原因以及在开口位X线片分析中的放射学 - 临床意义。
对20000多名成人和100名儿童的颈椎标准X线片进行回顾性分析。研究234具不同年龄的人类骨骼和38个单独的成人寰椎标本。对42名成年人（年龄48 - 87岁）进行尸体解剖。对单独寰椎标本的轴向X线片及寰椎小丘的骨质结构进行分析。
寰椎小丘在10至13岁之间发育。13岁以后总是存在。寰椎小丘的发育需要颅颈关节的正常功能。在颅颈区域先天性畸形伴颅颈关节功能障碍以及10岁前齿状突骨折且愈合不稳定的情况下，寰椎小丘缺如。
除了上述一些罕见例外情况，寰椎小丘在13岁时发育。寰椎小丘的位置和结构变化有助于早期诊断该区域的某些创伤性和炎症性疾病。此外，它可作为颅颈关节功能分析中的一个附加参数。
