Therefore, the German surgeon C.W. Streubel, in 1847, called it Adamscher Knochenbogen (Adams\u2019 arch). Due to misspelling, this term was gradually changed to Adambogen, and at the turn of twentieth century, it was commonly used primarily in the German literature. Then, it fell into oblivion and its \u201crenaissance\u201d came as late as during the 1960s, again in the German literature, in connection with operative treatment of trochanteric fractures.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Conclusions<\/jats:title>\n                <jats:p>However, under the influence of the English literature, it has been replaced by the term calcar femorale (femoral calcar), used ever since. The term Adams\u2019 arch should be reserved for the thickened medial cortex of the proximal femur, while the term calcar femorale (femoral calcar) should be used for the vertical plate arising from the medial cortex close below the lesser trochanter.<\/jats:p>\n              <\/jats:sec>","DOI":"10.1007\/s00264-023-05764-3","type":"journal-article","created":{"date-parts":[[2023,3,16]],"date-time":"2023-03-16T06:33:50Z","timestamp":1678948430000},"page":"1871-1877","update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":7,"title":["Internal architecture of the proximal femur: calcar femorale or Adams\u2019 arch?"],"prefix":"10.1007","volume":"47","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-2228-1443","authenticated-orcid":false,"given":"Jan","family":"Barton\u00ed\u010dek","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4801-1780","authenticated-orcid":false,"given":"Jan","family":"Alt","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6300-395X","authenticated-orcid":false,"given":"Ond\u0159ej","family":"Na\u0148ka","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"297","published-online":{"date-parts":[[2023,3,16]]},"reference":[{"key":"5764_CR1","doi-asserted-by":"crossref","unstructured":"Harty M (1957) The calcar femorale and the femoral neck.
