Ivory epiphyses occurred more often in children in the lower socio\u2010economic class and children with hemoglobin AA. The cone epiphyses observed in Hb SS children were primarily a result of bone infarcts, while cones in children of other hemoglobin types appeared to be normal variants. The incidence of ivory epiphyses was higher in the Nigerian children than in American black children in the Ten\u2010State Nutrition Survey. The incidence of cone epiphyses was much lower than those reported for other normal populations.<\/jats:p>","DOI":"10.1002\/ajpa.1330510203","type":"journal-article","created":{"date-parts":[[2006,2,3]],"date-time":"2006-02-03T18:52:02Z","timestamp":1138992722000},"page":"155-161","source":"Crossref","is-referenced-by-count":4,"title":["The incidence of cone epiphyses and ivory epiphyses of the hand in Nigerian children"],"prefix":"10.1002","volume":"51","author":[{"given":"Helen A.","family":"Shaw","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Stanley P.","family":"Bohrer","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2005,5,2]]},"reference":[{"key":"e_1_2_1_2_1","doi-asserted-by":"publisher","DOI":"10.1136\/adc.47.254.519"},{"key":"e_1_2_1_3_1","first-page":"523","article-title":"Bone changes in hemoglobin SC disease","volume":"88","author":"Barton C.
