The incidence of corns, calluses, warts, ingrown toenails, bunions, hallux rigidus, hammer toes, cavus, and pes planus were correlated with age, sex, race, and demographic background, along with the incidence of surgery, conservative treatment, or no treatment. The extrapolated data indicated that 40% of the population have foot problems, of which 12% had surgery and 7% have been untreated.<\/jats:p>","DOI":"10.1177\/107110078000100104","type":"journal-article","created":{"date-parts":[[2013,3,3]],"date-time":"2013-03-03T03:24:58Z","timestamp":1362281098000},"page":"8-10","source":"Crossref","is-referenced-by-count":170,"title":["Epidemiological Survey of Foot Problems in the Continental United States: 1978\u20131979"],"prefix":"10.1177","volume":"1","author":[{"given":"Nathaniel","family":"Gould","sequence":"first","affiliation":[{"name":"Department of Orthopaedic Surgery, University of Vermont College of Medicine, Burlington, Vermont 05405"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"William","family":"Schneider","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic Surgery, University of Vermont College of Medicine, Burlington, Vermont 05405"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Takamara","family":"Ashikaga","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic Surgery, University of Vermont College of Medicine, Burlington, Vermont 05405"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[1980,7,1]]},"reference":[{"key":"bibr1-107110078000100104","volume-title":"Characteristics of Population U.S.A., Summary, Part I, Section I, Bureau of the Census.","year":"1973"}],"container-title":["Foot &amp; Ankle"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.1177\/107110078000100104","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/journals.sagepub.com\/doi\/full-xml\/10.1177\/107110078000100104","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.1177\/107110078000100104","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,4,28]],"date-time":"2026-04-28T21:16:48Z","timestamp":1777411008000},"score":1,"resource":{"primary":{"URL":"https:\/\/journals.sagepub.com\/doi\/10.1177\/107110078000100104"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[1980,7]]},"references-count":1,"journal-issue":{"issue":"1","published-print":{"date-parts":[[1980,7]]}},"alternative-id":["10.1177\/107110078000100104"],"URL":"https:\/\/doi.org\/10.1177\/107110078000100104","relation":{},"ISSN":["0198-0211"],"issn-type":[{"value":"0198-0211","type":"print"}],"subject":[],"published":{"date-parts":[[1980,7]]}}}
