Simulated weightbearing CT scans and plain radiographs of 37 symptomatic flat feet were examined in this study. The degree of arthritic degeneration was assessed in the major hindfoot and midfoot joints, and the location of deformity was studied along the medial column of the arch. Moderate to severe degeneration was seen in about one-third of talonavicular, subtalar, and calcaneocuboid joints. The medial column of the arch collapsed through the talonavicular joint in some feet, through the medial naviculocuneiform joint in others, but rarely through both. First tarsometatarsal joint subluxation was a frequent finding as well. In this small series, neither the degree of degenerative arthritis nor the amount of joint deformity was seen to correlate with patient age. Furthermore, no correlation was observed between foot deformity and joint degeneration.<\/jats:p>","DOI":"10.1177\/107110070302400704","type":"journal-article","created":{"date-parts":[[2015,11,24]],"date-time":"2015-11-24T21:24:44Z","timestamp":1448400284000},"page":"530-534","source":"Crossref","is-referenced-by-count":93,"title":["Deformity and Degeneration in the Hindfoot and Midfoot Joints of the Adult Acquired Flatfoot"],"prefix":"10.1177","volume":"24","author":[{"given":"Justin","family":"Greisberg","sequence":"first","affiliation":[{"name":"Assistant Professor, Department of Orthopaedics, Columbia University, New York, NY"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"suffix":"Jr.","given":"Sigvard T.","family":"Hansen","sequence":"additional","affiliation":[{"name":"Professor, Department of Orthopaedics, University of Washington, Seattle, WA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Bruce","family":"Sangeorzan","sequence":"additional","affiliation":[{"name":"Professor, Department of Orthopaedics, University of Washington, Seattle, WA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2003,7]]},"reference":[{"key":"e_1_3_1_2_2","doi-asserted-by":"publisher","DOI":"10.2106\/00004623-199908000-00010"},{"key":"e_1_3_1_3_2","doi-asserted-by":"publisher","DOI":"10.1177\/107110079701801105"},{"key":"e_1_3_1_4_2","doi-asserted-by":"publisher","DOI":"10.1177\/107110079701800208"},{"key":"e_1_3_1_5_2","doi-asserted-by":"publisher","DOI":"10.1302\/0301-620X.77B3.7744923"},{"key":"e_1_3_1_6_2","doi-asserted-by":"publisher","DOI":"10.2106\/00004623-198668010-00012"},{"key":"e_1_3_1_7_2","doi-asserted-by":"publisher","DOI":"10.1177\/107110070102200802"},{"key":"e_1_3_1_8_2","volume-title":"Functional Reconstruction of the Foot and Ankle","author":"Hansen ST","year":"2000","unstructured":"Hansen ST: Functional Reconstruction of the Foot and Ankle, Philadelphia, Lippincott Williams & Wilkins, 2000."},{"key":"e_1_3_1_9_2","doi-asserted-by":"publisher","DOI":"10.1097\/00003086-199908000-00008"},{"key":"e_1_3_1_10_2","first-page":"46","article-title":"Radiographic criteria for epidemiologic studies of osteoarthritis","volume":"22","author":"Hart DJ","year":"1995","unstructured":"Hart DJ, Spector TD: Radiographic criteria for epidemiologic studies of osteoarthritis.
