After metatarsal osteotomy, the actual first metatarsal shortening may appear magnified on standard x-rays. We investigated variations in metatarsal and intermetatarsal angle (IMA) in a cadaver model and variations of first metatarsal length following in vivo Chevron osteotomies.<\/jats:p>\n For skeletal models, changing the foot arch from pes planus to pes cavus changed the first metatarsal length by as much as 19%, whereas the measured IMA remained relatively unchanged. Pronation of the first metatarsal was found to alter the IMA (decreased for planus, increased for cavus). In vivo studies revealed a 3.2-fold difference when actual metatarsal length change following chevron osteotomy was correlated to corrected x-ray change in length (9.5% versus 2.9% P \u2264 .005).<\/jats:p>\n \n Previous investigators have evaluated hallux valgus deformities with emphasis on metatarsal lengths and IMAs to determine choices of procedure.\n 3 , 5 , 10<\/jats:sup>\n Based on the results of this study, treatment plans and further evaluation for forefoot surgery may be inaccurate if based solely on x-ray measurements.\n <\/jats:p>","DOI":"10.1177\/107110079201300902","type":"journal-article","created":{"date-parts":[[2013,3,3]],"date-time":"2013-03-03T03:31:12Z","timestamp":1362281472000},"page":"502-507","source":"Crossref","is-referenced-by-count":50,"title":["The Validity of Measurements Made on Standard Foot Orthoroentgenograms"],"prefix":"10.1177","volume":"13","author":[{"given":"Mark D.","family":"Perry","sequence":"first","affiliation":[{"name":"Orthopaedic Resident, The Johns Hopkins School of Medicine, Baltimore, Maryland."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Michael A.","family":"Mont","sequence":"additional","affiliation":[{"name":"Assistant Professor in Orthopaedic Surgery, The Johns Hopkins School of Medicine."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Thomas A.","family":"Einhorn","sequence":"additional","affiliation":[{"name":"Associate Professor of Orthopaedics and Director of Orthopaedic Research, The Mount Sinai School of Medicine, New York, New York."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"John D.","family":"Waller","sequence":"additional","affiliation":[{"name":"Chief of Foot and Ankle Surgery, Department of Orthopaedics, The Mount Sinai School of Medicine."}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[1992,11,1]]},"reference":[{"key":"bibr1-107110079201300902","doi-asserted-by":"publisher","DOI":"10.2106\/00004623-199072030-00003"},{"key":"bibr2-107110079201300902","first-page":"373","volume":"27","author":"Evans E.M.","year":"1945","journal-title":"J.
