Deformity of the hallux is often accompanied by an enlarged first intermetatarsal (IM 1-2) angle. It has been hypothesized that subjects having an abnormally large IM 1-2 angle have laxity of the first ray. Objectives of this study were to compare dorsal mobility of the first ray in subjects with hallux valgus to asymptomatic controls, and to investigate the relationship between dorsal mobility and the IM 1-2 angle. Fourteen subjects (age 23\u201381) with hallux valgus were matched by gender and age to control subjects. The IM 1-2 angle was measured from radiographs. A load-cell device measured dorsal mobility of the first ray under a standard load of 55 N. Pearson's correlation coefficient identified a marginal correlation (r = .51) between IM 1-2 angle and dorsal mobility. An independent t-test showed a statistically (P &lt; 0.01) larger amount of dorsal mobility in the group of subjects having an hallux valgus. Mobility of the first ray was increased in subjects with hallux valgus and a large IM 1-2 angle may be an indicator of increased dorsal mobility.<\/jats:p>","DOI":"10.1177\/107110070102200203","type":"journal-article","created":{"date-parts":[[2017,2,14]],"date-time":"2017-02-14T03:48:58Z","timestamp":1487044138000},"page":"98-101","source":"Crossref","is-referenced-by-count":96,"title":["First Ray Dorsal Monility in Relation to Hallux Vlagus Deformity and First Intermetatarsal Angle"],"prefix":"10.1177","volume":"22","author":[{"given":"Ward Mylo","family":"Glasoe","sequence":"first","affiliation":[{"name":"Staff Physical Therapist, Research Therapist, Physiotherapy Associates, Cedar Rapids, Iowa 52401"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mary K.","family":"Allen","sequence":"additional","affiliation":[{"name":"Staff Physical Therapist, Research Therapist, Physiotherapy Associates, Cedar Rapids, Iowa 52401"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Charles L.","family":"Saltzman","sequence":"additional","affiliation":[{"name":"Associate Professor, Departments of Orthopaedic Surgery and Biomedical Engineering, University of Iowa Hospitals and Clinics, Iowa City, Iowa 52242"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2001,2,1]]},"reference":[{"key":"bibr1-107110070102200203","doi-asserted-by":"publisher","DOI":"10.1177\/107110079501600506"},{"key":"bibr2-107110070102200203","doi-asserted-by":"publisher","DOI":"10.1177\/107110079701800802"},{"key":"bibr3-107110070102200203","doi-asserted-by":"publisher","DOI":"10.1007\/BF00197458"},{"key":"bibr4-107110070102200203","doi-asserted-by":"publisher","DOI":"10.1007\/BF00206143"},{"key":"bibr5-107110070102200203","doi-asserted-by":"publisher","DOI":"10.1177\/107110079902001007"},{"key":"bibr6-107110070102200203","doi-asserted-by":"publisher","DOI":"10.1177\/107110079501600302"},{"key":"bibr7-107110070102200203","doi-asserted-by":"crossref","unstructured":"7.
