Hypermobility of the TMT 1 joint is tested clinically in the sagittal plane, but an important deformation also exists in the transversal plane: metatarsus primus varus. This in vitro study was undertaken to investigate the relation between the mobility of the TMT 1 joint in these two planes and to investigate the correlation of the mobility with morphological variables. A second aim was to study the possible stabilizing effect of the tibialis anterior muscle, flexor hallucis longus muscle, and peroneus longus muscle on the TMT 1 joint.<\/jats:p>\n                  <jats:p>Nine embalmed human specimens were tested under standardized conditions. A 30-N force was applied to the head of the first metatarsal (MT 1) to pull in either the dorsal or medial direction. To simulate muscle force, 21 N was applied to the three tendons: all seven possible combinations of muscle action were tested in each plane of motion. Angular displacements were measured using 2-dimensional LED video registration.<\/jats:p>\n                  <jats:p>TMT 1 mobility is a relevant factor in MT 1 mobility in the sagittal and transversal planes, the peroneus longus has a stabilizing effect on this joint, and the effect of the flexor hallucis longus on this joint is different in both planes. When considering a Lapidus procedure for surgically correcting a hallux valgus, the mobility of MT 1 in the transversal plane should also be assessed, but so far no objective clinical test in this plane has been described.<\/jats:p>","DOI":"10.1177\/107110079902001007","type":"journal-article","created":{"date-parts":[[2013,3,3]],"date-time":"2013-03-03T03:31:12Z","timestamp":1362281472000},"page":"651-656","source":"Crossref","is-referenced-by-count":119,"title":["Mobility of the First Tarsometatarsal Joint in Relation to Hallux Valgus Deformity: Anatomical and Biomechanical Aspects"],"prefix":"10.1177","volume":"20","author":[{"given":"Frank W.M.","family":"Faber","sequence":"first","affiliation":[{"name":"Department of Orthopaedic Surgery, Leyenburg Hospital, The Hague, The Netherlands."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Gerrit-Jan","family":"Kleinrensink","sequence":"additional","affiliation":[{"name":"Department of Anatomy, Erasmus University, Rotterdam, The Netherlands."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Menno W.","family":"Verhoog","sequence":"additional","affiliation":[{"name":"Department of Anatomy, Erasmus University, Rotterdam, The Netherlands."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Annemieke H.","family":"Vijn","sequence":"additional","affiliation":[{"name":"Department of Anatomy, Erasmus University, Rotterdam, The Netherlands."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Christiaan J.","family":"Snijders","sequence":"additional","affiliation":[{"name":"Department of Biomedical Physics and Technology, Erasmus University, Rotterdam, The Netherlands."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Paul G.H.","family":"Mulder","sequence":"additional","affiliation":[{"name":"Department of Epidemiology and Biostatistics, Erasmus University, Rotterdam, The Netherlands."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jan A.N.","family":"Verhaar","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic Surgery, University Hospital Rotterdam Dijkzigt, Rotterdam, The Netherlands."}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[1999,10,1]]},"reference":[{"key":"bibr1-107110079902001007","doi-asserted-by":"publisher","DOI":"10.1177\/107110079701800810"},{"key":"bibr2-107110079902001007","doi-asserted-by":"publisher","DOI":"10.1302\/0301-620X.62B3.6997319"},{"key":"bibr3-107110079902001007","doi-asserted-by":"publisher","DOI":"10.1177\/107110079501600302"},{"key":"bibr4-107110079902001007","unstructured":"4.
