The lateral fibulotalocalcaneal ligament (LFTCL) complex consists of the inferior fascicle of the anterior talofibular ligament (ATFL) which is connected by arciform fibres with the calcaneofibular ligament (CFL). The superior fascicle of ATFL is an independent structure that should be assessed individually. MRI evaluation of these distinct fascicles and the arciform fibres has not been described. The aim of this study is to identify the anatomical relationship of these components of the LFTCL complex in healthy individuals on MRI.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>Thirty ankles from healthy volunteers were imaged using 3D volumetric MRI. The ATFL fascicles and size were evaluated. Presence of arciform fibres connecting the inferior ATFL fascicle and CFL to form the LFTCL complex and anatomical relationship around the lateral ligament complex were assessed.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Both the superior and inferior ATFL fascicles were observed in 26 (86.7%) ankles. The superior ATFL fascicle was significantly larger in all specimens (39% longer and 80.7% wider). For the specimens with a single fascicle, this was similar in size to the superior fascicle observed in the other 26 specimens. These measurements were not affected by age or gender. Arciform fibres of the LFTCL complex were identified in 22 (84.6%) specimens with two ATFL fascicles and three (75%) ankles with a single ATFL fascicle. Connecting fibres from the ATFL to PTFL were observed in 19 (63.3%) ankles while connections between the CFL and PTFL were identified in 21 (70%) ankles. Five ankles had a perforating artery visualized in the intervening space between the superior and inferior ATFL fascicles (a branch of the lateral tarsal artery of the dorsalis pedis artery).<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>Two distinct ATFL fascicles may be identified in the majority of ankles on MRI. Isolated injury to the superior fascicle identified on MRI may be useful when diagnosing patients presenting with symptoms of subtle instability without overt ankle laxity on clinical examination. The current study is the first to identify the arciform fibres of the LFTCL complex supporting isolated ATFL repair in the presence of intact LFTCL complex.<\/jats:p><\/jats:sec><jats:sec><jats:title>Level of evidence<\/jats:title><jats:p>Level III.<\/jats:p><\/jats:sec>","DOI":"10.1007\/s00167-022-07275-x","type":"journal-article","created":{"date-parts":[[2022,12,20]],"date-time":"2022-12-20T13:02:41Z","timestamp":1671541361000},"page":"2192-2198","update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":27,"title":["Individual fascicles of the ankle lateral ligaments and the lateral fibulotalocalcaneal ligament complex can be identified on 3D volumetric MRI"],"prefix":"10.1002","volume":"31","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-0309-8096","authenticated-orcid":false,"given":"Choon Chiet","family":"Hong","sequence":"first","affiliation":[{"name":"<!--<label>1<\/label>--> Fortius Clinic (FIFA Medical Centre of Excellence) 17 Fitzhardinge Street W1H 6EQ London UK"},{"name":"<!--<label>2<\/label>--> Department of Orthopaedic Surgery National University Hospital 1E, Kent Ridge Road 119228 Singapore Singapore"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Justin C.","family":"Lee","sequence":"additional","affiliation":[{"name":"<!--<label>1<\/label>--> Fortius Clinic (FIFA Medical Centre of Excellence) 17 Fitzhardinge Street W1H 6EQ London UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Anika","family":"Tsuchida","sequence":"additional","affiliation":[{"name":"<!--<label>1<\/label>--> Fortius Clinic (FIFA Medical Centre of Excellence) 17 Fitzhardinge Street W1H 6EQ London UK"},{"name":"<!--<label>3<\/label>--> Department of Orthopaedic Surgery Noordwest Clinics Alkmaar Wilhelminalaan 12 1815 JD Alkmaar The Netherlands"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mai","family":"Katakura","sequence":"additional","affiliation":[{"name":"<!--<label>1<\/label>--> Fortius Clinic (FIFA Medical Centre of Excellence) 17 Fitzhardinge Street W1H 6EQ London UK"},{"name":"<!--<label>4<\/label>--> Department of Joint Surgery and Sports Medicine Tokyo Medical and Dental University Tokyo Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mary","family":"Jones","sequence":"additional","affiliation":[{"name":"<!--<label>1<\/label>--> Fortius Clinic (FIFA Medical Centre of Excellence) 17 Fitzhardinge Street W1H 6EQ London UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Adam W.","family":"Mitchell","sequence":"additional","affiliation":[{"name":"<!--<label>1<\/label>--> Fortius Clinic (FIFA Medical Centre of Excellence) 17 Fitzhardinge Street W1H 6EQ London UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6043-698X","authenticated-orcid":false,"given":"Miki","family":"Dalmau\u2010Pastor","sequence":"additional","affiliation":[{"name":"<!--<label>5<\/label>--> Human Anatomy Unit, Department of Pathology and Experimental Therapeutics, School of Medicine and Health Sciences University of Barcelona Barcelona Spain"},{"name":"<!--<label>6<\/label>--> MIFAS By GRECMIP (Minimally Invasive Foot and Ankle Society) Merignac France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"James","family":"Calder","sequence":"additional","affiliation":[{"name":"<!--<label>1<\/label>--> Fortius Clinic (FIFA Medical Centre of Excellence) 17 Fitzhardinge Street W1H 6EQ London UK"},{"name":"<!--<label>7<\/label>--> Department of Bioengineering Imperial College London SW7 2AZ London UK"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2022,12,20]]},"reference":[{"key":"e_1_2_10_2_2","first-page":"483","article-title":"Sprained ankles.
