Name of journal: Journal of computer assisted tomographyAbstract: CONCLUSIONS: Our exploratory cross-sectional analysis shows that SAD measurement changes during motion using 4DCT are correlated with the tibiotalar OA grading. This measurement may be used but requires confirmation in larger studies including patients with actual syndesmotic injuries. Copyright © 2022 Wolters Kluwer Health, Inc. All rights reserved.METHODS: Sixteen ankle joints underwent 4DCT imaging during active dorsiflexion-plantarflexion. Syndesmotic anterior distance (SAD) and syndesmotic translation (ST) were obtained by a foot-and-ankle surgeon. We used Kellgren-Lawrence (KL) grading to determine tibiotalar OA.OBJECTIVE: The aim of this study was to evaluate the association between 4-dimensional computed tomography (4DCT)-derived measurements of tibiofibular syndesmosis during active dorsiflexion-plantarflexion motion and the presence of tibiotalar osteoarthritis (OA).RESULTS: Of 16 scanned ankles, 12 ankles had KL >=2 at the tibiotalar joint. In these ankles, SAD (-0.4, P = 0.02) and ST (-0.9, P = 0.006) measurements significantly changed during the dorsiflexion-plantarflexion motion. Changes in SAD measurements were significantly correlated with the KL grades (correlation coefficient: -0.688, P = 0.003); however, the changes in ST measurements were not significantly correlated with the KL grade.All authors: Dalili D, de Cesar Netto C, Demehri S, Hafezi-Nejad N, Haj-Mirzaian A, Mousavian A, Schon LC, Shakoor DFiscal year: FY2022Digital Object Identifier: Date added to catalog: 2022-07-06
