ABSTRACT
BACKGROUND:As a novel noninvasive method, high frequency ultrasound has been used for the detection of skeletal muscle widely. OBJECTIVE:To detect the thickness of the dorsalLisfrancligament between the first (medial) cuneiform (C1) and second metatarsal (M2) using high frequency ultrasound to evaluate the feasibility and clinical application value of high frequency ultrasound for the detection of theLisfrancjoint. METHODS:Both feet of 100 healthy volunteers were included and the thickness of dorsalLisfranc ligament and the distance between C1 and M2wereexamined using high frequency ultrasound. RESULTS AND CONCLUSION:The display rate of high frequency ultrasound for the dorsalLisfranc ligament in the 100 healthy volunteers was 100%. There was no significant difference in the thickness of the dorsalLisfrancligament between both feet or sexes in adults(P> 0.05); as did the distance between C1 and M2 (P> 0.05). These findings suggest that visual dorsalLisfrancligament is detected by high frequency ultrasound. The measurement of the distance between C1 and M2by high frequency ultrasound may be a feasible, noninvasive, low-cost, and early diagnostic method forLisfrancinjuries.
