High-frequency ultrasonic screening method and characters of plantar metatarsal levelin normal adults / 中国医学影像技术

ABSTRACT

Objective To investigate high-frequency ultrasonic characters and screening method of plantar metatarsal level in normal adults.Methods Plantar metatarsal level were examined with high frequency ultrasound in 40 normal adults.The base,body and head of the first to the fifth metatarsal were used as anatomical location markers.The ultrasonic characters and screening method were described and recorded.Results The plantar skin,plantar fat pad,plantar aponeurosis and deep muscular structures,including the flexor digitorum brevis,abductor hallucis,abductor digiti minimi,lumbricalis,felxor hallucis brevis,flexor digiti minimi brevis,abductor hallucis and plantar interossei were illuminated in detail with high-frequency ultrasound.Conclusion High frequency ultrasound can be used to depict anatomical structures of plantar metatarsal level.
