Abstract:
Objective To explore the MRI characteristics of anatomy and injuries of the tendons and ligaments in the midfoot.Methods Twenty healthy volunteers and 46 patients with midfoot trauma were selected for retrospective analysis.All subjects underwent examination on MR T1WI and proton density-fat suppression(PD FS)scans on three planes,respectively.Then the MRI features of tendon and ligaments injury were compared.Results The tendons and ligaments of 20 healthy volunteers(40 lateral feet)showed homogeneous low signal intensity with varing thickness.The anterior tibialis tendons showed a thin linear shape,and the posterior tibialis tendons showed a slightly thick band with uniform low signal intensity,and the calcaneonavicular ligament showed thin linelike low signal in different directions.In the 46 patients with midfoot injuries,there were 16 cases of anterior tibialis tendons injuries,18 cases of posterior tibialis tendons injuries,and 12 cases of calcaneonavicular ligament injuries.According to the MRI findings,the degree of injuries of tendons and ligaments was divided into injury,partial tear,and complete rupture.Conclusion MRI can clearly show the anatomy and injury features of ligaments and tendons in midfoot,which is of important value for the early diagnosis and accurate treatment of the ligaments and tendons injuries.
