Ecchymosis on the Plantar Side of the Foot

Abstract

Although the incidence of Lisfranc injuries is not high, they are related to long-term disability of the foot such as malalignment, functional deficits and weight bearing difficulties. Delayed treatment or missed diagnosis of Lisfranc injuries can result in significant complications. Lisfranc injuries result from both indirect and direct trauma. A 43 years old man came into the emergency with pain in his right foot after a direct trauma to the anterior part of his foot while playing soccer.Introduction Lisfranc injuries are relatively uncommon, representing approximately 0.2% of all fractures. Although the incidence of Lisfranc injuries is not high, they are related to long-term disability of the foot such as malalignment, functional deficits and weight bearing difficulties [1]. Delayed treatment or missed diagnosis of Lisfranc injuries can result in significant complications. Case ReportA 43 years old man came into the emergency with pain in his right foot after a direct trauma to the anterior part of his foot while playing soccer. He had pain over the dorsal side of the midfoot when palpated and an ecchymosis on the plantar arch of right foot (Figure 1). There was no remarkable abnormality in the remaining physical examination. The plain radiograph is not remarkable but a possible fracture at the basis of first metatarsal bone (Figure 2). Computerized tomography revealed a separated fracture of the first metatarsal bone including tarsometatarsal joint (Figure 3). J o u r n a l of Ar th r i t is
