Abstract
When examining patients with injuries of the tarsometatarsal joint, the physician must pay attention to the foot as a whole.An extremely rare foot injury has been described in which axial and compressive forces cause simultaneous dislocation of the tarsometatarsal joint and the metatarsophalangeal joint of the same or adjacent ray. The following is a report of one of these rare injuries.We will also discuss probable mechanism and diagnosis of this rare traumatic injury.

One of the mechanisms of Lisfranc joint injuries is axial loading associated with compression forces [2]
Summary
Lisfranc joint injuries should be considered in every patient involved in a motor vehicle accident and retrospective studies have shown that these injuries are missed in up to 20% of cases on initial evaluation [1]. Dislocations of the lesser metatarsophalangeal joints are produced by axial forces usually during hyperextension of the toes [2] This type of trauma is not common and reduction of the dislocation of these joints is achieved with traction, dorsiflexion, and plantarflexion, but it has been reported that closed reduction is successful in 50% of cases [2]. English used the term "linked toe metatars" to describe the condition and proposed the theory that traction on the soft tissue, especially the first dorsal interosseous muscle after dislocation of the tarsometatarsal joint, causes the metatarsophalangeal joint to dislocate. He based his theory on the obser-. All of these emphasize the fact that the examining physician must pay adequate attention when examining patients with either of these injuries
