  The term “Floating metatarsal” is defined as a complex injury which includes simultaneous dislocation of both metatarsal joints. This injury is very rare and if is remained undiagnosed then the final result is disorganization of the foot and leads to chronic pain and incapacity. We present a 52 years old female who admitted to emergency department after a fall from a height and appeared with Lisfranc injury Myerson type A of right foot, simultaneous distal dislocation of 2nd - 3rd metatarsophalangeal joints, subcapital fracture of 4th metatarsal and a fracture of the base of proximal phalange of little toe. We performed open reduction and internal fixation of both injuries (primary partial arthrodesis for Lisfranc injuries and Kirschner wire for dislocation of 2nd - 3rd metatarsophalangeal joint). At six months final follow-up the patient was very satisfied and the AOFAS score was 93. The aim of this study has two objectives: first, to describe this rare injury with scope to get the physician at the emergency department suspect that the tarsometatarsal joint could be accompanied with other injuries of the metatarsophalangeal joints and second, to analyze the mechanism of injury and the modalities of treatment.
