A Case Report of Floating Metatarsal: Concomitant Dislocation of the Tarsometatarsal and Metatarsophlangeal Joints of the Second Toe

An extremely rare case of floating second metatarsal is reported. The reported case is a young man with simultaneous dislocation of tarsometatarsal and metatarsophalangeal joints of the second metatars following a car accident. Because of patient's discontent for open surgery, blind percutaneus pinning was performed that was not completely successful and in follow up radiography, 18 months later, degenerative joint disease (DJD) signs were observed. In examining patients with injuries of the tarsometatarsal joint, the physician must pay attention to the whole foot as the forces acting on it which are axial and compressive can injure the metatarsophalangeal joint (in the same or the adjacent ray) as well. After reporting the case, we will discuss the probable mechanism and different aspects of this rare traumatic injury.
