- High-energy Tarsometatarsal Joint Injury: More severe TMT joint injuries occur as a result of motor vehicle accidents or from direct trauma, such as a fall from a height. High-energy injuries are more serious and can result in multiple fractures and dislocations of the tarsometatarsal joints.
- Crush Injuries to the Tarsometatarsal Joint: Direct crush injury to the foot can result in tarsometatarsal joint injury such as a heavy weight being dropped on the foot or a car driving over top of a foot.
