Surgery is required for the majority of tarsometatarsal injuries. The treatment of tarsometatarsal injuries is usually done by reduction of the fracture or dislocation by means of screws that are inserted internally into the bones across the joints. The screws are typically left in for approximately four to five months following the surgery. Often after this time they are removed.
There is no cast after the surgery. No walking on the foot is permitted for about six weeks and then walking is initiated with a removable boot. Swimming and biking are permitted early on. Walking in the boot is gradually discontinued at about ten weeks.
If untreated, a fracture or dislocation of the tarsometatarsal joint will often lead to painful arthritis that requires treatment. Arthritis is common if the joints are not carefully lined up and held with screws. If arthritis does occur, then these joints need to be fused.
