The sequelae of a comminuted metatarsal fracture include the following: First, there may be non-healing because with a comminuted fracture, it causes severe damage to the blood supply. Adequate blood supply is necessary for the fracture to heal, and a comminuted fracture, which often results in a poor or poor blood supply, will result in a non-healing fracture at this time. Secondly, there may be delayed healing, this healing is also called delayed healing when it does not heal at the time when it should heal in three months, but a comminuted fracture causes a reduced blood supply, but it does not have no blood supply at all, it can still be long, but long may take longer. Third, fracture disease may occur, that is, after the fracture heals, there may be localized swelling, pain, or discomfort, which may take six months to a year to disappear, which is called fracture disease. Fourth, there may be bone discontinuity or osteomyelitis. Because of the metatarsal comminuted fracture, there may be soft tissue defects or open fractures, and this time the healing time is longer, and there may even be infection, osteomyelitis and so on.
