The dangers of fourth metatarsal fracture include dorsalis pedis fascia intercompartmental syndrome, pain in walking caused by non-union of the fracture or deformity healing, and limitation of movement.
A broken blood vessel and bleeding from the broken end of the fracture after a fourth metatarsal fracture can cause swelling of the dorsum of the foot, and if the swelling is severe, dorsalis pedis fascia intercompartmental syndrome may develop, which is a more serious complication that requires an incision and decompression as soon as possible.
The fourth metatarsal is involved in the formation of the plantar arch. A fracture changes the structure of the arch forces. If the fracture does not heal over time or heals abnormally, it can result in a change in the arch forces, which can lead to pain when walking and an inability to walk for long periods of time.
If the fourth metatarsal fracture is not significantly displaced, it can be immobilized with a plaster cast; if it is significantly displaced, surgery is recommended to restore the original anatomical structure of the fourth metatarsal to prevent after-effects.
If a fracture of the fourth metatarsal occurs inadvertently, it is recommended that the patient go to the hospital for a complete examination and targeted treatment.
