Fractures of the dorsum of the foot will heal on their own without a cast, but may lead to healing deformities and other conditions that may affect future function. Fractures of the dorsum of the foot can heal on their own, generally after four periods of hematoma formation, fibrous bone scab formation, bony bone scab formation, and bone scab remodeling can be basically restored to the normal bone structure, and the cast plays a role in restricting the activities and immobilization. If the fracture is not immobilized by plaster during the recovery period, the affected area may be dislocated due to impact, activities, etc. Although the reconstruction of the bone scab can correct the displacement, its reconstruction has its certain limit, and it will be difficult to completely correct the deformity if the deformity is serious, which will lead to dysfunction of the foot after the healing process. Patients with dorsal foot fracture should be immobilized in a plaster cast to avoid a decrease in the quality of life in the future.
