To determine if there is a problem after being hit by a heavy object on the foot, you need to look at whether a closed injury or an open injury has been formed on the area that was hit. If the injury is open, further suturing will be required depending on the extent of the injury. If it is a closed injury, it means that the degree of injury is relatively minor. In addition, we should observe whether there is a local deformity of the injury, if there is a deformity and can feel the bone rubbing sound or femoral rubbing feeling, it means that the foot fracture after the heavy smash, indicating that the condition is more serious. If the injury is only a simple soft tissue injury, the smashed part is not very serious and can be recovered in a short time with the right treatment.
