Recovery from leg crush injuries is generally slow, and the exact recovery time varies depending on the injury. If the limb is destroyed after crushing and there are no other injuries, it can recover in half a month or so after amputation. However, patients with life-saving and limb-saving injuries often have a longer recovery time. If the whole leg is crushed, it is necessary to rescue the shock first, then to control the damage site for surgery, followed by skin implantation, and finally to recover gradually until discharge, and the whole course of treatment takes 2-3 months. Therefore, crush injuries are more serious and generally cannot be healed in a short time.
