The length of time it will take for a crush injury to heal will depend
on the extent of damage. A hand that’s partially crushed with no
bone fractures, for example, may heal in a few days or weeks. A severely
crushed limb may take multiple surgeries and months to heal. Some crush
injuries are so severe that they require surgical amputation. You should
talk to your doctor and see specialists as needed to ensure you have the
best opportunity to heal.
