A mutilating hand injury is severe damage to the hand. The injury may include damage to bones, tendons, soft tissues, nerves, and skin. It can become a life-threatening condition.

If you have this type of injury, call for medical help right away. Immediate care may result in a better repair and decrease the chance of further damage. Untreated, this can lead to a serious infection.

Mutilating hand injuries can be caused by a variety of factors, including:

  • Industrial accidents
    • Machine injuries
    • Power tool injuries
  • Crushing accidents
  • Burns
  • Chemical exposure
  • Car accidents
  • Farming injuries

Risk Factors

Factors that may increase your risk of injury include:

  • Having an occupation that requires use of dangerous machinery
  • Removing safety guards from machinery, such as power saws or wood chippers
  • Using short-cuts and improper technique while using machinery
  • Using your hands to remove clogged grass from lawn mowers or snow from snow blowers without shutting off the power
  • Operating machinery or vehicles under the influence of alcohol or medications that cause impairment during use

Diagnosis

When you are brought to the emergency room, a doctor will quickly assess your injury. Your wound will be inspected and your hand’s nerves and tendons will be tested. You will be asked to explain how the injury happened. You will also be asked which of your hands is dominant.

Imaging tests assess damage to the bones, nerves, tendons, skin, or other soft tissues. These may include:

You may need examination under anesthesia to:

  • Allow the doctor to closely examine your wound
  • Remove debris or dirt

Treatment

Immediate treatment is focused on stopping any bleeding. The doctor will make sure your vital signs are stable. An IV will be started to give you fluids and medications. You may be referred to a hand specialist for surgery. Depending on your injury, you may receive the following treatment:

Tetanus Shot

This will protect you from a tetanus infection.

Medications

The following types of medication may be given:

  • Pain medications
  • Anesthesia to examine the wound closely
  • Antibiotics to prevent a wound infection

Wound Irrigation

Sterile saline is used to clean the wound. This will help prevent infection and further injury.

Hand Surgery

You may need to have immediate surgery. If your injury is less severe, your hand will be dressed and splinted. You will have a follow-up visit with a hand surgeon.

The type of surgery necessary depends upon the injury. Examples include fusing damaged joints and reattaching fingers. Often, several surgeries are necessary for this type of injury.

Rehabilitation

You will likely need physical therapy to regain strength and movement in your hand. You may also work with an occupational therapist to learn how to function with your injured hand.

Prevention

To help reduce your chance of injuring your hands, take the following steps:

  • Do not operate machinery that you are unfamiliar with.
  • Follow all safety instructions when operating tools or machinery. Be especially careful when using snow blowers and lawn mowers. These commonly used tools result in many hand injuries each year.
  • Do not put fingers or hands near moving parts of machinery.
