Fingertip injuries can occur in accidents at home, work, or play. An injury can involve a sharp cut, a crushing injury, a tearing injury, or a combination of these injury types. An amputation can result from slamming your finger in a car door or catching your ring on a hook or nail.
An injury or amputation can damage any part of the fingertip, including the:
Skin and soft tissue
Fingertip bone (distal phalanx)
Nail and underlying nailbed
The tips of longer fingers tend to be injured more often because they are last to escape from harm’s way.
Your fingertips are rich with nerves and are extremely sensitive. Without prompt and proper treatment, a fingertip injury can cause problems with hand function, and may even result in permanent deformity or disability. To ensure the best outcome, it is important to have your doctor examine your finger or thumb after an injury.
HAND & WRIST ANATOMY
If you have injured your finger, do the following as you are preparing to see your doctor:
Clean the injury, if possible, and cover it with a lightly compressive sterile dressing to minimize bleeding and protect the injured finger.
Elevate the injured hand to minimize swelling.
Immobilize the affected hand and wrist with a short splint.
If your fingertip is completely cut off, do the following:
Gently clean the amputated part with water or, if possible, with sterile saline solution.
Cover it in a moistened gauze wrap.
Place it in a watertight bag.
Place the bag on ice in a sealed container or another watertight bag.
Do not allow the amputated part to be in direct contact with ice, you could damage it further.
Bring the amputated part with you to the emergency room and maintain control over it until the doctor is able to evaluate you.
EXAMINATION & CARE
Your doctor will talk with you about your medical history and the circumstances of your injury. He or she will want to know if you have any medical conditions, such as diabetes, if you smoke, or if you take any medications. Your doctor will also want to know if you have experienced a previous injury to the affected hand.
To help plan your treatment, your doctor will ask several questions. These may include:
How and when did your injury occur?
Is the injured finger on your dominant hand?
What do you do for a living?
What are your recreational activities?
Do you smoke or use tobacco products?
Have you ever had hand problems caused by osteoarthritis, diabetes, rheumatoid arthritis, or any other medical condition?
Is your tetanus immunization up-to-date?
Physical Examination and Immediate Care
Your doctor may give you a numbing injection (digital block anesthesia) to help reduce the pain in your injured finger. He or she will irrigate, or wash out, your wound with a saline solution to see it more clearly and to reduce the risk of infection.
Your doctor will examine your finger carefully, looking for:
Injury to the nail and nailbed
Your doctor will then thoroughly clean out the wound, removing dead tissue and contaminants. This procedure is called “debridement.” This will reduce your risk for infection.
If your doctor suspects that you have broken bones, he or she may order x-rays. Some fingertip injuries can cause bleeding under the fingernail—a condition called “subungual hematoma.” If this is the case with your injury, your doctor may pierce your fingernail to relieve the pressure. He or she may also remove your fingernail if the nailbed underneath requires repair.
Your doctor may prescribe an antibiotic and/or give you a tetanus shot to prevent infection.
The goal of treatment is to have a pain-free fingertip that is covered by healthy skin and functions normally. Your doctor will try to preserve the length and appearance of your finger.
Treatment for a fingertip injury or amputation depends on the angle of the cut and the extent of the injury. To determine the best treatment for your injury, your doctor will consider your general health and lifestyle, as well as your preferences.
Injury Without Exposed Bone
Minor tissue injury. If your fingertip wound is small and not deep enough to expose bone, it may heal on its own. Your doctor may place a protective dressing over the wound with instructions to change the bandage regularly. He or she may recommend that you wear a splint to protect the area while it heals.
After about 24 to 48 hours, your doctor may recommend that you soak your finger daily in a solution of warm, soapy water or saline solution with peroxide or betadine. After 48 hours, range-of-motion finger exercises may be started to avoid stiffness.
Complete healing usually takes from 2 to 4 weeks, although stiffness and hypersensitivity may remain longer, depending on the severity of the injury.
Larger tissue injury. If your fingertip wound is large and open, there may not be enough remaining skin to heal and cover the open area.
In some cases, the wound may be left open to heal gradually on its own. This is called healing by secondary intention.
Sometimes, surgery may be required to ensure healing. Surgical procedures used to treat larger tissue injuries may include:
Skin grafting. In this procedure, a piece of skin (skin graft) is taken from the outside of your hand, your forearm, or another site and used to cover the injury. Both the wound and the donor site are closed with stitches during the procedure.
Reconstructive flap surgery. Because a skin graft does not have its own blood supply, it may not be sufficient for some larger tissue injuries. If this is the case, your doctor may take a full-thickness flap of skin from a healthy part of your injured hand and use it to cover your wound. This procedure is discussed in greater detail in the section below.
Exposed Bone Injury
For injuries that expose the bone, there may not be enough tissue around the wound to stitch the wound closed. Sometimes, the bone needs to be shortened so that your wound can be stitched closed. Shortening the bone slightly usually does not hurt your ability to use your hand.
Reconstructive flap surgery. It may be necessary to cover the wound with new skin, as well as the fat and blood vessels underneath the skin. This is called “reconstructive flap surgery.”
The flap of skin and soft tissue is taken from a healthy part of the same hand. Common donor areas are the injured finger itself, a non-injured finger, and the palm of the hand. A skin graft may be used to cover the donor area and to help it heal.
In some cases, the flap is not fully removed from the donor area. The flap is sewn over the wound but it remains connected to the donor area. This is done to ensure a healthy blood supply to the flap as it heals over the wound.
Fingertip Amputations in Young Children
Doctors treat fingertip amputations somewhat differently in children younger than 6 years of age. After thoroughly cleaning and preparing an amputated fingertip, the surgeon may reattach it to the finger. The fingertip may continue to grow relatively normally, even if bone was exposed. This is especially possible in children younger than 2 years of age.
Your doctor will consider many things when determining whether to reattach your child’s amputated fingertip, including:
Your child’s age and general health.
The condition of the amputated part.
How the injury occurred.
