What Is Boxer's Fracture?
A boxer's fracture is a break through the bones of the hand that form the knuckles. Some doctors use the term "brawler's fracture" rather than "boxer's fracture" because a boxer is not likely to get this injury. The less well-trained brawlers have to learn how to punch without hurting themselves.
The metacarpal bones in the hand connect the bones in the finger to the bones in the wrist. There are five metacarpal bones, one to connect each finger to the wrist. All of the metacarpal bones have the same anatomic structure. Each consists of the base, the shaft, the neck, and the head.
- The base of the metacarpal bone is the portion that attaches to the bones of the wrist.
- The shaft is the long, slender portion of the bone.
- The neck is the portion of the bone that connects the shaft to the head. The head of the metacarpal bone connects the metacarpal bone to the bone of the finger.
- The head of the metacarpal bones forms the knuckle of an enclosed fist.
- A boxer's fracture involves a break in the neck of the metacarpal. This was described originally in the fracture of the metacarpal bone of the little (small) finger because this is the most common one to break when punching an immovable object.
Boxer's fractures occur in the metacarpal bones that connect the ring finger or the little finger to the wrist. These are known as the fourth and fifth metacarpal bones. Some doctors include breaks in the neck of the second and third metacarpal bones in the definition of a boxer's fracture. The second metacarpal bone connects the index finger to the wrist, and the third metacarpal connects the middle finger to the wrist.
What Are the Signs and Symptoms of Boxer's Fracture?
The typical symptoms of a boxer's fracture are pain or tenderness centered in a specific location on the hand corresponding to one of the metacarpal bones, around the knuckle. The person may also note pain with movement of the hand or fingers.
- When a bone is broken, a snapping or popping sensation in the affected bone may be experienced.
- The hand may swell, discolor, or bruising around the injury site. Deformity of the broken bone or the knuckle also may be noted. There may also be an abnormal movement of the broken bone fragments. The doctor may be able to produce pain by pressing on the broken bone. In addition, pain can be produced by grabbing the finger that attaches to the metacarpal bone that was hurt and pushing it inward toward the broken bone.
- If a fist is made with the affected hand, the doctor may notice misalignment of the associated finger. The doctor may see a deformity of the broken bone. When making a fist, the finger involved may bend toward the thumb more than is usual. This is known as rotation, and, though not always seen, its presence may indicate the possibility of a more serious type of boxer's fracture.
- Another common sign of a possible boxer's fracture is a cut on the hand. A cut in the skin associated with a boxer's fracture may indicate a more serious type of boxer's fracture.
When Should You See a Doctor for Boxer's Fracture?
Any time a person has an injury and a fracture are suspected, contact a doctor for instructions. If a doctor is unavailable, go to the emergency department for evaluation. Contact a doctor or go to the emergency department if the affected individual's hand or arm has been splinted or cast and they develop increasing pain, numbness, or tingling in the fingers on the cast or splinted arm. Any signs of infection from a cut or sutured wound also require evaluation by a doctor.
Any hand injury that has signs or symptoms suggesting a fracture should be evaluated by a doctor. This may be accomplished by contacting a doctor. If the affected individual cannot see a doctor immediately, go to a hospital's emergency department.
How Is a Boxer's Fracture Diagnosed?
Physical examination in conjunction with X-rays is essential to properly diagnose a boxer's fracture. Findings that suggest the need for X-rays include activities that increase the risk of fracture, deformity of the hand, localized tenderness, swelling of the hand, discoloration, decreased ability to move the hand, wrist or fingers, numbness, unequal temperatures between the injured and uninjured hands, or a cut caused by teeth when punching someone in the mouth (resulting in a human bite injury).
The doctor will determine if X-rays are warranted based on the circumstances surrounding the injury. After the doctor obtains detailed information about how the hand was injured, a physical examination is the next step in the evaluation.
- Swelling and discoloration commonly are seen with fractures and are associated with damage caused by direct trauma to the bone and surrounding muscles, ligaments, tendons, nerves, and blood vessels.
- Decreased ability to move the hand in the usual directions and manner may result from the swelling or pain associated with the fracture. The doctor will ask the patient to make a fist. This helps to determine the extent of the injury, as well as the type of treatment that may be needed. This also may indicate if a ligament has been torn. Torn ligaments will not show up on standard X-rays, but they sometimes occur with fractures.
X-rays of the hand are performed to look at the hand from three different directions. Evaluating the hand from different viewpoints reduces the risk of not seeing a fracture on the X-ray. After evaluating the bones on the X-ray, the doctor can determine what type of fracture is present. In certain cases, the doctor may order more X-rays, with special views to look for hard-to-find fractures. These studies are ordered when the standard X-rays do not show a fracture and the information regarding the patient's injury or physical examination suggests the presence of a hard-to-find fracture.
On physical examination the doctor will look for the presence of foreign bodies in the hand. Activities that could cause a foreign body to become lodged in the hand include:
punching another person in the mouth
- an animal bite
- being cut with a sharp object
- a penetrating injury
- abrasions or splinters from an object
Foreign bodies that may show up on X-rays are glass, bone, metal, and stones. However, organic or living materials such as wood or plants will not show up on standard X-rays and will require further studies if their presence is suspected.
What Natural Home Remedies Treat Boxer's Fracture?
Home care for boxer's fractures can be divided into care prior to seeing a doctor, and care after a diagnosis of a boxer's fracture is made.
The immediate goals of caring for an injured hand are to minimize pain and swelling, minimize the risk of infection of any open cuts, and to prevent further injury caused by an unstable fracture.
- The best approach to reduce pain and swelling is to apply an ice pack to the injured area. If ice is not available, placing a towel soaked in cold water on the injured hand will work. Elevating the injured hand will also help reduce swelling.
- An open cut sustained at the time of injury suggests an open fracture - a type of broken bone that is at increased risk for infection and poor healing. All cuts should be washed with soap and water and then covered with a clean bandage immediately to reduce the risk of infection.
- A key technique to prevent further injury from a fracture is to immobilize the injured hand. This is often best accomplished by holding the injured hand in the uninjured hand. In addition, take care not to use the injured hand to lift objects or perform any task that would place stress on it. Using a broken hand that is not properly immobilized can cause damage to the surrounding muscles, blood vessels, tendons, ligaments, and nerves.
Home care after the diagnosis of boxer's fracture is based on how the doctor treated the hand. Home care includes pain management, cast or splint care, and monitoring for signs of infection.
- Bones, like many other parts of the body, contain nerve fibers that transmit the sensation of pain. Pain from broken bones is caused by swelling due to the injury of the tissues around the fracture site, or by the broken bone moving against the nerve fibers. Pain should lessen once a broken bone is immobilized and movement is prevented. Some degree of pain may still persist. When a doctor writes a prescription for pain medication, it is important to take the medication as prescribed. This will help alleviate pain and will minimize the risk of any unwanted side effects from the medication. For mild pain, over-the-counter acetaminophen (Tylenol) or ibuprofen (Advil) may be used as directed on the label. This should be discussed with the doctor before taking these medicines.
- Splinting or casting commonly is performed on all boxer's fractures that do not require immediate surgery. All splints and casts should be kept dry in order to maintain their strength. A complication that can be seen with this procedure is the cast becoming too tight from the swelling of the fracture. When this happens, the patient may feel pain under the cast or splint. Another sign is numbness or tingling in the fingers on the casted hand. In addition, the finger may become cool to the touch. When this occurs, call the doctor or go to a hospital's emergency department immediately for evaluation.
- Infection can occur at an open cut. Wounds should be kept clean and covered until healing is complete. If stitches are used to close a cut, the doctor will provide additional instructions on how to care for the stitches and when they should be removed. It is important to follow these directions carefully to minimize the risk of infection. Monitor any cuts for signs of infection. Warning signs of infection include redness, red streaking away from the cut, warmth, or swelling around the site of the cut. Pus may also drain from the wound. Any of these signs requires immediate medical evaluation.
What Is the Treatment for Boxer's Fracture?
If a boxer's fracture is detected, the primary goals of treatment are to immobilize the hand to permit proper healing and to alleviate the pain associated with fractures.
In order to properly immobilize most broken bones, the splint should immobilize the joints above and below the site of injury. In the case of a boxer's fracture, different types of splints may be used. One type of splint may extend from the fingers, with the fingertips exposed, to the forearm near the elbow. Another type of splint that has been shown to be effective for some boxer's fractures of the little finger is to buddy-tape the ring finger and little finger together. The doctor will decide what type of splint will treat the patient's fracture the best.
- When a boxer's fracture occurs, it is possible for a portion of the metacarpal bone to move out of normal alignment. This is called angulation. The amount of angulation will determine what type of treatment is required to ensure proper healing. People with boxer's fractures who have acceptable amounts of angulation may be splinted in the emergency department or doctor's office.
- Any degree of angulation in the second or third metacarpal bones is considered abnormal and requires referral to a hand specialist for possible surgical repair. Boxer's fractures of the fourth and fifth metacarpal bones only require surgery if large degrees of angulation is present and the bones cannot be moved into the correct place by pulling and pushing on them.
- Because broken bones can cause significant amounts of pain, pain management is an important aspect of treating broken bones. Pain management is best accomplished with anti-inflammatory medicines and pain relievers. Acetaminophen (Tylenol) or ibuprofen (Advil) usually provides good pain relief with few side effects. These over-the-counter medications, or any prescription pain medicines, should be taken as directed to decrease the risk of side effects.
Do You Need to Follow-Up with Your Doctor After Boxer's Fracture Treatment?
A person with a boxer's fracture frequently is advised to follow-up with a bone specialist (orthopedic surgeon) or a hand specialist to ensure that the broken bone mends properly. The hand specialist may be either an orthopedic surgeon or a plastic surgeon who specializes in hand injuries.
- Follow-up should occur within one week of the initial injury if there is not a critical amount of angulation. If angulation of the fracture exceeds acceptable levels, follow-up should occur sooner.
- If a plaster splint is placed in on the fracture in the doctor's office, or in the emergency department, and the patient develops increased pain or numbness in the fingers, or if the fingers become cold and blue, then loosen the splint, notify the doctor, and return to the emergency department immediately.
What Is the Recovery Time and Prognosis for Boxer's Fracture?
With proper immobilization of the broken bones and good follow-up with a hand specialist, most people with a boxer's fracture have a good prognosis. Those who require surgery often have a longer period of recovery than people who only require splinting. Some will require physical therapy after the splint is removed because the muscles become weakened from not being used.
Can You Prevent Boxer's Fracture?
The key to preventing boxer's fractures is to avoid situations in which the injury can occur. Boxer's fractures most commonly occur during fist fights and when someone punches a hard object in anger or frustration. Avoiding these situations can reduce significantly the risk of sustaining a boxer's fracture. In addition, decreasing the loss of bone that occurs naturally with age also is critical. This can be accomplished with regular exercise and calcium supplements or adequate intake of dairy products.
