Metacarpal Fracture

Past Scott Kaar, M.D.

A metacarpal fracture or broken metacarpal is a fracture (break) of the tubular bones within the palm (metacarpals). They classically occur in the small finger or metacarpal bone in boxers or athletes of other sports or activities. This blazon of fracture has therefore become to be known equally a "boxer'due south fracture." Each of the digits of the mitt has a corresponding metacarpal bone associated with it, and any of these metacarpals may be fractured during a high free energy touch to an athlete'southward paw.

These injuries are as well mutual in other sports besides battle. For example Ronnie Brownish of the Miami Dolphins and Tony Romo of the Dallas Cowboys each spent fourth dimension on the IR from suffering a metacarpal fracture as did the Mavericks Jason Terry who had surgery to prepare his metacarpal fracture.

Anatomy of Metacarpal

The metacarpals are the tubular bones that comprise near of the space in the palm. Each of the fingers (digits) has a corresponding metacarpal that links the wrist basic to the phalanges (private basic of the fingers). $metacarpal fractures$ There are flexor tendons on the palm side of the metacarpals that deed to flex, or bend the fingers as in making a fist. There are extensor tendons on the back of the hand that human activity to extend or straighten the fingers. In between the metacarpal bones are the small intrinsic muscles (the interosseous and lumbrical muscles) that farther help to control fine finger motility. When a metacarpal fracture happens, the finger flexors and the intrinsic muscles act together to bend the fracture toward the palm (apex dorsal angulation). How much the fracture bends is somewhat dependant on how much force caused the injury in the first place. A college force injury can lead to more than bending (displacement of the fracture).

In an athlete's normal uninjured hand, there is less motion at the joints of the alphabetize and long finger and more motion at the ring and small fingers. The increased motion at the two smaller fingers allows for more than angulation to exist adequate equally the fracture heals. This is because the increased normal movement of these two metacarpal bones can allow the mitt to adapt to any permanent deformity. On the other hand, the index and long fingers' have lesser ability to adapt to metacarpal fracture bending because they have less natural motion. The normal move of the metacarpals can be seen when i makes a tight fist while watching the ring and pocket-size finger side of the back of the mitt bend further inward.

Metacarpal Fracture Symptoms

An injured athlete will describe a forceful blow to the manus. It will oftentimes be due to a punching injury or a directly blow from a fall or crush injury. Their hand will be very painful, maximally so over the specific metacarpal bone that is fractured. There will exist swelling, often a considerable corporeality, likewise as bruising direct over the injury. They may have difficulty moving the fingers due to the amount of pain from the fracture.

On physical examination, the athlete's hand volition be most tender over the injured metacarpal. At that place may exist palpable fracture ends of the os which can exist felt to motion if pressed. If the fracture becomes angled, so the hand may be bent inwards towards the palm some and there may be a point felt from the noon of the fracture. One important aspect of the physical exam is whether there is a rotational deformity of the fracture. This tin be assessed by asking the patient to make a fist. When they practice so, the fingers should all line up properly and be parallel. If the finger corresponding to the fractured metacarpal does not line up properly with the surrounding fingers, then the fracture ends are nearly likely rotated. When this happens, often the injured finger will scissor under or in a higher place an adjacent finger.

A metacarpal fracture can occur in whatsoever sport although the highest risk is in those sports where there is a risk of a loftier energy bear on occurring to the athlete's mitt. Classically this occurs in boxers and other athletes involved in the martial arts. However other impact sports like football and rugby identify the competitor's hands at risk of impact against things like opposing players' helmets and pads also as the footing itself.

Causes

A metacarpal fracture occurs when the hand strikes another object with sufficient force to cause the metacarpal bones to break. This ordinarily occurs during a dial with a clenched fist. In doing so, the knuckles (the heads of the metacarpals) strike straight against a hard object and all the force of the accident is transmitted directly through the metacarpals. This explains why boxers are susceptible to these fractures, especially when someone throws a punch without the protection of gloves. A crush injury to the hand can likewise cause a metacarpal fracture such every bit if someone lands directly on the athlete'due south manus.

Metacarpal Fracture Treatment

Splint for metacarpal fracture

A gutter splint or cast should be used to immobilize a metacarpal fracture. A gutter splint may be modified based on the location of the injured finger. An ulnar gutter splint, too subsequently called a "boxer splint", should be used for fourth or fifth metacarpal fractures leaving the thumb, alphabetize, and ring fingers gratis. A radial gutter splint should be used for 2d or third metacarpal fractures, with a hole for the thumb while leaving the ring and fiddling finger costless.

Initial treatment involves using a metacarpal fracture splint on the hand. In doing so, the hard splint does non circumferentially surround the hand and forearm, rather some of the circumference is but a soft wrap to let for swelling to occur. The fingertips volition be usually out of the splint and left gratis to allow them some motility and to non get stiff.

Subsequently treated

After a closer exam and radiographs are performed, the next decision is whether or not surgery is necessary. In the great bulk of cases, the fracture is lined up sufficiently and there is not too much deformity of the os ends. More deformity can be accepted in the ring and small finger without needing surgery because these fingers accept a greater compensatory capability considering they have more motion than the index and long fingers. Any pregnant scissoring is unacceptable to be treated airtight as this deformity is poorly tolerated even after the fracture heals.

If the metacarpal fracture is indeed lined up within an acceptable range, then the patient'due south metacarpal fracture splint is inverse to a hard circumferential bandage in many cases. In some cases where the fracture is not displaced (shifted) at all or very niggling, a removable splint can be considered, even so the athlete accepts a adventure of the fracture bone ends shifting further especially if the hand is impacted a second fourth dimension. In most cases, the metacarpal fracture heals well and does so over the course of vi to viii weeks. Over that time the cast tin can be removed afterward a period of time and changed to a removable splint. X-rays are checked every few weeks to be sure the fracture is healing properly and the bone ends maintain their alignment.

When to See the Dr.

Hundreds of athletes sustain acute injuries every mean solar day, which tin be treated safely at dwelling using the P.R.I.C.E. principle. Just if there are signs or symptoms of a serious injury, emergency offset aid should be provided while keeping the athlete at-home and still until emergency service personnel go far. Signs of an emergency situation when you should seek intendance and dr. treatment can include:

Os or articulation that is clearly deformed or broken
Astringent swelling and/or pain,
Unsteady animate or pulse
Disorientation or confusion
Paralysis, tingling, or numbness

In add-on, an athlete should seek medical care if acute symptoms exercise not get away afterwards rest and home treatment using the P.R.I.C.Eastward principle.

What imaging is necessary for a metacarpal fracture?

Definitive diagnosis of a metacarpal fracture requires a series of hand radiographs to clearly evaluate the paw basic including the metacarpals. In sure cases where the fracture needs to be seen in greater particular, a CT scan can exist considered, merely this is highly unusual. Other imaging tests like an MRI are almost never needed for an isolated metacarpal fracture as they normally don't add any further information beyond a regular x-ray. If other injuries are suspected, merely not seen conspicuously on the x-rays, and then further tests could exist considered.

Is metacarpal fracture surgery needed?

Operative stabilization is necessary for metacarpal fractures where there is besides much angle (angulation) or displacement at the fracture site. Normally around 15° is the maximum amount of angulation tolerated in the alphabetize and long finger metacarpals, while 35° is adequate for the band finger, and 50° is ofttimes tolerated in the small finger. Also, if scissoring is present indicating unacceptable rotation of the fracture ends, and so fixation should be considered. Sometimes an attempt at realigning the fracture (airtight reduction) is possible without an incision. If successful, the patient tin be treated in a cast as outlined above.

Other less common reasons for surgery include a fracture where the overlying peel is broken and the wound communicates with the fractured bones (open fracture). In this case, surgery is often required to clean out the wound to subtract the adventure of an infection. In those injuries, the fractured metacarpal may be unstable considering the soft tissue surrounding the bones is often worse injured and therefore provides less stability to the fracture. Lastly, in rare cases in that location may exist a tendon laceration that occurs at the aforementioned time every bit the metacarpal fracture. In these injuries, the fracture is often stock-still at the same time as the tendon is repaired.

Metacarpal fracture surgery

An injured athlete with a metacarpal fracture that requires operative stabilization is taken to the operating room and either sedated or placed nether general anesthesia to relax the patient and allow the fracture to be manipulated. Sometimes the fracture ends can exist realigned and pinned without a large incision. Many times however an incision is needed and direct visualization of the fracture ends is achieved. The fracture is realigned (reduced) under straight visualization and and so stock-still in place with pins, screws or plates and screws (open reduction internal fixation). Then the fracture is immobilized for a menstruation of time to protect the incision and the fracture.

Recovery time for metacarpal fracture

Following a metacarpal fracture treated operatively or non-operatively, the patient's hand and wrist are immobilized in a splint, bandage or sometimes a removable splint as it heals. Radiographs are taken periodically to be sure that the fracture maintains its proper alignment and continues to heal. Metacarpal fractures usually take few months to heal, merely the verbal timing of an athlete's return to their sport depends on how stable the fracture is and how much risk of re-displacing the fracture, the athlete, and treating physician feels comfy with. In some sports, the athlete can train or compete even with a cast on such every bit running while others similar swimming are virtually impossible to participate in until a splint or cast is no longer worn. Sometimes in collision sports like football, an athlete can compete with a protective removable splint while the fracture continues to heal although this is usually merely possible for certain positions like lineman and defenders considering they don't rely as much on holding onto the ball.
