Pain at the base of the fingers? It could be a (Metacarpal Fracture)!

Have you ever fallen and banged your hand on the floor, or hit it against a wall in anger, and then felt a sharp pain in your hand, swelling, and difficulty moving your fingers? If so, you may have broken a bone at the base of your fingers. Doctors call this a `(Metacarpal Fracture)`. Don't worry, let's talk about this simply.

What is this `(Metacarpal Fracture)`?

Simply put, a `(Metacarpal Fracture)` is a break in a bone in your hand. Now you may be wondering what `(Metacarpals)` are. Your hand has five long bones that connect the small bones of your fingers (also called `Phalanges`) and the wrist. Those bones are called `(Metacarpals).` If you touch the back of your hand, you will be able to feel these bones.

This type of fracture is a very common injury . It most often occurs when the hand is twisted or falls, or as a result of an accident while playing sports. Sometimes, it can also occur after a severe blow to the hand.

The best part is that most metacarpal fractures do not require major surgery. You can simply use a splint or cast to immobilize your hand and wait for the bone to heal. However, some serious fractures may require surgery.

What are the `(Metacarpal)` bones in our hands?

We have five metacarpal bones in each hand. These are like the bases for our five fingers. Doctors call them by numbers. Starting from the thumb side and moving towards the little finger side:

• First Metacarpal: This is connected to your thumb.
• Second Metacarpal: The bone that connects to the thumb.
• Third `(Metacarpal)` bone: The bone that connects to the middle finger.
• Fourth `(Metacarpal)` bone: The bone that connects to the index finger (ring finger).
• Fifth `(Metacarpal)` bone: The bone that connects to the little finger.

Each of these bones is very important for the function of our hand.

How is a `(Metacarpal Fracture)` classified?

When you go to a doctor, they will examine your arm, possibly take an X-ray, and classify the fracture. This classification is based on which bone is broken, the shape of the fracture, how it happened, and whether the bone is protruding through the skin.

Types according to the shape of the fracture

Some fractures are classified according to the shape of the line that the bone breaks:

• `(Transverse fracture)`: A transverse break in the bone.
• Oblique fracture: A bone fracture that occurs at an angle.
• Spiral fracture: A fracture in which the bone breaks in a spiral, like a screw.
• Segmental fracture: A bone that breaks in two places, with a piece in the middle separated.
• `(Comminuted fracture)`: A fracture in which the bone is crushed into many pieces.
• Buckle fracture: Common in young children, one side of the bone appears to be slightly bruised, but does not break completely.
• `(Hairline fracture)`: The bone appears to be slightly cracked.

Types according to the way the break occurred

• `(Compound fracture)`: This is what we've been talking about before, where the bone breaks and comes out through a hole in the skin. This is a bit dangerous, because there's a greater chance of germs entering.
• `(Stress fracture)`: Similarly, when a bone is subjected to prolonged stress or pressure, small bruises appear.
• Avulsion fracture: A tear in a tendon or ligament that is attached to a bone, causing a piece of bone to come off with it.

Is the bone protruding through the skin? (`Open vs. Closed Fractures`)

This is also very important.

• `(Open fracture)` (Open fracture): Here , the broken bone is visible through the skin . In such cases, treatment should be sought immediately. Because there is a high chance of germs entering the wound and causing infections (`infections`). It also takes longer to heal.
• `(Closed fracture)`: Here the bone is broken, but the skin is not broken, and the bone is not protruding. This can also be serious, but the risk of infection is lower than an `(Open fracture)`.

Are the bones displaced? (`Displaced Metacarpal Fractures`)

Doctors will call your fracture "displaced" or "non-displaced."

• `(Displaced fracture)`: This means that after a bone breaks, the two broken pieces are separated from each other, leaving a gap between them. It's like two pieces of broken plate being pushed back and forth. These types of fractures often require surgery to fix .
• `(Nondisplaced fracture)`: Here the bone is still broken, but the broken pieces are not that far apart, they are mostly in the same line.

Where a Metacarpal Bone Can Break

Any part of this `(Metacarpal)` bone can break. There are four main parts:

• Base: This is the end of the bone farthest from the fingers, where it connects to the bones of the wrist.
• Shaft: The long part in the middle of the bone.
• Neck: The part where the stem and head connect.
• Head: The end of the bone that connects to the fingers. This is what makes up the "knuckles" that protrude forward when we clench our fists.

Specific Types of Metacarpal Fracture

Boxer's Fracture

This is the most common type of metacarpal fracture . One in four metacarpal fractures is this type. This is a break in the neck of the metacarpal bone (the fifth bone) that connects to the little finger.

As the name suggests, it often occurs when the hand is hit with a hard object . For example, it can happen when you hit a wall in anger, or when a boxer throws a wrong punch. That's why it's called a ``Boxer's fracture''.

Bennett and Rolando Fractures

These are fractures that affect the joint at the base of the metacarpal bone (the first) of the thumb. These are a bit more complicated and will likely require surgery .

Who is more likely to develop these `(Metacarpal Fractures)`?

Anyone can break a bone in their hand like this. However, some groups are at higher risk:

• People between the ages of 10 and 40: Because people in this age group are active, they are more likely to experience sports accidents and falls.
• Men: This may be because men are generally more physically active and engage in risky activities than women.
• Women over 50: At this age, especially after menopause, the risk of developing osteoporosis (bone loss disease) is higher, causing bones to become weak and break easily.

How common are `(Metacarpal Fractures)`?

These are very common . In fact, they are the third most common type of fracture. Metacarpal Fractures account for 10% of all fractures!

Metacarpal fractures are the most common hand injury, especially in young people between the ages of 18 and 34.

How does a `(Metacarpal Fracture)` affect my body?

In addition to symptoms like pain and swelling, a metacarpal fracture can make it very difficult, if not impossible, for you to use your hand normally.

You should avoid using your hand as much as possible until it heals. Talk to your doctor about what you should avoid and how long you should be careful. Putting weight on your hand before the bone heals properly can damage the bone again and cause further complications.

What are the symptoms of a `(Metacarpal Fracture)`?

You may have one or more of these symptoms:

• Severe pain: Especially when touching or shaking the hand.
• Swelling: The broken part of the hand swells.
• Tenderness: The fractured area hurts when touched .
• Difficulty moving or using the hand.
• Bruising: Sometimes blood clots can cause the skin to turn blue.
• A change in the shape of the hand or something like a lump: An unusual lump or bend may be visible on the hand.

If a metacarpal bone breaks, other tissues around it may also be damaged. These include:

• Ligaments
• Tendons
• Muscles

What are the causes of `(Metacarpal Fractures)`?

This is often caused by:

• Falls: A major cause of falls is slipping on the ground.
• Sports accidents: Accidents that occur while playing cricket, rugby, or any other sport.
• Other emergencies: Things like car accidents.
• Accidents at the workplace:In places where work is done, such as construction.

Sometimes, a metacarpal fracture is more likely to occur due to other health conditions that affect the fingers. For example, a type of non-cancerous tumor called an enchondroma can weaken the bone and cause it to break.

Osteoporosis and fractures

If your bones are weak due to a condition called osteoporosis, you are at a much higher risk of breaking a bone.

Osteoporosis causes bones to become thin, weak, and can break suddenly and unexpectedly. Many people don't know they have osteoporosis until they break a bone! This is because it doesn't show obvious symptoms at first.

Women over the age of 50 are at increased risk of developing osteoporosis. It is a good idea to talk to your doctor and get a bone density test. This can help detect this condition before a bone breaks.

How to recognize a `(Metacarpal Fracture)`?

Your doctor will examine your hand and may also perform several imaging tests.

Often, a doctor will be able to tell if there is a fracture just by looking at the hand. However, an imaging test is needed to confirm exactly which bone is broken and what type of fracture it is.

What kind of tests are done?

Usually one or more of these tests are done:

• `(X-ray)` (X-ray test): This is mainly used to check whether there is a fracture and how much damage the bone has sustained.
• `(Computed Tomography) (CT) scan` (CT scan): This can produce a clearer, three-dimensional (`3D`) image than an `(X-ray)`. The doctor /surgeon can get a better idea of ​​not only the bones, but also the surrounding tissues.
• Bone Density Test: Sometimes called a DEXA scan, this helps to detect osteoporosis.

How to treat a `(Metacarpal Fracture)`?

The treatment you receive will depend on the type of fracture you have, how it happened, and how much damage has been done to the bones.

Immobilization of the hand

If your fracture is not too severe, meaning the bones are not too far apart (a `nondisplaced fracture`), you will need to rest in a `splint` or `cast` for a few days . Most people will need to keep their arm immobilized for three to six weeks. During this time, they will take X-rays to make sure the bones are healing properly.

`(Closed Reduction)` (Closed Reduction)

For more severe fractures, where the bones are far apart, the doctor may need to use his hands and apply external pressure to ``set`` the broken bone back into place . This is called a ``closed reduction``. To avoid pain while doing this, he may use one of these methods:

• A local anesthetic is given to numb only the fracture site.
• Sedatives are given to relax the entire body.
• Otherwise, you will be given general anesthesia to put you completely to sleep.

After a closed reduction, your hand will be put in a splint or plaster.

`(Metacarpal Fracture)` Surgery (`Surgery`)

Some metacarpal fractures require surgery . Depending on the type of fracture and the extent of damage to the bones, your surgeon may use different techniques.

Internal Fixation

What happens in this is that the surgeon `sets` the broken pieces of your bone and fixes them in place. That's when the pieces of bone fit together properly and heal. Most often, this is done through something called ``internal fixation.`` That is, the surgeon inserts metal devices inside your bone and fixes the bone.

Things used for this:

• Plates and screws: Metal plates are placed on the bone, secured with screws, and the broken pieces are held together.
• Pins (or K-wires): Small pieces of bone (too small to be fixed by other methods) are held in place using small pins made of stainless steel.

Most of the time, these metal pieces stay in the body for life. However, sometimes, especially if pins are inserted, you will have to have another minor surgery to remove the pins after the bone heals.

Joint replacement (`Arthroplasty`)

If you have a broken or severely damaged joint in your hand, you may need to have an arthroplasty (joint replacement). This involves removing the damaged joint and replacing it with an artificial joint. However, this is rarely necessary for a metacarpal fracture.

Bone Grafting

If your metacarpal fracture is severely displaced, comminuted, or has problems with the bone not healing properly, you may need to have a bone graft. This involves the surgeon taking extra bone tissue and grafting it into the broken area to help the bone heal. Then, they usually perform an internal fixation to hold the pieces together until new bone grows.

There are several ways to obtain tissue for this bone graft:

• From somewhere else on your own body – most often above the hip bone.
• From another donor (`external donor`).
• An artificial replacement piece.

After surgery, your arm will be immobilized. You will be given a splint or cast, and only then will you be able to start using your arm again. You may also need to undergo occupational therapy to regain normal range of motion.

What medicine is used for a `(Metacarpal Fracture)`?

To reduce pain, you can usually get over-the-counter medications like ``NSAIDs'' (e.g. ``Aspirin'', ``Ibuprofen'') and ``(Acetaminophen)'' (e.g. ``Paracetamol'') which can cause bleeding after surgery. Therefore, your surgeon will tell you exactly which painkillers are right for you. It is very important to take the medication exactly as he or she tells you.

Metacarpal Fracture and its Treatment Complications

Whether surgery is performed or not, complications can sometimes occur. Some of them are:

• `(Malunion)`: This is when broken bone pieces fit together incorrectly (like a fist).
• `(Nonunion)`: The bones not fitting together properly, or not fitting together at all.
• Bone infection (Osteomyelitis): If you have had an open fracture (one where the bone has broken through the skin), you are at higher risk of developing a bacterial infection.
• Stiffness in the hand: People who have had a metacarpal fracture usually feel stiffness around the fracture site. This stiffness can be reduced with home exercises and occupational therapy.
• Acute Compartment Syndrome (ACS): This is a serious condition. The pressure inside the muscle increases, blood flow is disrupted, and tissue damage can occur. This can lead to permanent damage to the nerves and muscles.

Important: If you suddenly experience unbearable pain, swelling, numbness, or a change in color in your hand, see a doctor immediately.

How soon will I feel better after treatment?

It may take several weeks for your symptoms to subside. The pain will start to subside within a few days. However, it will take about six weeks for the bone to fully heal.

Depending on the type of treatment you received (a splint, a cast, or surgery), the time it takes for you to start moving your arm again will vary. It usually takes a few weeks.

If you continue to have severe, unbearable pain, let your doctor know immediately.

How to reduce the risk of `(Metacarpal Fracture)`?

Follow these general tips to protect yourself from accidents:

• Always wear your seat belt when riding in vehicles.
• Wear proper safety equipment when playing sports or doing risky work.
• Keep your home and workplace tidy by removing items that could cause you to slip or trip.
• When picking up something from above, use a suitable device (like a ladder) instead of climbing on chairs or tables.
• Follow a diet and exercise plan that helps maintain good bone health.
• If you are over 50 years old, or if someone in your family has osteoporosis, talk to your doctor about a bone density test.
• If you have difficulty walking or are at high risk of falling, use a cane or walker.

What can I expect if I have a `(Metacarpal Fracture)`?

Even if you break a `(Metacarpal)` bone, you can most likely make a full recovery.

You will need to undergo occupational therapy to regain strength and movement in your hand. This will greatly help you to continue working normally.

How long does it take for a `(Metacarpal Fracture)` to heal?

The recovery time will vary depending on the severity of your fracture and the treatment you received. Most people can recover within a month or two.

However, everyone's body heals differently. Ask your doctor or surgeon how long it will take to heal, depending on your situation.

Will I be unable to go to work/school?

You may not be able to go to work or school until your hand heals, especially if it is your dominant hand (such as the hand you use most often).

Most people can return to physical activities like sports after about eight weeks. However, you should always check with your doctor before starting such activities again.

When should I go to the emergency room?

If you think you have a metacarpal fracture or other broken bone in your hand, you should see a doctor as soon as possible. Go to an emergency room immediately, especially if you have any of these symptoms:

• Very severe pain.
• If you can't move your hand or fingers normally.
• If the appearance of your hand has changed significantly (like it has become stretched or has a lump).
• If you can see the bone through the skin.
• If your hand has recently turned blue along with these symptoms.

If you have suffered a major accident (trauma), go to a hospital immediately.

What questions should I ask my doctor?

When you go to see the doctor, it's helpful to ask these questions:

• What type of fracture do I have?
• Will I need surgery?
• How long will it take to heal?
• When will I be able to play sports and engage in physical activity again?

Breaking a bone in your hand can be really frustrating, especially when it interferes with your daily activities (like writing or holding your phone). But remember, even if you need surgery, you can make a full recovery from a `(Metacarpal Fracture)`.

Finally, remember this (Take-Home Message)

A metacarpal fracture, also known as a broken bone at the base of the finger, can happen to anyone. It can be caused by a fall, a sports accident, or a sudden blow.

The most important thing is to seek medical advice immediately if you suspect you have this type of injury. The doctor will examine you, take an X-ray if necessary, and give you the most appropriate treatment. This may include putting on a cast or minor surgery.

Remember, with proper treatment and rest, most people make a full recovery and are able to use their hand normally again. So, don't panic. Follow your doctor's instructions exactly.

If you think you might be at risk for osteoporosis (especially if someone in your family has it), talk to your doctor about it. Getting a bone density test can help detect the condition before a bone breaks.
