Broken Hand

A broken hand, also known as a hand fracture, means one or more of the 27 bones in your hand has cracked or broken. This common injury often results from falls, sports accidents, or direct blows. Symptoms usually include severe pain, swelling, bruising, and difficulty moving your hand or fingers. Prompt medical attention is important for proper diagnosis and treatment to ensure good healing.

What is Broken Hand?

A broken hand, medically called a hand fracture, occurs when one of the many bones in your hand cracks or breaks. Your hand contains 27 small bones, including the wrist bones (carpal bones), the long bones in your palm (metacarpal bones), and the finger bones (phalanges). Any of these bones can break, leading to pain and difficulty using your hand.

The human hand is a complex structure made up of many small bones that allow for a wide range of motion and dexterity. There are eight carpal bones in the wrist, five metacarpal bones forming the palm, and 14 phalanges that make up your fingers and thumb. A fracture can happen in any of these bones. Some hand fractures are small cracks, while others involve a complete break where the bone is separated into two or more pieces. The severity of a broken hand depends on which bone is affected, the type of break, and whether the bone pieces are still aligned (nondisplaced) or have shifted (displaced).

Symptoms

If you have a broken hand, you will usually experience immediate and severe pain, especially when trying to move your hand or fingers. Other common symptoms include noticeable swelling, tenderness to the touch, and bruising around the injured area. You might also find it difficult or impossible to move your fingers, or your hand may appear deformed.

The pain from a broken hand is often sharp and worsens with movement. Swelling can develop quickly, making your hand look puffy and feel tight. The injured area will likely be very tender if you press on it. Bruising may appear shortly after the injury or develop over a few days. In some cases, a broken hand can cause an obvious deformity, such as a finger that looks crooked or out of place. You might also experience numbness or stiffness in your fingers, or have trouble gripping objects. It is important to note that sometimes a severe sprain can have similar symptoms to a broken bone. However, a broken bone typically causes more intense and persistent pain, and often prevents you from using your hand normally.

Causes & risk factors

Broken hands are most often caused by direct trauma, such as falling onto an outstretched hand, sports injuries, or direct blows to the hand. Car accidents can also lead to hand fractures. Certain factors can increase your risk of breaking a hand, including having weakened bones or participating in high-impact activities.

Common causes of hand fractures include accidental falls, especially when you try to catch yourself with an outstretched hand. Sports injuries, particularly in contact sports like football or hockey, or activities involving falls like skiing or skateboarding, frequently result in broken hands. Direct impacts, such as punching a hard object (sometimes called a "boxer's fracture" when it affects the fifth metacarpal bone near the pinky finger), or crush injuries, can also cause bones to break. Car accidents are another significant cause of severe hand fractures. Certain risk factors can make you more prone to a broken hand. For example, people with osteoporosis, a condition that causes bones to become weak and brittle, are at a higher risk of fractures from even minor trauma. Participating in contact sports or activities with a high risk of falls also increases your chances of experiencing a hand fracture.

How it's diagnosed

Diagnosing a broken hand typically begins with a physical examination by a doctor, who will check for tenderness, swelling, and any deformities. To confirm the diagnosis and determine the exact location and type of fracture, X-rays are usually taken. In some complex cases, other imaging tests like a CT scan or MRI may be needed.

During the physical examination, your doctor will carefully inspect your hand, looking for visible signs of injury such as swelling, bruising, or an abnormal shape. They will gently feel your hand to locate areas of tenderness and assess your range of motion and sensation in your fingers. An X-ray is the most common and effective way to diagnose a broken hand. It provides clear images of the bones, allowing the doctor to see if a fracture is present, its exact location, and how severe it is. Multiple X-ray views are often taken to get a complete picture of the injury. For more complex fractures, such as those involving a joint or multiple bone fragments, your doctor might order a computed tomography (CT) scan. A CT scan provides more detailed, cross-sectional images of the bones. Magnetic resonance imaging (MRI) may be used if there is concern about damage to soft tissues, such as ligaments or tendons, in addition to the bone injury.

Treatment options

Treatment for a broken hand depends on the severity and type of fracture, but the main goal is to ensure the bones heal correctly. Many simple fractures are treated non-surgically with immobilization, using a cast or splint to hold the bones in place while they heal. More severe breaks may require surgery to realign and stabilize the bone fragments.

For most broken hands, non-surgical treatment is effective. This typically involves immobilizing the hand with a cast, splint, or brace. This keeps the broken bones from moving, allowing them to heal properly. Your doctor will choose the best type of immobilization based on the fracture's location and stability. Pain relievers, such as over-the-counter medications, can help manage discomfort. If the broken bone pieces are out of alignment (displaced), your doctor may need to perform a procedure called reduction. This involves gently manipulating the hand to realign the bone fragments without surgery. After reduction, a cast or splint is applied to maintain the correct position. Surgery may be necessary for severe fractures, such as those that are significantly displaced, unstable, involve a joint, or are open fractures (where the bone breaks through the skin). During surgery, pins, plates, or screws may be used to hold the bone fragments together securely while they heal. This internal fixation helps stabilize the fracture and ensures proper alignment.

Recovery & outlook

Recovery from a broken hand typically takes several weeks to months, depending on the fracture's severity and location. Most people regain full or near-full function with proper treatment and rehabilitation. Physical therapy is often a crucial part of recovery to restore strength, flexibility, and range of motion, helping you return to your normal activities.

The initial healing period, during which your hand is immobilized in a cast or splint, usually lasts about three to six weeks. After the cast is removed, your hand and fingers may feel stiff and weak. Swelling and some aching can also persist for a longer period. Physical therapy or occupational therapy is often recommended to help you regain full use of your hand. A therapist will guide you through specific exercises to improve your hand's strength, flexibility, and range of motion. Following these exercises diligently is vital for a successful recovery. While most broken hands heal well, some people may experience long-term stiffness, weakness, or occasional aching. Complications such as nerve damage, blood vessel damage, or arthritis in the affected joint are rare but possible. Your doctor will discuss your specific outlook and any potential complications based on your injury.

When to see a doctor

You should see a doctor immediately if you suspect you have broken your hand, especially if you experience severe pain, noticeable swelling, or a visible deformity. Urgent medical attention is also needed if you cannot move your fingers, have numbness, or if the injury causes an open wound where bone might be exposed.

Do not try to self-diagnose or delay seeking medical care for a suspected broken hand. Prompt diagnosis and treatment are crucial to ensure the bone heals correctly and to prevent potential long-term problems, such as chronic pain or permanent stiffness. If your hand or fingers appear crooked, bent at an unusual angle, or if you have an open wound near the injury, seek emergency care. These signs suggest a more severe fracture that requires immediate attention. Even if the pain is not extreme, but you have persistent swelling, tenderness, or difficulty using your hand after an injury, it is best to have it checked by a doctor. Early intervention can significantly improve your recovery outcome.

Frequently asked questions

How long does it take for a broken hand to heal?

The healing time for a broken hand varies depending on the specific bone broken and the severity of the fracture. Generally, bones take about three to six weeks to heal enough for the cast or splint to be removed. Full recovery, including regaining strength and flexibility through physical therapy, can take several months.

Can you move your fingers if your hand is broken?

Whether you can move your fingers with a broken hand depends on the location and type of fracture. If the break is in the finger bones (phalanges) or affects the tendons, movement might be very painful or impossible. However, some people with a broken hand, especially in the palm (metacarpals), may still be able to move their fingers, though it will likely be painful and limited. Always seek medical advice if you suspect a break.

What is a "boxer's fracture"?

A "boxer's fracture" is a common type of broken hand that specifically refers to a break in the neck of the fifth metacarpal bone, which is the long bone in your palm leading to your pinky finger. It often occurs when punching a hard object with a closed fist. While it's called a "boxer's fracture," it can happen to anyone who sustains this type of injury.

Will I need surgery for a broken hand?

Not all broken hands require surgery. Many simple, stable fractures can heal well with non-surgical treatments like a cast or splint to immobilize the hand. Surgery is typically considered for more severe fractures where the bones are significantly displaced, unstable, involve a joint, or if there are multiple breaks. Your doctor will determine the best treatment plan based on your specific injury.

What is the difference between a broken hand and a sprained hand?

A broken hand involves a crack or break in one of the bones, while a sprained hand involves damage to the ligaments, which are the tough tissues connecting bones. Both can cause pain, swelling, and difficulty moving. However, a broken hand often presents with more severe pain, tenderness directly over the bone, and sometimes a visible deformity. An X-ray is needed to distinguish between the two.

What should I do immediately after breaking my hand?

Immediately after a suspected broken hand, you should try to keep your hand still and avoid moving it. You can apply ice to the injured area to help reduce swelling and pain. Elevating your hand above your heart can also help with swelling. Seek medical attention as soon as possible to get a proper diagnosis and start treatment.
