Broken Finger

Overview

A broken finger is a crack or break in one of the three small bones that make up a finger. It is a common injury that usually heals well with the right care.

Yes, broken fingers are one of the most common bone injuries seen in general practice and emergency care.

They can happen to anyone, but they are especially common in people who play contact sports, and in older adults with weaker bones.

Symptoms

Common symptoms

• Pain or tenderness in the finger
• Swelling, bruising, or a lump on the finger
• Difficulty bending or straightening the finger
• A finger that looks out of place or bent at an odd angle

Symptoms in children

• A child may cry, hold the hand, or refuse to use that hand
• Swelling and bruising may be smaller than in adults but are still possible
• The finger may look slightly different from the other one

Symptoms in older adults

• Pain may be less intense than in younger people
• Swelling and bruising can be mild, even with a break
• Older adults may have low bone density, which makes fractures more likely

Causes

Main causes

• Falling onto an outstretched hand
• Striking the finger against a hard object, such as a ball or door
• A direct blow or crush injury, like slamming a finger in a door

Risk factors

• Playing contact sports like football or basketball
• Having osteoporosis or another condition that weakens bones
• Working with tools or machinery that could crush or hit the fingers
• Older age, because bones naturally become weaker

When to see a doctor

See a doctor urgently if:

• A visible bump or crooked finger
• Numbness, tingling, or a fingertip that looks pale or blue
• An open wound or break in the skin near the damaged finger

Book a routine appointment if:

• Persistent pain, swelling, or stiffness in a finger
• You are not sure whether the finger is broken or just sprained
• The pain does not improve with rest and ice after a few days
• You have a history of broken bones or weak bones

Diagnosis

A doctor will ask how the injury happened, then examine your finger for swelling, tenderness, and movement. They may also compare it with your other hand.

Tests that may be done

• An X-ray of the finger to see if a bone is broken and how well the pieces are lined up
• In rare cases, if the injury is complex, a doctor may request a CT scan or an MRI to see the soft tissues and joints in more detail

What to expect at your appointment

The examination may be uncomfortable, but it is usually quick. You may need to have the X-ray before the doctor explains your treatment. The doctor will tell you whether the finger can be treated with a simple splint or whether further help is needed.

Treatment

Most broken fingers are treated without surgery. The main goals are to keep the broken pieces in the right position and to let the finger heal properly.

Self-care at home

• Rest the finger and avoid using it for everyday tasks
• Apply an ice pack wrapped in a cloth for about 15 to 20 minutes at a time to reduce swelling
• Keep the hand raised to the level of the heart or above when possible to ease swelling
• Do not try to straighten the finger yourself if it looks bent

Medical treatments

Your doctor or pharmacist may recommend a suitable painkiller. They may also fit a splint or a plaster cast to hold the finger steady while it heals. In some cases, the doctor may place the injured finger next to a healthy finger and tape them together (called buddy taping) to provide support.

When is surgery considered?

Surgery may be needed if the fracture is severe, the bones are very out of place, the break is open, or the injury damages a tendon or ligament. During surgery, the doctor may use small pins or plates to hold the bone in the correct position.

Living with this condition

While your finger heals, you will need to protect it from further injury. You might find it useful to use your other hand more often, and to choose clothing with generous sleeves or pockets so the cast or splint fits comfortably.

Lifestyle tips

• Avoid activities that require gripping, bending, or heavy use of the injured hand until your doctor says it is safe
• Wash the skin around a cast or splint carefully to avoid moisture
• Keep the splint or cast dry and do not remove it unless your doctor tells you to

Diet and exercise

Eating a balanced diet that includes calcium and vitamin D helps bones repair, although supplements are not necessary for everyone. Light exercise that does not involve the injured hand can help keep your body healthy, but avoid running or contact sports until your finger has healed.

Mental health and emotional wellbeing

Having a finger injury can be frustrating, especially if it affects your work or hobbies. It is normal to feel a little down while you recover. If you feel anxious or hopeless, talk to your doctor or a trusted friend.

Prevention

You cannot always prevent a broken finger, but you can reduce the risk. Wearing protective gloves or hand guards during contact sports and using proper safety equipment around tools can help. Keeping your home free of trip hazards may also prevent falls that lead to hand injuries.

Vaccines

There is no vaccine that prevents a broken finger.

Screening programmes

There is no routine screening test for broken fingers. However, if you have a condition that weakens your bones, your doctor may recommend bone density testing.

Complications

If left untreated

• A broken finger that is not treated may heal in a wrong position, causing a permanent bump or deformity
• It may lead to lasting stiffness or difficulty bending the finger
• Untreated infections can develop if the break is open and bacteria enter the wound
• In severe cases, nerve or tendon damage can limit how well you can use the hand

Long-term outlook

With proper care, most broken fingers heal completely without lasting problems. Full healing can take a few weeks to a couple of months, and a hand therapist can help if movement is slow to return. The outlook is generally very good, especially when treatment begins soon after the injury.
