Broken Leg

Overview

A broken leg is a crack or break in one of the bones in your leg. This can happen in the thigh bone, shin bone, or the bone at the front of your lower leg. It is also called a leg fracture.

Yes, broken legs are fairly common. They can happen at any age, from everyday falls, sports injuries, or accidents.

Anyone can break a leg, but it happens more often in active children, athletes, and older adults with weaker bones or balance problems.

Symptoms

Common symptoms

• Pain that gets worse when you move or put weight on the leg
• Swelling, bruising, or tenderness around the injured area
• Trouble standing, walking, or bearing weight
• A visible deformity, like the leg looking bent or shortened
• A snapping or cracking sound at the time of injury

Symptoms in children

• Crying or fussiness after a fall
• Refusing to walk or stand on the leg
• The child says the leg hurts when touched
• The child may have a fever if the bone is open or infected

Symptoms in older adults

• Pain and swelling may be less intense but still present
• The leg may look bruised or feel warm
• Difficulty moving the leg or getting up after a fall
• Sometimes confusion or agitation can be a sign of injury in older adults

Causes

Main causes

• Falls, such as slipping on ice or tripping on stairs
• Sports injuries from high-impact contact or twisting
• Motor vehicle or bicycle accidents
• Direct blows to the leg, like during a collision

Risk factors

• Weakened bones from osteoporosis or other bone conditions
• Older age and reduced balance
• Certain sports or activities with high risk of falling
• Poor nutrition that affects bone strength
• Smoking, which can slow bone healing

When to see a doctor

See a doctor urgently if:

• You think you may have broken your leg
• You are unable to put any weight on the leg
• You have severe pain, swelling, or bruising
• Your leg looks deformed or out of its normal shape

Book a routine appointment if:

• Pain, swelling, or trouble walking does not improve after a few days
• You had a minor injury but still feel discomfort after a week
• You need advice on how to safely return to activity

Diagnosis

A doctor will ask how you hurt your leg, examine it for swelling, tenderness, and movement, and usually order an X-ray to see if a bone is broken.

Tests that may be done

• X-ray – the most common test to see a break
• CT scan – may be used if the break is complex or around a joint
• MRI – may be used to check for damage to muscles, ligaments, or other soft tissues

What to expect at your appointment

You may be asked to change into a gown. The doctor will gently feel your leg and ask you to move it in certain ways. Then you will likely go to X-ray. If a break is found, a splint or cast may be applied before you go home.

Treatment

Treatment depends on the type and location of the break. Most broken legs are treated with a cast or brace to keep the bone still while it heals. Some breaks need surgery to line up the bone and hold it securely.

Self-care at home

• Rest the leg and keep weight off it until your doctor says it is safe
• Apply ice wrapped in a towel for 15–20 minutes several times a day
• Keep the leg raised on pillows to help reduce swelling
• Gently move your toes and ankle if your doctor allows it to help blood flow
• Follow your doctor's instructions about how much weight you can put on the leg

Medical treatments

Medical care may include a cast or removable brace to immobilize the leg. In some cases, traction or surgery is needed to align the bone. Surgery often involves metal rods, screws, or plates that hold the bone in place while it heals. After the cast or surgery, physical therapy helps you regain strength and movement.

When is surgery considered?

Surgery is usually needed if the bone is displaced (the ends are not lined up), the bone has broken through the skin, or the break is unstable and unlikely to heal correctly without support.

Living with this condition

Healing takes time, so plan to rest and adjust your daily routine. You will likely need crutches or a walker, and you may not be able to drive or work at first. Keep your leg elevated when sitting or lying down, and follow your doctor's advice about when you can put weight on it.

Lifestyle tips

• Keep your upper body active with gentle exercises like arm lifts or seated movements
• Use a shower chair or bench to make bathing safer
• Remove loose rugs and clutter to avoid falls
• Ask family, friends, or community services for help with shopping, cooking, and cleaning

Diet and exercise

Eat a balanced diet rich in calcium and vitamin D to support bone healing. While your leg heals, do gentle exercises recommended by your doctor or physical therapist. Do not return to sports or heavy activity until your doctor says you are ready.

Mental health and emotional wellbeing

Being less mobile can be frustrating and can affect your mood. It is normal to feel down at times. Talk to loved ones about how you feel, and remember that this difficult phase is temporary. If you feel very low, anxious, or hopeless, reach out to a mental health professional for support.

Prevention

Not all broken legs can be prevented, but you can reduce your risk. Regular exercise improves balance and strength. Wear proper footwear, use safety gear in sports, and make your home safer by clearing trip hazards and improving lighting.

Screening programmes

If you are older or have a bone-weakening condition, ask your doctor about bone density screening. A bone density test can help identify if you are at higher risk for fractures.

Complications

If left untreated

• The bone may heal in the wrong position, causing a deformity
• The bone may fail to heal completely (nonunion) or heal slowly
• There is a higher risk of infection, especially if the bone broke through the skin
• You may develop blood clots in the leg from immobility
• Long-term pain, stiffness, or disability could occur

Long-term outlook

With proper medical care, most broken legs heal well. The recovery process takes time, but physical therapy and patience can help you return to your normal activities. Most people regain good use of their leg and are able to do the things they love again.
