Overview
A limb X-ray is a quick and painless imaging test that uses a small amount of radiation to take pictures of the bones in your arm, leg, hand, or foot. It helps doctors see fractures (breaks), dislocations, infections, or other bone problems.
Key facts
Limb X-rays use a very low dose of radiation, similar to what you get from a few days of natural background radiation.
The test takes only a few minutes and is usually done in a hospital radiology department or clinic.
You will be asked to remove any jewellery or metal objects from the limb being X-rayed, as they can block the image.
No special preparation is needed – you can eat, drink, and take your regular medicines as usual.
Questions about this article
Yes, limb X-rays are one of the most common medical imaging tests performed worldwide. They are used frequently in emergency departments, GP surgeries, and orthopaedic clinics.
Limb X-rays can be done for people of all ages, from young children to older adults. They are most often done when someone has an injury, such as a fall or accident, that may have broken a bone.
Symptoms
Call emergency services immediately if you notice:
A bone is sticking out through the skin (open fracture) – call your local emergency number immediately
The limb is bent at an unnatural angle or looks severely deformed
The foot or hand is cold, blue, or numb after an injury – this could mean a serious blood flow problem
See a doctor urgently (same day) if you notice:
⚠You cannot move the limb at all after an injury
⚠You have severe pain that does not get better with rest or simple pain relief
⚠You have a known fracture and the pain suddenly gets much worse, or your fingers or toes become tingly or weak
Common symptoms
Pain in the arm, leg, hand, or foot after an injury
Swelling or bruising around the injured area
Difficulty moving the limb normally
Visible deformity or unusual angle of the limb
Symptoms in children
Refusing to use the arm or leg (favouriting the other side)
Crying or showing distress when the limb is moved
Swelling that appears quickly after a fall or bump
Symptoms in older adults
Sudden pain in a limb after a minor fall or even a simple twist
Inability to bear weight on a leg or stand up
Bruising that seems worse than expected for the injury
Causes
Main causes
Limb X-rays are used to check for broken bones (fractures) after an injury such as a fall, sports accident, or car crash
They can help diagnose bone infections (osteomyelitis), arthritis, or bone tumours
They are sometimes used to see if a bone is healing properly after a fracture
Risk factors
Having a condition that weakens bones, such as osteoporosis or certain cancers
Playing contact sports or having a job with a high risk of falls or heavy lifting
Being older – bones become more fragile with age
Taking certain medicines long-term, like steroids, which can weaken bones (but your doctor will discuss this if relevant)
When to see a doctor
See a doctor urgently if:
Go to an emergency department if you have an open fracture (bone through skin), severe deformity, or a limb that feels cold or numb
See a doctor or go to urgent care if you cannot put any weight on the leg or use the arm after a fall
Book a routine appointment if:
Make an appointment with your GP or a sports medicine doctor if you have persistent pain or swelling in a limb that started after a minor injury and is not getting better within a few days
Most limb X-rays are done to rule out a broken bone, and many injuries turn out to be sprains or strains that heal on their own. If you are unsure, it is always better to get checked.
Diagnosis
A limb X-ray is usually the first test when a bone injury is suspected. The doctor or radiographer (the specialist who takes X-rays) will position the limb carefully and take one or more images from different angles. The pictures are then reviewed by a radiologist (a doctor trained to read X-rays) who sends a report to your own doctor.
Tests that may be done
Limb X-ray (plain X-ray)
Sometimes a CT scan or MRI may be needed if the X-ray is not clear or if soft tissues (like ligaments) need to be checked
What to expect at your appointment
You will be asked to remove any jewellery or metal objects from the limb being X-rayed. You will stand, sit, or lie down, and the radiographer will position your limb on the X-ray machine. They may ask you to hold still for a few seconds while the picture is taken. You will feel nothing – just the slight pressure of the board or surface. The whole process usually takes about 10–20 minutes.
Treatment
Treatment depends on what the X-ray shows. If there is a fracture, the bone may need to be put back into position (reduction) and held still with a cast or splint. For simple fractures, a cast or splint is often enough. For more complex breaks, surgery may be needed to fix the bone with metal plates, screws, or rods.
Self-care at home
Rest the injured limb and avoid putting weight on it until you know the extent of the injury
Apply ice wrapped in a cloth for 15–20 minutes every hour to reduce swelling
Keep the limb elevated (raised) on pillows to help swelling go down
Take over-the-counter pain relief like paracetamol or ibuprofen (ask your pharmacist which is right for you)
Medical treatments
If a fracture is found, the doctor may apply a plaster cast or a removable splint to hold the bone in place while it heals. Pain relief may be prescribed. In some cases, the fracture needs to be ‘set’ (reduced) under sedation or anaesthesia. After the initial treatment, follow-up X-rays may be done to check that the bone is healing correctly.
When is surgery considered?
Surgery may be needed if the fracture is severe, the bone is broken into many pieces, the bone has broken through the skin, or if the bone is not healing after several weeks in a cast. Your orthopaedic surgeon will explain which type of surgery is best for you.
Living with this condition
If you have a fracture, you will need to adapt daily activities while the bone heals. For a leg fracture, you may need crutches or a walker. For an arm fracture, you may need help with tasks like dressing or eating. Most fractures heal within 6–8 weeks, but some take longer.
Lifestyle tips
Follow your doctor's advice about weight-bearing – some fractures require you to avoid putting any weight on the leg until it heals
Keep the cast or splint dry – cover it with a plastic bag when showering
Attend all follow-up appointments and X-rays to monitor healing
Diet and exercise
Eat a balanced diet rich in calcium (milk, yoghurt, leafy greens) and vitamin D (sunlight, fortified foods) to help bones heal. Gentle exercise of the unaffected limbs, as advised by your doctor or physiotherapist, can keep muscles strong. Avoid high-impact activities until the bone is fully healed.
Mental health and emotional wellbeing
Recovery from a fracture can be frustrating, especially if you are unable to work or do your usual activities. It is normal to feel upset or anxious. Talk to your doctor or a counsellor if you feel very down. Stay connected with friends and family for support.
Prevention
Many limb fractures can be prevented by taking sensible precautions. Falls are the most common cause, so making your home safer (remove rugs, improve lighting) and wearing appropriate footwear can help. For older adults, exercises that improve balance and strength reduce the risk of falls.
Screening programmes
If you have osteoporosis (weak bones), your doctor may recommend bone density scans every few years to monitor your bone health. This is not a regular screening for everyone, but it may be advised for postmenopausal women or those with certain risk factors.
Complications
If left untreated
A broken bone that is not properly treated may heal in the wrong position, causing permanent deformity or difficulty using the limb
An untreated fracture can lead to chronic pain or arthritis in the nearby joint
In rare cases, a bone infection (osteomyelitis) can develop if the skin was broken
Long-term outlook
The outlook for most limb fractures is excellent. With proper treatment, the vast majority of bones heal well and you can return to your normal activities. Some complex fractures may take longer, but with patience and rehabilitation, good function is usually regained.
