Broken Bones and Sprains: A&E or Urgent Treatment Centre?

The most common A&E dilemma

You have twisted your ankle, fallen on your wrist, or jammed a finger. It hurts, it is swelling, and you are not sure whether it is broken. Do you need A&E? Will a UTC do? Can you wait and see? This guide covers the clinical signs that distinguish fractures from sprains, the first aid that helps either way, and how to choose the right service.

Fracture vs sprain: what is the difference?

Fracture (broken bone)

A fracture is any break or crack in a bone. Fractures range from hairline cracks (stress fractures) that are hard to see even on X-ray to complete breaks where the bone is in two or more pieces. Compound fractures — where bone breaks through the skin — are the most serious and always require A&E.

Sprain

A sprain is damage to a ligament — the tough tissue that connects bones at a joint. Sprains are graded by severity:

• Grade 1 — mild stretching, minor swelling, the joint is stable
• Grade 2 — partial tear, moderate swelling and bruising, the joint is loosened
• Grade 3 — complete tear, significant swelling and bruising, the joint is unstable

A severe grade-3 sprain can be as debilitating as a fracture and may take longer to heal.

Strain

Often confused with sprains, strains involve damage to muscles or tendons (which connect muscles to bones) rather than ligaments. Treatment is similar to sprains.

How to tell them apart

The honest answer is that you often cannot tell without an X-ray. However, certain signs make a fracture more likely:

Signs suggesting fracture:

• Visible deformity — the limb looks bent, twisted or shortened compared to the other side
• Inability to bear any weight on the injured leg, or inability to grip anything with the injured hand
• A cracking or snapping sound at the time of injury (though sprains can also produce this)
• Pain that is very localised to one spot on the bone, especially if pressing directly on the bone produces sharp pain
• Rapid, severe swelling within the first hour
• Numbness or tingling below the injury, suggesting nerve involvement
• The skin looks pale or blue below the injury, suggesting blood supply compromise
• You are over 55 — bone density decreases with age, making fractures more likely from the same mechanism

Signs suggesting sprain:

• Swelling is around the joint rather than along the bone
• The joint moves (painfully) through its range of motion
• You can bear some weight, even if it hurts
• Bruising develops over hours rather than immediately
• The pain is worst when you move the joint, not when you press the bone

First aid: what to do immediately

Regardless of whether you suspect a fracture or sprain, the initial management is the same. Use PRICE:

• Protect — stop using the injured area. Do not try to test whether it is broken by moving it forcefully.
• Rest — sit or lie down, keep the injury still.
• Ice — apply an ice pack (or a bag of frozen peas wrapped in a tea towel) for 15–20 minutes every 2–3 hours. Do not apply ice directly to skin.
• Compression — if you have a bandage, wrap the area firmly but not so tightly that it restricts blood flow. If toes or fingers go numb, pale or tingly, loosen the bandage.
• Elevation — raise the injured area above the level of the heart if possible. For an ankle, lie down with your foot on cushions.

Take over-the-counter pain relief: paracetamol and ibuprofen can be taken together (assuming no allergies or contraindications). Ibuprofen also reduces inflammation.

Do not:

• Try to straighten a visibly deformed limb
• Remove shoes or boots from a swollen ankle — the swelling may make it impossible to get them back on, and the boot is providing compression and support
• Apply heat in the first 48 hours — this increases swelling
• Drink alcohol — it increases swelling and masks pain, which can lead to further injury

Choosing the right service

A&E is needed if:

• The limb is visibly deformed — bent at an abnormal angle, rotated, or shortened
• Bone is visible through the skin (compound fracture) — this is a medical emergency
• There is severe, uncontrolled pain that is not responding to over-the-counter painkillers
• The skin below the injury is pale, blue, numb or cold — this suggests blood supply compromise
• The injury involves the hip, pelvis, spine or skull
• The person is a young child and the mechanism was significant (fall from height, road traffic collision)
• The injury was caused by a high-energy mechanism (car crash, fall from height, crush injury)

Our guide on when to call 999 covers the circumstances where an ambulance is warranted.

A UTC can handle:

• Suspected simple fractures — wrist, ankle, finger, toe, forearm — where the limb looks roughly normal
• Sprains and strains
• Dislocated fingers or toes (though not shoulders or hips)
• Minor sports injuries
• Follow-up X-rays and cast adjustments (some UTCs offer this)

UTCs have X-ray facilities, can apply plaster casts and splints, and have clinicians experienced in musculoskeletal assessment. For a qualifying injury, a UTC is almost always faster than A&E. Our A&E vs UTC guide covers the full distinction.

Check live wait times to compare UTCs and A&E departments near you.

GP or self-care is sufficient if:

• You have a mild sprain with minimal swelling that is improving with PRICE
• You can bear weight and use the limb, though it is uncomfortable
• Bruising is developing slowly and there is no deformity
• Over-the-counter pain relief is controlling the pain adequately

If in doubt, call 111. The service has musculoskeletal pathways that assess whether you need imaging.

At the hospital

Whether you attend A&E or a UTC, the process for musculoskeletal injuries follows a similar pattern:

1. Registration and triage — as described in our A&E guide or the UTC equivalent
2. Clinical assessment — a clinician examines the injury, tests range of motion, and assesses nerve and blood supply below the injury
3. X-ray — if a fracture is suspected, you will be sent for imaging
4. Diagnosis — the clinician reviews the X-ray and tells you whether there is a fracture
5. Treatment — plaster cast, splint, sling, strapping, or advice on self-management depending on the injury
6. Follow-up plan — many fractures need a follow-up appointment at a fracture clinic within one to two weeks for review and possible re-imaging

Recovery

Fractures

Healing time varies by bone and severity. Wrist fractures typically take 6–8 weeks in plaster. Ankle fractures may take 6–12 weeks. During this time you may need follow-up at the fracture clinic, physiotherapy, and gradual return to activity. Your discharge paperwork should specify follow-up arrangements.

Sprains

Grade 1 sprains often recover within 2–3 weeks. Grade 2 can take 4–8 weeks. Grade 3 sprains may take several months and sometimes require surgery. Early physiotherapy improves outcomes for moderate and severe sprains.

For both injuries, our after discharge guide covers what to expect during recovery and when to seek further help.

Children and musculoskeletal injuries

Children's bones are still growing and have growth plates — areas of softer cartilage near the ends of bones. Injuries to growth plates need careful assessment because damage can affect future bone growth. Any child with a suspected fracture near a joint should be assessed at a service with paediatric expertise. Our children's A&E guide covers this further.

Complications to watch for

Most fractures and sprains heal without problems, but some complications are important to recognise early:

• Compartment syndrome — severe, increasing pain that is out of proportion to the injury, especially in a limb with a cast or tight bandage. The limb may feel tight, numb or tingly. This is a surgical emergency — attend A&E immediately if you suspect it.
• Deep vein thrombosis (DVT) — reduced mobility after a leg injury increases the risk of blood clots. Watch for calf swelling, warmth, redness or pain that worsens over days. Your discharge team should advise whether blood-thinning injections are needed.
• Infection in open wounds — if a fracture broke the skin, watch for increasing redness, swelling, warmth, discharge or fever in the days after treatment. Early antibiotics prevent serious bone infection.
• Malunion or non-union — bones that heal in the wrong position or fail to heal at all. Follow-up fracture clinic appointments exist to catch this early through repeat imaging.
• Chronic instability — severe sprains, particularly of the ankle, can leave the joint permanently looser if rehabilitation is incomplete. Physiotherapy and strengthening exercises reduce this risk significantly.

If you experience any of these warning signs, do not wait for a scheduled follow-up — attend A&E or contact your GP immediately.

Bottom line

If the limb looks deformed, bone is visible, or blood supply below the injury seems compromised, go to A&E. For everything else — suspected simple fractures, sprains, strains and minor musculoskeletal injuries — a UTC is faster and has the facilities to diagnose and treat you. Apply PRICE first aid immediately, take pain relief, and check live wait times to choose the least busy option near you.
