Sprained wrist

A sprained wrist happens when a ligament (the tissue that connects bones at a joint) in your wrist is stretched or torn. Sprains and strains often happen during sports, exercise, sudden movements or falls.

Sprains are grouped into 3 grades based on how much the ligament is damaged.

Sprains are common in the ankle, wrist or knee. Other common wrist injuries include strains, fractures (broken bones) and dislocations.

Symptoms of a sprained wrist depend on the grade of your injury. They may include:

• swelling
• haematoma (a bad bruise)
• wrist pain and tenderness
• difficulty moving your wrist
• wrist instability
• weakness
• a 'pop' sound (which may suggest a grade 3 strain)

A sprain happens because of a sudden twist or wrenching motion. It is common in sports, exercise and sudden movements that involve:

• falling
• quickly changing direction
• repetitive strain

You are at higher risk of a sprained wrist if you:

• play sports — such as basketball, some types of football or contact sports
• have natural differences in your muscles or joints that make injuries more likely
• do exercises that put extra strain on your muscles

To diagnose a sprain, your doctor may:

• ask about your symptoms and how long you've had them
• ask if you know what caused the injury
• check you for pain, movement and wrist instability to see how serious your sprain is

To confirm the diagnosis and rule out other injuries, your doctor may suggest an:

• x-ray
• MRI scan
• ultrasound
• diagnostic arthroscopy — a procedure that uses a small camera inside your wrist to check for hidden damage

You should see your doctor if:

• you need advice on how to manage your sprained wrist
• your pain doesn't get better or gets worse over time
• your symptoms last more than a few days, as this may suggest a more serious injury

Treatment depends on how severe your sprain is. Most mild sprains can be treated at home. Moderate to severe sprains may need physiotherapy or medical treatment.

Self-care at home

Mild sprains can usually be treated with rest and care to help ease swelling and support healing.

Follow the RICE-GF for self-care at home:

• Rest — avoid activities that cause pain.
• Ice — apply an ice pack to bring down swelling (use a cloth to protect your skin).
• Compression — wrap your wrist with a bandage or brace to support it and bring down swelling. It should fit tightly against the skin, but not too tight, to avoid cutting off blood flow.
• Elevation — keep your wrist raised (above heart level if possible) to bring down swelling and pain. Rest your arm on a pillow when sitting.
• Gentle movement — depending on how much pain you have, start moving your wrist gently after 2 to 3 days.
• Follow-up — see your doctor after a week to make sure your wrist is healing properly. Your doctor will advise if you need further treatment.

Medicines

If you need pain-relief medicine, paracetamol and anti-inflammatory medicines (NSAIDs) may help.

Ask your doctor or pharmacist about the best pain-relief medicine for you, and the right dose for your circumstances. You may need to avoid certain medicines, especially if you have other health conditions.

Other treatment options

If you have a more severe sprain, your doctor may refer you to a physiotherapist. Physiotherapy can help improve movement and strengthen your wrist.

If the ligament is completely torn, your doctor may refer you to a surgeon for assessment.

You can lower your risk of a sprained wrist by keeping your wrist strong. Wrist exercises can help protect your wrist and keep it moving easily. This is especially important if you use your wrists a lot.

Strengthening your wrist muscles can also ease pain and help prevent long-term problems if you get injured.

Ask your doctor or physiotherapist for advice on the best wrist exercises for you.
