Lower Limb Immobilisation and Blood Clot Prevention

When the lower leg is put into a splint, plaster cast or similar it can increase the risk of a blood clot, often called a deep vein thrombosis (DVT) or pulmonary embolism (PE). All patients who require immobilisation of their lower leg due to injury are required to undergo risk assessment for potential blood clots. If you have been assessed to be at increased risk of a blood clot during the time you require immobilisation you will receive medication to help prevent this. In addition to medications there are things you can do to reduce your risk of blood clots further and these are recommended for all patients irrespective risk.

What else can I do to reduce the risk of developing a blood clot?
It is difficult to predict who will get a blood clot, and whilst medication may help there are steps that can be taken to try and reduce this risk further:

  • Drink plenty of fluids.
  • Mobilise as much as is comfortable.
  • Stop smoking (if you smoke) – this will also help your bone to heal.
  • Perform the exercises described below (perform 3 times per day).

Exercises for reducing the risk of DVT in lower limb casts whilst you have to wear a cast, any activity which promotes contraction of muscles and increased blood flow is helpful.

For any cast on the legs
Wiggle your toes while lying in bed or whilst sat up with your leg elevated. Try and do this for at least 10 seconds, and as often as you can. This promotes blood flow and can help reduce the risk of blood clotting. Inside the plaster cast, if it is safe to do so, try and move your ankle up and down. It will not move very much as the cast will stop it. Repeat 10 times.

For below knee casts only
Regularly bend your knee. Sit down on a chair, bend your knee and then straighten your knee. Repeat ten times.

Lie on your tummy on the bed and bend your knee, bringing your heel towards your bottom. Slowly lower your foot back down to the bed, keeping the movement slow and controlled.

Lie on the bed or sitting up with your leg elevated. Keep your leg straight and brace your knee down by tightening the muscles on the front of your thigh.

How will I know if I have a DVT or PE?

When you have a DVT the blood flow in the vein is partially or completely blocked depending on the width of the clot. A calf vein is the common site for a DVT. A thigh vein is less commonly affected. Rarely, other deep veins in the body form clots.

The affected area of the blood clot may become swollen or painful, and possibly turn red or feel hot to touch as the flow of the blood is blocked. You may also develop swelling, which is the build-up of fluid in the skin tissues surrounding the clot. If the clot is somewhere other than in your leg, there may be no physical signs of DVT.

Sometimes bits of the clot can break up and lodge in the lungs causing a Pulmonary Embolism (PE) causing chest pain, difficulties with breathing, and coughing up blood streaked sputum. It may also cause sudden collapse.

Sometimes a DVT occurs for no apparent reason, and it becomes more common with age. Each year one in every 1,000 people in the UK is affected by DVT.

If you develop any of the signs or symptoms mentioned in this leaflet, please seek medical attention. Should you develop severe shortness of breath, chest pain or sudden collapse you or the person you are with should dial 999 for an ambulance, should you experience leg pain, swelling, redness, or warmth of your leg you should contact your GP or NHS111.

Where can I find out more?

Please ask your doctor or nurse for more information. Alternatively, the NHS Choices website provides patient information on blood clots: www.nhs.uk
