Travelling with a cast or splint may seem challenging, but it doesn’t have to interfere with your plans. With the appropriate precautions and tailored adjustments, it is possible to fly safely and comfortably while your fracture heals.
Here’s what you need to know before boarding your flight with a cast or splint.
Why Flying Can Affect Your Injury
Changes in cabin pressure during air travel and being seated for extended periods of time can lead to increased swelling and reduced circulation in the arms and legs. For individuals wearing a cast or splint, this swelling can become uncomfortable and, in some cases, medically concerning if the device becomes too tight and affects circulation. There is also an increased risk of blood clots due to limited mobility during the flight, especially in those with recent injuries or surgeries. That’s why it’s important to prepare ahead of time and monitor your symptoms such as pain, numbness, tingling, or excessive swelling during the journey.
Flying with a Splint
One of the benefits of wearing a splint is its adjustability. At Hand Therapy Group, we use splints with Velcro straps, which can be loosened or tightened as needed to accommodate swelling.
Tips for flying with a splint:
- Loosen straps slightly during take-off and landing when swelling is more likely.
- Consider wearing compression socks underneath your splint to help manage swelling.
- Keep your arm elevated on a pillow or travel cushion when possible.
- Continue to monitor circulation. Check for signs including numbness, colour changes in your fingers, tingling, or increased pain.
Flying with a Cast
Casts are less flexible than splints, which is why we recommend bivalving the cast before you travel. Bivalving involves cutting the cast lengthwise in one or two places to create
room for swelling. The cast is then held together with strapping tape, which can be removed or adjusted if needed.
Before flying with a cast:
- Visit us a day or so before you travel to have your cast safely bivalved ahead of your trip.
- Take extra tape so you can ensure your cast is secure during your travels.
- Remember: a bivalved cast is still supportive, but it allows a bit more give if swelling occurs. Just make sure you keep the tape on.

Keep Moving!
Whether you’re in a cast or splint, gentle movement during the flight is essential to reduce swelling and improve circulation. Here are some ideas:
- Wiggle your fingers and thumb regularly.
- Gently bend and straighten your elbow (if it’s not immobilised).
- Roll your shoulders and move your neck to stay loose and relaxed.
- Elevate your arm above your head if needed for 10 – 15 minutes to help relieve symptoms.
Before You Fly
Make sure your splint or cast is comfortable and secure before your trip. Book an appointment with one of our friendly therapists at Hand Therapy Group for any adjustments or to bivalve your cast before you go.
And most importantly: Always consult your doctor or treating therapist before flying, especially if your injury is recent, involves surgery, or you have other health conditions that could affect your safety in the air.
