When we think about summer, we think about refreshing pool parties, exciting beach trips and long, warm evenings. These activities are all great fun but may bring some challenges to those who need to wear an orthosis.

Now that summer is in full swing, we like to share our top tips for keeping your patient’s orthosis summer-proof.


Dealing with Perspiration

Use a stockinette sleeve or a sock (with the toes cut off and a hole for the thumb) underneath the orthosis to absorb perspiration. Try socks made with moisture-wicking features to eliminate moisture.

Dealing with Water

Most thermoplastic orthoses can be worn while swimming, but need to be dried carefully afterwards. These are some additional swimming-related tips:

  • Use lightweight or breathable material, such as Orfilight or Orficast, if you know the patient is either very active or will go to the beach/pool.
  • Change the Velcro straps to dry ones so that nothing wet stays in contact with the skin.
  • If possible, have the patient take off the orthosis when swimming or bathing. Ask him or her to pat the area dry completely before putting the orthosis back on.
  • You can waterproof an orthosis by wrapping it in a couple of layers of plastic and sealing the edges with waterproof medical tape, or by using a waterproof product like a store-bought cast cover.
  • A blow dryer set to a cool (not warm or hot or the material might melt) setting can be used to help speed dry the material.

Dealing with Itching

If the patient is experiencing itching underneath the orthosis, advise him or her not to scratch or use any sharp objects to do this. It is better to use an anti-itch cream to alleviate the problem.

Ask your patient to let you know if the skin is irritated or raw. They might need additional padding and protection from the thermoplastic material.

Dealing with Smells

Use a fabric refresher to eliminate bad smells and restore a fresh feeling to the orthosis, especially those orthoses fabricated from Orficast and Orficast More products.

Use a disinfecting wipe to clean hard thermoplastic orthoses.

Dirty orthoses can be machine washed in a clothing bag on a mild programme at max 30°C/86°F. If possible, the velcro should be removed before doing this.

Dealing with Heat

Instruct the patient to apply sunscreen on areas that are not covered by the orthosis.

Thermoplastic materials are sensitive to heat and should be protected from temperatures above 65°C/149°F. That’s why an orthosis should never be left in the car or in the sun for a prolonged period of time, otherwise, the material could melt and lose its shape. Such as in the picture underneath:
