Is my cast waterproof?
Are you suffering from a fracture and not sure whether your cast is waterproof? We see a lot of patients who need casts but not sure which one to get. This article will help you understand the types of fracture casts, their benefits, and drawbacks for your particular injury.
Types of Fracture Casts
Plaster of Paris
Plaster of Paris is the traditional casting material used for various fractures. It is white in colour, and powdery. It can be messy to apply and usually involves wetting the plaster in water before use. Plaster of Paris cast is often used following surgery or initially after an injury when swelling is present. Plaster of Paris casts are not waterproof and can soften easily when wet, so they must be kept dry at all times. Half casts are usually held in place with a bandage and can be removed easily. Full casts need to be removed with a plaster saw.
Synethetic Casting
Synthetic casting material is lighter than a normal plaster of paris cast, and will often last longer as it can withstand stress better. It is available in different colours and patterns along with options of what type of padding goes under a synthetic cast. Not all synthetic casts are waterproof. The waterproof part of a cast is mainly to do with the padding that is applied underneath the cast. Some synthetic casts have a cotton wrap or cotton wool type padding underneath – this is not waterproof! These casts need to be removed with a plaster saw.
Waterproof Casting
Waterproof casting is very popular for fractures, especially during summertime with increase in outdoor and water activities. Waterproof casting is a synthetic cast with waterproof padding underneath allowing patients to bathe, shower, and swim without compromising regular hygiene routines and injury healing process. The water will flow between your skin and the padding. Waterproof cast is quick drying and therefore there are no bad odors. It is lightweight and comes with a variety of bright or modern colors. Waterproof casts are a significant advancement in non-surgical fracture and injury care, offering patients greater comfort and convenience while maintaining efficacy and function.
Can I shower or swim with a waterproof cast?
Yes, you can shower, bathe, and swim (if approved by your doctor). Water drains out and the cast dries quickly. Swimming in clean water is generally permitted with waterproof casts and stable injuries. However, it’s essential to rinse the cast with clean water afterwards and allow it to dry completely. Swimming in dirty water or sea water is not allowed in most waterproof casts as sand can get trapped under the cast and cause skin damage.
Will a waterproof cast protect my skin?
Yes, the special liner helps prevent rashes, sores, and bad smells by letting your skin breathe. Regular casts can be unhygienic as they tend to stay wet and difficult to manage
How long does it take for a waterproof cast to dry?
Waterproof casts typically dry within 15-30 minutes after water exposure. Using a hair dryer on a cool setting can help speed up the drying process.
What precautions do I need to take when wearing a waterproof cast?
When used properly, waterproof casts don’t lose their structural integrity easily, however, excessive soaking should be avoided. In some cases, a waterproof cast may break down if the fracture is taking longer than usual to heal. In such cases, a patient may require one or more cast changes during treatment.
The following precautions are necessary to avoid fracture healing delays and complications:
1. Make regular inspections of skin around cast edges, and under the cast if possible
2. Avoid excessive exposure to water, and ensure proper drying after water exposure
3. Maintain good hygiene, and immediately report any unusual skin changes
4. Avoid excessive force or pressure on the cast or injury area
5. Use clean water only – avoid exposure to sand or soap
Is a waterproof cast comfortable compared to a regular plaster cast?
Yes, a waterproof cast is lighter, cooler, and causes less itching compared to regular casts.
Are waterproof casts suitable for all fractures? How to choose the right fracture cast for my injury?
No, waterproof casts are not suitable for all types of fractures. Unstable fractures that need reduction or realignment are usually better treated with Plaster of Paris or surgery, as it can be custom-molded. Choosing the right cast depends on the type, location, and stability of the fracture, as well as individual patient factors. It’s best to consult your doctor to make an informed decision.
Are waterproof casts more expensive than traditional casts?
Yes, waterproof casts generally cost more than traditional plaster casts. However, many patients find the additional cost worthwhile for the lighter weight, convenience, hygiene and increased function during treatment. Regular casts also need to be replaced if they get wet, which can add to the overall costs for patients.
How often can I shower with a waterproof cast?
Daily showering is permitted with waterproof casts. However, prolonged water exposure should be avoided. It is better to keep the cast dry with a protective outer plastic rather than frequently getting the cast wet, where soap and residue can get caught under the cast.
