General information

Casts are often used to treat non-displaced fractures or soft tissue injuries.

Splints and casts support and protect injured bones and soft tissues, reducing pain, swelling and muscle spasms. In some cases, splints and plaster casts are used after the operation.

These molds are customized and applied by your doctor or assistant. Molds are usually made of plaster of paris or fiberglass. Studs or half-casts can also be custom made, especially when an exact fit is required. In other cases, commercially available rails are used. These commercially available splints come in a variety of shapes and sizes, making them easier and quicker to apply. They feature Velcro straps to easily adjust the splint and make it easy to put on and take off. Unfortunately, a splint offers less support and protection than a cast and may not be a treatment option in all cases.

Fiberglass or plaster of paris material forms the hard backing layer in the splint and plaster of paris. Fiberglass is lighter, more durable and "breathes" better than plaster of paris. Both materials come in strips or rolls that are soaked in water and applied to a cotton or synthetic padding layer that covers the injured area.With fiberglass and plaster of paris splints and casts, a filler (usually cotton) is used as a protective layer next to the skin.

When using cotton pads, chemical fiber pads or plasters, the plaster must be kept dry. Serious problems can arise when these materials get wet. If the cast gets wet, it will soften and lose its strength and may no longer adequately support the injured area. Therefore, if the cast is not replaced, the fracture may heal in the wrong place. Cotton or synthetic upholstery may be difficult to dry when wet. This can cause the moist skin under the pad to develop a rash, become inflamed, or macerate. All of these disorders require additional treatment. In order to keep such patches dry, it is necessary to use commercially available plastic bath bags.

More recently, Gortex plaster interiors have been developed. The liner is fully waterproof, allowing the patient to fully submerge the cast without the protection of a plastic bag. With this type of cast pad coupled with the application of a fiberglass cast, the patient can engage in activities such as bathing and swimming without worrying about keeping the injured limb dry. However, in some clinical situations such plaster fillings cannot be used.

In order to ensure optimal support, the splint or cast must be precisely adapted to the shape of the injured arm or leg. Sometimes the cast needs to be replaced when the swelling goes down and the cast becomes "too big." Once the fracture has healed, the splint can often be reapplied to facilitate removal for treatment.

Cast care tips

In order for the treatment to be successful, you must carefully follow your doctor's instructions. The following information is for general guidance only and does not replace the advice of a doctor.

casting care

1. Swelling caused by the injury may put pressure on the splint or cast for the first 48 to 72 hours. This makes the injured arm or leg feel tight in the splint or cast. Reduce Swelling:

  • Raise the injured arm or leg over your heart and support it with a pillow or other support. If the splint or cast is on your leg, you will need to bend. The altitude allows clear fluid and blood to flow "downhill" to the heart.
  • Exercise your fingers or toes to reduce swelling, prevent stiffness, and increase blood flow.
  • Apply ice to the splint or cast. Place ice cubes in a dry plastic bag or ice pack and wrap loosely around the splint or pour over the injured area. Packing ice cubes in a hard container and only touching part of the mold is not effective.

2. If it is cotton or chemical fiber lining or plaster, please keep the plaster dry. Shower with a swim bag.

3. If you have a cast, you can shower or swim, but rinse it under running water afterwards.

4. File off any unevenness with sandpaper.

5. To relieve any itching symptoms, cool air can be blown into the plaster cast with a hair dryer.

6. Check blood flow by pressing on the nail bed. The nail should turn white when pressure is applied, but return to its normal color once pressure on the nail is released. If not, please contact your doctor.

7. Check the skin around the cast. Contact your doctor if the skin around the cast turns red or cracks.

8. Check the plaster regularly. If it breaks or develops soft spots, contact your doctor.

9. Keep dirt, sand and dust away from the inside of the plywood or plaster.

What not to do when caring for a cast

1. Unless you have a Gortex cast, do not wet the cast.

2. Do not insert objects such as hangers into the cast to relieve itching. Instead, use the cool setting of a hair dryer to blow air into the plaster.

3. Do not apply body powder or deodorant to itchy skin. If itching persists, contact your doctor.

4. Do not pull on the plasterboard. It protects your skin.

5. Do not break or trim the molding edges.

Warning sign after application of a splint/cast

After applying a splint or cast, it is important to elevate the injured arm or leg for 24 to 72 hours. The injured area should be higher than the heart. By resting and elevating the body, initial swelling is minimized, significantly reducing pain and speeding the healing process.If you experience any of the following warning signs, contact your doctor's office immediately.

  • Increased pain and swelling that cannot be controlled with ice, elevation, and/or painkillers.
  • The splint or cast feels too tight.
  • Numbness and tingling in the hands or feet.
  • Burn and burn.
  • Excessive swelling under the cast.
  • Loss of mobility in a toe or finger that needs urgent evaluation by your doctor.
  • There is a feeling of bubbles in the plaster.
  • Feel your calf swelling, tight and sore in the cast.
  • You notice unusual odors in the plaster.
  • If the plaster cracks or becomes too loose.
  • If the fused edges cause skin problems.
  • If you have a fever.

proper plaster removal

Never remove the patch yourself. You could injure your skin or prevent the wound from healing properly. Your doctor will remove the cast with a cast saw. Saw vibrates but does not rotate. When the saw blade touches the spacer in the plaster case, the spacer will vibrate with the saw blade.
