Plaster and cast

Plaster and Casts for the Safe Immobilization of Fractures and Injuries

Plaster and cast refer to the dressing materials used to immobilize fractures and other injuries that require complete or partial immobilization. These include both traditional plaster bandages made from natural plaster and synthetic cast dressings made from fiberglass fabric, supplemented by padding and other accessories for proper application.

This material is used in hospitals, medical practices, and by emergency medical services—anywhere where broken bones or ligament injuries require controlled immobilization for several weeks. The appropriate type for each individual case depends on the injury, the desired drying time, and the method of application.

Properties and Advantages of Plaster and Casting Materials

The product range covers various types of materials and application methods, from the classic plaster bandage to modern synthetic support casts. What they all have in common is the purpose of keeping an injured body part stable for the duration of healing.

Typical characteristics:

• Natural plaster and synthetic fiberglass versions available
• Available as a bandage, longette, or prefabricated splint, depending on the model
• Varying drying and application times depending on the version
• Padding material for use under rigid and supportive casts
• Manufactured without natural rubber latex
• Various widths for different body regions
• Can be worn for up to several weeks

The appropriate combination of material, shape, and width depends on the type of injury, the affected body region, and the preferences of the treating healthcare professional.

Which products are suitable for which applications?

Specialist E, white plaster, is suitable for traditional fracture treatment with natural plaster. According to the product specifications, the bandage features a perforated core, which allows for faster application and drying compared to non-perforated versions.

For injuries requiring particularly firm, long-lasting immobilization, Delta-Lite Plus, a synthetic support bandage, is suitable. According to the product information, the fiberglass bandage can be applied using standard examination gloves and is available in several colors in addition to white.

Delta-rol, a synthetic padding, is suitable for the necessary padding before applying a rigid or support cast. According to the product specifications, it is autoclavable and can therefore be used in settings where sterile conditions are required.

What should you look for when purchasing plaster and cast materials?

The choice of material is the primary consideration: natural plaster dries more slowly but is usually less expensive to purchase, while synthetic cast material offers greater strength with lower weight and is sometimes available in different colors.

The shape also plays a role—is a wrapped bandage needed for a circular dressing, a cut-to-size splint for partial immobilization, or a prefabricated splint for rapid first aid? In addition, the appropriate width depends on the affected body region.

Before applying a rigid or supportive cast, sufficient padding should also be used to prevent pressure sores. The selection and application are carried out by medical professionals, who determine the appropriate combination based on the specific injury.

Natural plaster or synthetic cast material—what’s the difference?

Natural plaster, in the form of plaster bandages and plaster splints, consists of a cotton backing with a natural plaster mixture. It is easy to mold and has long been established, but according to the product specifications, it takes up to 48 hours to reach full load-bearing capacity.

Synthetic material, available as cast bandages, cast splints, and cast braces, consists of fiberglass mesh coated with synthetic resin. It is lighter, more durable, and sometimes available in different colors, but is generally more expensive to purchase than natural plaster.

Both material lines are complemented by plaster shoes for safe walking while the cast is setting, padding to protect the skin, and other plaster and cast accessories. Neither material line is inherently better—the choice depends on the injury, the desired drying time, and the user’s preferences.

Application and Instructions for Plaster and Cast Materials

According to the product instructions, plaster bandages and cast materials are soaked in water at a temperature of 20 to 25 °C, then wrapped or cut to size and shaped as a longette. Depending on the type, the open time for shaping is a few minutes.

Proper application and monitoring are the responsibility of trained medical professionals. Any changes in the area of the dressing, such as pressure points or circulatory problems, should be reported immediately to the treating professional.

For storage of the material: Keep it dry and protected from moisture to ensure its properties are preserved until use.

Complementary Products for Plaster and Casts

• Compression and Support Bandages
• Cold therapy
• Instruments

Compression and support bandages offer a less rigid alternative when complete immobilization is not necessary. Cold therapy can be used to help reduce swelling, while items from the instruments category—such as bandage scissors—are needed for later removal of the bandage.
