Radiographic features Plaster of Paris is radiopaque and when in place makes evaluation of fractures and bone positioning more difficult. It has very low signal on MRI. Ultrasound waves cannot pass through plaster of Paris and therefore it needs to be removed if ultrasound of the limb is needed.
Many joints will tolerate six weeks of immobility from casting. Ankle fractures and wrist fractures commonly immobilize the broken bone with a cast, and these joints get moving pretty quickly when out of plaster. Plaster of Paris is calcined gypsum roasted gypsum , ground to a fine powder by milling. When water is added, the more soluble form of calcium sulfate returns to the relatively insoluble form, and heat is produced. In addition, plaster is much smoother and does not snag clothing or abrade the skin.
Plaster of Paris is a building material that is used as a protective coating on walls and ceilings. Plaster of Paris is used to make sculptures and metal castings used as decorative in buildings.
Fiberglass has several advantages compared to plaster. It weighs less, so the cast made from it will be lighter. More durable and porous, fiberglass allows air to flow in and out.
Fiberglass is the better choice in case the limb must be X-rayed during the healing process. The muscles looks smaller.
The area is very smelly. All of this is normal and goes away within a few weeks. To help things go back to normal: Wash the skin with soap and water when you get home from getting the cast off. This will help it smell better! After that, wash the area with soap and water regularly, just like you wash the rest of your body.
If there are any scabs from the injury, do not pick at them. Picking can lead to infection. They will heal and go away on their own. Put a fragrance-free moisturizer on the skin after bathing to help with dry skin. Wait 3 days before shaving the area to give your skin time to heal.
Given time and the right care, the bone is able to heal itself. A plaster cast is applied to hold the arm or leg fracture in place while the bone heals.
Once the plaster has been applied, you are advised to see a doctor the next day to check that it is fitted correctly. On average, plaster casts stay on for about six weeks. This time is sometimes longer or shorter, depending on your age, general health and type of fracture. During this time, x-rays are done to check that the bone is healing well. If there are problems with the type of fracture or the way in which the fracture is healing, you may be referred to an orthopaedic surgeon bone doctor.
Pain and itchiness Common issues include: Fractures can be painful. The pain can be extreme at the beginning but it will ease when the plaster is on and the fractured limb is supported and rested. The pain will settle even further over the next few weeks.
Simple painkillers, such as paracetamol, are often needed. Check the packet for instructions. The plaster causes itchiness for a few days, but this should ease. Caring for the fracture The plaster cast supports and protects the fracture while the bone heals.
However, the cast can sometimes cause circulation problems. To help prevent this: In the case of an upper limb plaster cast, exercise the fingers often. In the case of a lower limb plaster cast, exercise the toes often.
Keep the plastered body part raised to prevent swelling, especially for the first 48 hours. For example, use a sling to keep an arm raised, or place pillows under your leg.
Ask the doctor or nurse for suggestions. Caring for the plaster The plaster is important, as it keeps the fracture in an acceptable position.
Suggestions include: Rest for a couple of days once the plaster is applied to allow it to set completely.
