Orthopedic cast

life science Maturity 11-13 Next article →

An orthopedic cast is a very important medical tool. It helps the body heal after a break or a surgery. Doctors use casts to provide support to bones and soft tissues. This process is called immobilization, which means keeping an area still. By stopping movement, the cast helps bones and ligaments stay in the right place. This stability is necessary for proper healing to happen.

There are many different ways a cast can work. For arms, a long arm cast goes from the upper arm to the wrist. It keeps the elbow still, often at a 90-degree angle. A short arm cast only covers the wrist and part of the forearm. This allows the elbow to move more freely. Some special versions, called thumb spica casts, also keep the thumb still.

Leg casts are also very common for different injuries. A long leg cast goes from the upper thigh down to the toes. It keeps the knee joint from moving during healing. This cast often keeps the knee at a slight bend of 20 to 35 degrees. A short leg cast starts below the knee and goes to the toes. Some short leg casts have a toe plate to protect the toes from being hit.

Sometimes, a person needs extra help to move around. If they cannot put weight on a leg, they might use crutches. They might also use a walker or a wheelchair to stay safe. Some special walking casts have a hard, flat sole for balance. These help the person move while protecting the injury. Other people might use a knee scooter for more stability.

Keeping a cast clean and dry is a big job. Casts are often made of materials that do not breathe well. This can cause moisture to build up against the skin. Moisture can lead to bad smells or skin irritation. It is very important to keep the cast completely dry. If a cast gets wet, the material might become weak.
