Understanding Broken Arms

A broken arm, or arm fracture, is a common injury that can occur due to various reasons, including accidents, falls, and sports injuries. Understanding the anatomy of the arm and the different types of fractures can help in establishing an effective treatment plan.

Materials Needed

Step-by-Step Guide

Step 1: Prepare the Area

Ensure that you have a clean, sterile area to work in. Gather all materials and put on gloves to maintain hygiene.

Step 2: Assess the Injury

Before applying the cast, ensure that the injury has been assessed by a healthcare professional. Look for signs of swelling, bruising, or deformity.

Step 3: Apply Cast Padding

Wrap the arm in cast padding, covering all areas that will be in contact with the cast. Ensure that the padding is smooth and without wrinkles.

Step 4: Cut the Cast Material

Measure the length of the arm and cut the cast material accordingly. If using plaster, soak it in water until fully saturated.

Step 5: Apply the Cast

Wrap the cast material around the arm, ensuring even pressure and coverage. Overlap each layer by about half to ensure stability.

Once the cast is applied, use your hands to mold it to the shape of the arm. Ensure that the cast is not too tight, as this can cause circulation issues.

Once dried, check for any discomfort or tightness. Make any necessary adjustments to ensure comfort.
