Cast types used for a broken wrist

A splint is not closed all the way around the arm, so it can allow room for early swelling. A circumferential cast gives firmer support once swelling is controlled. Either may extend below the elbow or farther up the arm when rotation must also be limited.

Plaster moulds closely and is often useful when a newly aligned fracture needs careful shaping. Fibreglass is lighter and more durable, and is commonly used for a complete cast. The padding beneath either material protects the skin but can retain moisture.

Keep the cast clean and dry unless your team confirms that its complete cast system is water-safe. Do not push objects, powders or creams underneath. Raise the hand during early swelling and move the free fingers and thumb as instructed.

Check the cast edges and exposed skin each day. A cast should support the fracture without causing pressure injury or blocking circulation. Do not trim, reshape or remove it yourself; contact the clinic if it cracks, softens, becomes soaked or feels loose after swelling falls.

Seek prompt help if pain or tightness rapidly worsens, the fingers become pale, blue, cold, numb or difficult to move, or swelling does not improve with elevation. A bad smell, drainage, fever, burning pressure or a trapped object also needs assessment.

Do not wait for a routine appointment when the cast is cutting the skin or circulation seems impaired. Keep the arm raised while arranging care, but do not insert tools to create space.

Ask why this length and material suit your fracture, whether the wrist position has special importance, and how the alignment will be checked. Confirm bathing instructions, permitted finger use, activity limits and who to call if the fit changes.
