What should you know about plaster of paris bricks?

People may use “brick” to describe a hardened block or piece of plaster material. That is different from the wet bandage layers used to make many orthopaedic casts. A clinician selects and prepares cast material according to the body part, the needed support, and the stage of treatment.

A rigid piece should not be placed against an injured limb at home. The shape, padding, edges, and fit all affect comfort and support. A cast also needs room for expected swelling and must allow the circulation and movement of exposed fingers or toes to be checked.

Do not try to repair, reshape, or attach a plaster brick to an existing cast. Keep the prescribed support dry and clean, protect it from knocks, and follow instructions about elevation, movement, and walking. If a cast feels loose, cracked, wet, or uncomfortable, contact the treating service for advice.

For general background on the material, see Plaster of Paris. Fracture Casting describes its clinical use when an injured bone needs support.

Get prompt medical advice for worsening pain, pressure, numbness, tingling, unusual colour or temperature in exposed digits, or an inability to move them. Urgent assessment is needed if the limb becomes markedly swollen, the cast causes a sore spot, or the support is damaged after an accident.

Ask what material and cast design you have, whether the support can bear weight, and how to check your fingers or toes. Clarify how to keep it dry, when it will be reviewed, and who to contact outside clinic hours.
