What should you know about plaster of paris what is it?

Plaster of Paris starts as a fine powder. When water is added, it becomes a paste and then hardens into a rigid material. In orthopaedics, a clinician applies layers over padding and moulds them around the body part. The result limits movement while a fracture, joint, or treated deformity is managed. It can also be used as an early cast because it is easy to mould while swelling is changing.

A medical cast is different from construction plaster: it is applied with protective technique and checked for pressure, fit, circulation, and skin problems. Learn more in [Plaster of Paris].

Follow the weight-bearing and movement instructions you were given. Keep the cast clean and dry, elevate the limb when advised, and move free fingers or toes gently if permitted. Do not trim the edges, loosen the layers, or place objects inside the cast. Keep follow-up appointments because the cast may need adjustment as swelling changes or healing progresses.

Plaster casting can be part of fracture care or a staged approach for clubfoot. Related explanations are available under [Fracture Casting] and [Clubfoot Casting].

Ask for prompt assessment if pain is worsening, the cast feels increasingly tight, fingers or toes become numb, cold, pale, or blue, or swelling remains severe. Contact the treating team for a cracked, wet, loose, or foul-smelling cast, or for rubbing, burning, discharge, or an open area at an edge. Sudden chest pain or breathlessness needs emergency care.

Ask what the cast is supporting, whether you may walk or use the limb, how to protect the skin and padding, and when it will be reviewed. Ask which changes in sensation, colour, swelling, or pain require same-day help.
