Casts typically come in two main types of material, fiberglass, and plaster, though it is less common. Plaster casts have several limitations, including weight, which restricts movement, and skin complications such as dryness, itching, rashes, and infections, particularly in hot weather. Plaster can also break down if exposed to moisture.
Fiberglass casts were introduced in the 1980s or 1990s. The curing time of a fiberglass cast is far shorter than plaster of Paris, letting the patient walk with an outer boot within an hour of application. Because casts made of fiberglass have lower breakdown rate and do not impede patient mobility, this material has become the choice for TCC.
A controlled ankle motion walking boot, also referred to as a controlled ankle movement walking boot, below knee walking boot, CAM boot, CAM walker, or moon boot, is an orthopedic device prescribed for the treatment and stabilization of severe sprains, [3] fractures, and tendon or ligament tears in the ankle or foot.
When using plaster to cast a footprint, it is recommended to use a fixing agent to prevent the loss of detail when creating a plaster cast. These fixing agents include shellacs, glues, aerosol resins and hairsprays, which are sprayed liberally on the print before pouring the plaster of Paris into the impression. [5]
Plaster mold casting is a metalworking casting process similar to sand casting except the molding material is plaster of Paris instead of sand. Like sand casting, plaster mold casting is an expendable mold process, however it can only be used with non-ferrous materials. It is used for castings as small as 30 g (1 oz) to as large as 7–10 kg ...

Elektrische Gipssäge, a cast saw by Ortopedia (Kiel, Germany), is a power tool used to remove orthopedic casts which has an oscillating blade instead of a circular saw with a rotating blade This type of oscillating tool was originally developed by the German manufacturer Fein in 1967 [ 1 ] with a design intended to remove plaster casts easily ...
These casts were made by wrapping dipped plaster or fiberglass strips around the foot to capture the form, then letting it dry and harden. Once the cast was hardened, the doctor would carefully remove it from the patient's foot and ship it, along with a prescription, to an orthotics lab which would use the negative of the cast to create an ...
