Rigid immobilization refers to the process of holding a joint or bone in place with the use of a cast or splint. This is done to prevent an injured area from moving while it heals. The devices are firm (e.g., plaster, fiberglass) and not intended for self-removal.

Casts are generally used for the treatment of fractures, dislocations, and/or other musculoskeletal injuries. Splints are often used to immobilize a fractured or dislocated bone, or to maintain any part of the body in a fixed position.

Fracture care is the treatment of an open or closed fracture (broken bone) by performing a non-operative and/or operative technique. The non-operative technique is the treatment of a fracture typically with the use of a cast or splint and does not require surgery. While some bones can heal with the use of a cast or splint and do not require surgery, others may require a more invasive operative technique.

Walking aids are devices that are used to facilitate the physical movement of a person from one place to another in the event that they are unable to do so without assistance.
