Casts are typically removed by perforation using a cast saw, an oscillating saw designed to cut rigid material such as plaster or fiberglass while not harming soft tissue. [7] Manually operated shears, patented in 1950 by Neil McKay , [ 8 ] may be used on pediatric or other patients who may be affected by the noise of the saw.
The loss of a limb, or even death, was a possible outcome for a broken bone prior to the invention of the modern cast. Brilliant in its application, yet ingeniously simple, the cast method required little expense (bandages, plaster and water), minimal time for the physician, and provided a faster and more effective cure for broken bones.

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.
The family asked Kenny to care for their niece Maude, who was disabled by polio. After 18 months of care under Kenny's direction, Maude recovered sufficiently to walk, marry and conceive a child. [58] Kenny's use of hydrotherapy with Maude caught the attention of Mrs Herbert Brookes, wife of the Trade Commissioner-General for Australia. [59]
Antonius Mathijsen, a Dutch military surgeon, invented the plaster of Paris cast in 1851. Until the 1890s, though, orthopedics was still a study limited to the correction of deformity in children. One of the first surgical procedures developed was percutaneous tenotomy.
Elektrische Gipssäge, by Ortopedia, Kiel, Germany. A cast saw is an oscillating saw used to remove orthopedic casts.Instead of a rotating blade, cast saws use a sharp, small-toothed blade rapidly oscillating or vibrating back and forth over a minimal angle to cut material and are therefore not circular saws.

Plaster casts over fractures were sometimes called "Spanish dressings" In the Middle Ages an Italian a description appears in the thirteenth century, where surgical tape was recorded as sparadrappo , although there were some variations of spelling.
A long arm cast encases the arm from the hand to about 2 inches below the arm pit, leaving the fingers and thumbs free. A short arm cast, in contrast, stops just below the elbow. Both varieties may, depending on the injury and the doctor's decision, include one or more fingers or the thumb, in which case it is called a finger spica or thumb ...
