Cast saw

[2] The patient's skin frequently comes into contact with the cast saw blade without cutting although it can cause lacerations when used over bony prominences.

[3] The design enables the saw to cut rigid materials such as plaster or fiberglass.

In contrast, soft tissues such as skin move back and forth with the blade, dissipating the shear forces, and preventing injury.

These complications include skin abrasions or thermal injuries from friction between the saw and cast.

[4] Alternatives include cast cutting shears which were patented in 1950 by Neil McKay.
