3.5 Direct Effects of Pressure
Pressure will be exerted by a cast and its padding on a limb. The aim of the person who applies
the cast is to ensure that pressure is distributed evenly over as large an area as possible, and that
certain areas are well protected.
3.5.1 Even application of casts
Padding must be applied evenly with appropriate overlap so that there are no ridges

Care must be taken to ensure that the joints are correctly positioned before the application of
padding or it tends to wrinkle. Remember that wrinkles act as ridges when the casting material is
applied and will produce areas of high pressure.
