Causes
Pressure
The areas at greatest risk are where there are weight-bearing bones near the surface of the skin, i.e. under the bones in the buttocks (ischeal tuberosities). People with normal muscle tone instinctively move when pressure builds up because they experience discomfort. People with limited physical abilities, may be unable to do this consciously
Temperature and humidity
If an area of skin becomes too hot, the cells need more oxygen to produce energy. In areas where blood flow is already restricted, this may not be possible. On the other hand, if the area is too cold, then the cells will produce less energy. In both cases the cells are not able to function properly and are prone to damage.
Continence difficulties
An inability to control the bladder and/or bowel will increase the 'dampness' of the buttock and thigh area making the skin more prone to damage. In addition, urine and faeces contain substances that further increase the likelihood of the skin breaking down.
Neurological dysfunction
People with a spinal injury, may suffer complete or partial loss of sensation in various parts of the body. People with these problems may not feel discomfort as pressure builds up.
