Normal pressure and pain sensations are essential for protecting the foot from excessive and prolonged pressures over bony prominences. In insensitive foot, such as in diabetic neuropathy, soft tissues are exposed to excessive pressures without knowledge of the individual.
Wheelchair users are at great risk for pressure sores. [1] A number of factors are included in the formation of these ulcers including: Insufficient vascularization in areas of high pressure, typically under bony prominences.

"The risk of excessive pressure on key bony prominences may cause injuries to the skin, and could result in minor joint sprains," he says. You can, however, carefully roll the sides of your knees ...
A venous ulcer tends to occur on the medial side of the leg, typically around the medial malleolus in the 'gaiter area' whereas arterial ulcer tends to occur on lateral side of the leg and over bony prominences. A venous ulcer is typically shallow with irregular sloping edges whereas an arterial ulcer can be deep and has a 'punched out' appearance.
A malleolus is the bony prominence on each side of the human ankle. Each leg is supported by two bones, the tibia on the inner side (medial) of the leg and the fibula on the outer side (lateral) of the leg. The medial malleolus is the prominence on the inner side of
The medial malleolus is the prominence on the inner side of the ankle, formed by the lower end of the tibia. The lateral malleolus is the prominence on the outer side of the ankle, formed by the lower end of the fibula. The trochanters are parts of the femur, to which muscles attach. [13] It may refer to the greater, lesser, or third trochanter
