Dermatological problems of amputees due to excessive heat generation within the prosthetic socket can lead to ulcers, cysts, sores, infections, and tumors. Approximately two-thirds of those suffering from dermatological problems are lower limb amputees. Currently there is research into developing new prosthetic socket designs with lighter or ventilated material to alleviate these problems. However,...
This paper describes a microfeature scaffold that is being developed for tissue engineering. Typically, cells are grown on scaffolds that are designed to influence and direct their phenotype. By changing one or more properties of the scaffold, such as topography, it is possible to affect cellular phenotypes, including adhesion, orientation and function. In this work, the width of microscale patterns...
The development of pressure sores put patients at a high risk for developing infections and cause costly medical bills. It is important for wheelchair bound patients to constantly adjust positions in order to relieve pressure to decrease their chances of developing a pressure sore. The patient needs to adjust themselves at least every two hours in order to relieve the external pressure that is being...
The application of pressure to one area of skin for an extended period of time may lead to a loss in blood flow. This in turn may lead to the formation of a pressure sore. These could be life threatening and require very expensive negative pressure treatments in order to cure. Pressure sores are a large problem for paraplegics in wheelchairs since they are seated all day and cannot feel anything from...
