Prevention of Skin Problems in Patients using Prosthetic Limb: A Review of Current Technologies and Limitations

Epidermis sore is one of the most iterative state affecting lower limb prosthetic users when the sockets do not align with the prosthesis. Skin that comes in contact with the prosthesis must be cared meticulously to prevent epidermis damage such as irritation, breakdown and infection. The proper solution for overcoming the before said problems is to design an ideal liner that will provide enough grip to limb so that it fits very well with the socket aligning according to the posture instantly, and it doesn't irritate the skin as it is designed in a way to support proper perspiration. The favorable and possible outcome of liner material is to deprive/eradicate the effects due to allergy, reducing the friction between the skin and socket and providing factual pressure distribution. This paper discusses the work related to appropriate selection of liner material which provides perfect cushioning, good adhesive properties, pressure distribution and good shear. The basic constituents used for socket material is natural fibre reinforced bio-composite material with the composition of glass and nylon fibre, which reduces epidermis sore and produces high tensile strength and young's modulus for the socket. The newly developed sockets were shown to provide a suitable friendly and ideal environment for the skins and subsequently improve the cushion properties. The expected conclusion is an ideal prosthetic liner with silicone as a major liner material and an ideal bio composite material for socket.
