Abstract
INTRODUCTION
 The conventional use of a prosthetic device by amputees involves contact of the residual limb tissue with the prosthetic socket using an intermediate elastomer liner. Roll-on gel liners are applied directly to the limb, and slide into the rigid hard socket; the gels are generally silicone or plastic. Regardless of the material, or the liner system used on a residual limb, problems occur because of direct skin and socket or liner contact.1 The skin tissue of the residual limb is subject to compressive, shear, and tensile forces through weight bearing against the interface wall. In addition the skin is subject to heat/sweat issues that may be seasonal and related to the insulation properties of the interface material. A common problem encountered by the prosthetic user is socket odor, or odor emanating from socket liners.2 Proper hygiene does not guarantee the reduction of strong socket or liner odor over time. In addition, skin problems among amputees include rashes, blistering, mold/fungal infections and other skin irritations. The socket/wall interface (regardless of material composition) is subject to local skin sloughing, sweat, and skin oils in a warm/moist dark environment over hours of use providing an ideal environment for fungal and bacterial growth.3 To address this problem, our team evaluated a titanium and silicone hybrid cleaning and coating technology containing a silver fatty acid complex against the odor producing, Gram-negative, facultative anaerobe, Pseudomonas aeruginosa.4

Highlights
The conventional use of a prosthetic device by amputees involves contact of the residual limb tissue with the prosthetic socket using an intermediate elastomer liner
The plate was incubated for 48 hours at 37oC and the assay was recorded every 24 hours via photography to measure the zone of bacterial growth inhibition
No inhibition of bacteria was seen with uncoated liners against Pseudomonas aeruginosa in a Kirby Bauer assay
Summary
The conventional use of a prosthetic device by amputees involves contact of the residual limb tissue with the prosthetic socket using an intermediate elastomer liner. Regardless of the material, or the liner system used on a residual limb, problems occur because of direct skin and socket or liner contact[1]. The socket/wall interface (regardless of material composition) is subject to local skin sloughing, sweat, and skin oils in a warm/moist dark environment over hours of use providing an ideal environment for fungal and bacterial growth[3]. To address this problem, our team evaluated a titanium and silicone hybrid cleaning and coating technology containing a silver fatty acid complex against the odor producing, Gram-negative, facultative anaerobe, Pseudomonas aeruginosa[4]
