SkinSafe: Comparing Staphylococcus aureus Growth Across Liner Types in Kenya
The interface between an amputee鈥檚 residual limb and prosthetic liner is at risk for high levels of bacterial growth which can lead to infection. Silicone liners have the advantage of patient comfort, but they may have a sealing effect that could exacerbate bacterial growth, which is particularly a concern in places lacking clean water such as Kijabe, Kenya. To investigate this concern, the SkinSafe team has conducted a prosthetic liner study using a bacterial skin model which suspends a liner and a layer of agar above a self-regulating heat and water source to capture the dynamic behavior of the skin鈥搇iner interface. Staphylococcus aureus was grown on this model using three different liners: the Ossur Iceross silicone liner, the Namaste silicone liner, and the sock鈥揈VA liner. Final growth concentrations will be compared between the three liner types to determine whether silicone liners require additional hygiene protocols for use in Kenya.
