Improper use of a transtibial prosthesis silicone liner causing pressure ulceration.

We present the previously unreported hazard of creating pressure ulceration in a susceptible host by the improper use of a silicone prosthetic liner. An 80-yr-old man sustained a recent transtibial amputation for peripheral vascular disease. His comorbidities included vascular cognitive impairment, type 2 diabetes mellitus, coronary artery disease, anemia of chronic disease, postherpetic neuralgia, and pruritus of uncertain origin.
