Preventing heel pressure sores: a comparison of heel pressure relieving devices.

It has been widely recognized that elderly patients with an orthopaedic problem are predisposed to developing heel pressure sores. In this study four pressure-reducing devices, commonly used in the prevention of heel ulcers, were objectively compared for their ability to decrease or remove pressure on the heels of patients with fractured necks of femurs and fractured femurs. Forty-one patients were randomly allocated a pressure relieving device. The efficacy of the device was evaluated by continuously assessing the skin integrity of both heels on a daily basis over a period of 12 days. Data were collected over a 30 month period. The four devices were foam splints, eggshell foam, duoderm and heel protector boots. Foam splints and eggshell foam proved to be more effective devices in relieving pressure exerted on the heel. This study recognizes that meticulous nursing care remains the critical element in prevention of heel ulcers; however, the use of eggshell foam and foam splints in conjuction with this enhances the maintenance of skin integrity.
