RESUMO
BACKGROUND AND AIM: Current leg prostheses in rotationplasty typically feature a thigh cuff, which, in cycling, may cause perspiration problems and friction-related abrasions of the skin. The aim has been to develop a socket-less prosthetic device for persons with a rotationplasty to be able to engage in high-intensity cycling without contracting abrasions. TECHNIQUE: The new device (Socket-Less Rotationplasty Prosthesis for Cycling) features a standard cycling shoe on the rotationplasty foot, replacing the conventional socket and thigh cuff. A reinforced 12-layer carbon fibre frame bolted to the aforementioned shoe, replacing the standard tube, connects to a prosthetic foot and a second cycling shoe. Alignment of the Socket-Less Rotationplasty Prosthesis for Cycling is done both statically and dynamically. DISCUSSION: The Socket-Less Rotationplasty Prosthesis for Cycling is lightweight and more ventilated relative to conventional sockets. All components can be replaced easily. Most important, however, is that the current user now can cycle 135 km on end without skin abrasions. CLINICAL RELEVANCE: The Socket-Less Rotationplasty Prosthesis for Cycling concept enables patients with a leg rotationplasty to engage in high-intensity cycling without contracting skin problems, thereby facilitating clients' participation.
