A prosthetic foot with a structural component having a proximal attachment member for fastening the prosthetic foot to a below-knee tube, a below-knee shaft or a prosthetic knee joint, with a forefoot portion secured or formed on the structural component, and with a heel-side spring-damper system which is assigned to the structural component and which is compressed at a heel strike and bears on a sole-side guide element. The structural component is designed as a leaf spring which extends in a posterior direction from the proximal attachment means, and forms an arch and is guided in an anterior and distal direction, wherein the arch protrudes posteriorly beyond the guide element.

The invention relates to an orthopaedic aid, in particular to a prosthesis () or orthosis comprising an orthopaedic fluid damper () with a displacement chamber () formed in a housing (), with a piston () mounted in the displacement chamber (), with a fluid reservoir for a fluid (), with a return flow conduit () connecting the displacement chamber () to the fluid reservoir, with a valve () that can adopt an open position and a closed position, in which it at least partially closes the return flow conduit (), and with a joint () that has a first branch () and a second branch (), wherein the first branch () is connected to the housing () and the second branch () is connected to the piston (). A device () is also provided for detecting a joint force (FB) acting on the joint, which device () is designed to bring the valve () to the closed position when the joint force (FB) exceeds a predefined threshold value. The invention also relates to a method for control of the aid and a fluid damper () fitted therein.
