Abstract
An implantable joint prosthesis, e.g. to restore a joint between a distal bone and a proximal bone (for example a finger joint or toe joint) consists of a one-piece body of a material which is flexible and elastic (resilient) and has tapering projections extending in opposite directions from a central portion and adapted to be fitted into the respective bones. The central portion is formed at an intermediate location with a relatively thin region defining the articulation axis and with a pair of bulges which project in all directions transverse to the axis of the body outwardly of the respective projections on either side of this region and between the articulation region and the respective projection. The rounded bulge at the proximal side of the device is larger in volume than the rounded bulge at the distal side.
