Abstract
The invention relates to a joint prosthesis having an articular member fitted on an implant element housed in the bone cavity so as to slide without turning perpendicularly to the resection surface. The implant element is not provided with any abutting edge to limit its insertion into the bone cavity and the articular member is permanently supported with no twisting moment by the resection surface owing to its sliding possibility. The invention finds an application in hip joint endoprostheses.
