The invention relates to a modular interim joint prosthesis that can be inserted into a long bone, for replacing an explanted joint endoprosthesis, wherein the interim joint prosthesis has a main body having a main-body coupling segment and has a shaft having a shaft coupling segment and the shaft coupling segment can be detachably coupled to the main-body coupling segment.

Interim joint prosthesis

A joint configuration is proposed for a joint endoprosthesis forming a hinge joint, comprising a joint receptacle, which has a joint receptacle surface and a receptacle locking structure, and a joint body, which is receivable in the joint receptacle and has a joint body surface and a body locking structure. The joint receptacle surface and the joint body surface are movable in relation to one another into a position in which the receptacle locking structure and the body locking structure assume a locked position, in which they can be engaged for a locked state between the joint receptacle and the joint body.

Joint configuration

Provided is a joint replacement with a joint socket () having a concave joint surface (), and with a joint insert () having a concave joint surface () and a convex joint surface () which are each delimited by a peripheral edge (). The convex joint surface () of the joint insert () is designed, in the assembled state, to form a first partial joint with the concave joint surface () of the joint socket (). Moreover, the concave joint surface () of the joint insert () is designed, in the assembled state, to form a second partial joint with the convex joint surface () of a joint head (). The joint socket () and the joint insert () each have a securing means () for preventing dislocation of the joint replacement.
