ENDOPROSTHESIS WITH INSERTION JOINT AND IMPROVED ROTATIONAL PROTECTION Russian patent published in 2013 - IPC A61F2/28 

FIELD: medicine.

SUBSTANCE: invention refers to medicine. A prosthesis, particularly for at least a partial replacement of a long tubular bone comprises an insertion joint for connection of a pin with the other prosthesis part. The insertion joint is formed by an axial projection and a pocket. The pin comprises a transverse drill hole, while the other part accommodates a projecting non-pivotal rod wherein there is a lateral axis. The above lateral axis is engaged behind the projection and has a central axis which has an axial displacement (d) with respect to the axis of the transverse drill hole. A clamping element with its inserted end being engaged with the transverse drill hole is introduced into the lateral axis.

EFFECT: when using the insertion joint with the unitised prosthesis connection, the invention provides such holding of the insertion joint to enable the effort generation under all circumstances, including unfavourable intraoperative conditions, such as an inadequate approach to the operation site.
