Abstract

Abstract The joint ball (6) is provided with a conical clamping sleeve (3) for connecting to an adapter (4). The sleeve opens into a bowl-shaped cavity (7) surrounded by a rim (5). The endoprothesis comprises a sleeve (2) which is implantable into the upper region of a femur (8) beneath the trochanter major. An adapter in the form of a double-cone at the proximal end of the sleeve is used to receive the joint ball. An Independent claim is also included for a kit used to make the endoprothesis, comprising the implantable sleeve, the adapter and at least three joint balls containing bowl-shaped cavities with different depths (T).
