Abstract
A spherical head endoprosthesis has a spherical head and a base piece. Between the base piece and the spherical head is a conical interference fit connection, wherein the spherical head has a conical bore and the base piece has a conical pin. The axis of the conical bore and the center line of the spherical head form an angle in the range of 7.degree. to 15.degree.. The conical bore is decentralized in relation to the center line with an offset of 1 to 4 mm. On the inside of the bore are at least five grooves parallel to the axis of the bore, into which, after assembly of the conical interference fit connection, grips at least one locking projection provided on the peripheral surface of the conical pin. The grooves may be designated by markings around the periphery of the bore opening for easy identification of the proper groove for insertion of the locking projection during the replacement operation.
