Femoral hip joint spacer with irrigation device

A femoral hip joint spacer for temporary replacement of a part of a hip joint, the hip joint spacer comprising:

• a prosthesis body having a ball head with a surface including both an irrigation liquid inlet opening and an irrigation liquid outlet opening, a neck with a proximal side connected to the ball head and a distal side which is opposite the ball head, a stem connected to the neck on the distal side of the neck and including both a proximal side and a distal side, and an anchoring sleeve connected to the stem including both a proximal side and a distal side and enclosing the stem on the proximal side of the stem with a circumferential fastening area, wherein
• the distal side of the stem includes at least one irrigation liquid discharge opening and either the ball head or the neck includes at least one irrigation liquid intake opening,
• the at least one irrigation liquid discharge opening is connected inside the prosthesis body in a liquid-permeable manner to the irrigation liquid inlet opening and is not connected inside the prosthesis body in a liquid-permeable manner to the irrigation liquid outlet opening, and
• the at least one irrigation liquid intake opening is connected inside the prosthesis body in a liquid-permeable manner to the irrigation liquid outlet opening and is not connected inside the prosthesis body in a liquid-permeable manner to the irrigation liquid inlet opening, and
• the anchoring sleeve includes a cavity formed inside the anchoring sleeve which is open on two sides, the cavity connecting the proximal side of the anchoring sleeve to the distal side of the anchoring sleeve in a liquid-permeable manner.
