Spacer mould for producing a hip spacer, whereby the spacer mould comprises the following parts: a base element, in which a hollow mould is provided as negative image of one side of a femoral stem of the spacer to be generated, whereby a recess is arranged on the proximal end of the hollow mould in the base element and is connected to the hollow mould; a semi-spherical insert comprising a femoral head mould as negative image of one side of a femoral head of the spacer to be generated, whereby the semi-spherical insert is or can be arranged in the recess in the base element at a side of the recess that is opposite to the connection to the hollow mould, such that the femoral head mould is aligned in the direction towards the hollow mould; an adapter insert that is designed as a hollow body that is open on two sides and that is or can be arranged in the recess of the base element between the semi-spherical insert and the hollow mould such that the recess exerts a pressure onto the adapter insert and the semi-spherical insert, when the adapter insert and the semi-spherical insert are inserted into the recess, whereby the hollow body of the adapter insert connects the femoral head mould of the semi-spherical insert to the hollow mould in the base element; and a punch that comprises a punch hollow mould in the form of the negative image of the remaining femoral stem and that is arranged on or can be pressed onto the top side of the base element; whereby a cutting edge bounding the connection of the hollow mould of the base element to the punch hollow mould of the punch is arranged on the edge of the hollow mould of the base element and/or on the edge of the punch hollow mould of the punch, and a cutting edge bounding the connection of the femoral head mould to the opening of the hollow body of the adapter insert is arranged on the edge of the femoral head mould and/or on the edge of said opening of the hollow body of the adapter insert to the femoral head mould. a base element, in which a hollow mould is provided as negative image of one side of a femoral stem of the spacer to be generated, whereby a recess is arranged on the proximal end of the hollow mould in the base element and is connected to the hollow mould; a semi-spherical insert comprising a femoral head mould as negative image of one side of a femoral head of the spacer to be generated, whereby the semi-spherical insert is or can be arranged in the recess in the base element at a side of the recess that is opposite to the connection to the hollow mould, such that the femoral head mould is aligned in the direction towards the hollow mould; an adapter insert that is designed as a hollow body that is open on two sides and that is or can be arranged in the recess of the base element between the semi-spherical insert and the hollow mould such that the recess exerts a pressure onto the adapter insert and the semi-spherical insert, when the adapter insert and the semi-spherical insert are inserted into the recess, whereby the hollow body of the adapter insert connects the femoral head mould of the semi-spherical insert to the hollow mould in the base element; and a punch that comprises a punch hollow mould in the form of the negative image of the remaining femoral stem and that is arranged on or can be pressed onto the top side of the base element; whereby a cutting edge bounding the connection of the hollow mould of the base element to the punch hollow mould of the punch is arranged on the edge of the hollow mould of the base element and/or on the edge of the punch hollow mould of the punch, and a cutting edge bounding the connection of the femoral head mould to the opening of the hollow body of the adapter insert is arranged on the edge of the femoral head mould and/or on the edge of said opening of the hollow body of the adapter insert to the femoral head mould.
