Mold with removable inserts for forming a spacer device for the replacement of a joint prosthesis

A mold for forming a spacer device for replacing a joint prosthesis, comprising:

• a first half-shell or lower body;
• and
• a second half-shell or upper body,
• wherein the first half-shell or lower body and the second half-shell or upper body are configured to be removably coupled, in use, so as to define a closed configuration of the mold, in which at least one of the first half-shell or lower body or the second half-shell or upper body comprises a seat for housing an insert,
• wherein the insert is interchangeable and configured to be housed in the seat,
• wherein the insert comprises a first forming surface and/or a second forming surface,
• wherein the first forming surface and the second forming surface define a cavity therebetween corresponding to an external configuration of the spacer device,
• wherein the seat has a conformation complementary and corresponding to a conformation of the insert, and the seat is a recessed seat in the first half-shell and/or in the second half-shell,
• wherein the first forming surface is delimited by a first perimeter edge and the second forming surface is delimited by a second perimeter edge, the first perimeter edge being configured to abut and come into contact, in use, with the second perimeter edge,
• wherein the first perimeter edge and the second perimeter edge respectively extend along an entire perimeter of the first forming surface and of the second forming surface,
• wherein the cavity is defined by coupling of first perimeter edge with the second perimeter edge, and
• wherein one or both of the first perimeter edge or the second perimeter edge are raised with respect to an upper face of the first half-shell or respectively a lower face of the second half-shell, so as to define an interspace between the upper face of the first half-shell and a lower face of the second half-shell.
