Mold for the forming of a spacer device for the replacement of an articular prosthesis

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

• a first half-shell providing a lower body comprising a first forming surface delimited by a first perimeter edge and configured to shape at least a first portion of the spacer device;
• and
• a second half-shell providing an upper body comprising a second forming surface delimited by a second perimeter edge and configured to shape at least a second portion of the spacer device,
• wherein the first half-shell and the second half-shell are configured to be removably coupled, in use, so as to define for the mold a closed configuration and delimit therebetween, at the first forming surface, the second forming surface, the first perimeter edge, and the second perimeter edge, a cavity corresponding to an external configuration of the spacer device,
• wherein the first perimeter edge is arranged to abut and come into contact, in use, with the second perimeter edge,
• wherein the mold comprises at least one channel adjacent to at least one of the first perimeter edge or the second perimeter edge, and/or to at least one of the first forming surface or the second forming surface,
• wherein the channel is configured to receive in use excess forming material for the spacer device, and
• wherein the first perimeter edge is continuous along all the first forming surface and the second perimeter edge is continuous along all the second forming surface.
