Abstract

See full text

An implant has two parts, each of which includes a joint surface facing the other part, wherein the joint surfaces are in contact with one another in an implanted state and permit pivoting of the two parts in relation to one another. An instrument for handling the implant includes a holding element for detachably connecting the instrument with each of the two parts of the implant. The instrument further includes a spacer element extending between the parts of the implant when the parts are connected with the instrument and maintaining a distance between the parts, thereby preventing the joint surfaces of the two parts of the implant from contacting each other.
