Technique for guiding a surgeon on how to adapt a pre-planned position of at least one implant interface

A system comprising a processor configured to perform a method for guiding a surgeon on how to adapt a pre-planned position of at least one implant interface, wherein the at least one implant interface is configured to couple to an implant connector configured to connect the at least one implant interface with an implant interface of another implant, the processor configured to:

• obtain interface data indicative of a pre-planned position of at least one implant interface;
• obtain reference data indicative of one or more reference positions of the at least one implant interface, wherein the one or more reference positions are determined based on a regression analysis of a plurality of pre-planned positions of implant interfaces;
• determine, based on the interface data and the reference data, a deviation between the pre-planned position of the at least one implant interface and the one or more reference positions;
• and
• trigger display of a visualization comprising an indication of the deviation or of information derived from the deviation, to guide a surgeon on how to adapt the pre-planned position of the at least one implant interface.

A non-transitory computer-readable medium storing a computer program comprising instructions which, when executed on at least one processor, cause the at least one processor to:

• obtain interface data indicative of a pre-planned position of at least one implant interface;
• obtain reference data indicative of one or more reference positions of the at least one implant interface, wherein the one or more reference positions are determined based on a regression analysis of a plurality of pre-planned positions of implant interfaces;
• determine, based on the interface data and the reference data, a deviation between the pre-planned position of the at least one implant interface and the one or more reference positions;
• and
• trigger display of a visualization comprising an indication of the deviation or of information derived from the deviation, to guide a surgeon on how to adapt the pre-planned position of the at least one implant interface.
