Abstract: A system for sizing an implant for a patient pre-operatively comprises a processor unit. A non-transitory computer-readable memory may be communicatively coupled to the processing unit and comprising computer-readable program instructions executable by the processing unit for obtaining at least one radiographic patient image of at least one patient bone with a scale marker relative to the bone, the scale marker having a known geometry, setting a scale of the at least one radiographic patient image using the known geometry of the scale marker, generating a three-dimensional bone model representative of the at least one patient bone using the at least one radiographic patient image and the scale, identifying an implant size and/or an implant model using implant models and dimensions of the three-dimensional bone model based on said scale, and outputting the implant size and/or the implant model for the patient.

Abstract: A pin placement instrument for placing a pin in a bone comprises an anatomical interface with a hook-like portion being opened in a lateral direction of the instrument to receive a bone therein in a planned position. A drill guide is connected to the anatomical interface and defining at least one guide slot in a longitudinal direction of the instrument. The guide slot has a lateral opening over its full length in the drill guide to allow lateral withdrawal of the instrument in said lateral direction with the pin placed in the bone passing through the lateral opening. A bushing is removably placed in said guide slot via said longitudinal direction in a planned fit, the bushing defining a throughbore aligned with the guide slot and adapted to receive the pin extending in said longitudinal direction when the bushing is in the guide slot for pin placement.

Abstract: A system for creating at least one model of a bone and implanted implant comprises a processing unit; and a non-transitory computer-readable memory communicatively coupled to the processing unit and comprising computer-readable program instructions executable by the processing unit for: obtaining at least one image of at least part of a bone and of an implanted implant on the bone, the at least one image being patient specific, obtaining a virtual model of the implanted implant using an identity of the implanted implant, overlaying the virtual model of the implanted implant on the at least one image to determine a relative orientation of the implanted implant relative to the bone in the at least one image, and generating and outputting a current bone and implant model using the at least one image, the virtual model of the implanted implant and the overlaying.
