Abstract
A joint prosthesis and/or trial implant alignment system (10) for intraoperatively assisting an alignment of a joint prosthesis and/or trial implant (12) during a surgical procedure is disclosed. The system comprises patient-specific pre-operative data (14) forming a three-dimensional image (14) containing bone structure (32) and a predetermined alignment of the joint prosthesis and/or trial implant (12) thereon. A patient imaging device (16) is for producing patient-specific intraoperative data 18 which forms a two-dimensional image 18 showing bone structure (32) and a real-time position of the joint prosthesis and/or trial implant (12) thereon. Registration means (20) registers the intraoperative data 18 with the pre-operative data (14) based on geometry of said bone structure and/or geometry of said joint prosthesis and/or trial implant (12). A display device (22) for displaying an output of the registration means (20), thereby enabling a visual indication of the said real-time alignment of the joint prosthesis and/or trial implant (12) relative to the said predetermined alignment.
