Method for modeling a glenoid surface of a scapula, apparatus for implanting a glenoid component of a shoulder prosthesis, and method for producing such a component

A computer-implemented method comprising:

• obtaining imagery capturing a glenoid surface of a scapula of a patient;
• generating, based on the imagery, cartographic data representative of points belonging to the glenoid surface of the scapula;
• distinguishing from among the cartographic data a first group of cartographic data corresponding to a first part of the glenoid surface, the first part of the glenoid surface being situated farthest down in a vertical direction in relation to the scapula;
• generating, based at least on the first group of cartographic data, a spherical theoretical glenoid surface;
• and
• sending instructions to an output device to cause the output device to display a visualization of a glenoid component with an articular surface in line with the spherical theoretical glenoid surface.

A system, comprising:

• memory storing computer executable instructions;
• and
• one or more processors configured to:
• obtain imagery capturing a glenoid surface of a scapula of a patient;
• generate, based on the imagery, cartographic data representative of points belonging to the glenoid surface of the scapula;
• distinguish from among the cartographic data a first group of cartographic data corresponding to a first part of the glenoid surface, the first part of the glenoid surface being situated farthest down in a vertical direction in relation to the scapula;
• generate, based at least on the first group of cartographic data, a spherical theoretical glenoid surface;
• and
• send instructions to an output device to cause the output device to display a visualization of a glenoid component with an articular surface in line with the spherical theoretical glenoid surface.

A non-transitory computer-readable medium containing computer executable instructions that, when executed by one or more processors, cause the one or more processors to:

• obtain imagery capturing a glenoid surface of a scapula;
• generate, based on the imagery, cartographic data representative of points belonging to the glenoid surface of the scapula;
• distinguish from among the cartographic data a first group of cartographic data corresponding to a first part of the glenoid surface, the first part of the glenoid surface being situated farthest down in a vertical direction in relation to the scapula;
• generate, based at least on the first group of cartographic data, a spherical theoretical glenoid surface;
• and
• send instructions to an output device to cause the output device to display a visualization of a glenoid component with an articular surface in line with the spherical theoretical glenoid surface.
