Methods and systems for patient-specific acetabular implants

A system for customizing an acetabular shell to a bone of a specific patient, the system comprising:

• a provisional shell having a first surface and a second surface opposite the first surface, and a plurality of selectable openings extending from the first surface to the second surface;
• a provisional liner that corresponds to the provisional shell, wherein at least a portion of the provisional liner is transparent or semi-transparent, and wherein at least some of the plurality of selectable openings are viewable through the provisional liner when the provisional liner is placed adjacent the first surface;
• and
• an acetabular shell to be implanted in the bone, wherein the acetabular shell is configured to receive the provisional liner at the first surface, and wherein the provisional liner is configured to indicate a location for creating a hole in the acetabular shell.

A system for preparing a provisional liner, the system comprising:

• a processor coupled to memory including instructions for preparing the provisional liner, which when executed by the processor, cause the processor to:
• receive image data of a bone of a patient;
• render a three-dimensional (3D) model of the bone using the image data;
• output the 3D model of the bone for display on a user interface of a display;
• receive a user input via the a user interface of the display, the user input including a selected provisional shell;
• output a provisional shell 3D model corresponding to the selected provisional shell for display on the user interface of the display, the provisional shell 3D model including a plurality of selectable hole locations;
• receive a user input, via the user interface of the display, of a selected patient-matched hole location selected from the plurality of selectable hole locations;
• and
• generate a provisional liner 3D computer model including a guide opening corresponding to the selected patient-matched hole location.
