Abstract
A method of making a custom acetabular implant for a patient. The method comprises acquiring and analyzing tomography data of the patient, and obtaining geometry and measurement parameters of the patient's pelvic anatomy. A standard acetabular prosthesis blank is selected from a plurality of pre-manufactured blanks, and includes a cup portion and at least one flange. The method includes shaping the blank acetabular prosthesis using a custom deforming fixture such that the shaped acetabular prosthesis has a final shaped geometry and measurement parameters to substantially match the patient's pelvic anatomy relative to the patient's acetabulum.

A method of making a custom acetabular implant for a patient, the method comprising:
- analyzing tomography data of the patient and obtaining geometry and measurement parameters of the patient's pelvic anatomy;
- selecting an acetabular prosthesis blank from a plurality of pre-manufactured acetabular prosthesis blanks, each acetabular prosthesis blank including a cup portion and at least one flange;
- shaping the acetabular prosthesis blank using a custom deforming fixture to form a custom acetabular prosthesis, wherein the custom acetabular prosthesis has a final shaped geometry and measurement parameters that substantially match the patient's pelvic anatomy relative to the patient's acetabulum.
A method of making a custom acetabular implant for a patient, the method comprising:
- analyzing acquired tomography data of the patient and obtaining geometry and measurement parameters of the patient's pelvic anatomy;
- obtaining a custom deforming fixture having dimensions modeled after the tomography data and matching the geometry and measurement parameters relative to the patient's acetabulum;
- selecting an acetabular prosthesis blank from a plurality of pre-manufactured acetabular prosthesis blanks that include a cup portion with at least one integral flange radially extending therefrom, the selected blank having measurement parameters substantially similar to the patient's pelvic anatomy;
- and
- customizing and shaping the acetabular prosthesis blank using the deforming fixture to shape the flange such that the shaped acetabular prosthesis will substantially mate with the patient's pelvic anatomy relative to the patient's acetabulum.
A method of making a custom acetabular implant for a patient, the method comprising:
- analyzing tomography data and obtaining geometry and measurement parameters of the patient's pelvic anatomy;
- determining a patient-specific configuration of the patient's pelvic anatomy relative to the patient's acetabulum;
- obtaining a custom press die mold having dimensions substantially matching the patient-specific configuration;
- selecting an acetabular prosthesis blank from a plurality of pre-manufactured monolithic acetabular prosthesis blanks including a cup portion and a plurality of integrally formed flanges radially extending therefrom, the selected blank having measurement parameters substantially similar to the patient's pelvic anatomy;
- and
- deforming the acetabular prosthesis blank using the custom press die mold and shaping at least one of the plurality of flanges to achieve the patient-specific configuration.
