Abstract
A method of making an acetabular prosthesis includes acquiring a first set of data defining in three dimensions at least a portion of a bone of a patient. A second set of data is computed based upon the first set of data. The prosthesis is manufactured to include an acetabular cup and an attachment part extending therefrom. The manufacturing step includes the step of forming the attachment part based on the second set of data.
Claims31
A method of making an acetabular prosthesis comprising the steps of:
- acquiring a first set of data defining in three dimensions at least a portion of a bone of a patient;
- computing a second set of data based upon the first set of data;
- and
- manufacturing said prosthesis to include an acetabular cup and an attachment part extending therefrom configured to attach the acetabular cup to bone surrounding the acetabulum of a patient,
- wherein said manufacturing step includes the step of forming said attachment part based on the second set of data.
A method of making a prosthesis for a joint socket comprising the steps of:
- acquiring a first set of data defining in three dimensions at least a portion of a bone of a patient;
- computing a second set of data based upon the first set of data;
- and
- manufacturing said prosthesis to include a functional part and an attachment part extending therefrom configured to attach the functional part to the bone surrounding the joint socket,
- wherein said manufacturing step includes the step of forming said attachment part based on the second set of data.
A method of making an acetabular prosthesis comprising the steps of:
- acquiring a first set of data defining in three dimensions at least a portion of a bone of a patient;
- computing a second set of data based upon the first set of data;
- manufacturing said prosthesis to include an acetabular cup and an attachment part extending therefrom configured to attach the acetabular cup to bone surrounding the acetabulum of a patient, wherein said manufacturing step includes the steps of:
- forming said attachment part based on the second set of data,
- forming said attachment part to include a bone-facing surface and a tissue-facing surface, and
- forming said tissue-facing surface to be a partial facsimile of a surface of said bone.
An acetabular prosthesis, comprising:
- an acetabular cup;
- and
- a flange attached to said acetabular cup and configured to attach the acetabular cup to bone surrounding the acetabulum of a patient, said flange is prepared by a process including the steps of:
- acquiring a first set of data defining in three dimensions at least a portion of a bone of a patient;
- computing a second set of data based upon the first set of data;
- and
- manufacturing said flange based upon the second set of data.
A method of making an acetabular prosthesis comprising the steps of:
- acquiring a first set of data defining in three dimensions at least a portion of a bone of a patient;
- computing a second set of data based upon the first set of data;
- and
- manufacturing said prosthesis to include an integral component including an acetabular cup and an attachment part extending therefrom,
- wherein said manufacturing step includes the step of forming said attachment part based on the second set of data.
