6. The prosthetic device of claim 5 , wherein said ilium member is configured to connect to a remaining portion of a healthy ilium of the first hemi-pelvis with at least one of bone screws, threaded fasteners and bone cement.

7. The prosthetic device of claim 5 , wherein said ilium member is configured to connect to a sacrum with at least one of bone screws, threaded fasteners and bone cement.

8. The prosthetic device of claim 1 , further comprising a plurality of anatomical connections points formed on at least one of said pubis member, an ilium member and an ischium member, wherein said plurality of anatomical connections points is operable to connect with a plurality of remaining bone portions and connective tissue from the first hemi-pelvis.

9. The prosthetic device of claim 1 , wherein the catch plate slides relative to the clamping portion and holds the pubis bone of the second hemi-pelvis between said catch plate and said clamping portion.

10. A prosthetic device for at least partial replacement of a first hemi-pelvis of a pelvis of a patient that defines a sagittal plane through the pelvis so a second hemi-pelvis is on a side of the sagittal plane opposite the first hemi-pelvis, the prosthetic device comprising:

an acetabular component operable to replace at least a portion of the first hemi-pelvis;

an ilium member attached to said acetabular component and operable to attach to remaining portions of a healthy ilium associated with the first hemi-pelvis; and

a pubis member connected to said acetabular component, said pubis member including a clamping portion and a catch plate that is moveable relative to the clamping portion, said clamping portion and said catch plate being operable to directly connect to an opposed pubis bone of the second hemi-pelvis on the side of the sagittal plane that is opposite said acetabular component by holding said opposed pubis bone between said catch plate and said clamping portion.

11. The prosthetic device of claim 10 , wherein said pubis member includes a worm drive that advances said catch plate toward said clamping portion to hold the opposed pubis bone of the second hemi-pelvis.

12. The prosthetic device of claim 10 , wherein said acetabular component is configured to connect to a prosthetic femoral head.

13. The prosthetic device of claim 10 , wherein said acetabular component is configured to connect to a natural femoral head.

14. The prosthetic device of claim 10 , further comprising an acetabular cup configured to connect to said acetabular component.

15. The prosthetic device of claim 10 , wherein the catch plate slides relative to the clamping portion and holds the pubis bone of the second hemi-pelvis between said catch plate and said clamping portion.

16. A method of replacing at least a portion of a first hemi-pelvis of a pelvis that defines a sagittal plane with a prosthetic device by connecting to a second hemi-pelvis that is on an opposite side of the sagittal plane from the first hemi-pelvis, of the method comprising:

imaging at least a first portion of the first hemi-pelvis of the pelvis;

constructing the prosthetic device based on said imaging of at least the first portion of the first hemi-pelvis;

resecting a second portion of the first hemi-pelvis such that connective tissues are still attached to a remainder of the first hemi-pelvis;

forming anatomical connection points on said prosthetic device to substantially match said remainder of the first hemi-pelvis;

implanting said prosthetic device that is operable to replace at least the portion of the first hemi-pelvis but not any portion of the second hemi-pelvis;

connecting a pubis member of said prosthetic device to an opposed pubis bone of the second hemi-pelvis on the opposite side of the sagittal plane from the first hemi-pelvis;

connecting said connection points on said prosthetic device to said remainder of the first hemi-pelvis on a side of the sagittal plane opposite the second hemi-pelvis.

17. A method of replacing at least a portion of a first hemi-pelvis of a pelvis with a prosthetic device comprising:

making an incision;

removing at least a portion of a first hemi-pelvis of the pelvis from the patient that defines a sagittal plane;

implanting the prosthetic device to replace at least the portion of the first hemi-pelvis but not a portion of a second hemi-pelvis;

connecting a pubis member of the prosthetic device to an opposed pubis bone of the second hemi-pelvis of the pelvis on a side of the sagittal plane opposite the first hemi-pelvis; and

rotating a worm drive to clamp said pubis member of the prosthetic device to said opposed pubis bone of the second hemi-pelvis.

18. The method of claim 17 further comprising securing an acetabular cup in an acetabular component operable to provide an acetabulum for the first hemi-pelvis.

19. The method of claim 18 further comprising connecting a prosthetic femoral head to said acetabular cup.

20. The method of claim 17 further comprising securing a connecting flange on the prosthetic device to the first hemi-pelvis of the pelvis with one of bone screws and bone cement.

21. A prosthetic device for replacement of at least a portion of a first hemi-pelvis of a pelvis defining a sagittal plane by connecting to a second hemi-pelvis of the pelvis on a side of the sagittal plane opposite the first hemi-pelvis, the prosthetic device comprising:

a pubis member connected to an acetabular component, said acetabular component operable to provide a replacement for an acetabulum of the first hemi-pelvis;

a clamping portion connected to said pubis member and configured to connect to an opposed pubis bone of the second hemi-pelvis on the side of the sagittal plane opposite the first hemi-pelvis; and

a catch plate opposite said clamping portion, said catch plate is operable to slide toward the clamping portion and hold the pubis bone of the second hemi-pelvis between said catch plate and said clamping portion to fixedly connect the prosthetic device that at least partially replaces the first hemi-pelvis to the second hemi-pelvis on the side of the sagittal plane opposite where the prosthetic device provides the replacement of the acetabulum of the first hemi-pelvis.
