Pubic catch
First Claim
1. A prosthetic device for replacement of at least an acetabulum 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 the acetabulum of 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 operable to attach 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.

Abstract
A prosthetic device for replacement of a hip bone that includes an acetabular component configured to connect to a femoral implant and a pubis member. The pubis member connects to the acetabular component and includes a clamping portion that is configured to attach to an opposed healthy pubis bone. The pubis member further includes a worm or other clamping method drive that is configured to tighten the clamping portion against the opposed healthy pubis bone thereby providing stability to the prosthetic hip bone and avoiding the use of bone screws in the opposed healthy pubis bone.

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. - View Dependent Claims (11, 12, 13, 14, 15)

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. - View Dependent Claims (18, 19, 20)

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.
