A trial system for a prosthesis is described. The prosthesis can include an acetabular prosthesis generally for implantation in an acetabulum and the surrounding pelvis. The acetabular prosthesis includes an acetabular cup having a substantially concave inner surface and a substantially convex outer surface. One trial shell or a collection of trial shells are provided to trial a range of motion of the hip joint before implanting a shell prosthesis into the acetabular prosthesis.
1. An acetabular prosthesis system to replace at least a portion of an acetabulum of an anatomy, the system comprising: a trial cup configured to be removably positioned relative to a first portion of the anatomy;a trial cement mantle member configured to be removably positioned in a selected first
1. An acetabular prosthesis system to replace at least a portion of an acetabulum of an anatomy, the system comprising: a trial cup configured to be removably positioned relative to a first portion of the anatomy;a trial cement mantle member configured to be removably positioned in a selected first position relative to the positioned trial cup;a trial liner configured to be removably positioned at variable positions relative to the trial cement mantle member, the trial liner having an exterior convex surface, an interior concave surface opposite the exterior convex surface, a bottom edge defining a planar surface, and an elongated slot extending from the exterior convex surface to the interior concave surface, wherein the planar surface extends along a first reference plane, and wherein the elongated slot extends along a second reference plane generally perpendicular to the first reference plane; anda trial liner fixation member configured to removably secure the trial liner to the trial cement mantle member at each of the variable positions, the trial liner fixation member having a first portion extendable through the elongated slot of the trial liner,wherein the trial cement mantle member is positionable between the trial liner and the trial cup to replicate a cement mantle portion positionable between an implantable cup and an implantable liner,wherein the trial liner is configured to be positioned at variable positions relative to the trial cement mantle member, andwherein the enlongated slot facilitates a range of motion of the trial liner relative to the trial cement mantle member. 2. The system of claim 1, wherein: an implantable cup configured to be is implanted relative to the first portion of the anatomy after the positioned trial cement mantle member and the positioned trial cup are removed. 3. The system of claim 1, wherein the first portion of the trial liner fixation member is a shank, the trial liner fixation member having a head portion configured to bear against the trial liner to hold the trial liner at each of the variable positions. 4. An acetabular prosthesis system to replace at least a portion of an acetabulum of an anatomy, the system comprising: a trial cup configured to be removably positioned relative to a first portion of the anatomy;a trial liner configured to be removably positioned relative to the trial cup, the trial liner having an exterior convex surface, an interior concave surface opposite the exterior convex surface, a bottom edge defining a planar surface, a top-most portion defined at a position on the interior concave surface having a greatest distance from the planar surface, and an elongated slot extending from the exterior convex surface to the interior concave surface at the top-mosta trial cement mantle member configured to be removably positioned between the positioned trial cup and the trial liner to replicate a cement mantle portion between an implantable cup and an implantable liner; anda holding member configured to be received through the elongated slot and hold the trial liner in a selected first position or a selected second position relative to the trial cement mantle member, the selected first position different than the selected second position,wherein the trial liner is configured to be positioned at variable positions relative to the trial cement mantle member, andwherein the enlongated slot facilitates a range of motion of the trial liner relative to the trial cement mantle member. 5. The system of claim 4, further comprising: an implantable cup configured to be implanted in an acetabulum;an implantable liner configured to be cemented in the implanted implantable cup in a position substantially similar to the first position of the trial liner after removing the positioned trial cement mantle and the positioned trial cup. 6. The system of claim 4, wherein the trial cement mantle member includes a cooperation system including a indent on the trial cup and a projection on the trial cement mantle member; wherein the projection is configured to engage the indent. 7. The system of claim 4, further comprising: a protrusio cage positionable relative to the first portion of the anatomy;wherein the trial cup is configured to be positioned in the protrusio cage. 8. An acetabular prosthesis trialing system, the system comprising: a trial cup configured to be removably implantable in an acetabulum of a patient;a trial cement mantle member configured to be removably positioned relative to the implanted trial cup; anda trial liner configured to be removably positioned at a plurality of positions relative to the trial cement mantle member, the trial liner having an exterior convex surface, an interior concave surface opposite the exterior convex surface, and an elongated slot extending from the exterior convex surface to the interior concave surface; anda trial screw configured to be received through the elongated slot of the trial liner and fix the trial liner in a selected position relative to the implanted trial cup,wherein the trial cement mantle member is positionable between the trial liner and the trial cup to replicate a cement mantle portion positionable between an implantable cup and an implantable liner, andwherein the elongated slot defines an arc of at least 60 degrees to facilitate a range of motion of the trial liner relative to the trial cement mantle member. 9. The system of claim 8, wherein the arc of the elongated slot is between about 60 degrees and about 120 degrees.
