A modular acetabular cup assembly includes an acetabular cup, and a liner seated in the cup. The cup includes an end face, an apex opposite the end face, and a central axis extending between the apex and a center point of the end face. The liner includes an articular surface having a center of rotation which defines a pivot point of the acetabular cup assembly. In certain embodiments, the pivot point is laterally offset from the center point such that the end face is located between the pivot point and the apex.

Lateralized dual-mobility assembly

Prostheses, acetabular apparatuses, and methods of use are disclosed. In some embodiments, an acetabular apparatus includes an acetabular cup, a pre-assembled liner and flange construct, and a dual mobility bearing (e.g., a dual articulating femoral head component and insert). In one embodiment, the pre-assembled liner and flange construct may be coupled together by a band coupled to the flanges, the band being arranged and configured to be pressed onto an outer surface of a liner. The pre-assembled liner and flange construct being arranged and configured to accept the dual mobility bearing so that it is freely rotatable relative thereto during use.

Acetabular apparatus with dual mobility for hip revision surgery

A trial medical instrument for aligning an acetabular component, comprising: a first portion configured to fit within a patient's acetabulum; and a second portion extending from the first portion; wherein the second portion extends from the first portion in a direction that mimics a shape formed by a femoral implant component coupled with an acetabular implant component when a femur to which the femoral implant component is coupled is in a position relative to an acetabulum to which the acetabular implant component is coupled that is near an extent of a typical range of motion of the femur. As used herein, the phrase 'extent of a typical range of motion' describes typical angular displacements of a femur as usually limited by patient anatomy.

Acetabular implant alignment devices and methods

A surgical instrument handle assembly configured for rigid and releasable connection to orthopedic devices including orthopedic shaping or cutting members such as a broaches, reamers and/or osteotomes adapted to prepare the intramedullary canal of a femur in total hip arthroplasty procedures.

Surgical instrument handle assembly

Implants, surgical methods, and instrumentation for treating femoroacetabular impingement. In some embodiments, implants are provided or formed on the acetabulum to replicate the anatomy of the acetabulum (e.g., the acetabular rim and/or labrum, the bearing surface in the acetabulum, cartilage in the acetabulum, etc.). Also provided are embodiments of materials and instruments for use in installing and/or forming such implants on the acetabulum. Further provided are embodiments of guide jigs for use in preparing the acetabulum to receive such implants.
