Abstract: A femoral prosthesis system for an orthopaedic hip implant and method of use is disclosed. The prosthesis system includes a femoral stem component that includes a core body and a casing that encases the core body. The casing can be additively manufactured such that the core body defines a predetermined orientation in the core body among a plurality of permissible predetermined orientations. The femoral stem component can further include a neck and a trunnion that extends from the neck. The neck can extend out with respect to the core body at a predetermined angle within a range of permissible predetermined angles.

Abstract: Kits and methods for use in intraoperative trialling of hip prostheses to determine an appropriate length for the femoral neck component of a prosthetic hip joint, are described. A kit for use in selecting a femoral neck component of an orthopaedic joint prosthesis kit comprises a first and a second broach. Each of the first and second broaches has a neck connection element comprising a projection extending from a proximal surface of the broach, each projection having a length.

Abstract: An orthopaedic system includes a femoral stem assembly having a protective casing or shell that protects one or more mating surfaces of the femoral stem component from incidental damage. The system includes a femoral head assembly having a protective casing or shell that protects one or more mating surfaces of the femoral head component from incidental damage. The system may also include a surgical instrument that is configured to detach or remove the protective casings from the prosthetic components of the femoral stem assembly and the femoral head assembly and secure the femoral stem component to the femoral head component. Methods of use and performing an orthopaedic surgical procedure are also disclosed.

Abstract: An orthopaedic surgical instrument system including a reamer assembly is disclosed. The reamer assembly includes a reamer head having a plurality of cutting teeth and a mounting bracket configured to be coupled to a femoral broach, which is sized to be positioned in a proximal opening of a femoral canal of a patient's femur. When the mounting bracket is coupled to the femoral broach, the reamer head is offset medially from the lateral edge of the femoral broach to resect a medial calcar of the patient femur.

Abstract: A disassembly tool for disassembly of a first component of a prosthesis to a second component of the prosthesis for use in joint arthroplasty. The tool includes a first member having a radial portion operably associated with the first component and adapted to exert a radial force on the first component. A second member operably associated with the second component is also included and the second member has a second member longitudinal axis. A drive mechanism is coupled to the second member, such that as the drive mechanism is activated, the second member exerts a force against the second component in the direction of the longitudinal axis. Such exertion of force against the second member further causes the second member to move relative to the first member along the second member longitudinal axis.
