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: 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 modular femoral prosthesis system for an orthopaedic hip implant and method of use is disclosed. The prosthesis system includes a femoral stem component and a plurality of collar components configured to be selectively coupled to the stem component in a fixed position adjacent to a neck of the stem component. Each of the collar components includes a base and is configured to secure an assembled femoral prosthesis to a patient's surgically prepared femur to provide stability for the assembled femoral prosthesis.

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.

The tool includes a first member operably associated with the first component and a second member operably associated with the second component. The second member includes a cap having a threaded recess and further includes a threaded rod adapted to engage the threaded recess so as to move the second member relative to the first member and the threaded rod is made of a harder metal than the threaded recess.

Abstract: An orthopedic surgical instrument and method for positioning an acetabular prosthetic component in a patient's surgically-prepared acetabulum is disclosed. The orthopedic surgical instrument has a base configured to engage the patient's pelvis, a first linkage pivotally coupled to the base, a locking mechanism operable to lock the first linkage in position relative to the base, and a second linkage removably coupled to the first linkage. The second linkage has an alignment axis corresponding to a desired abduction angle and a desired anteversion angle of the acetabular axis of the acetabular prosthetic component.

Abstract: An orthopaedic prosthesis for use in a hip replacement surgery. The orthopaedic prosthesis includes an elongated stem component that has a proximal body, a neck extending superiorly and medially from the proximal body and a tapered stem extending inferiorly from the proximal body. An anchor is positioned on the neck and is configured to be engaged by a surgical instrument. A system for use in assembling the orthopaedic prosthesis and a method of assembly are also disclosed.
