A kit including a first component having a male taper and a second component having an internal bore with a female taper. The first component and second component being engageable via the male and female tapers. The kit further including a disassembly tool having a body and an expandable portion separable from the body, such that the expandable portion has an initial outer diameter equal to the inner diameter of the internal bore of the second component.

Taper disengagement tool

A disassembly tool for disassembly of a first component of a prosthesis from a second component of the prosthesis for use in joint arthroplasty. The tool includes a body having an internal bore. At least a portion of the internal bore is threaded for engagement with a thread on the first component of the prosthesis. The tool further includes an expandable ring surrounding a portion of the body and adapted to engage the first component, such that when a radial force is applied to the body, the ring expands, applying an axial force against the first component.

An assembly tool for assembly 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 operably associated with the first component and defines a first member longitudinal axis thereof. A second member is operably associated with the second component and defines a second member longitudinal axis thereof. A washer system is coupled to the second member. A drive mechanism is coupled to washer system, such that as the drive mechanism is activated, the washer system rotates about the second member longitudinal axis and expands along the second member longitudinal axis, wherein such movement further causes the second member to move relative to the first member along the second member longitudinal axis.

Spiral assembly tool

A method of assembling an orthopaedic implant includes positioning a first orthopaedic component in contact with a second orthopaedic component and coupling the first orthopaedic component to the second orthopaedic component with a bolt. The method also includes applying an empirically-determined starting torque to the bolt such that the first orthopaedic component is coupled to the second orthopaedic component with a first predetermined clamp load. The bolt is then rotated by an empirically-determined rotation angle such that the first orthopaedic component is coupled to the second orthopaedic component with a second predetermined clamp load.

Torque-turn orthopaedic bolt tightening method

An extraction device for removing a liner from an acetabular cup is provided. The extraction device includes a body and an actuator. The actuator is operably connected to the body. The extraction device also includes a jaw for cooperation with the liner. The jaw includes a portion of the jaw for penetrating into the liner. The jaw is operably connected to the actuator. The actuator is adapted to cooperate with the jaw to provide a first position for the jaw spaced from the liner and a second position for the jaw in contact with the liner.

Expandable acetabular liner extraction device, cup assembly and associated method

An extraction device for removing a liner from an acetabular cup is provided. The extraction device includes a jaw and a handle. The jaw is for cooperation with the liner and including a portion of the jaw for penetrating into the liner. The handle is operably associated with the jaw and is adapted for gripping the extraction device.
