Orthopaedic taper assembly instrument for taper locking the components of a hip prosthesis during a hip replacement surgical procedure and method of using the same

A taper assembly instrument operable to taper lock orthopaedic components to one another, comprising:

• a proximal draw rod component comprising an elongated shaft having (i) a set of threads formed in its proximal end, and (ii) a tensile bar slot formed in its distal end,
• a distal draw rod component comprising an elongated shaft having (i) a set of threads formed in its distal end, and (ii) a tensile bar slot formed in its proximal end, wherein the proximal end of the elongated shaft of the distal draw rod component abuts the distal end of the elongated shaft of the proximal draw rod component such that (i) the elongated shafts of the proximal and distal draw rod components lie on a common longitudinal axis, and (ii) the tensile bar slots of the proximal and distal draw rod components open into one another,
• a sacrificial tensile bar component having a proximal end that is positioned in the tensile bar slot of the proximal draw rod component and a distal end positioned in the tensile bar slot of the distal draw rod component so as to couple the proximal and distal draw rod components to one another,
• a removable handle having a bore formed therethrough that extends from a proximal end of the handle to a distal end of the handle, wherein (i) the elongated shaft of the proximal draw rod component is received into the bore of the handle such that the threads formed in the proximal end thereof extend out of the proximal end of the handle, and (ii) the handle comprises an elongated outer surface that extends parallel to the handle’s bore and is configured to be gripped during use of the taper assembly instrument, and
• a knob threadingly engaged to the set of threads formed in the proximal end of the proximal draw rod component such that movement of the knob relative to the handle causes movement of the set of threads formed in the distal end of the distal draw component relative to the handle.
