Abstract
This disclosure relates to orthopaedic implant systems and methods for restoring functionality to a bone and/or joint. The implant systems disclosed herein may include a taper connection between components. A hydraulic actuation device may be utilized to separate the components at the taper connection. A method of disassembling orthopaedic components is also disclosed.
Claims20
An orthopaedic implant system comprising:
- a head component associated with an articulation surface dimensioned to mate with an opposed articular surface of an adjacent implant or an adjacent bone;
- a mounting component including a mounting body, the mounting body including a fluid passage interconnecting a tapered recess and a mounting bore, the mounting bore extending from an engagement face and dimensioned to receive a fastener for securing the head component along the engagement face, the tapered recess extending along a first axis, and the mounting bore extending along a second axis transverse to the first axis;
- a second component including a tapered portion insertable in the tapered recess to establish a taper connection;
- and
- a hydraulic pump including an interface portion dimensioned to engage the mounting bore, wherein the pump is adapted to communicate fluid through the fluid passage to cause separation of the taper connection.
2 more elements
An orthopaedic implant system comprising:
- a first component including a female tapered portion and a mounting bore;
- a second component including a male tapered portion dimensioned to cooperate with the female tapered portion to establish a taper connection and a localized cavity;
- and
- a hydraulic pump adapted to communicate fluid through the mounting bore to cause separation of the taper connection in response to pressurizing the localized cavity.

An orthopaedic implant system comprising:
- a head component associated with an articulation surface dimensioned to mate with an opposed articular surface of an adjacent implant or an adjacent bone;
- a mounting component including a mounting body, the mounting body including a first tapered portion and a mounting bore, the mounting bore extending from an engagement face and dimensioned to receive a fastener for securing the head component along the engagement face, and the mounting bore transverse to the first tapered portion;
- a second component including a second tapered portion dimensioned to cooperate with the first tapered portion to establish a taper connection and a localized cavity;
- and
- a hydraulic pump adapted to communicate fluid through the mounting bore to cause separation of the taper connection in response to pressurizing the localized cavity.
2 more elements
An orthopaedic implant system comprising:
- a first component including a main body extending along a component axis between a first end and a second end, the main body including a first tapered portion and a coupling bore, wherein the first tapered portion extends from the first end, and the coupling bore extends inwardly from an outer periphery of the main body between the first and second ends;
- a second component including a second tapered portion dimensioned to cooperate with the first tapered portion to establish a taper connection and a localized cavity;
- and
- a hydraulic pump adapted to communicate fluid through the coupling bore to cause separation of the taper connection in response to pressurizing the localized cavity.
