Abstract
A modular femoral prosthesis for use during performance of a hip revision procedure includes a proximal body component, a distal stem component, and a locking bolt. Surgical instruments and methods for use in implanting such a modular femoral prosthesis are disclosed.
Claims14
A distal reamer operable to ream an intramedullary canal of a patient's femur during a surgical procedure to implant a distal stem component of a modular orthopaedic hip prosthesis, comprising:
- an elongated shank having (i) a cutting head formed in a distal end of the elongated shank, the cutting head having a plurality of helical cutting flutes arranged in a geometry that corresponds with the geometry of the distal stem component, and (ii) a drive connector formed in a sidewall positioned at an opposite, proximal end of the elongated shank, the drive connector having (a) a female drive socket, and (b) a number of locking slots formed in the sidewall so as to open into the female drive socket.
A distal reamer operable to ream an intramedullary canal of a patient's femur during a surgical procedure to implant a distal stem component of a modular orthopaedic hip prosthesis, comprising:
- a cutting head having a plurality of helical cutting flutes arranged in a geometry that corresponds with the geometry of the distal stem component,
- a female drive socket, and
- a threaded bore having a superior end that opens into the drive socket and extending inferiorly away therefrom.
A surgical instrument assembly operable to ream an intramedullary canal of a patient's femur during a surgical procedure to implant a distal stem component of a modular orthopaedic hip prosthesis, comprising:
- a distal reamer having (i) a cutting head that includes a plurality of helical cutting flutes arranged in a geometry that corresponds with the geometry of the distal stem component, and (ii) a female drive socket, and
- an extension tool having (i) a connector configured to couple the extension tool to a rotary drive source, and (ii) a drive spline positioned in, and engaged with, the female drive socket of the distal reamer such that rotation of the extension tool causes rotation of the distal reamer.
