Abstract
An orthopaedic surgical system for use in a direct anterior approach orthopaedic surgical hip replacement procedure on a patient's femur includes a proximal guide instrument for guiding a flexible insertion instrument to install a cement restrictor component. A method of installing a cement restrictor component during performance of a direct anterior approach orthopaedic surgical hip replacement procedure is also disclosed.
Claims18
A method of installing a cement restrictor component during performance of a direct anterior approach orthopaedic surgical hip replacement procedure on a patient's femur, comprising:
- sliding an elongated shaft of an insertion instrument through an elongated bore of a proximal guide instrument, the insertion instrument having a handle on its proximal end and the proximal guide instrument having an elongated post through which the bore extends and a neck extending medially from the elongated post,
- securing the cement restrictor component onto a distal end of the insertion instrument so as to slidably capture the proximal guide instrument on the elongated shaft between the handle of the insertion instrument and the cement restrictor component,
- advancing the cement restrictor component through a surgically-prepared proximal end of the patient's femur and into an intramedullary canal of the patient's femur,
- sliding the proximal guide instrument along the shaft of the insertion instrument such that the post and the neck of the proximal guide instrument are frictionally secured in the surgically-prepared proximal end of the patient's femur, and
- sliding the shaft of the insertion instrument relative to the secured proximal guide instrument such that the cement restrictor component is advanced distally into the intramedullary canal of the patient's femur to a desired depth.
A method of installing a cement restrictor implant component during performance of a direct anterior approach orthopaedic surgical hip replacement procedure on a patient's femur, comprising:
- sliding an elongated shaft of an insertion instrument through an elongated bore of a proximal guide instrument, the insertion instrument having a handle on its proximal end and the proximal guide instrument having an elongated post through which the bore extends and a neck extending medially from the elongated post,
- securing the cement restrictor implant component onto a distal end of the insertion instrument so as to slidably capture the proximal guide instrument on the elongated shaft between the handle of the insertion instrument and the cement restrictor implant component,
- advancing the cement restrictor implant component through a surgically-prepared proximal end of the patient's femur and into an intramedullary canal of the patient's femur,
- sliding the proximal guide instrument along the shaft of the insertion instrument such that the post and the neck of the proximal guide instrument are frictionally secured in the surgically-prepared proximal end of the patient's femur,
- sliding the shaft of the insertion instrument relative to the secured proximal guide instrument such that the cement restrictor implant component is advanced distally into the intramedullary canal of the patient's femur to a desired depth, and
- unsecuring the cement restrictor implant component from the distal end of the insertion instrument once the cement restrictor implant component has been advanced to the desired depth so as to implant the cement restrictor implant component at the desired depth.
An orthopaedic surgical system for use in a direct anterior approach orthopaedic surgical hip replacement procedure on a patient's femur, comprising:
- a proximal guide instrument having (i) an elongated post having a bore formed therein, the bore extending from a superior end of the elongated post to an inferior end of the elongated post and having a common diameter throughout its entire length, and (ii) a neck extending medially from the elongated post,
- an insertion instrument having (i) a handle at its proximal end, (ii) a threaded distal end, and (iii) a flexible elongated shaft extending distally away from the handle to the threaded distal end, the flexible elongated shaft having a diameter that is sized to be slidingly received in the bore of the proximal guide instrument, and
- a cement restrictor component configured to be threaded onto the threaded distal end of the insertion instrument.
