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.
Claims18
A surgical instrument for use during a surgical procedure to implant an orthopaedic hip prosthesis, comprising:
- a finishing rasp comprising (i) an elongated shaft having a bore formed therein, the bore having an open end defined in a distal end of the elongated shaft and a blind end positioned proximally of the open end within the elongated shaft, (ii) a handle secured to an opposite, proximal end of the elongated shaft, and (iii) a cutting head secured to, and extending away from, the distal end of the shaft, wherein (a) the cutting head is arcuate in shape so as to extend around only a section of the circumference of the elongated shaft defining the open end of the bore, and (b) the cutting head comprises a plurality of linear cutting teeth that extend along the length of the cutting head.
A finishing rasp for use during a surgical procedure to implant an orthopaedic hip prosthesis, comprising:
- an elongated shaft having a bore formed therein, the bore having (i) an open end defined in a distal end of the elongated shaft, and (ii) a blind end positioned proximally of the open end within the elongated shaft,
- a handle secured to an opposite, proximal end of the elongated shaft, and
- a cutting head secured to, and extending away from, the distal end of the shaft, the cutting head comprising a plurality of linear cutting teeth that (i) extend along the length of the cutting head and, (ii) are configured to cut bone tissue when the cutting head is advanced with oscillating motion in two directions.
A method of performing a surgical procedure to implant an orthopaedic hip prosthesis, comprising:
- advancing a reamer into an intramedullary canal of a patient's femur to ream the bone tissue of the femur,
- installing a reamer guide shaft to the proximal end of the reamer positioned in the intramedullary canal of a patient's femur,
- installing a finishing rasp over the reamer guide shaft, and
- oscillating the finishing rasp back and forth so as to remove bone tissue from the patient's femur.
A method of performing a surgical procedure to implant an orthopaedic hip prosthesis, comprising:
- implanting a distal stem component into an intramedullary canal of a patient's femur,
- installing a reamer guide shaft to the proximal end of the implanted distal stem component,
- installing a proximal reamer over the reamer guide shaft, the proximal reamer comprising a depth stop, and
- rotating the proximal reamer so as to remove bone tissue from the patient's femur until the depth stop of the proximal reamer bottoms out on the reamer guide shaft.
