Abstract
A number of orthopaedic surgical instruments for use in a surgical procedure to prepare a patient's femur to receive an orthopedic prosthesis are disclosed. The tools include guide tools, cutting tools, surgical blocks, and other orthopaedic surgical instruments configured to plan and guide the preparation of the patient's femur. A method of using the orthopaedic surgical instruments is also disclosed.
Claims20
A method of surgically preparing a patient's femur to receive an orthopaedic prosthesis, the method comprising:
- attaching a stem trial to a proximal end of an offset tool,
- advancing the stem trial through a distal surface of the patient's femur into a distal end of a medullary canal,
- positioning a surgical block on a distal surface of the patient's femur,
- attaching the surgical block to a distal end of the offset tool,
- rotating the distal end of the offset tool relative to the stem trial to move the surgical block on the distal surface of the patient's femur,
- preventing rotation of the distal end of the offset tool when the surgical block is in a desired offset orientation,
- advancing a cannulated reamer over the distal end of the offset tool,
- reaming the patient's femur with the cannulated reamer to define a chamber at the distal end of the medullary canal,
- removing the stem trial from the medullary canal, and
- inserting an intramedullary orthopaedic surgical instrument into the chamber and the medullary canal of the patient's femur, the intramedullary orthopaedic surgical instrument including the stem trial.
A method for performing an orthopaedic surgical procedure on a patient's femur, the method comprising:
- securing a distal end of an intramedullary orthopaedic surgical instrument to a proximal end of an intramedullary adaptor,
- rotating a first adaptor body of the intramedullary adaptor to a desired offset orientation relative to a second adaptor body of the intramedullary adaptor,
- advancing the intramedullary orthopaedic surgical instrument and the proximal end of the intramedullary adaptor through a distal surface of the femur, and
- positioning a surgical block secured to the distal end of the intramedullary adaptor on the distal surface of the femur.
A method for performing an orthopaedic surgical procedure on a patient's femur, the method comprising:
- positioning an intramedullary orthopaedic surgical instrument in a medullary canal of the patient's femur,
- positioning a reamer guide assembly on a distal surface of the patient's femur in a desired offset orientation relative to the intramedullary orthopaedic surgical instrument,
- advancing a cannulated reamer over a shaft of the reamer guide assembly to ream the patient's femur at the desired offset orientation,
- removing the intramedullary orthopaedic surgical instrument from the medullary canal of the patient's femur after reaming,
- securing the intramedullary orthopaedic surgical instrument to a proximal end of an intramedullary adaptor,
- positioning a first adaptor body of the intramedullary adaptor relative to a second adaptor body of the intramedullary adaptor based on the desired offset orientation,
- inserting the intramedullary orthopaedic surgical instrument and the proximal end of the intramedullary adaptor into the patient's femur, and
- operating a locking mechanism to permit a distal end of the intramedullary adaptor to rotate relative to the first adaptor body.
