Abstract
An orthopaedic surgical instrument that includes an elongated body having a longitudinal axis extending through a distal end and a proximal end, and a plurality of cutting teeth are extending from a medial side of the elongated body. Each cutting tooth includes a first curved medial edge, and a curved outer surface that extends distally from the first curved medial edge to a second curved medial edge. When the instrument is viewed in a coronal plane, the curved outer surface of each medial cutting tooth extends parallel to the longitudinal axis of the elongated body.
Claims20
An orthopaedic surgical instrument for preparing a patient's humeral bone to receive an orthopaedic implant, the instrument comprising:
- an elongated body having a longitudinal axis extending through a distal end and a proximal end,
- a first plurality of cutting teeth extending outwardly from an anterior surface of the elongated body,
- a second plurality of cutting teeth extending outwardly from a posterior surface of the elongated body, and
- a plurality of medial cutting teeth extending from a medial side of the elongated body, each medial cutting tooth comprising (i) a first curved medial edge, and (ii) a curved outer surface that extends distally from the first curved medial edge to a second curved medial edge, wherein the curved outer surface of each medial cutting tooth extends parallel to the longitudinal axis of the elongated body when the instrument is viewed in a coronal plane.
An orthopaedic surgical instrument for preparing a patient's humeral bone to receive an orthopaedic implant, the instrument comprising:
- an elongated body having a longitudinal axis extending through a distal end and a proximal end, and
- a plurality of cutting teeth are extending from a medial side of the elongated body, each cutting tooth comprising (i) a first curved medial edge, and (ii) a curved outer surface that extends distally from the first curved medial edge to a second curved medial edge,
- wherein when the instrument is viewed in a coronal plane, (i) the curved outer surface of each medial cutting tooth extends parallel to the longitudinal axis of the elongated body, and (ii) an arced imaginary line is defined by the medial-most points of the second curved medial edges of the cutting teeth, and
- wherein the elongated body has a lateral surface positioned opposite the medial surface that is devoid of cutting teeth.
A method of preparing a patient's humeral bone to receive an orthopaedic implant, the method comprising:
- inserting an orthopaedic surgical instrument into the patient's humeral bone to define a cavity sized to receive the orthopaedic implant, the orthopaedic surgical instrument including (i) a plurality of medial cutting teeth positioned to define a curved medial surface in the patient's humeral bone, (ii) a plurality of anterior cutting teeth to define a first tapered groove of the cavity, and (iii) a plurality of posterior cutting teeth to define a second tapered groove on a posterior side, and
- inserting the orthopaedic implant into the cavity such that a first keel of the orthopaedic implant is received in the first tapered groove and a second keel of the orthopaedic implant is received in the second tapered groove, the orthopaedic implant further including a curved medial surface that substantially matches the curved medial surface defined by the plurality of medial cutting teeth of the orthopaedic surgical instrument.
