Abstract

A number of orthopaedic surgical instruments are also disclosed. A method, apparatus, and system for fabricating such instruments are also disclosed.

Claims

1. An orthopaedic bone saw for cutting the bone of a patient, comprising:

a chuck configured to receive a bone saw blade, and

a guide configured to receive one or more surgical guide pins therein to align the bone saw in a predetermined position relative to the bone of the patient.

2. The bone saw of claim 1, wherein the guide comprises a body having one or more openings defined therein to receive the one or more surgical guide pins.

3. The bone saw of claim 1, wherein:

the guide comprises an elongated body having a slot defined therein, and

the slot is configured to receive the one or more surgical guide pins therein.

4. The bone saw of claim 1, further comprising a swivel secured to the guide, wherein the swivel permits the chuck and the guide to swivel relative to one another.

5. The bone saw of claim 4, further comprising a handle and a housing secured to the handle, wherein:

the chuck is secured to the housing,

the swivel is positioned between the housing and the guide, and

the guide swivels relative to the housing.

6. The bone saw of claim 1, further comprising a handle and a housing secured to the handle, wherein the chuck and the guide are secured to the housing.

7. An orthopaedic bone saw tool for cutting the bone of a patient, comprising:

a bone saw having (i) a housing, (ii) a handle secured to the housing, (iii) a chuck secured to the housing, and (iv) a guide configured to receive one or more surgical guide pins secured to the housing, and

a bone saw blade secured to the chuck.

8. The bone saw tool of claim 7, wherein the guide comprises a body having one or more openings defined therein to receive the one or more surgical guide pins.

9. The bone saw tool of claim 7, wherein:

the guide comprises an elongated body having a slot defined therein, and

the slot is configured to receive the one or more surgical guide pins therein.

10. The bone saw tool of claim 7, wherein:

the bone saw further comprises a swivel positioned between the housing and the guide, and

the swivel permits the guide and the bone saw blade to swivel relative to one another.

11. A method of performing an orthopaedic surgical procedure on a bone of a patient, comprising:

inserting a first end of one or more surgical guide pins into the bone of the patient,

advancing a second end of the one or more surgical guide pins into a guide secured to a bone saw so as to position the bone saw in a predetermined position relative to the bone of the patient, and

making a cut in the bone of the patient with the bone saw while the one or more surgical guide pins are positioned in the guide.

12. The method of claim 11, wherein:

the guide comprises a body having one or more openings defined therein, and

advancing the second end of the one or more surgical guide pins comprises advancing the second end of the one or more surgical guide pins into the one or more openings.

13. The method of claim 11, wherein:

the guide comprises an elongated body having a slot defined therein, and

advancing the second end of the one or more surgical guide pins comprises advancing the second end of the one or more surgical guide pins into the slot.

14. The method of claim 11, wherein:

the bone saw comprises (i) a chuck having a bone saw blade secured thereto, and (ii) a swivel positioned between the chuck and the guide, and

making a cut in the bone of the patient comprises swiveling the chuck relative the guide while making the cut in the bone of the patient.

15. The method of claim 11, wherein inserting the first end of one or more surgical guide pins into the bone of the patient comprises:

positioning a customized patient-specific cutting block in contact with the bone of the patient,

inserting the first end of the one or more surgical guide pins through one or more guide pin holes defined in the customized patient-specific cutting block and into the bone of the patient, and

removing the customized patient-specific cutting block from the bone of the patient without removing the one or more surgical guide pins from the bone of the patient.
