Abstract

A method of percutaneously implanting a first component and a second component of an orthopaedic assembly into a body of a patient includes the steps of securing a first instrument to the first component, and advancing the first component into the body of the patient. The first instrument is advanced into the body of the patient such that a portion of the first instrument extends out of the body. A second instrument is secured to the second component, and the second component is advanced into the body of the patient. The second instrument is advanced into the body of the patient such that a portion of the second instrument extends out of the body. A third instrument is advanced into contact with both the first instrument and the second instrument so as to position the first component and the second component in a predetermined position relative to one another. An instrument assembly for percutaneously implanting an orthopaedic assembly is also disclosed.

Claims (38)

1. A method of percutaneously implanting a first component and a second component of an orthopaedic assembly into a body of a patient, comprising the steps of:

securing a first instrument to said first component,

advancing said first component into said body,

advancing said first instrument into said body such that a portion of said first instrument extends out of said body,

securing a second instrument to said second component,

advancing said second component into said body,

advancing said second instrument into said body such that a portion of said second instrument extends out of said body, and

advancing a third instrument into contact with both said first instrument and said second instrument so as to position said first component and said second component in a predetermined position relative to one another,

wherein said step of advancing said first component into said body includes the step of securing said first component to a bone within said body, and

said step of advancing said third instrument into contact with both said first instrument and said second instrument includes the step of moving said second component into contact with said first component.

2. The method of claim 1 , wherein said step of securing said first instrument to said first component is performed prior to said step of advancing said first component into said body.

3. The method of claim 1 , wherein said step of securing said first instrument to said first component is performed subsequent to said step of advancing said first component into said body.

4. A method of percutaneously implanting a first component and a second component of an orthopaedic assembly into a body of a patient, comprising the steps of:

securing a first instrument to said first component,

advancing said first component into said body,

advancing said first instrument into said body such that a portion of said first instrument extends out of said body,

securing a second instrument to said second component,

advancing said second component into said body,

advancing said second instrument into said body such that a portion of said second instrument extends out of said body, and

advancing a third instrument into contact with both said first instrument and said second instrument so as to position said first component and said second component in a predetermined position relative to one another,

wherein (i) said first component includes a bone screw, (ii) said second component includes a bone plate, (iii) said step of advancing said first component into said body includes the step of screwing said bone screw into a bone within said body, and (iv) said step of advancing said third instrument into contact with both said first instrument and said second instrument includes the step of moving said bone plate into engagement with said bone screw.

5. The method of claim 4 , wherein:

said bone screw has a flange secured thereto,

said bone plate has a channel defined therein, and

said step of advancing said third instrument into contact with both said first instrument and said second instrument includes the step of moving said flange into said channel.

6. The method of claim 4 , wherein said step of securing said first instrument to said first component is performed prior to said step of advancing said first component into said body.

7. The method of claim 4 , wherein said step of securing said first instrument to said first component is performed subsequent to said step of advancing said first component into said body.

8. A method of percutaneously implanting a first component and a second component of an orthopaedic assembly into a body of a patient, comprising the steps of:

securing a first instrument to said first component,

advancing said first component into said body,

advancing said first instrument into said body such that a portion of said first instrument extends out of said body,

securing a second instrument to said second component,

advancing said second component into said body,

advancing said second instrument into said body such that a portion of said second instrument extends out of said body, and

advancing a third instrument into contact with both said first instrument and said second instrument so as to position said first component and said second component in a predetermined position relative to one another,

wherein (i) said first instrument has a first recess defined therein, (ii) said second instrument has a second recess defined therein, (iii) said third instrument has an alignment member extending therefrom, and (iv) said step of advancing said third instrument into contact with both said first instrument and said second instrument includes the step of advancing said alignment member into both said first recess and said second recess.

9. The method of claim 8 , wherein said step of securing said first instrument to said first component is performed prior to said step of advancing said first component into said body.

10. The method of claim 8 , wherein said step of securing said first instrument to said first component is performed subsequent to said step of advancing said first component into said body.
