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

1. An instrument assembly, comprising:

a screw locating instrument which is adapted to be secured to a hip screw, said screw locating instrument having a first recess defined therein;

a plate locating instrument which is adapted to be secured to a bone plate, said plate locating instrument having a second recess defined therein; and

an alignment instrument having an alignment member extending therefrom, wherein both said first recess and said second recess are adapted to receive said alignment member therein.

2. The instrument assembly of claim 1, said plate locating instrument is further adapted to be secured to said bone plate prior to implantation of said bone plate into a body of a patient.

3. The instrument assembly of claim 1, wherein said screw locating instrument is further adapted to be secured to said hip screw prior to implantation of said hip screw into a body of a patient.

4. An orthopaedic implant and instrument assembly, comprising:

a bone screw which is adapted to be screwed into a bone,

a bone plate which is adapted to be secured to said bane screw,

a first instrument which is adapted to be secured to said bone screw, said first instrument having a first recess defined therein;

a second instrument which is adapted to be secured to said bone plate, said second instrument having a second recess defined therein; and

a third instrument having an alignment member extending therefrom, wherein both said first recess and said second recess are adapted to receive said alignment member therein.

5. The instrument assembly of claim 4, wherein said first instrument is further adapted to be secured to said bone screw prior to implantation of said bone screw into a body of a patient.

6. The instrument assembly of claim 4, wherein said first instrument is to secured to said bone screw subsequent to implantation of said bone screw into a body of a patient.

7. The instrument assembly of claim 4, wherein:

said bone screw has a flange secured thereto,

said bone plate has a channel defined therein, and

said flange is aligned with said channel when (i) said bone screw is secured to said first instrument, (ii) said bone plate is secured to said second instrument, and (iii) said alignment member is received into both said first recess and said second recess.
