Abstract
Abstract A kit for performing surgical reconstruction of a shoulder separation using a device for visualizing the shoulder structure and particularly the clavicle and coracoid process. The kit includes a drill for drilling a hole through the clavicle and the coracoid process. A plurality of guide pins for insertion into the shoulder to define an initial entry position and angle for the drill. The kit also includes a device for reducing the separation between the clavicle and the coracoid process while providing a desired separation therebetween.

Claims Analysis
Total Claims: 28
Claim 1
Independent Claim
70 words
A method for surgically reconstructing a shoulder separation comprising inserting metal guide pins into the shoulder to bracket the coracoid process, drilling a first hole in the clavicle and a second hole in the coracoid process using the guide pins as a guide for the drill, inserting a screw through the first hole and into the second hole, and reducing the separation by screwing the clavicle to the coracoid process.
Claim 2
Independent Claim
70 words
A method for surgically reconstructing a shoulder separation comprising inserting metal guide pins into the shoulder to bracket the coracoid process, drilling a first hole in the clavicle and a second hole in the coracoid process using the guide pins as a guide for the drill, inserting a screw through the first hole and into the second hole, and reducing the separation by screwing the clavicle to the coracoid process.

The method of claim 2, wherein the step of inserting guide pins further includes inserting the first pin over the anterior edge of the clavicle and along the medial edge of the coracoid process, inserting the second pin over the anterior edge of the clavicle and along the lateral edge of the coracoid process, and inserting a third guide pin over the posterior edge of the clavicle and to the middle of the coracoid process.
Claim 7
Dependent Claim
19 words
The method of claim 2, wherein the drilling step includes aligning the drill generally parallel to the guide pins.
Claim 8
Dependent Claim
31 words
The method of claim 2, wherein the drilling step includes overdrilling the first hole in the clavicle to ensure that the first hole diameter is greater than the second hole diameter.
Claim 9
Independent Claim
107 words
A method of surgically reconstructing a shoulder separation comprising arranging means for visualizing the shoulder to visually display the shoulder structure on a screen, obtaining guide pins, which will show on the screen utilizing the visualizing means to determine the proper location of the guide pins, inserting the guide pins into the shoulder to bracket the coracoid process, drilling a first hole in the clavicle and a second hole in the coracoid process using the inserted pins as a guide for the drill, inserting a screw through the first hole and into the second hole, and reducing the separation by screwing the clavicle toward the coracoid process.
Claim 10
Independent Claim
107 words
A method of surgically reconstructing a shoulder separation comprising arranging means for visualizing the shoulder to visually display the shoulder structure on a screen, obtaining guide pins, which will show on the screen utilizing the visualizing means to determine the proper location of the guide pins, inserting the guide pins into the shoulder to bracket the coracoid process, drilling a first hole in the clavicle and a second hole in the coracoid process using the inserted pins as a guide for the drill, inserting a screw through the first hole and into the second hole, and reducing the separation by screwing the clavicle toward the coracoid process.
Claim 11
Dependent Claim
100 words
The method of claim 8, wherein the step of inserting guide pins includes inserting a first pin over the anterior edge of the clavicle and along the medial edge of the coracoid process, inserting a second pin over the anterior edge of the clavicle and along the lateral edge of the coracoid process so as to cooperate with the first pin to bracket the coracoid process, and inserting a third pin over the posterior edge of the clavicle and into the middle of the coracoid process so as to cooperate with the first and second pins to define a triangle.
Claim 12
Dependent Claim
26 words
The method of claim 9, wherein the drilling step includes the step of using the center of the triangle as an entry point for the drill.
Claim 13
Dependent Claim
