Abstract

A surgical assembly for resecting a greater tubercle from a humerus of a patient during performance of a shoulder replacement procedure. The surgical assembly includes a cutting tool for resecting the greater tubercle from the humerus. The surgical assembly also includes a tool guide member having a tool guide surface defined therein. The tool guide surface is configured to position the cutting tool in a predetermined position relative to the greater tubercle of the humerus. A method of resecting a greater tubercle from a humerus of a patient during performance of a shoulder replacement procedure is also disclosed.

Claims

1. A surgical procedure, comprising:

advancing a broach into a medullary canal of a humerus;

securing a guide assembly to said broach while said broach is located within said medullary canal of said humerus; and

resecting at least a portion of a greater tubercle of said humerus that includes an insertion point for rotator cuff muscle tissue with a culling tool, said resecting step including guiding said culling tool with said guide assembly while (i) said guide assembly is secured to said broach, and (ii) said broach is located within said medullary canal of said humerus.

2. The surgical procedure of claim 1, wherein:

said guide assembly includes a tool guide member and a support block,

said securing step includes (i) attaching said support block to said broach, and (ii) attaching said tool guide member to said support block, and

said guiding step includes guiding said cutting tool with said tool guide member.

3. The surgical procedure of claim 2, wherein:

said support block includes a channel,

said tool guide member includes a projection, and

said projection is configured to mate with said channel in a dove-tail relationship.

4. The surgical procedure of claim 1, wherein:

said advancing step includes the step of advancing said broach into said medullary canal of said humerus so that a collar of said broach sits substantially flush with a resected surface of said humerus, and

said securing step includes the step of securing said guide assembly to said broach while said collar of said broach sits substantially flush with said resected surface of said humerus.

5. The surgical procedure of claim 2, wherein:

said support block has a passageway extending therethrough,

said broach has defined therein a bore having an internally threaded portion, and

said step of attaching said support block to said broach includes the step advancing an externally threaded fastener through said passageway of said support block and into threading engagement with said internally threaded portion of said bore defined in said broach.

6. A surgical procedure, comprising:

advancing a broach into a medullary canal of a humerus;

securing a guide assembly to said broach; and

;

guiding a cutting tool with said guide assembly so as to resect at least a portion of a greater tubercle of said humerus while (i) said guide assembly is secured to said broach, and (ii) said broach is located within said medullary canal of said humerus that includes an insertion point for rotator cuff muscle tissue.

7. The surgical procedure of claim 6, wherein:

said guide assembly includes a tool guide member and a support block,

said securing step includes (i) attaching said support block to said broach, and (ii) attaching said tool guide member to said support block, and

said guiding step includes guiding said cutting tool with said tool guide member.

8. The surgical procedure of claim 7, wherein:

said support block includes a channel,

said tool guide member includes a projection, and

said projection is configured to mate with said channel in a dove-tail relationship.

9. The surgical procedure of claim 6, wherein:

said advancing step includes the step of advancing said broach into said medullary canal of said humerus so that a collar of said broach sits substantially flush with a resected surface of said humerus, and

said securing step includes the step of securing said guide assembly to said broach while said collar of said broach sits substantially flush with said resected surface of said humerus.

10. The surgical procedure of claim 7, wherein:

said support block has a passageway extending therethrough,

said broach has defined therein a bore having an internally threaded portion, and

said step of attaching said support block to said broach includes the step advancing an externally threaded fastener through said passageway of said support block and into threading engagement with said internally threaded portion of said bore defined in said broach.
