Abstract

A method includes inserting a first surgical device into an exposed first end of a first bone until a trailing end of the first surgical device is disposed adjacent to the first end of the first bone. A second surgical device is inserted into an exposed first end of a second bone while the first surgical device remains disposed within the first bone. A first portion of an implant is advanced into the second bone while being engaged with a passageway defined by the implant such that the implant is guided by the second surgical device. The second surgical device is removed from the second bone and from its engagement with the implant. The first bone is repositioned such that the first surgical device is aligned with the passageway defined by the implant, and the first bone is forced into engagement with a second portion of the implant.

First claim

What is claimed is:

1. A method, comprising:
inserting a first surgical device into an exposed first end of a first bone until a trailing end of the first surgical device is disposed adjacent to the first end of the first bone;
inserting a second surgical device into an exposed first end of a second bone while the first surgical device remains disposed within the first bone;
advancing a first portion of an implant into the second bone while being engaged with a central passageway defined by the implant that extends through an entirety of the implant such that the implant is guided by the second surgical device;
removing the second surgical device from the second bone and from its engagement with the implant;
repositioning the first bone such that the first surgical device is aligned with the passageway defined by the implant;
forcing the first bone into engagement with a second portion of the implant; and
removing the first surgical device from the first bone and its engagement with the implant.

2. The method of claim 1 , further comprising
forming an incision to gain access to a joint between the first bone and the second bone;
flexing the first bone relative to the second bone to expose the first end of the first bone and the first end of the second bone; and
resecting at least one of the first end of the first bone and the first and end of the second bone.

3. The method of claim 1 , wherein the first portion of the implant is a threaded portion and the second portion of the implant is a blade portion.

4. A method, comprising:
forming an incision to gain access to a joint between first and second bones;
flexing the first and second bones such that the first and second bones are disposed at an angle with respect to one another;
inserting a first surgical device into the first bone until a first end of the first surgical device is disposed adjacent to a first end of the first bone;
inserting a second surgical device into the second bone while the first surgical device remains disposed within the first bone;
advancing a first portion of an implant into the second bone while a central passageway defined by the implant is engaged with the second surgical device such that the implant is guided by the second surgical device;
removing the second surgical device from the second bone and from its engagement with the implant;
repositioning the first bone such that the first surgical device is aligned with the passageway defined by the implant;
forcing the first bone into engagement with a second portion of the implant; and
resecting an end of each the first and second bones prior to inserting the first and second surgical devices.

5. The method of claim 4 , further comprising removing the first surgical device from the first bone and its engagement with the implant.

6. The method of claim 4 , wherein the first bone is a middle phalange of a foot, and the second bone is proximal phalange of a foot.

7. The method of claim 6 , wherein the first portion of the implant is a threaded portion and the second portion of the implant is a blade portion.

8. A surgical method, comprising:
gaining access to a joint between a middle phalange and a proximal phalange;
inserting a first end of a first surgical device into a proximal end of the middle phalange;
advancing the first surgical device into the middle phalange and a distal phalange until a second end of the first surgical device is disposed adjacent to the proximal end of the middle phalange;
inserting a first end of a second surgical device into a distal end of the proximal phalange while the first surgical device remains disposed within the middle and distal phalanges;
advancing a first portion of an implant into the proximal phalange using the second surgical device as a guide;
removing the second surgical device;
inserting the first surgical device into a passageway defined by the implant while the first surgical device remains disposed within the middle and distal phalanges;
removing the first surgical device after a period of time and while the implant remains engaged with the proximal phalange and the middle phalange, and resecting an end of each of the middle phalange and the proximal phalange prior to inserting the first and second surgical devices;
advancing a second end of the first surgical device through the proximal phalange and into at least one of a metatarsal and a cuneiform; and
blunting the first end of the first surgical device.

9. The surgical method of claim 8 , wherein the passageway is a central passageway that extends through the entirety of the implant.

10. The surgical method of claim 8 , wherein the first portion of the implant is a threaded portion and the second portion of the implant is a blade portion.
