## Abstract

Instruments, implants, bone plates, systems and methods for correcting bone deformities and fractures in the lower extremity are disclosed. Specifically, targeting instruments, implants, bone plates, systems and methods used for correcting bone deformities and/or fractures in the foot are disclosed.

## Claims

### Claim 1

A surgical method, comprising:
inserting a guide pin into a bone;
securing a guide arm to the guide pin at a second end of the guide arm;
inserting a protector member into a first end of the guide arm;
inserting a target pin through at least two bone segments;
rotating the guide arm about a spherical component such that the first end of the guide arm is in a first position relative to a first bone segment of the at least two bone segments;
removing the protector member from the guide arm;
drilling a hole over the target pin; and
threading a target member into a drill hole to secure the at least two bone segment.

### Claim 2 (depends on 1)

The method of claim 1, wherein the at least two bone segments comprise at least one of a talus and a first metatarsal of a patient.

### Claim 3 (depends on 1)

The method of claim 1, wherein the guide pin comprises the spherical component disposed at a position along a length of the guide pin.

### Claim 4 (depends on 3)

The method of claim 3, wherein the guide arm comprises a housing element;
wherein securing the guide arm to the guide pin comprises coupling the housing element with the spherical component of a guide wire.

### Claim 5 (depends on 1)

The method of claim 1, further comprising inserting the protector member into a through hole of the first end of the guide arm.

### Claim 6 (depends on 1)

The method of claim 1, further comprising inserting the target pin through the protector member and into at least one of the first bone segment and the second bone segment of the at least two bone segments.

### Claim 7 (depends on 6)

The method of claim 6, wherein the guide pin is inserted at a first trajectory and the target pin is inserted at a second trajectory;
wherein the first and second trajectories overlap.

### Claim 8 (depends on 7)

The method of claim 7, wherein the guide pin and the second trajectory engage one another.

### Claim 9 (depends on 1)

The method of claim 1, further comprising coupling an implant holder to the guide arm.

### Claim 10 (depends on 9)

The method of claim 9, further comprising coupling a bone plate with the implant holder and aligning the implant holder adjacent at least one of the first bone segment and the second bone segment of the at least two bone segments.

### Claim 11 (depends on 10)

The method of claim 10, further comprising adjusting a position of the bone plate to a desired position in a first plane along relative to the guide arm.

### Claim 12 (depends on 11)

The method of claim 11, further comprising rotating the guide arm about the guide pin to adjust the position of the bone plate to a desired position in a second plane relative to the guide arm.

### Claim 13 (depends on 12)

The method of claim 12, wherein the desired position of the bone plate in the first and second planes relative to the guide arm is configured to position one or more through holes of the bone plate to accommodate one or more fixation components therethrough at a trajectory to avoid contacting the target pin.

### Claim 14 (depends on 13)

The method of claim 13, further comprising securing the bone plate to at least one of the first and second bone segment such that the one or more fixation components avoid contacting the targeting pin or a path of a threaded member.

### Claim 15

A surgical method, comprising:
inserting a guide pin into a bone;
securing a guide arm to the guide pin at a second end of the guide arm;
inserting a protector member into a first end of the guide arm;
inserting a target pin through at least two bone segment;
removing the protector member from the guide arm;
coupling a bone plate with an implant holder coupled to the guide arm;
adjusting the bone plate along a length of the guide arm in a first plane;
drilling a hole over the target pin; and
threading a target member into a drill hole to secure the at least two bone segments.

### Claim 16 (depends on 15)

The surgical method of claim 15, further comprising:
rotating the guide arm around the guide pin to rotate the bone plate in a second plane.
