## Abstract

Bone plates for engaging bone members are described herein. The bone plates can receive one or more screws to secure the bone plates to an underlying bone member. The one or more screws can be inserted into bone plate holes that can be considered locking or non-locking. The bone plates described herein can have particular combinations of locking and/or non-locking holes. In addition, instruments such as distal and proximal aiming guides can accompany the bone plates to guide one or more screws into the bone plates.

## Claims

### Claim 1

A system for treating a fracture in a bone, comprising: an aiming arm having a proximal end, a distal end, a first side, and a second side, the aiming arm comprising a plurality of openings, wherein each of the plurality of openings is spaced at predetermined intervals between the proximal end and the distal end, a bone plate configured to engage the bone, the bone plate comprising a proximal end, a distal end, a head portion, a neck portion and a shaft portion, wherein the head portion comprises a first row of openings and a second row of openings for receiving one or more fasteners therein, wherein the shaft portion comprises at least one additional opening for receiving a fastener therein; an attachment guide operatively connected to the first side of the proximal end of the aiming arm, the attachment guide including at least one opening that is coaxial with an opening in the neck portion of the bone plate; an attachment post having a first and a second end, wherein the attachment post is operable to pass through the at least one opening in the attachment guide and the opening in the neck portion of the bone plate; wherein the first end of the attachment post is operatively connectable to the opening in the attachment guide and the second end is operatively connectable to the opening in the neck portion of the bone plate; and a proximal targeting guide comprising openings that are coaxial with the first row of openings and the second row of openings in the head portion of the bone plate.

### Claim 2 (depends on 1)

The system of claim 1, further comprising a threaded shaft that fits within an internal cavity in the in the attachment post.

### Claim 3 (depends on 2)

The system of claim 2, wherein the attachment post and the threaded shaft form a rigid connection between the bone plate and the attachment guide.

### Claim 4 (depends on 3)

The system of claim 3, wherein the second end of the attachment post includes at least one ball end pin and a stabilizing protrusion that engage with the neck portion of the bone plate to form a rigid connection between the threaded shaft, attachment post, and bone plate.

### Claim 5 (depends on 3)

The system of claim 3, wherein a bottom side of the at least one opening in the attachment guide is configured and dimensioned to receive a corresponding portion of the first end of the attachment post.

### Claim 6 (depends on 3)

The system of claim 3, further comprising an attachment nut configured and dimensioned to attach to a top side of the at least one opening in the attachment guide and the first end of the attachment post to form a rigid connection between the aiming arm, and the attachment post.

### Claim 7 (depends on 3)

The system of claim 3, wherein the aiming arm comprises a radiolucent material.

### Claim 8 (depends on 3)

The system of claim 3, further comprising a tissue protection sleeve having a proximal end and a distal end, wherein the proximal end is operatively connectable to one of the plurality of openings in the aiming arm and the distal end is operatively connectable to a corresponding coaxial opening in the shaft portion of the bone plate.

### Claim 9 (depends on 8)

The system of claim 8, wherein the tissue protection sleeve comprises a head having a flexible arm that engages with a recess in one of the openings in the aiming arm.

### Claim 10 (depends on 8)

The system of claim 8, wherein the tissue protection sleeve includes a retention ledge that is engageable with an undercut in one of the openings in the aiming arm.

### Claim 11 (depends on 1)

The system of claim 1, wherein the proximal targeting guide comprises two holes that align with two pegs on the head portion of the bone plate in order to align the openings of the proximal targeting guide with the first row of openings and the second row of openings in the head portion of the bone plate.

### Claim 12

An apparatus A system for treating a fracture in a bone, comprising: a bone plate configured to engage the bone, the bone plate comprising a proximal end, a distal end, a head portion, a neck portion and a shaft portion, wherein the shaft portion comprises holes operable to receive fasteners therein; an aiming arm having a substantially rectangular shaft having a proximal end and a distal end, the substantially rectangular shaft including holes that are coaxial with the holes in the shaft portion of the bone plate; an attachment guide extending away from a first side of the proximal end of the shaft of the aiming arm, the attachment guide configured and dimensioned so that a hole in the attachment guide is coaxial with a hole in the neck portion of the bone plate; a fastener that is operatively connected to the hole in the neck portion of the bone plate; and an attachment post that is operatively connected to the fastener, the neck portion of the bone plate, and the hole in the attachment guide to form a rigid connection between the aiming arm and the bone plate; and a proximal targeting guide operatively connected to the head portion of the bone plate, wherein the proximal targeting guide includes at least one hole that is coaxial with a hole in the head portion of the bone plate.

### Claim 13 (depends on 12)

The system of claim 12, further comprising an attachment guide extending away from an opposite side of the proximal end of the shaft of the aiming arm, the attachment guide configured and dimensioned so that a hole in the attachment guide is coaxial with a hole in the neck portion of the hone plate.

### Claim 14 (depends on 12)

The system of claim 12, wherein only the rigid connection between the aiming arm and the bone plate causes the holes in the substantially rectangular shaft of the aiming arm to be coaxial with the holes in the shaft portion of the bone plate.

### Claim 15 (depends on 12)

The system of claim 12, further comprising an attachment nut that operatively connects to the attachment post and the aiming arm to form a rigid connection.

### Claim 16 (depends on 12)

The system of claim 12, wherein the aiming arm comprises a radiolucent material.

### Claim 17 (depends on 12)

The system of claim 12, further comprising a tissue protection sleeve having a proximal end and a distal end, wherein the proximal end is operatively connectable to one of the holes in the aiming arm and the distal end is operatively connectable to a corresponding coaxial hole in the shaft portion of the bone plate.

### Claim 18 (depends on 17)

The system of claim 17, wherein the tissue protection sleeve includes a head that comprises a flexible arm that allows the sleeve to engage and disengage with a hole in the shaft of the aiming arm.
