## Abstract

Provided is an apparatus and component parts of a system for the external fixation of bones. The component parts include fixation plates such as a J-shaped Plate and an I-shaped Plate. Two or more fixation plates are configured along an axis, the two or more fixation plates; a plurality of telescoping adjustable struts that connect a first fixation plate along the axis with a second fixation plate of the plurality of fixation plates along the axis, wherein the first and second fixation plates are adjacent plates along the axis; and a plurality of posts, each post connecting two adjacent fixation plates of the plurality of fixation plates along the axis.

## Claims

### Claim 1

An apparatus for the external fixation of bones, comprising:
a plurality of two or more fixation plates configured along an axis, the two or more fixation plates comprising a plurality of J-shaped Plates, the plurality of J-shaped Plates each comprising:
a curved portion; and
a straight portion;
a plurality of telescoping adjustable struts that connect a first fixation plate of the plurality of fixation plates along the axis with a second fixation plate of the plurality of fixation plates along the axis, wherein the first and second fixation plates are adjacent plates along the axis.

### Claim 2 (depends on 1)

The apparatus of claim 1, the plurality of two or more fixation plates further comprising an I-shaped Plate.

### Claim 3 (depends on 1)

The apparatus of claim 1, the plurality of two or more fixation plates further comprising a Foot Plate.

### Claim 4 (depends on 3)

The apparatus of claim 3, further comprising:
a plurality of posts coupled to the Foot Plate; and
a plurality of bridges, each bridge coupled at an end to a corresponding post and coupled at an opposite end to the second fixation plate.

### Claim 5 (depends on 1)

The apparatus of claim 1, further comprising:
a plurality of holes in each of the plurality of fixation plates; and
a plurality of fixation devices selected from a fixation list, the fixation list comprising:
a plurality of pins; and
a plurality of wires;
wherein each fixation device of the plurality of fixation devices is coupled to at least one hole of the plurality of holes and configured to secure a bone within the plurality of fixation plates.

### Claim 6 (depends on 5)

The apparatus of claim 5, wherein the plurality of holes in each fixation plate comprise a double row of holes.

### Claim 7 (depends on 1)

The apparatus of claim 1, each of the plurality of telescoping adjustable struts comprising a plurality of swivel hinges for attaching to the fixation plates.

### Claim 8

A system for the assembly of a customized orthopedic external bone fixation device, comprising:
a plurality of fixation plates comprising a plurality of J-shaped Plates, the plurality of J-shaped Plates each comprising:
a curved portion; and
a single straight portion; and
a plurality of coupling devices, comprising a plurality of adjustable telescoping struts;
wherein each of the coupling devices is configured to affix a first fixation plate of the plurality of fixation plates along the axis with a second fixation plate of the plurality of fixation plates along the axis; and
wherein the first and second fixation plates are adjacent plates along the axis.

### Claim 9 (depends on 8)

The system of claim 8, the plurality of fixation plates further comprising a plurality of I-shaped Plates.

### Claim 10 (depends on 8)

The system of claim 8, the plurality of fixation plates further comprising a Foot Plate.

### Claim 11 (depends on 8)

a plurality of holes in each of the plurality of fixation plates; and
a plurality of pins, each pin coupled to at least one hole of the plurality of holes, adapted to secure a bone within the plurality of fixation plates.

### Claim 12 (depends on 11)

The system of claim 11, Wherein the plurality of holes in each fixation plate comprise a double row of holes.

### Claim 13 (depends on 8)

The system of claim 8, further comprising:
a plurality of pins; and
a plurality of wires,
wherein the pins and wires are for securing a bone within the plurality fixation plates.

### Claim 14 (depends on 8)

The system of claim 8, each of the plurality of adjustable telescoping struts comprising a plurality of swivel hinges for attaching the struts to the fixation plates.

### Claim 15

A J-shaped Plate for use with an external bone fixation device, comprising:
a semi-circular plate, wherein the plate covers an arc of between ninety degrees (90°) and one hundred eighty degrees (180°); and
a straight extension at an end of the arc; and
wherein the semi-circular plate and the extension comprise:
