Introduction

The Biomet Vision Unilateral Fixator is an external fixation

device intended for use in the treatment of bone conditions

including leg lengthening, osteotomies, arthrodesis and fracture

fixation addressing periarticular, diaphyseal and other fractures

amenable to temporary or definitive external fixation.

The Biomet Vision Unilateral Fixator incorporates

lightweight carbon fiber materials into its frame to allow for

unobstructed fracture visualization and provide optimal fixation.

The system includes multiple frame configurations

- the Standard Fixator, Ankle Fixator, Variable Ankle Fixator and

Arc Clamp with Standard Fixator - that all share a unique carbon

central body design. The radiolucent central body includes

serrated rotational and dual locking connectors with locking

connector bolts that provide a mechanical locking mechanism

with up to 120° of controlled fracture reduction in any plane.

Standard Fixator Technique

Step #1

Pre-operative planning is recommended prior to the application

of this device. Assess potential screw site location based on

available bone stock and soft tissue considerations. Additional

modules may be utilized for horizontal screw placement or

fracture specific applications. Selected screw sites must

accommodate the length of the central body components. All

constructs should include at least one telescoping fixator clamp

that should be positioned parallel to the long axis of the bone

to which it is to be secured. Axial alignment of the telescoping

fixator arm helps assure free excursion (compression/distraction).

Fixator components are used as templates. Prep and drape in

routine fashion.

Figure 1

Step #2

Obtaining a preliminary reduction is recommended. Templating

with the fixator body, adjust the rotational locking connector

to avoid limb interference with bolts. Add or remove knuckles

to gain length or accommodate unusually short limbs. The

first bone screw is generally inserted in the shortest or most

difficult fragment. Assess available bone stock for desired screw

position. (Figures 1 & 2)

NOTe: When possible, allow 4cm of distance between fracture

site and first bone screw.

Figure 2

Step #3

A 1cm incision is made and blunt dissection continued to bone.

(Figure 3)

Figure 3

Page 12: Biomet Vision Unilateral Fixator Surgical Technique...Additional indications for the Biomet® Vision FootRing System, a sub system of the DynaFix Vision External Fixation System include:

Standard Fixator Technique (Continued)

Step #4

The trocar and appropriate length soft tissue guide are then

utilized to identify the center of the bone and to establish the

orientation of the screw tract to be pre-drilled. The orientation

of the insertion of the bone screws should be perpendicular to

the long axis of the bone. (Figure 4) Site of proximal screws is

predicated by the proximal screw clamp. Place the fixator over

the proximal limb area and template all screws outside the zone

of soft tissue injury to prevent contamination of fracture through

the screw.

NOTe: Allow a minimum of 4cm of distance between fracture site

and first bone screw.

Figure 4

Step #6

The soft tissue guide is tapped with a mallet to engage the soft

tissue guide with bone. (Figure 5)

Figure 6

Step #7

Insert appropriate drill guide into the soft tissue guide. (Figure 6)

NOTe:

Drill Guide Drill Bit Screw

4.8mm 4.8mm 6/5mm (Cortical)

3.2mm 3.2mm 6/5mm (Cancellous)

3.2mm 3.2mm 4.5/3.5mm (Cortical)

2.9mm 2.9mm 3.5/3.2mm (Cortical)Step #5

Once the screw site is selected, use gentle pressure to maintain

contact between the soft tissue guide and the cortex of the bone.

Extract the trocar.

Figure 5

11

Step #8

Insert matching drill bit with drill stop into the drill guide. Drill the

near cortex. Drilling is halted upon contact with the far cortex. Be

sure pre-drilled screw tract is perpendicular to the long axis of

the bone. (Figure 7)

Figure 8

Step #10

After bi-cortical penetration of the drill, the drill bit and drill guide are

withdrawn. Maintain contact and position of the soft tissue guide.

Figure 10

Step #11

The appropriate length screw is then inserted through the soft

tissue guide. The bone screw T-Wrench (Catalog #03125) is used

to advance the screw into bone. To obtain optimal purchase,

all bone screws must be bi-cortical with no less than 2mm

protruding from the far cortex and about 5mm remaining outside

the near cortex. Image intensification is utilized to confirm depth

of penetration. (Figure 10)

For short segment, clamp bone screw holes 1 & 3, 3 & 5 or 2 & 4

may be selected. Translocation of clamp on pin cluster is possible

(as necessary).

NOTe: Care must be taken to avoid over-penetration. Due to the

tapered design, bone screws must not be backed out or they will

lose purchase.

Step #9

Upon contact with the far cortex, the drill stop is re-positioned and

secured approximately 5mm from the base of the drill guide. The

drill stop will prevent over penetration of the drill bit into underlying

soft tissue structures. The far cortex is then drilled. (Figures 8 & 9)

Step #12

Loosen the clamp cover locking bolts of the fixed clamp such that

the soft tissue guide and existing bone screw are accommodated.

At this point, a second bone screw may be introduced into the

same female clamp to insure a parallel relationship of the fixed

clamp to bone. Repeat steps 3-11 making sure to snug down

the female clamp cover locking bolts to prevent toggle of the soft

tissue guides within the clamp. This helps maintain proper bone

screw alignment. (Figure 11)

Step #13

It is also possible at this point to address the opposing bone

screw cluster. The locking connector bolts and locking setscrews

are provisionally tightened. Proceed to opposite telescoping fixator

clamp. Identify and secure screw placement following steps 3-11.

Align telescoping fixator clamp and fixed clamp such that they are

parallel to the long axis of the bone into which they are inserted.

Insert soft tissue guide and trocar, snug down clamp cover

locking bolts, and proceed with subsequent bone screw insertion

steps 3-11. (Figure 12)

NOTe: Ensure at least 1cm of space is between telescoping cover and straight clamp.

Step #14

Remove soft tissue guides and tighten clamp cover locking bolts

providing at least 3cm clearance between fixator body and skin

surface. (Figure 13)

Use of a Torque Wrench (90in-lbs) is required to ensure proper locking of the system. Use of traditional 5mm Allen Wrench or T-Wrench is prohibited, as this may result in undue stress to the carbon fiber materials. (Figure 14)

Step #15

Final reduction may be addressed systematically. Length is

accomplished by distracting (manually or incrementally) the CD

mechanism from the telescoping fixator clamp in the direction of

the arrow, counterclockwise. (Figure 15)

NOTe: For angular or translational adjustments there should be a

corresponding adjustment in length.

Figure 15

Turn counterclockwise to distract

NOTe: If distraction (or compression) is desired, the proximal locking setscrew must first be definitively tightened with a torque wrench.

NOTe: If distraction (or compression) is desired, ensure the two distal locking setscrews are NOT definitively tightened. Upon desired distraction, lock the setscrews with a torque wrench.

Step #16

Rotation about the axis of the fixator may be achieved by

releasing the locking setscrew of the rotational locking connectors

(male). (Figure 16)

Step #17

Each dual locking connector will provide angular adjustments

in two planes relative to fixator position as applied to the bone.

Utilize the dual locking connector most adjacent to fracture for

angular corrections. (Figures 17 & 18)

Step #18

Translational adjustment is performed by releasing two opposing

dual locking connectors in the same plane as desired correction.

Translation can also be addressed by utilizing the half pins

already inserted into the bone to be translated. (Figure 19)

Arc Clamp With Standard Fixator Technique

15

The arc clamp may be substituted for either a telescoping fixator

clamp or a fixed clamp component from the Standard Fixator,

where horizontal bone screw placement is desired.

Attach the arc clamp (female) coupler to the rotational locking

connector (male) and secure the single locking setscrew with a

torque wrench.

The arc clamp offers two silver template clamps (Figure 20)

to allow for soft tissue instrumentation during bone screw

application. Additionally, the two black bone screw clamps will

secure the bone screws.

The arc clamp should be applied following steps 3-11

(page 9-11) from Standard Fixator Technique. Assess

selected diaphyseal screw sites to assure a parallel relationship

between telescoping fixator clamp (or fixed clamp) and the bone.

Insert diaphyseal bone screws following steps 3-12 (page 9-12)

from Standard Fixator Technique. Obtain reduction and definitively

tighten all fixator-locking bolts with a torque wrench.

NOTe: Use of a Torque Wrench (90in-lbs) is required to ensure

proper locking of the system. Use of traditional 5mm Allen

Wrench or T-Wrench is prohibited, as this may result in undue

stress to the carbon fiber materials.

Step #1

After achieving a preliminary pre-op reduction, the first screw

to be introduced should be positioned medially in the talar neck,

so that it is parallel to the dome of the talus following steps 3-9

(pages 9-11) of Standard Fixator Technique. (Figure 21)

NOTe: If using Variable Ankle Fixator, reference page 20 for

first screw insertion detail

Step #2

After bi-cortical penetration, release the 3.2mm drill bit and

evaluate its position fluoroscopically to confirm a parallel

relationship to the talar dome. Reattach drill bit to drill and

extract. After bi-cortical penetration of the drill, the drill bit and

drill guide are withdrawn. Maintain contact and position of the

soft tissue guide.

Step #3

Attach the ankle clamp onto the talar bone screw and screw

guide with the window of the device positioned medially and

anterior to facilitate lateral radiographic evaluation. Clamp cover

locking bolts of the ankle clamp must be facing distally for

access to locking components. (Figure 22)

Step #4

Using the ankle clamp as a template, select second screw position

in the calcaneus allowing for desired plantar/dorsi flexion. Repeating

steps 3-11 (pages 9-11) of Standard Fixator Technique, insert

second bone screw. Confirm bone screw position and depth of

penetration utilizing image intensification. (Figure 22)

Step #5

Spatially relocate the talus under the tibia and position remaining

bone screws through the telescoping fixator arm in the tibial diaphysis

perpendicular to the long axis of the tibia. Secure clamp cover locking

bolts (Figure 23) with a torque wrench for definitive tightening.

Step #10

The pivot bolt on the ankle clamp is tightened in the direction

of the yellow arrow etched on the clamp with use of the 4mm

T-Wrench (Catalog #21020) only. (Figure 30)

NOTe: (Cortical Screws placed in Cancellous Bone) When placing

a cortical screw into the neck of the talus, you will start with a soft

tissue sleeve and a 3.2mm drill guide placed in the appropriate

location on the neck of the talus. Under power a 3.2mm drill bit will

be drilled through the medial cortex and through the lateral cortex.

Next, remove the 3.2mm drill sleeve and replace it with a 4.8mm

drill sleeve. Under power a 4.8mm drill bit will be used to drill

through the medial cortex only. The 4.8mm drill sleeve is removed

and the appropriate 6/5mm cortical bone screw is inserted into the

soft tissue sleeve. The screw is inserted past the lateral cortex by

two threads. The talus and calcaneus portion of the ankle clamp is

attached to the screw that is in place in the neck of the talus. A soft

tissue sleeve and 3.2mm drill sleeve is placed in the calcaneus part

of the ankle clamp and the procedure is repeated in the calcaneus.

NOTe: For left application, tighten counterclockwise, as shown

(Figure 31). For right application, tighten clockwise.

This is the only portion of the ankle clamp that requires use

of a 4mm T-Wrench (Catalog #21020) for definitive tightening.

Do not use the Torque Wrench to tighten.

The Biomet Vision Unilateral Fixator is shipped fully assembled,

but can be adjusted to accommodate a desired length.

Removing A Dual Locking Connector

• To remove a dual locking connector, two locking bolts must be fully removed

• While removing the locking bolts, components should not be held together, but rather should be apart so that threads are only engaged with a single component at a time

• With the two locking bolts removed the dual locking connector is put aside and the frame can be reassembled

• To reassemble the frame, the locking bolt should be fully threaded through the remaining dual locking connector before it engages the threaded component of the rotational locking connector or dual locking connector

• By fully threading the locking bolt through the first component before engaging the second, you will ensure proper seating of the bolt to secure the components together

• This step is repeated to connect the other half of the dual locking connector

• All locking components should be facing away from the extremity to which the frame is applied. This will ensure that you have access to definitively lock all components once the frame is properly positioned

Correct Incorrect

NOTe: Locking connector bolt should be flush against the dual locking connector when turning counterclockwise to remove.

Adding A Dual Locking Connector

• To add a dual locking connector, one locking bolt must be fully removed

• While removing the locking bolts, components should not be held together, but rather should be apart so that threads are only engaged with a single component at a time

• With the locking bolt removed, the frame can be reassembled with the additional dual locking connector

• To reassemble the frame, the locking bolt should be fully threaded through the remaining dual locking connector before it engages the threaded component of the rotational locking connector or dual locking connector

• By fully threading the locking bolt through the first component before engaging the second, you will ensure proper seating of the bolt to secure the components together

• This step is repeated to connect the other half of the dual locking connector

• All locking components should be facing away from the extremity to which the frame is applied. This will ensure that you have access to definitively lock all components once the frame is properly positioned

Suggested Screw Site Care/Sterilization

At the conclusion of fixator application and fracture reduction,

wounds are dressed in routine sterile fashion. Care should

be taken to ensure all fixator fittings are securely tightened.

Dry sterile gauze is wrapped around the shanks of the bone

screws to prevent pistoning of the soft tissues on the bone

screws. Once wounds have healed and sutures are removed,

routine postoperative screw site care is recommended. Screw

sites should be monitored during subsequent clinic visits.

All fixator fittings should be evaluated for tightness during

subsequent clinic visits.

The Biomet Vision Unilateral Fixator is provided nonsterile

and must be sterilized prior to use. Repeated sterilization of

carbon fiber reinforced epoxy is not recommended.

All packaging materials must be removed prior to sterilization.

All fixator components should be sterilized in a loosened state

such that components may move freely.

The following steam sterilization parameters are recommended.
