Seminar TF Design – General Information 1

Notes

Otto Bock TF Design When working on jobs in the Otto Bock TF Design software, you go

through four program stages, each of which has a tab in the TF Design

processing window:

Specification Selection of the socket-specific data and entry of the patient

measurements. In order to enter the patient measurements, you

have to previously determine the exact values with the patient.

Socket View

Three-dimensional view of the calculated prosthesis socket, with the

option to make corrections.

Component Selection

Selection of components for the prosthesis.

Ordering

Display and editing of the purchase order for the current job.



Notes

Because every socket design is based on relatively few measurements,

it is important that these measurements are taken carefully.

Repeating each measurement once or twice is recommended in order

to ensure that the values obtained are reliable.

Make a note of all measurements taken so you can subsequently

enter them in the software.

Before you begin working with the Otto Bock TF Design application,

take the following patient measurements:

Residual limb length

Residual limb circumference

Measurements with liner

Bony ML dimension

Soft tissue ML dimension



Notes

Residual Limb Length

Measure the length of the residual limb from the ischial

tuberosity to the end of the residual limb.

This residual limb length measurement is used to define the

length of the residual limb.

The definitive socket length can be increased, as may be

required in case of a femur end that is not well covered with soft

tissue (Fig. 1).



Notes

Palpate the skin in order to place the body caliper firmly against

the ischial tuberosity. The residual limb musculature must be relaxed

when doing so, in order to keep the body caliper from slipping off.

Exert only light pressure on the end of the residual limb when

determining the length of the residual limb.

Use the Otto Bock Body Caliper 743S10, which will provide you

with a reliable residual limb length measurement.

Take the measurement along the residual limb axis.

If the residual limb is in a highly abducted position, tilt the body

caliper accordingly.



Notes

Residual Limb Circumference

The most proximal circumference is determined 30 mm below the level

of the ischial tuberosity.

The residual limb length is already set on the body caliper.

Using the body caliper, mark the position of the first

circumference measurement (30 mm below the ischial tuberosity,

that is, lower edge of the caliper edge, see arrow in Fig. 2) and the

intervals on the lateral side.



Notes

Take addition circumference measurements between the initial

measurement (30 mm below the ischial tuberosity) and the last distal

measurement (50 mm from the end of the residual limb).

You are free to decide the interval between the measurements.

Attention

The distance from one circumference measurement to the next

must not be less than 30 mm (Fig. 3).



Notes

Take a total of no more than five measurements, including the initial

measurement and the last distal measurement (50 mm from the end of

the residual limb)

Attention

Additional measurements closer than 50 mm from the end of the

residual limb should not be taken, since the measurement

accuracy becomes very poor due to rounding of the residual

limb.

All measurements should represent the mean values of the muscles in

a tense and the muscles in a relaxed state.

When using measuring tape 743B1, try to keep the tension

constant while measuring or use the 743B4 spring-loaded

measuring tape.

Attention

Ensure that the measuring tape is horizontal in relation to the

axis of the residual limb.



Notes

Measurements with Liner

First determine the correct liner size according to the application

instructions provided by the manufacturer.

After selecting the right liner size, the liner is rolled over the

residual limb before measuring. The circumference and length are

now determined with the liner applied, as previously described under

Residual Limb Circumference.

Applying the liner compresses the residual limb and therefore

causes a volume reduction.

Therefore we recommend not to apply any further reduction in

the software and to evaluate the reduction at 0%.

The exact socket length measurement is also determined by measuring

with the liner applied.



Notes

Bony ML Dimension

From behind, at the level of the fold of the buttock, push the

body caliper upward with slight pressure until the medial, smaller,

angled arm of the caliper reaches the bony structure of the ischial

tuberosity.

The body caliper must be held so that it is exactly horizontal.

Exert slight pressure on the lateral caliper arm and read the

measurement.



Notes

Soft Tissue ML Dimension

Apply the body caliper at the precise height of the highest

proximal circumference measurement (30 mm below the ischial

tuberosity).

The body caliper must be held so that it is exactly horizontal.

Exert slight pressure on the soft tissues and read the

measurement.

Now you can begin designing the socket in the Otto Bock TF Design

application using the measurements you have taken.

Seminar TF Design - Functions 1

Notes

Introduction

When working on jobs in the Otto Bock TF Design software, you go

through up to four program stages, each of which has a tab in the TF

Design processing window:

Specification

Selection of the socket-specific data and entry of the patient

measurements.

Socket View

Three-dimensional view of the calculated prosthesis socket, with the

option to make corrections.

Component Selection Selection of components for the prosthesis.

Ordering Display and editing of the purchase order for the current job.



Notes

This is how you begin a Job in TF Design

Before you can create a transfemoral socket, you first have to

create the corresponding patient.

In the patient list of the Otto Bock Data Station, select the name

of the patient for whom you want to create a TF Design order.

Select the command New Job in the File menu, or use the New Job

button underneath the job list of the selected patient.

The Job Type tab is displayed. Select the dynamic button

Transfemoral.



Notes

At this stage, you can already decide which program

components of TF Design you wish to use.

You always have several options available to you for this

purpose.

Select the corresponding option fields.



Notes

If you want to create a prosthesis socket, select Socket Design. In the Specification tab which follows, you will be prompted to enter

the corresponding measurements.

If the socket already exists and you only require components,

choose Component Selection.

In this case, you have to classify your patient according to Otto Bock

MOBIS® in the Specification tab which follows and also enter the

length measurements required for free space calculation and

component selection.

If you are creating a prosthesis socket and then want to select

components to complete the prosthesis, select both Socket Design and Component Selection.



Notes

If you require a prosthesis socket, components, and an individual

foam cover, select all three options:

Socket Design, Component Selection, and

Custom cosmesis.

According to the selection, the measurements required for socket

design and component selection as well as additional circumference

measurements required for the custom cosmesis have to be entered

in the Specification tab that follows.

After you confirm your selection by clicking Next, the Specification tab

is opened in the TF Design processing window.

Enter all requested measurements here.



Notes

Specification

In the Specification tab, the measurements and details required by the

software are entered corresponding to the options you selected in the

previous tab.

Thus the number of measurements required is determined by your

selections.

Provide the following information in the left-hand column of the tab:

Order number

Socket

Liner

Valve

Degree of mobility

Patient weight

The buttons are initially displayed in red, and change to blue as

soon as a selection has been made. The specifications under the

first button Socket are mandatory in order to continue, while the

information under the buttons Liner and Valve is optional and

only entered when required.



Notes



Notes

In the right-hand column Measurements, select the patient’s

amputated side and enter a number of important patient measurements

used to calculate the socket, the prosthesis, and the individual foam

cover (if selected).



Notes

Entries in the Left-Hand Column

In the left-hand column, you pre-select a few core components of the

prosthesis socket. Thus you are influencing the design of the socket

and its 3D representation in the Socket View tab.

Furthermore, your patient can be classified here according to MOBIS®

(if Component Selection was chosen).

This determines which components from the Otto Bock product portfolio

are generally available for your patient in the component selection

process which follows, before the free space calculation is carried out.

Reference – identification of the current job.

Enter a reference or number for the job. This entry is later displayed

in the job list of the patient in order to identify the job data.

Provide additional information regarding the socket components

in the fields below.

Open and close these fields by clicking the corresponding

dynamic button.



Notes

Socket style and socket material Socket This is where you select the socket type, requirements, and

corresponding shaft material.



Notes

Liner If a liner is required, you can select the liner model, distal connection,

material, and liner size depending on the selected manufacturer.

Competitive products not included in the Otto Bock product

portfolio will not be considered on the order form.



Notes

Valve Specify the type of valve.



Notes

Mobility grade and weight

Mobility grade

Select the patient's mobility grade (grades 1 thru 4).

The selected mobility grade in conjunction with the patient weight has a

decisive influence on the functional characteristics of the prosthesis.

During the configuration of the prosthesis, only those components

which have structural and functional characteristics suitable for the

patient’s selected mobility gradeand weight will be displayed.

The mobility grades are defined as follows:

Mobility grade 1 – indoor walker

Mobility grade 2 – restricted outdoor walker

Mobility grade 3 – unrestricted outdoor walker

Mobility grade 4 – unrestricted outdoor walker with particularly high

demands

This classification corresponds to the generally applicable

profiling questionnaire of the Medizinischer Dienst der

Spitzenverbände der Krankenkassen e.V. (MDS) (German

Registered Association of Medical Services for the National



Notes

Health Insurance Companies).

During processing, you receive information about the selected

mobility grade by clicking on the mortarboard symbol.

Weight

Enter the patient weight. MOBIS® classifies patient weight to 75 kilograms/165 lbs, to 100 kilograms/220 lbs, to 125 kilograms/275 lbs and over 125 kilograms/275 lbs.

The patient weight combined with the selected mobility gradeis

displayed in the Otto Bock MOBIS® logo above the graphic with the

measurements.

Mobility grade 1 / patient weight <

100 kg/220 lbs

Mobility grade 4/ patient weight <

125 kg/275lbs



Notes

Mobility grade 1 – indoor walker

The patient has the ability or the potential to use the prosthesis for

transfer purposes at minimal speed on level floors. The amount of time

and the distance that he/she can walk are seriously limited due to

his/her condition.

Therapy goal: Restoration of the patient’s ability to stand and move both indoors and

with limited mobility outdoors.



Notes

Mobility grade 2 – restricted outdoor walker

The patient has the ability or the potential to use the prosthesis for

transfer purposes at minimal speed on level floors. The amount of time

and the distance that he/she can walk are seriously limited due to

his/her condition.

Therapy goal: Restoration of the ability to stand, walk and move both indoors and

outdoors without any limitations.



Notes

Mobility grade 3 – unrestricted outdoor walker

The patient has the ability or the potential to move with the prosthesis

with variable cadence and can simultaneously negotiate most

environmental barriers.

He/she also has the ability to move about open areas and can

undertake occupational, therapeutic and other activities that do not

expose the prosthesis to above-average mechanical demands.

This also includes those patients who have an increased need for

security due to secondary conditions (additional handicaps, special

living circumstances) in connection with medium to high mobility

activities. In comparison to healthy individuals, the amount of time and

the distance that he/she can walk are limited only in nonessential ways.





Notes

Mobility grade 4 – unrestricted outdoor walker with particularly high demands

The patient has the ability to move with the prosthesis in a manner

similar to the unrestricted outdoor walker. The amount of time and the

distance that he/she can walk are not limited. Moreover, due to the high

functional demands, the prosthesis can sustain a high degree of shock,

tension and torsion.





Notes

Entries in the Right-Hand Column (Measurements)

Side (left or right) – select the amputated side.

The input fields for the measurements are arranged on the correct side

of the graphic according to your selection.



Notes

Measurements of the amputated side

Residual limb length – length of the residual limb from ischial

tuberosity to distal end.

Socket length –length of the socket from position of ischial tuberosity

to distal end.

Distance measurements, originating from the ischial tuberosity

By default, three distance measurements are displayed in order to

mark the height of the circumference measurements. The proximal

measurement is specified 30 mm distally from the ischial tuberosity.

The distal measurement is calculated as soon as the residual limb

length has been entered; it is 50 mm proximally from the end of the

residual limb.



Notes

The position of the centre measurement can be freely selected and

should be positioned near the centre of the residual limb.

Limb circumference

Enter the measured residual limb circumferences at the respective

levels.

By clicking the More Values button, up to five circumference

measurements can be entered for the residual limb corresponding to

the distance measurements entered on the left.

If the Less Values button is selected, the standard setting with three

values is restored (30 mm below the ischial tuberosity, centre of the

residual limb, and 50 mm proximally from the end of the residual

limb).

Reduction of the circumference measurements in % or mm

Select the type of reduction for the respective circumference

measurements (percent or millimeters).

Each circumference measurement is reduced by either the selected

percentage (0-6) or the specified number of millimeters.

You can also change the measurements

graphically with the displayed slide control.



Notes

Socket – circumference measurements

Displays or permits direct entry of the reduced circumference

measurements.

The effective remaining circumference measurements after the

corresponding reduction are displayed here.

The reduction can also be undertaken or modified directly by

entering the target measurements in this column.



Notes

Measurements of the sound leg If you also chose Component Selection in the Job Type tab, the

measurements of the sound leg are also required.

Ischial tuberosity to floor

This measurement is used to determine the free space for the

prosthesis components after deducting the length of the residual

limb.



Notes

Medial tibial plateau to floor

This measurement plus 20 mm defines the vertical position of the

physiological knee rotation point. During virtual prosthesis design,

this position is also the desired ideal position of the alignment

reference point of the knee component (for monocentric joints, the

alignment reference point is the rotation axis; for polycentric joints, it

is the anterior upper axis).

Widest calf circumference

Defines the size of the – standard – foam cover.

Foot Measurements

Foot size (cm)

Effective heel height

This measurement affects the static structure of the prosthesis.



Notes

Other measurements If you have also selected custom cosmesis in the Job Type tab,

further measurements for the sound leg are also required.



Notes

Methods for entering socket circumference

The socket circumferences can be determined and entered using three

different methods:

Method A: Reduction in percent or millimeters

Method B: Direct entry of the reduced measurements

Method C: Manual reduction of the circumference measurements

After completing the Specification tab, switch to the next tab Socket View by clicking it with the mouse.



Notes

Entering the Measured Residual Limb Circumferences

Enter the circumference measured at the entry level (30 mm

below the ischial tuberosity) in millimeters. Maintaining a distance

of 30 mm from the ischial tuberosity is essential.

After entering the residual limb length (250 mm in this example), the

distance measurement 50 mm proximally from the end of the residual

limb is displayed automatically. The circumference measurement for

this position can now be entered.

An additional circumference measurement for the middle of the



Notes

residual limb must be entered at the corresponding distance from

the ischial tuberosity.

For very short residual limbs (90-120 mm) only the measurement

30 mm from the ischial tuberosity can be entered.

For very long residual limbs, it is also possible to enter additional

circumference measurements in the area between the initial

measurement (30 mm from the ischial tuberosity) and the end of

the residual limb (residual limb length - 50 mm).

You are free to choose the distances of the additional

circumference measurements from the ischial tuberosity, as long

as the distance between the measurements is at least 30 mm.

To do so, click the More Values button.

Two additional input fields for distance and circumference

measurements are displayed, so that a total of five circumference

measurements can be entered.



Notes

To reduce the number of measurement fields, click the Less Values

button.



Notes

Method A: Reduction in percent or millimeters

Determine the type of reduction in this column (percentage or

millimeters).

The corresponding reduction factor or value is selected and displayed in

the individual input fields.



Notes

You can also change the measurements

graphically with the displayed slide control.

Even reduction profile

If the lock symbol is closed, the reduction profile from the proximal to

the distal end is even; that is, all circumference measurements are

reduced proportionally according to the selected reduction. This is

indicated by equal reduction values for the initial measurement and

the measurement 50 mm distally from the end of the residual limb.

Uneven reduction profile

In order to create an uneven reduction profile, click the lock symbol

which is then displayed as ‘opened’.

Now the reduction can be individually selected for the two

measurements mentioned above.

The reductions for the circumference measurements between the

initial measurement and the measurement 50 mm above the end

of the residual limb are calculated based on the selected

reductions, the level of the circumference measurements, and

the resulting elevation of the profile segments.



Notes

Even reduction Uneven reduction

The socket circumference measurements calculated from the

residual limb measurements and reduction values are displayed in the

right-hand column.



Notes

Method B: Direct entry of the socket circumference measurements

If you do not wish to reduce the measurements further because of your

measurement technique or for other reasons, you can also enter them

directly in the right-hand column.

Alternatively, you can enter the distance and circumference

measurements as described under Method A but refrain from specifying

a reduction.

The values from the left-hand column are automatically transferred to

the right-hand column as target values for the socket circumference

measurements.



Notes

Method C: Manual reduction of the socket circumference measurements

Modifying the individual circumference measurements is also

possible through direct input into the right-hand column, for example if

you have calculated the reduction of the measured residual limb

dimensions yourself and do not want to use the reduction tool.

If you use this method, the values for the reduction in millimeters

or percent are not displayed.

Please note that if you select a reduction in percent or

millimeters, all manually modified values will be overwritten.



Notes

Socket View

In the Socket View tab, the socket calculated based on the data you

have entered is displayed in three dimensions.

You can view the socket from all sides and rotate it freely in space by

dragging it with the mouse.

When you first open the Socket View tab, three-dimensional

rotation is activated by default.

original values.




Notes

The adduction angle for the SIT Cast and ischium support socket types

is calculated as follows:

Ischial Containment:

The At the most distal height, the socket is divided at a 50-50 ratio in

the ML dimension. The distal end automatically orients itself so that

it is centred at the perpendicular line of the previously mentioned

ratio.

The adduction angle is then calculated as the angle of inclination of

the lateral socket wall to the verticalwall.

Adduction angle Flexion angle

Ischium support:

For ischium support sockets, the ML dimension proportion is 60-40

(medial-lateral). You can specify an adduction angle of 0º to 15º.

Notes

The sockets are designed with a default flexion angle of 5º. If no

other flexion angle is entered, the socket will be supplied with

this default.

You can specify a flexion angle of 0º to 15º.

The flexion angle is measured from the centre of the vertical

socket plumb line to the corresponding socket position.

shape accordingly. The socket length is not affected in this

process.

In addition to changing the shape using the slider control, you can set

the socket view into an anterior orientation.

In this best view, the adjustment is most clearly seen.

original values.




Notes

Display of socket dimensions

If you move the mouse cursor over the socket, an information field is

shown in the bottom right-hand corner of the screen. Here, the socket

dimensions are shown in at the respective cursor position.

Moving the cursor over the socket allows you to obtain the following

dimensions for the respective cursor position:

Distance to the ischial tuberosity (Z)

ML dimension

AP dimension

Socket circumference

Socket volume



Notes

Limb Statistics

With the Limb Statistics command in the View menu, it is possible to

compare the residual limb dimensions of two TF Design orders for a

patient. The following dimensions can be compared:

AP dimension

ML dimension

Circumference

Volume



Notes

After opening the residual limb statistics window, the left-hand side of

the window initially displays the values for the current job.

To compare these values with another job for the same patient,

you can select another job by date or reference in the selection

field at the top right.

The values for the comparative job are then displayed on the right-hand

side of the window.

Equalising the socket length

Prior to comparing two sets of measurements, it is necessary to

equalise the measured lengths to the same value so that a realistic

comparison is possible.

Differing length measurements result from unavoidable

measurement error in obtaining patient measurements.

Using a manual control it is possible to compare the volumes of

the two sets of measurements with comparable length.



Notes

Read the corresponding length of the residual limb from the

current values on the left-hand side and enter the same value in

the Length field on the right-hand side. The button Original Value located below displays the original residual limb length of

the second job and resets it when the button is clicked.

In the two Volume areas, you can compare the volumes of the two sets

of measurements.

Print outputs the data of the limb statistics to the connected standard

Windows printer.

Copy saves the data of the limb statistics to the Windows

clipboard. Use Ctrl+V to enter the data into another program,

such as a text processor, for further use.



Notes

Component Selection

In the Component Selection tab, TF Design guides you through all

phases of functional and constructive prosthesis configuration.

Since the initial calculation of the possible component combinations

demands a lot of computer processing power, you can monitor the

progress of this activity on the blue progress bar in the top of the

component selection tab.

The individual prosthesis components are then displayed for selection

based on the specified mobility grade and patient weight and the related

characteristics and criteria.

This configurator guides you through the component selection and

assembly process step by step, and continuously informs you about all

available options and the characteristics of the individual components.



Notes

The functions in the Component Selection tab are only

available if you chose the Component Selection option in the

Job Type tab.

After component selection is complete, you move to the Order tab.



Notes

Structure of the Component Selection Tab

The Component Selection tab is divided into three sections:

The Prosthesis section with a graphical, dimensioned

representation of the selected component.

The Component Selection section with the available components.

The Filter section assigned to the individual component selection

rows, which makes selection according to constructive

characteristics easier.



Notes

Prosthesis Section

In the Prosthesis section on the left-hand

side, you can see a graphical representation

of the assembled selected components.

This is where you see the current, still

incomplete or later also complete,

schematically assembled prosthesis.

The components you select in the Component Selection section are

inserted into this column.

The configured prosthesis is assembled graphically, step by step.

The purpose of the graphical information is to display the selection

process and to permit visual control of the components used.

As soon as the prosthesis is fully configured, the program automatically

calculates all measurements including free space.



Notes

The lower dimension of ± 0 shows that the selected

components fit into the available free space and that an

adjustment to the required overall prosthesis length is possible.

The upper value provides information regarding the position of

the alignment reference point (for monocentric joints, the

alignment reference point is the rotation axis; for polycentric

joints, it is the anterior upper axis).

The ideal position of the alignment reference point is assumed to

be 20 mm above the medial tibial plateau of the sound leg.

This is the case as soon as the upper value is ± 0 mm.

If the upper value deviates in the negative range, the alignment

reference point is too high up and vice versa.



Notes

Component Selection Section

In the Component Selection section in the centre, you select

the individual components - which are displayed graphically -

simply by clicking the illustration of the desired component.



Notes

The available components are displayed at the appropriate level of the

prosthesis schematic shown on the left-hand side.

The available components are divided into rows according to the

installation location within the prosthesis, from top to bottom:

Socket adapter

Upper component group

Prosthetic knee

Lower component group

Prosthetic foot

The individual components can be selected by clicking them with

the mouse, and are then inserted into the schematic

representation of the prosthesis shown on the left-hand side. If a

component from that group has already been inserted, it is

replaced and the new component is shown.

In order to display information about a component, hold the

mouse pointer over the component briefly. Descriptive text for the

respective component is displayed. Use these texts to help you

make decisions during component selection.



Notes

Components that are not compatible with previous selections or that are

not recommended for combination with previously selected components

by Otto Bock (comparison of knee / foot matrix) are identified with a red

X.

The program does not permit the combination of such components.

e.g.

If you select such a component that is identified with a red X, it is

still displayed in the schematic representation of the prosthesis

shown on the left-hand side.

At the same time, the previously selected component that is

incompatible with the new component is deselected and is itself shown

with a red X in order to identify that it is incompatible.

Components that do not fit into the available free space due to their

structural height in combination with the previously selected

components are displayed with an orange double arrow.



Notes

If you select such a component that is identified with an orange

double arrow, it is still displayed in the schematic representation

of the prosthesis shown on the left-hand side.

At the same time, the previously selected component that requires too

much space in combination with the new component is deselected and

is itself shown with an orange double arrow in order to identify the

space issue.

If more components are available than can be displayed in a row,

you can use the arrows on the sides to scroll left and right.

As soon as you complete a row by selecting a compatible component,

the colour of the corresponding filter changes from red to blue. A red

filter box indicates that a component selection has not yet been made

on the corresponding row.



Notes

Filter Section In the right-hand Filter section, characteristics for the individual

components can be selected. These characteristics correspond to the

characteristics or construction of the components.

When the Component Selection tab is first opened, no characteristics

are selected.

If there is a large range of choices in the type and construction of

a component, you can select the desired characteristics in the

filter section.

The components that correspond to the selected criteria are

automatically moved to the left side of the component row and identified

with green checkmarks.



Notes

The sequence of the components within a row is always

alphabetical and is not related to quality or price.

This also applies if the sequence was modified through the use

of filters. In this case, the selected components displayed at the

left are shown in alphabetical order within that sub-group.

You can identify the characteristics of a selected component at a

glance by looking at the small white dots within the

corresponding filter section. These show the assignment of the

component within the filter criteria.



Notes

Your work in the Component Selection tab is complete when:

You have selected a component from each of the five rows

according to your requirements.

The measurements are displayed in the schematic representation of

the prosthesis on the left-hand side and the values are acceptable to

you.

After component selection is complete, move to the Order tab by

clicking the corresponding button.

Ordering

In the Order tab, you can view a summary of the configured order as

well as summarized and detailed lists of all components.



Notes



Notes

The Order tab has an order list on the right-hand side, which includes a

description of the components.

You can set the quantity for each component in the order list.

If you do not need an individual component, you can deselect it

by changing the quantity to zero.

This allows you to avoid reordering components you may already

have in stock. On the other hand, you can order certain

components in larger quantities, for example to stock them as

replacement parts.

When an individual component of the prosthesis is selected in the order

list on the right-hand side, it is displayed with its product description

on the left-hand side of the tab.

This includes a photograph of the component and a specific description.
