Notes
The Three-Dimensional Socket Model
After processing the digital pictures, the TT Design application
calculates the socket shape using a “morphing” algorithm.
This algorithm adjusts the chosen reference socket model to the
calibrated residual limb contours obtained from the digital photos. It
changes and reshapes the reference socket model until it matches the
contours shown in the digital photo.
#1 to be replaced
The illustrations below show how the reference model “grows” into the
correct contour during the morphing process. The result is an actual
socket model and not simply a reconstruction of the residual limb.

Tools
When working with the Otto Bock TT Design application, you require
the following tools:
1 Body caliper to measure the residual limb (743S20)
2 Calibration piece for digital photography (743S30)
3 Residual limb sock 2-pack (99B90=2)
4 Digital camera (743L234)
5 Black background (743S50)
6 Knee angle check (743S40)
7 Velcro patches to attach the Calibration piece (623Z20)
Lesson Error! Style not defined.
Seminar Otto Bock Data Station – Measuring 8
Notes
Working with the Patient
Seat the patient on the black background so that the entire residual limb
being photographed is located in front of the black background.
Obtain an impression of the soft tissues and bony regions of the
residual limb by palpating it.
Put the white residual limb sock onto the patient so that there
are no distal folds.
The TT Design kit includes a residual limb sock for all residual
limb sizes. This is the only type of sock that can be used for this
process. Please do not pull the sock up too tight, since this can
affect the residual limb shape.
Lesson Error! Style not defined.
Seminar Otto Bock Data Station – Measuring 9
Notes
Palpating the Residual Limb and Recording the Residual Limb Measurements
Measuring and marking the residual limb prepares the patient for digital
photography.
The following points are marked:
Centre of the patella ligament
Height of the medial condyle and soft tissue condyle
measurement (depending on the socket model)
Initials of the patient
The fibula head and any other important features of the residual
limb (end of the tibia, scars, problem areas)
Lesson Error! Style not defined.
Seminar Otto Bock Data Station – Measuring 10
Notes
Use the body caliper, which has a slot in each caliper arm, to
mark the centre of the patella ligament.
To do so, press the upper caliper arm between the lower edge
of the patella and the tibial tuberosity and mark the centre of the
patella bar. This method is easy to reproduce. Laterally elongate the
line slightly so that the centre of the patella ligament can also be
seen on the lateral photo.
Attention
Correctly marking the centre of the patella ligament is crucial for
the correct socket length.
To create a trans-condylar socket, mark the medial condyle
height and measure the soft tissue condyle dimension.
Move the body caliper proximally starting from the centre of the
knee and bring the caliper arms together to determine the lowest
point of the condyle socket; mark it laterally through the slot.
In this position, read the soft tissue condyle measurement from
the body caliper and note this value on the patella. It is then recorded
on the photo and is available for socket production.
Marking the condyle height establishes the lowest point of the
condyle socket, not the height of the socket edge.
Lesson Error! Style not defined.
Seminar Otto Bock Data Station – Measuring 11
Notes
Write the patient’s initials and the soft tissue condoyle
measurement onto the patella.
For PTB sockets, mark the height of the socket edge at the
medial tibial plateau. A soft tissue condyle measurement is not
required in this case.
Mark the fibula head and any other important features of the
residual limb that could lead to pressure points and therefore have to
be considered when creating the socket model onto the sock. Also,
mark the highest point of the elevated area (patch) with a cross.
Creating the Digital Photos of the Residual Limb
Two digital photographs of the residual limb are required as the basis
for calculating the three-dimensional socket model in the TT Design
application:
The anterior view
Lesson Error! Style not defined.
Seminar Otto Bock Data Station – Measuring 12
Notes
The lateral view
The Calibration piece, the black background, and of course the digital
camera are required for this purpose.
Consider the following during photography:
Use the black background in order to create a good contrast
relative to the residual limb. On the photo, the entire white residual
limb sock must be underlain with the black background.
Lesson Error! Style not defined.
Seminar Otto Bock Data Station – Measuring 13
Notes
Ensure that the background is not pressed against the residual
limb, since this affects the shape or the residual limb contour on
the photo.
Check the knee flexion angle of the seated patient with the
supplied knee angle (15°).
Check the seating position of the patient. The amputated side is
frequently stretched forward, which causes interior rotation of the
residual limb. When taking the digital photos, the spinae should
be parallel to the back of the chair.
The residual limb must be photographed at maximum optical zoom (3x).
Ensure that the distance is approximately 1m. This is normally
the case when the residual limb fills picture in the viewfinder at
maximum zoom.
Use the Velcro patches to attach the Calibration piece along
the tibial crest. The Calibration piece helps to position the camera
and to calibrate the residual limb measurements.
Ensure that the Calibration piece is not tilted laterally or medially
when it is attached. The proximal or distal position is not
significant. The Calibration piece must be fully visible on the
Lesson Error! Style not defined.
Seminar Otto Bock Data Station – Measuring 14
Notes
photo.
Correct Use of the Calibration piece
The fins of the Calibration piece help you find the correct
camera position for anterior and lateral photos.
The reflector points are used to calibrate the software as a
reference measurement used to determine the residual limb
dimensions.
Here is how you determine the correct camera position for anterior and
lateral photos with the help of the Calibration piece:
Only the edges of the fins on the Calibration piece must be
visible.
Lesson Error! Style not defined.
Seminar Otto Bock Data Station – Measuring 15
Notes
Two reflection points on the Calibration piece must be visible. If
more than two reflection points are visible, you are not positioned
orthogonally to the Calibration piece / residual limb.
Place yourself at a distance from the patient so that the residual
limb up to the mark on the condyle socket fills the image at maximum
zoom.
However, a minimum distance of 1 m must be maintained.
To be replaced
Use of the Portrait and Landscape Format
When creating the digital photographs, ensure that the residual limb fills
the image.
Lesson Error! Style not defined.
Seminar Otto Bock Data Station – Measuring 16
Notes
Use the portrait format for the anterior photo.
Use the landscape format for the lateral photo.
The illustration below shows a correct lateral photo in landscape format,

Remove protrusions
If irregularities in the residual limb contour were photographed along
with the residual limb (e.g. folds in the residual limb sock), so-called
protrusions can result during the automatic residual limb contour
calculation process.
You can correct such irregularities with the Remove protrusions
tool.
To do so, drag the connection between two points until it is smooth,
thus removing the protrusion.
To increase the size of the photo view, use the Zoom plus tool.
Click the point on one side of the protrusion.
Now press and hold the SHIFT key and drag from the starting point
to the end point on the other side of the protrusion while holding the
mouse button. As soon as you release the mouse button, all points
between the start point and the end point are deleted.

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 grade and weight will be displayed.
The possible 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

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.
Lesson Error! Style not defined.
Seminar Otto Bock Data Station - Functions 19
Notes
Mobility grade 2 – Restricted outdoor walker
The patient has the ability or the potential to move slowly with the
prosthesis and can negotiate low environmental obstacles like curbs,
single steps or uneven ground. The amount of time and the distance
that he/she can walk are 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.

During this process, you always mark a single point on the photo using
the mouse. The illustration below saves your positioning in the anterior
view.
First, mark the distal end of the calibration tool.
The mark KSD is entered. The mark must be placed as close to
the centre of the distal white point of the calibration tool as
possible, since the calibration tool serves as a reference point for
calculating the socket dimensions. You can also use the zoom

socket. The orientation calculated by the software is displayed.
You can correct the orientation of the condyle socket by clicking
the end of the displayed fork and rotating it correspondingly while
holding down the mouse button.
The axis with the condyle angle displays the orientation.
This orientation ensures that the condyle socket generated by the
reference model corresponds to the actual patient contours.
A proven method is to orient the condyle socket so that the
lateral shanks of the fork follow the lateral condyle as in the
illustration.
In order to get a feel for this tool at the outset, it may be useful to
switch back to the photo processing tab from the socket model
generated later, modify the position of the fork, and recalculate
the socket. Thus the effects quickly become obvious.

Notes
Contour recognition threshold With this tool, you can set the brightness level the software uses to
differentiate the pixels in the digital photo as the residual limb or
background. The setting is established using a slide control.
With Use Default Value, you can reset this setting to the default value.
The lower this value is set, the further the contour extends outwards,
since darker pixels are now also identified as part of the residual limb in
the transitional area between the residual limb and the background.
This function can be useful for underexposed photos. If the value
is set too low, a black line is visible between the residual limb
and the calculated contour; this effectively makes the socket
bigger. Errors where parts of the background or the calibration
tool are identified as part of the residual limb are also more
frequent in this case. These protrusions have to be removed with
the help of the contour editing tools.
The higher this value is set, the less far the contour extends outwards,
since lighter pixels in the transitional area between the residual limb and
the background are located closer to the centre of the residual limb.
Lesson Error! Style not defined.
Seminar Otto Bock Data Station - Functions 46
Notes
For overexposed photos, raising the brightness level can be useful.
If the value is set too high, the contour recognized by the program is
located within the residual limb. In this case, the contour is frequently
very irregular and does not follow the shape of the residual limb.
Medial support After displaying and optionally editing the anterior contour of the
residual limb, you can establish the position and thickness of the medial
support using the mouse.
To increase the size of the photo view, use the Zoom plus tool.
To do so, drag the line with the three symbolic double arrows to
the desired position.

moved.
By opening the dynamic button Medial Support, you can
establish the thickness of the support. The default value is 3 mm.
Adding patches
While editing the image in the Photo View tab, you can insert one or
more so-called patches in the anterior and lateral views; patches are
applied to the socket model at the location of bony protrusions or scars.
This affects the most prominent point of the area being built up or

Residual limb statistics
With the Residual Limb Statistics command in the View menu, it is
possible to compare the residual limb dimensions of two TT Design
orders for a patient. The following dimensions can be compared:
AP dimension
ML dimension
Circumference
Volume
Lesson Error! Style not defined.
Seminar Otto Bock Data Station - Functions 67
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.
Reconciling the residual limb length Before comparing the residual limb dimensions of two orders for a
patient, the residual limb length must first be reconciled to the same
value so that a realistic comparison is possible.
Differences in the length measurements are unavoidable due to
small discrepancies when the positioning the MPT (‘Mid Patella
Tendon’) mark.
The volume of the two residual limbs can only be compared if the
residual limb lengths are reconciled manually.

Seminar Otto Bock Data Station - Functions 68
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.
You can view the volumes of the two residual limbs in the Volume
fields.
With Print, you can send the residual limb statistics data to the
connected Windows printer.
With Copy, you can store the residual limb statistics data on the
Windows clipboard.
With Ctrl+V, you can paste these data into another program, e.g.
a word processor, for further editing.

Component Selection
In the Component Selection tab, TT 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 degree of mobility 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.

Structure of the Component Selection tab
The Component Selection tab is divided into three vertical 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 graphical information shows the progress of the selection process
and permits visual verification of the components used.
As soon as the prosthesis is fully configured, the program calculates the
free space.
A 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.

Seminar Otto Bock Data Station - Functions 73
Notes
In the Component Selection section in the center, you select
the individual components - which are displayed graphically -
simply by clicking the illustration of the desired component.
The available components are displayed at the appropriate level of the
prosthesis schematic shown on the left-hand side.
Lesson Error! Style not defined.
Seminar Otto Bock Data Station - Functions 74
Notes
The available components are divided into rows according to the
installation location within the prosthesis, from top to bottom:
Socket adapters
Component assemblies
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.

Seminar Otto Bock Data Station - Functions 75
Notes
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 a double arrow. This applies to
component combinations that are too long as well as those that are too
short.
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.

Notes
As soon as you complete a row by selecting a compatible component,
the color 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.
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.

Seminar Otto Bock Data Station - Functions 77
Notes
The components that correspond to the selected criteria are
automatically moved to the left side of the component row and identified
with green checkmarks.
The sequence of the components within a row is determined by
the MOBIS® system; the components are listed in ascending
order by the degree of mobility and allowable patient weight (see
Otto Bock System Overview for Modular Leg Prostheses in the
catalogue).
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 the corresponding MOBIS sequence within that
sub-group.
You can identify the characteristics of a selected component at a

corresponding filter section. These show the assignment of the
component within the filter criteria.
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

Order
In the Order tab, you can view a summary of the configured order as
well as summarized and detailed lists of all components.
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.

Notes
The Order tab contains the order list on the right-hand side, which lists
the item numbers, descriptions, and order quantities.
You can set the quantity for each component in the order list.
If you do not need an individual component, you an 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.
