2 Description of the Design and Individual Components
Your prosthesis mainly consists of a custom pelvic socket to embed your residual limb, the hip
joint, the knee joint, connection adapters and the prosthetic foot. The exterior appearance may be
formed by a cosmetic foam cover. The static alignment has been adapted to your individual needs
and takes the heel height of your shoe into account.
A consistently good fit of the pelvic socket of your prosthesis can only be maintained if your pelvic
circumference and volume remain constant. The adjustment range offered by adjusting the clos
ure straps is limited. Further information is found under volume fluctuations in Section 4 "Medical
and Therapeutic Aspects".
In accordance with your indications and personal requirements, you have received a prosthesis of
the following design:
Pelvic socket: In your case, the connection between the body and the prosthesis is provided by
a plastic pelvic socket that opens in the front. The Ottobock team has selected the socket design
and material combination best suited to you and your specific needs. The seat of your pelvic sock
et was designed to accommodate your individual physical characteristics. The seat padding
materials also facilitate weight distribution. The socket firmly encloses the pelvis and encom
passes the iliac crests in order to attach the prosthesis to the body. This tight fit is required to
enable the transmission of movements from the pelvis to the pelvic socket and thus to the pros
thesis.
Prosthesis components: Different hip joints, knee joints and prosthetic feet are available for a
hip disarticulation prosthesis. The Ottobock team has selected the prosthetic components best
suited for you, adapted them to your mobility grade and adjusted them to comply with your indi
vidual requirements.
3 Areas of Application and Usage Restrictions
Your prosthesis serves as a functional and cosmetic replacement for the amputated limb and
enables you to sit, stand, and walk.
The use of your prosthesis and the performance you will be able to achieve depends on your indi
vidual diagnosis, the residual limb conditions and your mobility grade. Please consult your doctor
regarding the daily duration of use and potential therapeutic measures (e.g. occupational therapy
or physical therapy) to improve your performance.
In general, you should not experience too much discomfort when wearing your prosthesis.
Excessive pressure can lead to complications.
4 Medical and Therapeutic Aspects
As a general rule, targeted physiotherapy is recommended in order to maintain and improve the
functionality of the disarticulation region.

5
Please discuss all measures for maintaining and improving residual limb functionality as well as
the treatment and hygiene of the disarticulation region with your doctor. Depending on your spe
cific indications, complications can occur in individual cases. This may restrict your ability to wear
the prosthesis.
Treatment and Hygiene of the Disarticulation Region
Caring for the skin in the disarticulation region on a daily basis is very important. Washing the dis
articulation region daily with skin-friendly soap can prevent skin problems. Use special care
products such as Derma Prevent, Derma Repair and Derma Clean.
Volume Fluctuations
As a prosthesis wearer, you should pay special attention to your weight since any fluctuations will
have a direct impact on the fit of your prosthesis. Minor volume fluctuations over the course of the
day are normal.
If you have additional questions regarding volume fluctuations, please consult your doctor or
prosthetist.

6 Handling
6.1 Shoe Selection
CAUTION
Incorrect effective heel height
Falling injuries due to loss of functionality
►When buying new shoes, be sure to observe the predetermined effective heel height.
Effective Heel Height
The effective heel height of the prosthesis is determined during the construction of the prosthesis.
The heel height of the prosthesis cannot be altered and is calculated by the heel height minus the
forefoot height.
Calculation of the effective heel height:
The effective heel height (a-b) of your pros
thesis is:
……..
Do not use your prosthesis without a shoe that correctly balances the heel height of the prosthetic
foot. Otherwise, extension loading of your knee joint and a risk of slipping may result.
6.2 Check
CAUTION
Use of a worn or damaged prosthesis
Restricted support or injuries due to changes in or loss of functionality
►Before each use, check the prosthesis for functional reliability and for possible wear or dam
age.
►If the prosthesis or a component of the prosthesis shows any signs of wear (e.g. tears,
deformations, poor fit) or damage, the prosthesis should no longer be used.
CAUTION
Volume fluctuations of the affected limb or problems with the fit (e.g. caused by growth)
Injuries, friction, pressure sores, circulatory disorders and paralytic symptoms caused by prob
lems with the fit
►If the product is fitted during the growing phase, it must be adjusted according to changing
body dimensions.
►Check the skin daily for damage and sensitivity disturbances (visually and by palpitating).
►Please consult your doctor or prosthetist in case of any signs of skin damage, even if they
are only minor.
Please verify that your prosthesis is undamaged and functional prior to each use.
Every time you put on your prosthesis, verify that the prosthesis is firmly in place by pulling on it.
First-time users in particular have to learn how to handle the prosthesis. Donning and doffing, sit
ting, standing, and walking, as well as possible falling must be practised. Your doctor, physio
therapist or prosthetist can provide you with additional advice on prosthesis training.
Special attention was paid to the materials used for your prosthesis. They were tested for skin tol
erance. If skin changes develop in your disarticulation region, please consult your doctor in a
timely manner.

6.3 Donning the Prosthesis
Your Ottobock team instructed you in how to don the prosthesis. The following donning tech
nique is well proven:
1) Make preparations such as putting on trousers and the shoe while seated.
2) It is best to stand up in order to don the prosthesis.
3) Open the pelvic socket just wide enough to enter with the amputated side.
4) Smooth your underwear or residual limb sock to avoid wrinkles and thus prevent pressure
sores and chafing.
5) Tighten the closure straps one after the other. Ensure that your skin does not get pinched.
6) Lift the prosthesis with your body as if you were taking a step.
→This allows you to verify that the pelvic socket is positioned correctly. It must not slip or con
fine the body.
Remove the prosthesis if it does not fit properly. Try donning the prosthesis again. Contact your
prosthetist in case of any problems.
6.4 Wearing of the Prosthesis
WARNING
Operation of motor vehicles
Risk of accidents due to restricted body function
►Observe the applicable legal and insurance regulations for the operation of motor vehicles
and have your driving ability examined and certified by an authorised agency.
CAUTION
Excessive strain on load-bearing components
Injuries due to breakage of load-bearing components
►Sports activities are only permitted after consultation with your doctor or prosthetist/orthot
ist.
►If the product has been exposed to extreme strain (e.g. due to falling), take any necessary
measures (e.g. repair, replacement, inspection by the manufacturer's customer service
etc.).
An energy-saving and natural gait requires a functional prosthesis. Please consult your prosthetist
if you experience any problems despite correct handling.
6.5 Doffing of the Prosthesis
1) Release the closure straps.
2) Open the pelvic socket and slide the amputated side out of the prosthesis.
7 Cleaning and Care
CAUTION
Use of unsuitable cleaning agents or disinfectants
Impairment of functionality and damage due to incorrect cleaning agents or disinfectants
►Only clean the product with the approved cleaning agents.
►Only disinfect the product with the approved disinfectants.
►Observe the instructions for cleaning and care.
Your prosthesis, especially the interior of the pelvic socket, requires regular cleaning.
Prosthesis
Cleaning with a damp cloth will generally be sufficient. Ottobock recommends Derma Clean to
disinfect the prosthesis. Clean any plastic surfaces with water and skin-friendly soap. Dry the
cleaned areas thoroughly. Do not place the prosthesis on a radiator or other heat source. Ensure

8
that no soap residue is left on the prosthesis, since this could cause skin irritation in the disarticu
lation region.
Please consult your doctor if you have any questions on skin diseases or disinfection methods.
8 Maintenance
CAUTION
Lack of or insufficient maintenance
Injuries due to changes in or loss of functionality
►Observe the specified maintenance intervals.
