We have been specialized in the equipping of the lower limb for a long time.

We have always sought to apply the new technologies presented in the world, and we have worked hard to develop or to enhance these new technologies such as:

In the area of the prosthesis:

• The 3S system
• Built-in ischium sockets
• custom liners in gel
• sealing rings
• automatic valves
• prostheses for specific sports with many results at Paralympic games
• working in partnership with Procosil and Dorset companies on cosmetic coatings
• etc …

In the field of orthotics, we master well prepreg. Most of our orthotics are produced with this method.

In addition, some of our employees have completed extensive training for the implementation of certain specific material such as BASKO (Proteor) joints, FREE WALK (Otto Bock) orthotics, jE-MAG (Otto Bock ) digitally programmed joints… etc..


As in the lower limb, we have extensive experience in the equipping of the upper limb, especially in cosmetic coating (in partnership with PROCOSIL), and in all functional prostheses.

Some of our employees have completed extensive training from different suppliers, enabling them to fully control the adaptation, adjustment, monitoring and maintainance of all the sophisticated products we offer to our patients.


Close to the sporting spirit and motivated to allow everyone to fulfill his or her desires, we design and manufacture many specific devices for sport: such as specially designed protheses for skiing, biking, running, tennis , climbing, diving … but also other technical aids on demand.

Lower limb prostheses are becoming more and more performant. This performance is due to the mastery of high-tech materials (carbon, silicone, polyurethane gel) and application techniques (even distribution of pressure, stability)

The orthotics have also become lighter, more efficient, better suited to sports (pre-impregnated carbon, elasticity, strength)

Athletic performance is directly related to the equipment:
Sport in question: the necessary amplitudes, functions required, etc …
The level of amputation or disability: can lacking or insufficient functions be compensated for by an appliance?
The equipment or technical solutions available to us
The former practice of sport: you do not become a sportsperson because you are equipped with a prosthesis

Before considering an appliance:
In all cases it is necessary to make a thorough study of the effect of the disability on the sport concerned to find the optimal functional solution.
Before doing anything study the cinematics of the sport and clearly identify the required specifications

There are two types of sports prostheses :
Prostheses designed for everyday life with advanced socket systems and high-technology prosthetic components.
Specific sports prostheses for performance without compromise.

Corset seats

The seat brace is a registered anatomical installation recommended for maintaining prolonged sitting in people withsevere static deficiency of neurological , muscular or genetic origin.

With good stability in the sitting position and a support of the spine, the seat brace has a preventive role on orthopedic deformities and prevents the formation of bedsores. This equipment also allows the user to regain a social and family life by enabling life in the community.

The corset is customized for each patient with a large number of possible additions, such as:

An adjustable headrest
A rolling Stand
abduction hold
etc …
Before implementation, the orthotist conducts a study of optimal positioning and an analysis of the needs of each patient, with medical and para-medical staff and all relevent parties.

It is made of molded thermoformable materials, combined with a thermoformed foam, injected or milled, ensuring comfort


They are apparatus for placing in an upright position non-walking children .

These orthesis are in the form a thermoformed shells from a positive plaster mould. According to the pathology to be treated they may be:

or posterior.

Some extensions arranged at the hips and ankles enable it to follow the growth of the patient.

Many accessories are available to facilitate the development of the child and ensure his/her continued good position.


We manufacture helmets through molding in cases of cranioplasty, before the reconstruction of the area of the skull removed.


All corsets are manufactured after scanning the patient in the appropriate position

This scan can also be achieved while lying down

For scan correction we use Rodin 4D software


Operating principle

Myoelectric prostheses operates using  the controlled muscle contractions of the patient.

Electrodes placed in contact with the skin pick up muscle signals that are sent to a motor placed in the hand. The engine goes into action with the energy supplied by a battery, thereby triggering the opening and closing of the hand.

For the optimum operation of the prosthesis, the choice of electrode placement is critical.

We use the MyoBoy tester to visualize on a computer screen a representation of the muscle contractions, but also to simulate the different types of myoelectric hands.

We can thus validate the point where the muscle is most effective to activate the operation of the hand: the motor point.

In some cases, the muscle impulse is too weak or nonexistent, the trigger level to operate a prosthesis will not be reached.

The tester is also used in rehabilitation centers for training of patients in order to gain better control of the hand.

The prosthetic forearm  socket is based on the same principles as for fixing a conventional prosthesis: a sub-epicondylar clip, it is the same for prosthetic arms that are held by a strap-harness.


We offer cosmetic silicone prostheses with customised colouring.

This type of prosthesis can be made for several kinds of amputation:

  • The hand
  • Partial hand

For partial or total amputations of hands to the finger joint  with a flexion of approximately 90 degrees to accommodate specific activities (eg typing …) may be added

  • Finger (s)

We can also offer these kinds of manufacturing for prosthetic forearm and arm.

A transparent silicone base is found to be in choice of shapes, its created from the cast of the opposing limb (in the second case we obtain an exact replica).

This form of hand or transparent finger is then painted as closely as possible to the particularities of skin colour.

Despite the care we provide at this stage, the colour stays the same unlike the colour of the skin that varies throughout the day and according to exposure to the Sun .
The nails are also customized (in shape, in colour, and in length), they are made of resin and can be varnished.


Principles of operation
Prosthesis comprising a hand or various interchangeable tools. The activation of hand
movement or grip is achieved through a system of wiring connected to the opposite shoulder.

The articulated hand is covered with a PVC glove.

Many tools and adaptations are available each tailored to a specific activity.

The arm prosthetic can be manufactured with or without the elbow. Depending on the
elbow the locking is done either manually (pushing a button activated by the opposite hand)
or through a cable system connected to the opposite shoulder.

Types of attachment
The means of fastening the socket onto the stump depends on the choice of terminal tools .
Refer to section  » means of fixing aesthetic prostheses »



Trying to compensate for motor deficits that affect the brachial plexus, in order to exploit the remaining motor function.

Method of manufacture

These braces are made from carbon or polyethylene.
Their helical shape facilitates their fitment.
Their weight will always be the lowest possible.

They may, if necessary, be joined to the shoulder , without wearing a scarf.


A tibial socket should satisfy the following principles for comfort, safety, dynamism

• Distribution of support
• Volume management
• Fixing and fitting

Different techniques are proposed based on the characteristics of the stump, the patient, and the objectives to reach.

The socket called « contact » (without shorts or straps) developed around the sixties, has continued to improve thanks to the arrival of new materials such as resins, foams, thermoforming, silicones, and gels. These materials have given birth to advanced manufacturing techniques, with the use of prefabricated liners with polyurethane gel or silicone in thick copolymer , up to the use of liners made of silicone in a molding workshop that satisfy the most dynamic of patients as well as sportsmen and women (socket « 3S »).


The prosthesis for femoral amputation consists of a socket that receives the stump of a prosthetic knee and a foot.

The importance of the socket is predominant in the quality of the prosthesis. It is that which will determine the use of the device.

Indeed, it must have the qualities necessary to provide:

There are many types of sockets characterized by their principle of suspension, their shape and the materials used.


Low amputations of lower limbs: tibio-tarsal, trans-tarsal and midtarsal always pose a problem of length compared to the healthy limb.

In addition, we will be impeded by the shape of the stump (wider distally than the rest of the stump) to achieve the most aesthetic prosthesis possible.

We can manufacture different prostheses for partial foot amputations, according to the patient’s requirements.


The so called Canadain Prostheses

The traditional socket consists of:

A carbon semi-hull.
A belt made of resin, polyethylene or moulded leather.
The attachment of the socket will be made on each side above the iliac crest: the « clip-size »
A polyethylene foam or gel pad is included in the carbon semi-body at the seat to increase comfort.
An attachment to the anterior internal ischium and branch is possible to optimize control.

The shapes of the shells can be varied depending on the patient’s needs.


We have extensive experience in making prosthetics for agenesis.

In this type of appliance, our aim is to obtain:

comfort and aesthetics in the first place;
dynamism to the greatest extent possible.
Prostheses for femoral agenesis are manufactured with the principle of sockets with integrated ischium (see description of the neck socket femoral prostheses). This principle allows us to minimize the flexion contracture.of the knee

Here are some examples of our achievements …

Ortheses for legs

Orthotics are devices designed to correct a deficient function, to compensate for a disability or improve the physiological capacity of a limb.

Orthotics are customized and come in many forms as the choice in terms of articulations and combinations of materials is large.

Our orthotics are made specifically according to the desired effect (correction, keeping the patient’s requirements …) to look for maximum functionalitywith minimum encumberment .
