Project news
March 2021

After Reuters a month ago, it was the turn of the AFP to meet our teams in Gaza a few days ago. The journalists from the press agency were able to visit the hospital, meet patients from the 3D program and discover the technological innovations implemented by the Foundation thanks to the support of our partner Rodin4D. This AFP report was picked up by many media, with a story on TV5MONDE but also in La Marseillaise, L'Est Républicain or L'Orient-Le Jour.

 

February 2021

As the project continues to develop in the field, the international news agency Reuters visited the MSF teams in Gaza. This was a good opportunity to present the progress of the 3D activities on site and to highlight once again the exceptional work of the physiotherapists and physiotherapists of Médecins Sans Frontières (MSF) France, who are making it possible for this project to continue. The telemedicine support provided by our team continues to play a key role in the development of this innovative practice.

A solution to equip a larger number of patients with prosthetics

Since 2016, the Fondation Médecins Sans Frontières has been betting on 3D technology to try to overcome the problem of access to prostheses in our intervention contexts. This is a major challenge for amputees to regain their physical integrity and autonomy. The project team in Amman, Jordan, has proven since June 2017 that 3D printing of prostheses is a tool adapted to the field, more personalized and adapted to the needs of patients and less expensive than the traditional method of manufacturing prostheses.

The project has also expanded to design facial compression masks for burn patients, in Amman since 2018 but also in Haiti in 2019 and in 2020 in Gaza, also using 3D technology. Facial burns can lead, months after the accident, to very serious after-effects if they are not treated with compressive masks and a thorough follow-up of the patient. The method of making these masks assisted by 3D technology is less painful, more comfortable for the patient than the traditional technique and allows for expert-assisted treatment at a distance, thus increasing access.

These two facets of the project are possible thanks to the use of scanners that allow the digitization of data that can be sent to experts in specialized centers so that they can share their knowledge and know-how. This digitization makes it possible to overcome the main barrier to access to care: the involvement of personnel trained in these very specific tasks. Tele-expertise is therefore taking a leading role in the Foundation's 3D projects.

The six key steps in the design of 3D prosthetics:

° 1 An individualised clinical assessment is made is made to determine the patient’s needs and expectations.

° 2 The scanner is used to make a 3D image of the surface of the stump.

° 3 Modelling software is used to design the socket* and the prosthetic.

° 4 3D printing is carried out by superimposing layers of plastic or other material.

° 5 Tests are carried out to check the fitting of the prosthetic and make any modifications required.

° 6 A follow-up and evaluation of the effectiveness of the prosthesis and its benefits is carried out for several months.

* Socket: interface between the patient’s stump and the prosthetic.

 

The six key steps in the design of facial compression masks:

° 1 An individualized clinical assessment is performed to determine the patient's needs and expectations.

° 2 The scanner is used to make a 3D image of the patient's face.

° 3 The digitized file is sent to a center specialized in the treatment of burns in France at the Léon Bérard Hospital in Hyères or to our teams to be reworked and thus shape the mold of the compression mask.

° 4 The file is sent back to the field. The mold is printed in a center equipped with a 3D printer to cast a plaster on which the glycolized polyester sheet (PETG) will be applied, which will constitute the final mask.

5 Tests are performed to verify the fit of the orthosis and make modifications.

6 Follow-up and evaluation of the mask's effectiveness and the patient's progress are then performed over several months.

Project history
July 2019
At Drouillard Hospital in Port-au-Prince (Haiti), MSF manages the structure for severe burns victims.
It was therefore quite natural for the manufacturing of face masks for facial burns victims to be launched there.
June 2018
A second section of the project starts in Amman (Jordan):
In addition to 3D-printed upper limb prosthetics, the Foundation uses the same technology to launch the manufacturing of compression masks for facial burns victims.
Why 3D-printed masks? The conventional mask-making method consists in applying strips of plaster on the patient’s face. This step, which is cumbersome, uncomfortable and sometimes traumatising for the patient, is thus avoided thanks to 3D scanning and rapid printing of the transparent mask.
December 2017
Over the first six months of the "3D prosthetics" project, 17 patients were equipped at Amman Hospital (Jordan).
Ten children and seven adults thus regained mobility and therefore an improved social life.
Mai 2017
The project team tests various modelling and 3D printing software.
In close collaboration with patients, it endeavours in particular to compare “conventional” sockets and sockets which it prints in 3D at the Irbid FabLab.

Keywords
//  3D printing
3D printing is a process for manufacturing parts by stacking of successive layers. 3D printing enables an object to be produced after it has been modelled on computer.
In our project, the operator first makes a “3D scan” of the patient’s morphology which is subsequently processed on computer, and then the prosthetic or the face mask is printed in 3D to fit the patient optimally.
//  Socket
In a prosthetic, the socket is the part designed to accommodate the stump. The quality of its design and its production is therefore extremely important for the functional result: it must be comfortable and easy to put on and fit securely on the stump.
//  Active prosthetic
An active prosthetic is a prosthetic adapted to patients who need a grip to hold objects for example. This particularly concerns patients who are affected on both sides.
A passive prosthesis is a fixed prosthesis adapted to unilateral patients, who still have a functional hand that they can use to carry out all or most of the activities of daily living.
//  Compression mask
A compression mask is used to accompany the healing of patients with burnt face . Applying a compression mask to the patient's face reduces post-operative effects, facilitates healing and shortens healing time.
