New 3D Printed Wrist Orthosis

In order to offer a new product improving the healing and/or rehabilitation of injuries or injuries to the wrist and hand, Médicus is seeking to develop a new orthosis for the wrist and hand by 3D printing. This project will focus on the development of an orthosis related to carpal tunnel syndrome as well as droopy hand. Among the issues to be addressed in this development proposal, the investigators find: 1) Identification of the best methodology for taking digital impressions; design of an orthosis with the following characteristics: (i) no external attachment system, (ii) spiral design with a thumb ring, (iii) manufacturing by 3D printing and (iv) a cost of less than $150 ;3) Performing technical and clinical trials.
