Producing temporary hand prosthetics for amputated digits using 3D technology: A multi-case study

Abstract

Recently, a new method has been devised for making temporary hand prostheses for amputated fingers using 3D technology. This report aimed to verify the fabrication method through comparing its practicality with a temporary training prosthesis made from thermoplastic resin. Subjects were 5 amputees of fingers who had previously completed treatment of an early prosthesis fitting method. The Simple Test for Evaluating Hand Function was performed by making the subjects wear temporary hand training prosthetics made with a 3D printer. The results indicated little difference in practicality between the two methods, but it was found to be necessary to change the work procedure to improve the decorative surface of the temporary hand prosthesis made with the 3D printer. Furthermore, a 3D printer is advantageous due to its limited burden on the patient. However, the disadvantage is the need to take measures in terms of maintaining and improving finger strength.
