A Case Report on Enhancing the Dexterity of Finger Prostheses Through the Use of a 3D-Printed Joint Emulator

After a traumatic amputation, losing all or part of a finger can be detrimental to one's physical and mental health. Benefits from an esthetically pleasing prosthesis might be psychological, practical, and restorative. Prerequisites for an optimal finger prosthesis include helping the user grasp, absorb, and transfer forces to the hand; the prosthesis should also seem natural and allow for gesture expression. This case study describes how a 3D-printed joint emulator simulates natural joint mobility, significantly enhancing the patient's functional capacity to perform fundamental everyday tasks.
