Introduction
Finger amputations are the most common work-related amputation in Korea. Even through amputated fingers can be functional when more than half of the proximal phalanx is preserved, it has negative impacts of the patient's hand function, quality of life, and self-esteem. Recently, 3D-printed prostheses has been gaining attention in various levels of upper limb amputation due to its low cost, onsite fabrication, and easy customization. In this study, we reports two cases of work-related finger amputation patients who received body-powered, 3D-printed finger prostheses and underwent sufficient prosthetic training.
Cases
The first patient was a 25 year old female who had a second, third, and fourth finger amputation due to blender injury in the workplace. Her fourth finger was replanted but second and third finger was amputated at proximal interphalangeal level. We created body-powered prostheses that mimicking DIP joint motion through MCP joint motion using 3D printer (Cubicon, Single plus, Korea) for the second and third fingers. The source code was the Knick Finger downloaded from e-NABLE and the material used ABS resin for the hard part and TUP resin for the soft part. During the assembly, fishing line and rubber strings were used and the total cost was about 30,000 won. The patient was trained for two weeks on the use of prostheses and she was very satisfied. (Figure 1)
The second patient was a 25 year old male who had left second finger PIP disarticulation during plumbing work. We created body-powered prosthesis using similar method and principle. Jebsen Taylor Hand Function Test results were increased from 65 points before wearing prosthesis to 85 points after wearing. And he said that prosthesis is especially useful when typing on a computer.(Figure 2)
Conclusion
Body-powered, 3D-printed finger prosthesis is feasible and can be applied quickly and easily for finger amputation patients
