A research team compared functional outcomes and patient satisfaction between a hook terminal device that was fitted in a clinic with a 3D-printed prosthesis with a functional hand that was fitted remotely. The patient was a 59-year-old male with a traumatic transradial amputation of his dominant arm. The 3D-printed arm resulted in improved gross manual dexterity and improved performance in bimanual coordination as measured by the Box and Block test. However, the standard hook device scored higher in patient satisfaction surveys. The researchers said that the patient’s concerns with the 3D printed prosthesis were its durability and effectiveness.
The study’s authors set out to evaluate whether rapid fabrication allowed by 3D-printed devices could lead to a reduction in prosthesis rejection if users can interact with a prosthesis soon after amputation surgery.
The patient received a 3D-printed transradial prosthesis that was remotely fitted and manufactured using photogrammetry. Assessments were performed first with the standard hook prosthesis and then with the 3D-printed device after a five-week familiarization period. Functional outcomes were evaluated using the Box and Block Test and Bimanual Coordination Tray Test. Patient satisfaction was evaluated using the QUEST 2.0 and the modified OPUS self-reported questionnaires).
The results, “Functional performance and patient satisfaction comparison between a 3D printed and a standard transradial prosthesis: a case report,” were published in BioMedical Engineering OnLine.
