Aesthetic cosmetic silicone finger prostheses: a systematic review of current advancement and clinical outcomes

Background: Finger amputations significantly impact individuals' functionality, psychosocial well-being, and quality of life, necessitating prosthetic solutions that balance aesthetic appeal and functional restoration. Objective: This systematic review examines advancements in finger prosthesis design, materials, fabrication techniques, clinical outcomes, and patient satisfaction. 24 studies were analyzed focusing on silicone biomaterials, suspension methods, cosmetic glove-like prostheses, and impacts on daily living. Key findings highlight silicone's aesthetic importance, innovations in suspension, and variable outcomes on hand function. The review underscores the balance between aesthetic appeal and functional capability in finger prostheses. Method: A systematic search was conducted in databases including PubMed, Scopus, and Web of Science for studies on finger prostheses. Twenty-four studies meeting inclusion criteria were analyzed focusing on silicone biomaterials, 3D printing, suspension techniques, impacts on activities of daily living (ADL), hand function, and patient satisfaction. Studies focusing on finger prostheses for human subjects. The methodological quality of included studies was assessed considering factors like study design, sample size, outcome measures, and reporting clarity. Given the heterogeneity of study designs (case reports, clinical studies), a narrative synthesis approach was adopted. Results: Silicone is widely used for aesthetic finger prostheses due to its lifelike appearance. Innovations in suspension methods contribute to comfort and functionality. Clinical outcomes show variable effects on hand function and grip strength. Patient satisfaction is generally positive, driven by aesthetics and comfort. The interplay between aesthetic and functional aspects is crucial in prosthesis design. Conclusion: Finger prostheses have seen advancements in materials and techniques. Personalized approaches considering aesthetics and function are important for optimal outcomes. Further research is needed on optimizing functionality and long-term clinical outcomes.
