A Systematic Review of Natural Fiber-Reinforced Polymer Composites in Prosthetic Socket Fabrication

Abstract

This review systematically examines the burgeoning field of natural fiber-reinforced polymer (NFRP) composites in prosthetic socket fabrication. The review begins by exploring the historical context and recent shift towards sustainable and biocompatible materials in prosthetics, with a specific focus on NFRP. It delves into the composition and properties of NFRP, detailing the types of natural fibers used and the characteristics of these innovative composites. The review highlights the advantages of NFRP in prosthetics, notably their biocompatibility, sustainability, and mechanical properties that are pertinent to prosthetic applications. The technical aspects of fabricating prosthetic sockets with NFRP are examined, discussing both traditional and advanced manufacturing techniques and design considerations that take into account anatomical and biomechanical factors, as well as the need for customization. The clinical outcomes and user experiences with NFRP prosthetic sockets are evaluated, focusing on their durability, functionality, and comparison with traditional materials. User-centric perspectives, including comfort, satisfaction, and adaptation challenges, are also considered. Crucial challenges and limitations in the field are identified, such as technical and fabrication complexities, consistency and quality control issues, as well as clinical and practical barriers like accessibility, cost, and the necessity for specialized training. The review outlines future directions and research needs, emphasizing potential innovations in NFRP, integration with emerging technologies, and the importance of translational research and interdisciplinary collaboration. The review underscores the significant role NFRP could play in advancing prosthetic technology, envisioning a future where prosthetic design is not only user-friendly and functional but also sustainable
