“…A desktop 3D-printed external fixator using fused deposition modeling only requires filament for component creation. 5,7,[9][10][11][12][13] The external fixators in this study were printed using PLA, which is one of the lowest cost and most commonly used materials in desktop 3D printing. Although PLA does have high strength relative to its cost, filaments such as polyether ether ketone (PEEK) and PLA reinforced with carbon fiber have demonstrated superior strength qualities.…”

Introduction: External fixation is a critical component of orthopaedic fracture management and is used for various conditions, including trauma and pediatric orthopaedics. However, the availability and high cost of external fixation devices are a concern, especially in rural and developing countries. 3D printing technology has shown promise in reducing manufacturing costs and improving accessibility to external fixation devices. The purpose of this study was to evaluate the mechanical properties of a fully 3D-printed desktop external fixation device and compare the results with the mechanical properties of commonly used, clinically available external fixators. Methods: A fully 3D printable external fixator was designed and printed in polylactic acid at two infill densities, 20% and 100%. The mechanical properties of the 3D-printed external fixators and several commercially available fixators were tested according to applicable sections of the American Society for Testing and Materials F1541 standard protocol in axial, medial-lateral, and anterior-posterior orientations. The primary outcomes measured included failure load, safe load, rigidity, and yield load. The mean differences between experimental and control groups were calculated using one-way analysis of variance and Tukey tests. Results: The 20% infill 3D-printed construct showed poor performance compared with commercially available external fixators in all testing conditions and across most variables. The 100% infill 3D-printed construct was comparable with or superior to all commercially available devices in most testing conditions. The cost for printing a single 3D-printed 100% infill external fixator was $14.49 (United States Dollar). Discussion: This study demonstrates that a low-cost desktop 3D printer can create an entirely 3D-printed external fixator that resists clinically relevant forces similar to medical-grade industry-standard external fixators. Therefore, there is potential for customizable and low-cost external fixators to be manufactured with desktop 3D printing for use in remote areas and other resource-constrained environments for fracture care.

3D Printed Orthopaedic External Fixation Devices: A Systematic Review

et al. 2023

View full text Add to dashboard Cite

Background External fixators are complex, expensive orthopaedic devices used to stabilize high-energy and complex fractures of the extremities. Although the technology has advanced dramatically over the last several decades, the mechanical goals for fracture stabilization of these devices have remained unchanged. Three-dimensional (3D) printing technology has the potential to advance the practice and access to external fixation devices in orthopaedics. This publication aims to systematically review and synthesize the current literature on 3D printed external fixation devices for managing orthopaedic trauma fractures. Methods The Preferred Reporting Items for Systematic Review and Meta-Analysis (PRISMA) protocols were followed for this manuscript with minor exceptions. PubMed, Embase, Cochrane Review, Google Scholar, and Scopus online databases were systematically searched. Two independent reviewers screened the search results based on predetermined inclusion and exclusion criteria related to 3D printing and external fixation of fractures. Results Nine studies met the inclusion criteria. These included one mechanical testing study, two computational simulation studies, three feasibility studies, and three clinical case studies. Fixator designs and materials varied significantly between authors. Mechanical testing revealed similar strength to traditional metal external fixators. Across all clinical studies, five patients underwent definitive treatment with 3D printed external fixators. They all had satisfactory reduction and healing with no reported complications. Conclusions The current literature on this topic is heterogeneous, with highly variable external fixator designs and testing techniques. A small and limited number of studies in the scientific literature have analyzed the use of 3D printing in this area of orthopaedic surgery. 3D printed external fixation design advancements have yielded promising results in several small clinical case studies. However, additional studies on a larger scale with standardized testing and reporting techniques are needed.
