Abstract Scope |
Bones naturally self-repair in the case of fracture or minimal bone loss. However, issues such as misalignment, extensive bone loss, and large fracture sites can hamper this process, especially for load-bearing bones below the waist. Existing procedures can correct misalignment; however, more complex cases require highly invasive permanent solutions like rods or plates. A temporary solution that accommodates loading while the bone regenerates may help avoid such permanent solutions. This study discusses the design, simulation, fabrication, and evaluation of a lattice-based degradable metal implant for load-bearing fracture sites, where the implant gradually degrades as the bone is repaired. The goal is to design a degradable implant to meet the load-bearing requirements while minimizing the amount of material. This study discusses experiments performed to evaluate biocompatibility, tissue-metal interface, and mechanical performance. Along with previously performed material characterization and biocompatibility studies, these investigations are essential to developing a functional degradable metal implant. |
