Chenna Keshavulu "Design Evaluation and Development of Lumbar Cage" Published in International Journal of Trend in Scientific Research and Development (ijtsrd), ISSN: 2456-6470, Volume-4 | Issue-2, February 2020, pp.1131-1133, URL: https://www.ijtsrd.com/papers/ijtsrd30136.pdf

Lumbar spinal fusion is advance method of surgery to permanently join or fuse two or more vertebrae in the human spine in order to eliminate the relative motion between them. It is currently considered as the most successful surgery in the patients with spinal deformity and degenerative spondylolisthesis. Its success critically depends on the geometric design of the interbody cages and the material properties of the material used. The main objective of this work is to design analyse and develop a 3D model of the intervertebrae disc for human lumbar spine based on anatomical reverse engineering techniques (ARE techniques) such as magnetic resonance imaging (MRI) scan. For this purpose, the sizes of L4-L5 which are the largest vertebrae of the human spine, were observed and modeled accordingly by using CREO with standard dimensions. The prototype was made with PLA plastic using an FDM 3D printer. The analytical tests were carried on ANSYS by applying various complex motions on the intervertebrae disc surface and the stress distributions were compared for the optimization of lumbar cage design. The compression force was applied on the prototype and observed till failure. Results obtained were compared for static position of the lumbar cage, of both analytical and physical outcomes.
