Design of a Transforaminal Lumbar Interbody Fusion (TLIF) Spine Cage

Lumbar Interbody Fusion is a technique used to treat various spinal disorders, which has many types, such as the Transforaminal Lumbar Interbody Fusion (TLIF) Technique. With TLIF being one of the most well-known techniques, which many spinal surgeons are trained and skilled at, there are various types of TLIF Spine Cages available on the market. In this paper, we designed a TLIF Cage and compared the simulation's analysis with the prototype's experimental testing. The design was developed using the reverse engineering method, and findings on the jaws profile and other design considerations through literature review. The design was then analyzed through a simulated compression test using Ansys Software. The simulation showed that the designed TLIF spine cage in this paper can withstand the force usually given to an implanted lumbar spinal cage.
