Total joint replacement (TJR) of the lumbar spine is a revolutionary procedure that couples the clinical benefits of neural decompression with preservation of natural motion and sagittal balance at the operative level. The TJR procedure involves reconstruction of the entire motion segment using a posterior bilateral transforaminal approach to access the disc space. The TJR implant (MOTUS, 3Spine, Chattanooga, TN, USA) replaces the function of the intervertebral disc and facet joints, performing biomechanically as a new articulation for the resected, degenerated disc and facets. The implant has been optimized to simulate the kinematic characteristics of the three-joint complex.
