At 12-months post-injury, degeneration was observed in non-injured lumbar discs. Secondary degenerating IVDs were similar to the injured discs by X-ray (narrowing) and T2-MRI (internal disc disruption) but did not show abnormal innervation. Increased physical activity had no impact on mechanically injured IVDs, but attenuated disc narrowing at other lumbar levels. Mechanical injury of L4/5-IVDs induces delayed radiating pain and degeneration of adjacent discs; increased physical activity positively mitigated both. Mechanical injury of L4/5-IVDs induces delayed radiating pain and degeneration of adjacent discs; increased physical activity positively mitigated both. We developed a software program that automatically extracts a three-dimensional (3D) lumbar nerve root image from magnetic resonance imaging (MRI) lumbar nerve volume data using artificial intelligence. The aim of this study is to evaluate the morphology of Kambin's triangle in three dimensions based on an actual endoscopic transforaminal surgical approach using three-dimensional (3D) computed tomography (CT)/ magnetic resonance imaging (MRI) fusion images of the lumbar spine and nerve tissue. Three-dimensional lumbar spine/nerve images of 100 patients (31 males and 69 females; mean age, 66.8years) were used to evaluate the relationship between the superior articular process (SAP), exiting nerve root (ENR), and dural canal at the L2/3, L3/4, and L4/5 levels at 45° and 60° approach angles. The SAP-ENR distance at 60° was the greatest at L4/5 and was significantly greater at L2/3 and L4/5 than at L3/4 (P < 0.01, P < 0.01, respectively). The SAP-ENR distance at 45° was the greatest at L2/3, and it waould be useful for examining parameters, including bones and nerves, to ensure the safety of surgery. Ne
