Lumbar Spinal Stenosis Dynamic Disc Model (LxD)
A recently updated lumbar spinal stenosis model with the newest anatomical detail including both lateral recess stenosis and the newest feature of foraminal stenosis from an enlarged projecting osteophyte from the right superior articular process of L5. Details extracted from real cadaveric bone that includes a L4-5 motion segment with a reduced lordotic curve and significant disc height loss. Features include subchondral sclerosis, facet arthropathy and a thickened ligamentum flavum. Optional cauda equina and rootlets that demonstrate increases friction in dynamic extension and more mobile in dynamic flexion. Wonderful education tool to understand elements of central, lateral and foraminal stenosis. As of Jan 2021, the disc and cauda equina created with a translucent material as the photos show.
