This 3D animation shows foraminal stenosis, a condition where the spinal nerve roots are compressed due to narrowing of the foraminal canals. The video demonstrates how this narrowing occurs, often due to degenerative changes like bone spurs or disc herniation. Viewers can see the impact of this compression on the nerves, leading to pain, tingling, or weakness in the limbs. The animation offers a clear and detailed look at the anatomy involved.
