What is broad left sub articular 7mm disc protrusion with marked impingement on the traversing l5 root on the left?

A broad left subarticular 7mm disc protrusion refers to a condition where the intervertebral disc has bulged outwards in the left subarticular region, measuring 7mm in size. This protrusion is causing significant pressure on the traversing L5 nerve root on the left side, which can lead to symptoms such as pain, numbness, or weakness in the lower back and legs. The marked impingement indicates that the protrusion is severely affecting the nerve, potentially requiring medical evaluation and treatment options.
