What is unroofing of l4-l5 disc?

Unroofing of the L4-L5 disc refers to a surgical procedure where a portion of the bony structure above the intervertebral disc at the L4-L5 level is removed to alleviate pressure on the spinal nerves or the spinal cord. This procedure is typically performed when there is significant disc herniation or degeneration causing pain, neurological deficits, or other complications. By removing the bony roof, the surgeon aims to create more space for the affected nerve roots and improve the patient's symptoms.
