Brief Answer: L4 L5 may need surgical repair Detailed Answer: Hi, Thanks for your query. I believe the above post is a Scan report and it says that the lesion at the L4-L5 vertebra is complicated and severe leading to spinal cord compression. It is necessary for it to be surgically corrected at the earliest. I would like to know what doubts do you have pertaining to the above report. Waiting to answer,
