I Have A CT Scan W/contrast And My Doctor Says

I have a CT Scan w/contrast and my Doctor says I am good from the pictures, Fused from T10-S1, still unable to walk, been 4 months since surgery and legs feels like weigh 200 lbs when stand and feel like in concrete. Can walk in place but can't walk more than 20 feet in walker. Would like someone to read my CT Scan and give opinion.
