<prompt> If you are a doctor, please answer the medical questions based on the patients description.Lateral spine view: there is a 6-7 mm subluxation of l4 and l5. Narrowing of the disc space. Also narrowing of the l3 l4 space and minimal retrolisthesis of l3 with respect to l4 approx 5 mm.MRI recommended...would that show anything different than above?Can this cause my feet to be numb and sciatic area pain from buttocks to legs?What is usual treatment? What should I avoid doing? until I talk to dr.  <response>: Hi, Yes, an MRI would definitely be indicated in your case, and you should probably get one done. X-rays show only the bony abnormalities and do not tell us anything much about nerve root compression which is the cause of sciatica, numbness, weakness, etc. An MRI would give these details. Subluxation indicates movement of one vertebra over the adjacent Im assuming it is anterior subluxation of L4 over L5 and retrolisthesis means backward movement of the vertebra over the lower one L3 over L4. These are usually due to break in the posterior vertebral portion lysis or due to facial arthropathy, both of which are not mentioned in your X-ray report. Subluxationlistless often leads to compression of nerve roots and needs to be operated if symptoms are severe. You would need to meet an orthopedic surgeon to discuss your options. Till then, avoid lifting heavy objects, doing heavy work, etc. and wear a lumbar support belt if you have one. Sincerely, Vamshi
