Patient: Description of condition (onset, main symptoms, hospital visited, etc.): Patient, male, 65 years old. leg pain occurred on August 24, with paroxysmal onset, which later worsened and affected normal life. He had similar symptoms before and got better after rest. On September 7, he was admitted to the specialty unit of Hefei Second Hospital, where he underwent interventional therapy twice before and after, and the pain improved. Recently, he still could not get out of bed and walk, and the pain increased at night, and he took oral anti-inflammatory pain once a day. During the check-up this morning, the doctor said that the calcification point was in the conus compressing the nerve, and surgery was needed, but it was extremely risky. Yesterday, a similar patient in Anhui Provincial Hospital was paralyzed after surgery, so I’m asking if you have any good treatment plan. Dr. Zhang: I haven’t seen your imaging data, so I don’t know the details of the protruding compression, but according to our past experience, if there are symptoms of pain at this age, especially if the pain is severe, generally speaking, conservative or minimally invasive methods are not effective, and the patient’s pain can be very severe and unbearable, and this situation requires surgery. As for the risk of surgery, objectively speaking, no hospital or doctor can guarantee 100%, the risk is only theoretically possible, it is a matter of chance. The risk should not be too great for the lumbar spine, which is still relatively mature, and the results are not bad. We just had a similar one done the day before yesterday. So if the pain is great, surgery is still recommended. This should be the formal measure.
