Patient: Description of condition (main symptoms, onset of lumbar disc surgery, walking limp, left leg weak, cramps from time to time, left foot can not stand on tiptoe Laboratory, lumbar 5 sacral 1 prolapse with slippage Last December the pain is unbearable, can not sleep, but not numb, after the orthopedic, traction, even pain and then numb, walking limp, left leg muscle atrophy, surgery in March this year, all symptoms reduced after surgery, but the skin of the left leg still feels diminished. Why do I have this symptom? I have consulted many patients after surgery, and none of them have this phenomenon of mine. I am on fire, and I can’t go to work now, so please give a look at the film to see if it is normal. Ren Shou Song, Department of Spine Surgery, People’s Hospital of Jimo: The non-recovery or unsatisfactory recovery of certain neurological functions after lumbar discectomy is a difficult problem to explain, and the reasons are rather complex. The main reasons are as follows: 1. The recovery process of demyelinating lesions of the nerve is very long, and it takes 3 months to 6 months for minor lesions, and even longer for severe cases. The degeneration of the sensory effector is time-limited, and the sensory vesicles on the skin degenerate after even if the nerve conduction is restored there will be no recovery of sensation. For example, if a light bulb is broken before the circuit is repaired, the light will not light up even after the circuit is repaired. 2. Irreversible damage to the nerve roots, because of the severity of the lesions leading to irreversible damage to the nerve roots, even after good surgical decompression, some functions cannot be restored. On this point, the surgeon will usually make a detailed explanation to the patient before the surgery. 3. The chances of this occurring are very small in the case of inadvertent injury or incomplete decompression during surgery, or defective choice of surgical approach. Instead of improvement or unsatisfactory improvement, the symptoms worsen after an inadvertent nerve injury. Nerve damage can be confirmed using electrophysiological examination. Your current situation is clearly not such a case. 4, the patient’s misperception or lack of doctor-patient communication, this situation is the most common. Your condition is not very well understood because I cannot see you in person. The recovery of nerve function cannot be judged only by the patient’s subjective sensation. Many patients who supposedly do not recover their sensation will show that the sensation is good when they do a neurological examination, but in fact it is just a nerve irritation symptom. In other cases, the so-called poor recovery is actually a new symptom, not a symptom of a nerve root that was examined before the surgery. According to the three MR photos you uploaded, my opinion is as follows: 1, the surgery should be done, there is no problem with the indications, that is to say, it is not a surgery that should not be done, the film shows that it should be the rupture and prolapse of the disc (a more serious situation) 2, I do not understand the mode of surgery, look at the film should only be a simple lumbar discectomy, which is a very limited surgical treatment, that is to say, the doctor This is a very limited surgical treatment, that is, the doctor did not give you a great surgery, this choice is more consideration for the interests of the patient. However, this balance is sometimes difficult, because excessive medical treatment is detrimental to the patient’s interests, and the appropriate limited surgery is responsible for incomplete treatment, so you should be more understanding of the doctor’s difficulties. 3, Both post-surgical films prove that the resection of the prolapsed disc was complete and the decompression was perfect. 4, There is absolutely no need to repeat the MR examination. One film is all that is needed. 5, The left nerve root cuff is narrower on the image than the right, but this does not indicate any problem. It cannot be judged from this sign that the left nerve root is still compressed. 6.Neurotrophic drugs, vitamin B1, B12 (or Micropôle), anti-inflammatory and analgesic drugs and herbal medicines are recommended. 7.If there is lumbar instability and severe nerve entrapment, we can consider whether to have a second surgery according to the situation, but I don’t think this is very likely. 8, the treatment of the disease is not KFC and McDonald’s like there will be a uniform production standards, each patient’s condition is completely different, you can not use other patients’ feelings to control their own efficacy, you need to control your own changes before and after surgery, whether it is improved or aggravated. Because you have provided very little information, and because you cannot be examined in person, what you say may not be accurate, and I would like to provide you with reference.
