(a) Whether it is standard surgery or minimally invasive surgery (laminectomy), the nerve recovery process follows the same rule The main purpose of the doctor’s surgery is to release the nerve compression (the doctor’s job), but the nerve recovery is dependent on the patient himself (the patient’s job), and the doctor cannot help. The effect of surgery = good surgery by the doctor + good recovery by the patient. Both work together and both do their job well so that the patient can be really well. (B) nerve function recovery characteristics 1, pain fast numb slow – that is, pain relief fast and numb relief slow. This is because a short period of compression produces pain, and a long period of compression, before the pressure numbness. However, after the surgery to release the compression, the pain disappeared quickly, but the numbness appeared late, and the relief was slow. This is the result of all our clinical observations. Pain and numbness sometimes coexist, pain is more acute and numbness is masked, but pain is removed quickly after surgery and patients are soon pain-free, numbness is removed slowly and patients often manifest numbness after surgery. Therefore, the newly emerged numbness after surgery, not the problem of surgery, but the law of nerve recovery, pain fast numb slow. 2, pain light numbness heavy – that is, postoperative pain is reduced, numbness increased. There are similarities with the first one. 3, post-operative rebound pain – that is, the pain in the back and legs that appears about 6 days after surgery and disappears about 9 days. Patients are not too worried if they know this before surgery. Otherwise, panic often occurs. 4, the recovery of the disease has volatility – post-operative recovery is unstable, I call this situation “cat a day, dog a day”, until one year after the operation after the best results of stability. The heavier the preoperative, the longer the compression time, the longer the postoperative time to reach a stable state.
