Abstract Objective To explore the therapeutic effect of nerve root blocks in percutaneous transforaminal endoscopic discectomy for degenerative lumbar disease. Methods From January 2015 to March 2019, the nerve root block technique was applied in 38 patients of degenerative lumbar disease with unilateral symptoms, including 19 cases of lumbar disc hernination(LDH),11cases of lumbar spinal stenosis (LSS) and 8 cases of both. After never root blocking, patients with a positive single responsibility segment underwent trasnforaminal endoscopic discectomy. The clinical outcomes were evaluated with Visual Analogue Score (VAS) and Oswestry Disability Index(ODI). Results 1.The nerve root block: 33 cases with clear responsibility segments were subjected to transforaminal endoscopic discectomy,2 cases were identified as having two responsibility segments and 3 cases had no clear responsibility segments. 2.Surgery: the symptoms of patients after operation were significantly relieved. The VAS and ODI of patients were improved significantly two weeks after operation (P<0.05), especially during the last follow-up (P<0.05). Conclusions The nerve root block can be a more specific diagnostic method for patients with degenerative lumbar disease, provide reliable evidence for the selection of surgical segments for transforaminal endoscopic discectomy, and serve the purpose of precise and minimally invasive treatment.
