Abstract：BACKGROUND:Lumbar disc herniation is a clinical syndrome of lumbar pain and radiated pain of the lower limb induced by biochemical changes after intervertebral disc degeneration. Transforaminal endoscopic spine system (TESSYS) and Yeung endoscopic spine system (YESS) are commonly used in the clinic, but their effects are different. <br> OBJECTIVE:To compare the curative effect of TESSYS and YESS in treatment of lumbar disc herniation. METHODS:Fol ow-up data of 134 cases of lumbar disc herniation were retrospectively analyzed. They were assigned to TESSYS group (n=76) and YESS group (n=58). Intraoperative condition, pain at various time points after repair, and lumbar function changes were compared between the two groups. <br> RESULTS AND CONCLUSION:(1) No significant difference in Visual Analogue Scale and Oswestry Disability Index scores was detected between the two groups before repair (P>0.05). At 1, 3, and 6 months after repair and during final fol ow-up, above scores were significantly decreased in both groups (P<0.05). Above scores were significantly lower in the TESSYS group than in the YESS group at various time points after repair (P<0.05). (2) No significant difference in Japanese Orthopedic Association score was found between the two groups before repair (P>0.05). Japanese Orthopedic Association score was greater in the TESSYS group than in the YESS group at 1, 3 and 6 months fol owing repair and during final fol ow-up (P<0.05). (3) The excel ent and good rate was significantly greater in the TESSYS group than in the YESS group during final fol ow-up (P<0.05). (4) Operation time and incision length were significantly shorter in the TESSYS group than in the YESS group. No significant difference in the amount of bleeding was detectable between the two groups (P>0.05). Results suggest that TESSYS for lumbar disc herniation was characterized by smal trauma, mild pain and good recovery of function.
