Abstract
Objective To compare the clinical value of approach of microendoscopic discectomy( MED) and open discectomy (OD) in patients with lumbar disc herniation (LDH). Methods 100 patients with lumbar disc herniation according to the different surgical approaches were divided into MED group (n =50) and OD group (n =50) , The indicators of blood loss,operative time,hospitalization time,nerve root injury,relieve sciatica were observed in two groups. Results The rate of excellent in MED group (90. 0% ) were higher than OD group (80. 0% ) (χ~2 = 3.99, P < 0. 05); The indicators of blood loss, operative time, hospitalization time in MED group were less than OD group (t = 2.412,t=2.498,<=2.518,t =2.416,all P<0.05). Conclusion Compared with OD group,MED offer a similar short-term clinical outcome,but with smaller incision,less tissue trauma and quicker recovery.
