Objective To compare the therapeutic effect of Microendoscopic Discectomy (MED) with love's method for the treatment of lumbar disk herniation. Methods Pre- and postoperative JOA score, the length of incision, blood lost, operative time existed weight of disk, body temperature variation and time on getting out of bed after operation were compared between the MED group and the love's method group randomized 35 cases respectively since December 1999. Results The preoperative JOA scores in the MED group and the love's method group were 12.1?1.8 and 12.1?1.4, respectively (t=0.437, P=0.663); The postoperative JOA scores in both groups were 26.9?1.6 and 26.1?5.3, respectively (t=1.81, P=0.0077); The length of incision were (2.0?0.1)cm and (5.0?0.6)cm, respectively (t=26.72, P
