A prospective randomized study to compare discectomy without (DE) and with fusion (DEF) included 63 patients operated on with DE returned to work during the first 9 weeks postoperatively than patients operated on with DEF (p less than 0.005 to 0.05). The prognosis is significantly better for men than for women after DEF (p less than 0.005), while no difference can be shown after DE.
一项比较单纯椎间盘切除术（DE）和椎间盘切除融合术（DEF）的前瞻性随机研究纳入了63例患者，结果显示，接受DE手术的患者在术后前9周恢复工作的人数多于接受DEF手术的患者（p值小于0.005至0.05）。DEF术后男性的预后明显好于女性（p值小于0.005），而DE术后未显示出差异。
