【Abstract】 Objective To study the diagnosis and treatment of the far lateral lumbar herniation. Methods 12 cases of far lumbar disc herniation were analyzed in clinical manifastation, features of photography and operation methods. Results Among 12 cases, there was 1 patient herniated in L 3～4 and 8 patients herniated in L 4～5 , 3 patients herniated in L 5～S 1. Far lumbar disc herniation was mainly involved in the upper nerve root,which was confirmed by operation, and 7 cases were treated with the approach by outer edge of pars interarticularis. The symptoms were obviously improved in 11 cases,and partially improved in 1 case. Conclusion Far lumbar disc herniation is mainly involved in the upper nerve root. The approach by outer edge of pars interarticularis shows the advantage of good exposure, less blood loss and no effect on the lumbar stability.更多还原
