Abstract：Objective To study clinical results and surgical technique of posterior lumbar interbody fusion in the treatment of discogenic low back pain. Methods A total of 71 patients with discogenic low back pain underwent open discectomy and posterior lumbar interbody fusion with autograft from unilateral side with pedical screw instrumentations. Hospital records were reviewed for patients’ improvement of symptoms and fusion rate in different follow up periods. Results The mean follow up time was 37.3 months ( range: 23-67 months ). Effective pain relief and functional improvement were obtained. Visual analogue scale ( VAS ): ( 7.9±0.4 ) point preoperatively and ( 1.1±0.3 ) postoperatively ( improvement rate: 83.52% ). Oswestry disability index ( ODI ): ( 61.7±5.5 ) point preoperatively and ( 22.8±4.4 ) point postoperatively ( improvement rate: 72.66% ). Bone graft gap contour was unclear 6-9 months postoperatively. CT showed no obvious bright areas in the junction of the vertebral bone and graft. Fusion failure was found in 12 cases, but preoperative symptoms were relieved significantly. Conclusions Posterior lumbar interbody fusion with pedical screw fixation is a sound method in the treatment of discogenic low back pain and it is also an ideal method to reconstruct the stability of the lumbar spine.
