Abstract:
Objective To observe the clinical efficacy of posterolateral lumbar fusion (PLF) and posterior lumbar interbody fusion (PLIF) in treatment of lumbar intervertebral disc protrusion. Methods A total of 105 patients with lumbar inter-vertebral disc protrusion were divided into two groups according to the surgical procedures. 52 cases in the PLF group were treated by PLF and 53 cases in the PLIF group were treated by PLIF. The surgical effects were compared. Results The two groups had no difference in operation duration, intraoperative blood loss and hospital stay, and there was no significant difference (P>0.05). The total effective rate was 94.34% in PLIF group, higher than 80.77% in PLF group, and there was sifference between two groups (P<0.05). Both groups had increase of intervertebral height and segmental angle, but PLIF group had significantly greater increase of intervertebral height and segmental angle, and there was significant difference between two groups ( P<0 . 01 ) . The surgical complication rate was 7 . 55% in PLIF group and 15.38% in PLF group, and there was significant difference(P>0.05). Conclusion PLIF has significant effects for treat-ment of lumbar intervertebral disc protrusion with greater protrusion or segmental instability. PLIF can promote fast re-covery of the supporting function of the anterior lumbar column and reconstruction of lumbar physiological curvature, which is consistent with lumbar biomechanical principles. PLIF has significant meaning in promoting early recovery of lumbar functions and improving life quality.
