Abstract:
STUDY DESIGN: This is a retrospective study analysing and comparing what between posterior lumbar interbody fusion plus posterior lateral fusion(PLIF+PLF) and PLF alone for Spondylolisthesis(Degenerative type+Isthmic type). Thirty patients were treated by posterior lumbar interbody fusion(PLIF) using Harms' cage and posterolateral fusion(PLF) with transpedicular screw fixation. Forty-nine patients were treated by posterolateral fusion with transpedicular screw fixation. OBJECTIVES: This is to verify the advantages of adding posterior lumbar interbody fusion using Harms' cage to the usual posterolateral fusion with transpedicular screw fixation SUMMARY OF BACKGROUND DATA: Interbody fusions have certain distinct mechanical advantages over posterolateral ones. Autologous cancellous bone is the preferred graft material, but might be soft to maintain the disc space during fusion. METHODS: Union rate, slip reduction, sagittal angle correction, disc height restoration, and clinical results by Lin's criteria were analysed. RESULTS: Nonunion was observed in 5 PLF cases(10%) and one PLIF case(3%). Loss of slip reduction was 0.7% in PLIF and 2.59% in PLF(P<0.05). Loss of sagittal angle correction was 1.27degreein PLIF and 3.65degreein PLF(P<0.05). Loss of disc height restoration was 2.6% in PLIF and 7.6% in PLF(P<0.05). Clinical evaluation in PLIF+PLF was excellent in 67%, good in 30%, and fair in 3%. Clinical evaluation in PLF was excellent in 59%, good in 33%, and fair in 8%. More excellent results were noted in PLIF+PLFcases. CONCLUSIONS: Adding posterior lumbar interbody fusion using Harms' cage showed better radiological results and more excellent clinical results compared to posterolateral fusion with transpedicular screw fixation.
