Prospective Comparison between the Anterior Interbody Fusion and the Posterolateral Fusion / 대한척추외과학회지

ABSTRACT

OBJECTIVES: To campare the differences of clinical and radiological results between the posterolateral fusion and the anterior interbody fusion. MATERIALS AND METHOD: For prospective study, the anterior interbody fusion was performed in 20 patients(Group I) and the pos-terolateral fusion was performed in 20 patients(Group II). The operation time, pre- & post-operative hemodynamic changes, functional recovery and fusion rate were compared. RESULTS: The average operation time was 180 min in group I and 100 min in group II. The average estimated blood loss and transfusion amount were assessed 1225cc, 926cc in group I and 1034cc, 880cc in group II. Clinical results were as follows excellent 25%, good 65%, fair 10% in group I and excellent 15%, good 50%, fair 30%, poor 5% in group II. The fusion rate was 100% in group I and 75% in group II. CONCLUSION: The anterior interbody fusion with posterior instrumentation is considered encouraging operative methods.
