AbstractAxial lumbar interbody fusion is a novel percutaneous alternative to common open techniques, such as anterior, posterior, and transforaminal lumbar interbody fusion. This minimally invasive technique uses the presacral space to access the L5-S1 and L4-L5 disk space. The goal of this study was to examine outcomes following axial lumbar interbody fusion. The charts of all patients who underwent axial lumbar interbody fusion surgery at our institution between 2006 and 2008 were reviewed. Clinical outcomes included visual analog scale (VAS) and Oswestry Disability Index (ODI). Radiographs were also evaluated for disk space height, L4-L5 and/or L5-S1 Cobb angle, and fusion. Of the 50 patients (32 women, 18 men; mean age, 49.29 years) treated with axial lumbar interbody fusion, 48 had preoperative VAS scores and 16 had preoperative ODI scores available. Complete radiographic data were available at the preoperative, initial postoperative, and final postoperative time points for 46 patients (92%). At last follow-up (average, 12 months), ODI scores were reduced from 46 to 22, and VAS scores were lowered from 8.1 to 3.6. Of the 49 patients with postoperative radiographs, 47 (96%) went on to a solid fusion. There were no significant differences between pre- and postoperative disk space height and lumbar lordosis angle. The most common complications were superficial infection and pseudoarthrosis. Other complications were rectal injury, hematoma, and irritation of a nerve root by a screw. Overall, we found the axial lumbar interbody fusion procedure in combination with pedicle screw placement to have good clinical and radiological outcomes.Copyright 2010, SLACK Incorporated.
