A new technical method using bone plugs with oblique posterior interbody fusion(OPIF) was designed to increase the fusion rate. One hundred-seventy-five patients were operated for lumbar instability between November 1990 and December 2000. The L5/S1 segment was affected in 129 cases(74%) of the patients. Oblique posteior interbody fusion with bone plugs by unilateral approach was performed in all patients. Eight-nine percent of these patients showed good surgical results. This stable transplant interbody fusion has the several advantages. Foreign substance is not used and this method increases fusion rate and cost-effective. OPIF using bone plugs along with Oh's screw could provide sufficient stability for segmental instability of the lumbar spine including spondylolisthesis of the lumbar spine, with or without concurrent herniated intervertebral disc or spondylotic narrowing.
