INTRODUCTION: There are several practical problems encountered in the TLIF procedure with implantation of two @entity702 cages, such as difficulty in achieving symmetric positioning with two cages, loosening of the first cage following insertion of the second cage and higher direct costs to the @entity1 . METHOD: From January 2005 to December 2007, a total of 76 consecutive @entity1 treated with instrumented TLIF with single cage and excised local bone were enrolled in the current study. There were 45 males and 31 females aged between 31 and 75 years (mean 50.9 years). Forty-five @entity1 had @entity179 alone, 23 had associated isthmic or degenerative spondylolisthesis and 8 had recurrent disc herniations. Clinical outcomes were evaluated using the Oswestry Disability Index and a visual analog scale. Intervertebral height and fusion status were assessed on X-ray and two-dimensional computed tomography reconstruction. RESULTS: All the @entity1 followed up. The mean follow-up period was 21.8 months (range from 12 to 48 months). No nerve @entity130 occurred during operation. Postoperative ODI and VAS scores in all the @entity1 were more than the preoperative ones with significant differences. All the @entity1 had complete interbody fusion and, at the final follow-up, none had instrumentation failure. Postoperative intervertebral height in all the @entity1 was better than the preoperative ones with statistical significances. CONCLUSIONS: Instrumented TLIF with single cage is a safe and effective method for the treatment of @entity179 .
