OBJECT: The authors conducted a study to evaluate and compare prospectively the implantation of either an empty @entity505 fiber composite frame cage (CFCFC) or an iliac crest autograft after @entity4048 ( @entity4048 ) for @entity890 with monoradiculopathy. METHODS: Thirty-six consecutive @entity1 with one-level @entity614 due to single-level @entity890 were treated by @entity4048 , and implantation of either an empty CFCFC (24 @entity1 ) or an iliac crest autograft (12 @entity1 ). Radiological and clinical assessments were performed preoperatively, immediately postoperatively, and at 3, 6, and 12 months postoperatively. Fusion at the 12-month follow-up examination was demonstrated in 96% of the @entity1 in the cage group and in 100% of those in the autograft group. The mean anterior intervertebral body height was 3.7 mm preoperatively and 3.9 mm at 12 months in the CFCFC, @entity676 .8 mm, respectively, in the autograft group. In cage-treated @entity1 , @entity4048 , as measured using the visual analog scale (VAS) (Score 0 = minimum; 10 = maximum) decreased from 6.4 preoperatively to 2.0 at 12 months, and @entity158 decreased from 8.4 preoperatively to 1.5 at 12 months. In the autograft group, @entity4048 changed from a mean preoperative VAS score of 7.2 to 2.5 at 12 months, and @entity158 decreased from a preoperative mean of 7.8 to 1.4 at 12 months. Analysis of the 12-Item Short Form Health Survey domains and the @entity717 Index scores indicated a significant improvement in both the Physical and Mental Component Summary domains in both groups. CONCLUSIONS: Implantation of an empty CFCFC or a tricortical iliac crest autograft after @entity4048 are safe and reliable options for the treatment of @entity890 causing one-sided @entity614 . Both procedures produced equally satisfying clinical and radiological results, leading to a high fusion rate and maintaining intervertebral height. Implantation of an empty CFCFC has the advantages of avoiding any donor site morbidity and requiring a significantly shorter operative time.
