BackgroundMany surgical methods are available for repairing thoracolumbar fractures including short-segment internal fixation with posterior pedicle screws and anterior decompression and reduction. However, most methods are associated with significant surgical trauma and long postoperative recovery. The purpose of this study was to describe anterior single level interbody fusion and fixation for the repair of thoracolumbar fractures which may reduce surgical trauma and help speed recovery.MethodsA group of 21 patients who underwent single level anterior interbody fusion and fixation from June 2006 to June 2011 were compared with a group of 21 patients who underwent double level anterior interbody fusion and fixation during the same period. The groups were compared with regard to operation time, intraoperative blood loss, fracture healing time, ratio of pre- to postoperative endplate height between adjacent vertebrae, Cobb angle in the sagittal plane, recovery of neural function, and internal fusion failure.ResultsThe 2 groups were similar with the exception of fracture location (P=0.017). The patients who underwent the single level procedure had a shorter operation time (P < 0.001), less blood loss (P < 0.001), and shorter follow-up (P < 0.001). Both groups had significant improvement in Cobb angle at 1 week and 1 year after surgery, but there was no significant difference between the groups. Both groups also exhibited improvement in neurological function, and the difference in improvement between the groups was not significant.ConclusionsSingle level intervertebral fusion and internal fixation for thoracolumbar fractures provides as satisfactory an outcome as the traditional approach, double level anterior interbody fusion and fixation, and reduces the degree of surgical trauma.
