Abstract
We evaluated the clinical results of anterior decompression and reconstruction using the Kaneda-SR system. Twenty-nine cases with the thoraco-lumbar injury (15 men and 14 women) with neurological deficits were treated by anterior decompression and internal fixation by Kaneda-SR system. There were 23 burst fractures, 2 flexion-dislocation injuries, and 4 cases of posttraumatic vertebral collapse. The mean age of the patients at the time of operation was 46 years (range 17-77 years). The mean follow-up was 26.6 months. The modified Frankel score improved more than one degree in 82.6% of the 19 paresis cases. Postoperative pain evaluation was scored with the Denis pain scale, and 82.8% of the 29 cases had good pain relief (P1 or P2). Bony union occurred in all cases. Mean loss of reduction was 2.8 degrees. Postoperative complications included 1 case of MRSA pneumonia,2 cases of superficial infection, 2 cases of urinary tract infection, and 1 case of postoperative vertebral collapse in the adjacent level.
