Abstract:
Objective To modify the anterior fixation technique for thoracolumbar fractures so as to reduce blood loss and improve the success rate of the first vertebral screw implantation. Methods Only surface artery of the injured vertebrae was ligated and the discs adjacent to the burst vertebra excised. Then,the mass autograft ilium was harvested with most cartilage terminal lamina left. The bursted vertebra was resected so that the vertebral canal could be decompressed thoroughly. Structural ilium graft was performed,followed by Z-plate being placed and locked. Results The modified operative technique was used to treat 87 cases,of which 76 cases of fresh thoracolumbar fracture had hemorrhage capacity about 400-800 ml (average 560 ml) as well as operation time for 2.5-3 hours,and 11 cases with old fractures had hemorrhage capacity about 800-1 200 ml (average 1 080 ml) as well as operative time for 3.5-4 hours. Eighty-one cases with kyphosis deformity was completely corrected,four cases had kyphosis deformity of 5?-8? and two lordosis. A total of 39 cases with post-operative paralysis basically recovered,28 partially recovered,nine recovered fractionally and 11 was beyond recovery. No aggravation was found in post-operative nerve syndrome. Conclusions The modified anterior fixation technique is excellent in reducing blood loss,shortening the operation time and increasing the success rate of the primary vertebral screw implantation. [
