Abstract Dual-blade plate is widely used in reconstruction of anterior stability of spine. Two hundred and ninety-eight cases were followed up since 1984. Among them, 181 cases were fractureof thoracolumbar spine; 63 cases were tuberculosis of thoracolumbar spine; 43 cases were tumor of thoracolumbar spine; 5 cases were spondylisthesis of lumbar spine; 2 cases were ankylosing spondylitis accompanied with gibbosity; 2 cases were adolescent vertebral epiphysis; I case was hemivertebra; I case was dysplasia of the first lumbar vertebra acompanied with gibbosity. Most cases were successful following operation, but in some cases, the results were unsuccessful, mainly due to the position of the dualblade plate in the vertebral body was not satisfactory. The mistakes most commonly occurred were one or two blades, or a part of the blade going into the intervertebral space, and less commonly seen was deviation of the dual -blade plate from itscorrect orientation or a little side-bent of the blade. Split of the vertebra and fall off of the dual-blade plate were happened in few cases. The causeswere analyzed and ways of prevention were provided in this article.
