| Background: The scoliosis surgery has been developed for more than 40 years. After the adoption of the 3rd generation implant, great progress has been made in the posterior surgery in its effects, stability and fusion levels. The anterior inner-fixed instruments were first used by Dwyer in 1964. In 1976 Zielke and Stunkat developed VDS( Ventrale Denotation Spondylodesse) which has paved the way for anterior surgery, while it had flaws in the correction of ventrale rotation. In addition, high fusion levels as well as the break of implant show its deficiency in biomechanics. In recent years, some scholars have started to make researches in improving the inner-fixed system of VDS in to treat scoliosis. But there are few reports about the application of anterior correction of congenital thoracolumbar spine kyphoscoliosis.Objective: To review the clinical materials on the application of the China Great Wall Pedicle Screw System in anterior correction of congenital thoracolumbar spine kyphoscoliosis and to observes its sugery effects and follow-up results.Method: There were 18 cases of thoracolumbar scoliosis treated by anterior disc excision, interbody fusion and correction utilizing China Great Wall Pedicle Screw System.Results: All cases were followed from 6 to 24 monthes and had satisfactory correction results. The average preoperative sagittal Cobb angle were 58°(ranged from 41°to 85°),Correction with the postoperative Cobb angle 18°(79%) (ranged from 8°to 30°). The average preoperative coronal Cobb angle were 28°(ranged from 0 to 45°),Correction with thepostoperative Cobb angle 11°(60 %) (ranged from 0 to 35°).Conclusion: Anterior correction of congenital thoracolumbar spine kyphoscoliosis utilizing China Great Wall Pedicle Screw System can achieve satisfactory results with less fusion levels. Follow-up results showed that the corrections were well maintained. The author consider that it is a valuable surgical methods for the correction of thoracolumbar scoliosis.
