Abstract:
[Objective]To explore the clinical character and the treatment method of wedge-shaped vertebral osteotomy,expanding bone graft and spanning segment pedicle screw-rod system fixation from posterior approach to the thoracolumbar kyphosis caused by old fracture.[Method]From June 2003 to May 2008,26 cases of kyphosis deformity at thoracolumbar segment were treated with wedge-shaped vertebral osteoctomy and long segment pedicle screw-rod internal fixation,including 19 males and 7 females and aging 16-45 years(average age:24.2 years).All kyphosis deformity were caused by old thoracolumbar fracture and patients suffered from back pain.The average disease history were 12.6 years.All the sigittal kyphosis Cobb's angles were more than 40 degree cases.Sixteen patients complicated with nervous symptom.Among them 18 cases were given wedge-shaped vertebral osteoctomy and long segment pedicle screw internal fixation,8 cases were given expanding bone graft in anterior of vertebra after osteotomy.The kyphosis angles from radiographs were given compared between pre-and postoperatively,and complications were given analysis too.[Result]Twenty-two patients had been followed up for 12-48 months(average time:34.6 months),all patients' kyphosis angles were corrected satisfactory,the extend of right angle were 86.45%?4.56%.Besides mesenteric artery compressed syndrome happened in 1 patient,other complication was rare.[Conclusion]This method can correct the kyphosis deformity immediately in operation,its correct extent is large,expanding bone graft in anterior of vertebra after osteotomy can reduce the spine shorten and spinal cord injury rate.
