A Retrospective Study of Thoracolumbar Fractures Treated with Fixation and Nonfusion Surgery of Intravertebral Bone Graft Assisted with Balloon Kyphoplasty.

Abstract：

BACKGROUND:Posterior fixation and fusion is the primary treatment for thoracolumbar fractures, although this treatment may sacrifice range of motion (ROM) to achieve stability, rather than treating the fracture itself. Two issues addressed when treating thoracolumbar fractures are 1) replacing the fractured vertebrae, especially the upper end plate of the injured vertebrae and 2) providing strong fixation with biomechanical stability and flexibility. METHODS:This retrospective study included 61 consecutive patients with thoracic or lumbar fractures treated from October 2010 to May 2014. Patients were divided into 1 of 2 groups: group A, intravertebral bone graft with balloon kyphoplasty (nonfusion surgery), and group B, traditional posterior fixation and fusion surgery. The visual analog scale was used preoperatively and at 3 months, 1 year, and 2 years. Radiography, computed tomography, and magnetic resonance imaging were performed preoperatively. Radiography was performed postoperatively at 3 months and 2 years. At 3 months after surgery, computed tomography was used to confirm healing of the vertebral fracture. RESULTS:All fractures in both groups were reduced successfully, and deformities were improved. After the removal of hardware in group A, ROM at the injury level recovered, and at 2 years, there was no loss of vertebral height or recurrence of deformity. There was no hardware failure in group A, but there was evidence of screw loosening in 3 screws in group B. CONCLUSIONS:Nonfusion treatment of intravertebral bone graft assisted with balloon kyphoplasty showed good fracture reduction, deformity correction, fracture healing, and ROM maintenance. There were no complications associated with the implant.
