Abstract:
BACKGROUND:Spinal canal decompression and fusion combined with pedicle screw fixation has become the main method for the treatment of thoracolumbar fracture and dislocation. OBJECTIVE:To restore the vertebral height of the patients with thoracolumbar fracture and dislocation who underwent subtotal resection and decompression through titanium cage packed with autologous cancel ous bone and pedicle screw fixation. METHODS:Thirty-one patients with thoracolumbar fracture and dislocation treated in the Shanghai 6th People’ s Hospital of Shanghai Jiao Tong University from February 2007 to September 2011 were selected. Al the patients received subtotal resection, spinal canal decompression and titanium cage packed with autologous cancel ous bone and pedicle screw fixation. Imaging examination was performed before and after treatment to observe the recovery of vertebral sequence, vertebral height and Cobb angle, as wel as the recovery of nerve function. RESUTLS AND CONCLUSION:The patients were fol owed-up for 12 months, and al the patients healed wel after treated with titanium cage packed with autologous cancel ous bone and pedicle screw fixation, and there was no loosening, shedding or breakage after pedicle screw fixation. During reexamination, the grafts fusion, good deformity correction, basic recovery of vertebral height and good recovery of Cobb angle were observed. Seven cases had neurological function recovery, and among them, six cases raised for one degree, one case raised for two degrees, and another 22 cases without recovery. Case analysis and relative researches showed that subtotal resection and decompression and titanium cage packed with autologous cancel ous bone and pedicle screw fixation can reduce the loss of correction of the patients with thoracolumbar fracture and dislocation, restore the vertebral height, and enhance the stability of the vertebral body.
