Abstract:

BACKGROUND: Posterior short segment pedicle screw fixation devices can achieve similar anatomic fracture reduction effect and significantly improve the outcome, but the loss of orthopedic degree during long-term follow-ups, fixation failure and other complications are commonly seen.
OBJECTIVE: To study the feasibility and curative effect of posterior transpedicular pedicle screw fixation and bone graft for thoracolumbar fractures.
METHODS: Seventy-three thoracolumbar vertebra fracture patients treated by unilateral pedicle screw fixation and contralateral autologous and allogeneic bone graft.
RESULTS AND CONCLUSION: All the patients achieved bone union within 6 months, and the fusion rate was 100%. No screw loosening and breaking occurred. One case of Frankel grade C had no change, and 1 case of Frankel grade D had no change. The remaining patients had an improvement in neurologic function and low back pain; The Cobb angle of the injured segment, the height of anterior border of the injured vertebral body and the vestigial degree of canalis spinalis anteroposterior diameter were significantly restored with 6 months after treatment. Vertebral pedicle screw fixation with transpedicular bone graft cannot only reduce verbebral fracture satisfactorily, reconstruct thoracolumbar height, increase the stability of the spine, but also decrease the possibility of nail breaking and correction loss.
