Abstract: Objective To investigate the effects of short-segment pedicle screws system on type A thoracic and lumbar spine fracture with or without pedicle screws on the fractured level. Methods 23 patients with type A thoracic and lumbar spine fracture were included, in which 11 cases received traditional short-segment pedicle screws system without pedicle screws on the fractured level (group A), and other 12 cases with pedicle screws on the fractured level (group B). The anterior vertebral height, posterior vertebral height and local kyphosis an-gle were measured before and after operation. Results All pedicle screws were successfully implanted with good location and stability. The vertebral height and kyphosis angle significantly improved after operation in both groups (P<0.05), and the improvement of kyphosis angle was more in group B than in group A (P<0.05). Conclusion Short-segment pedicle screws system with pedicle screws on the fractured level may fine correct the kyphosis angle in short term.
