目的：探讨跨伤椎置钉和经伤椎置钉治疗A型胸腰椎骨折的手术效果。方法胸腰椎骨折行后路椎弓根系统内固定术治疗患者23例，按手术方法分为A组(跨伤椎置钉组)11例和B组(经伤椎置钉组)12例。手术前后测量伤椎前缘高度、伤椎后缘高度、局部后凸角。结果所有椎弓根螺钉均顺利植入，螺钉位置及内固定稳定性良好。两组椎体高度和后凸角均改善(P<0.05)，B组后凸角矫正程度优于A组(P<0.05)。结论后路椎弓根系统内固定结合经伤椎置钉，矫正后凸畸形的短期效果优于单纯内固定。

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.
