Facet dislocation is a rare finding in the thoracic spine. This article presents three cases of bilateral locked facets in the thoracic region. Two were due to car accidents and the third was secondary to a vertical fall. The level of the injury was T2-T3 in two cases and T9-T10 in the third. Two patients were completely paraplegic on admission, whereas the third was neurologically intact. All patients had various associated injuries and fractures. The diagnosis of locked facets was not suspected in any of the cases, but was later made by computerized tomography with parasagittal reconstructions. All patients underwent surgery. The radiological diagnosis was confirmed intraoperatively in two cases. The facets were relocated by manual traction in one case and by Harrington distraction in the other. Fixation and fusion were performed in all three. Stability and vertebral alignment were achieved in all cases postoperatively.
小关节脱位在胸椎中是一种罕见的情况。本文介绍了3例胸椎双侧小关节交锁的病例。其中2例由车祸导致，第3例继发于垂直坠落。2例损伤节段为T2 - T3，第3例为T9 - T10。2例患者入院时完全截瘫，而第3例神经功能完好。所有患者均有各种合并伤和骨折。所有病例最初均未怀疑小关节交锁，而是后来通过矢状旁重建的计算机断层扫描确诊。所有患者均接受了手术。2例术中证实了影像学诊断。1例通过手法牵引复位小关节，另1例通过哈林顿撑开器复位。3例均进行了固定和融合。术后所有病例均实现了稳定性和椎体对线。
