Ankylosing spondylitis is a seronegative spondyloarthropathy which predominantly affects the sacroiliac joints and the spine. The spine can become very kyphotic with time. Minor trauma is sufficient to produce a fracture, because of the underlying osteoporosis and because the ankylosed segments constitute large leverage arms. These fractures are unstable because the soft tissues are ossified and also involved in the fracture. Cervical spine fractures need an immobilisation which respects the pre-injury flexion deformity. Inadvertent application of a rigid collar which forces the previously flexed cervical spine into extension may lead to neurological deterioration and even death. We report such a case in a 59-year-old male patient.
强直性脊柱炎是一种血清阴性脊柱关节病，主要影响骶髂关节和脊柱。随着时间推移，脊柱会变得严重后凸。由于存在潜在的骨质疏松症，且强直的节段构成了较大的杠杆臂，轻微创伤就足以导致骨折。这些骨折不稳定，因为软组织已骨化且也参与了骨折。颈椎骨折需要固定，同时要考虑到受伤前的屈曲畸形。不小心使用硬领迫使先前屈曲的颈椎伸展，可能会导致神经功能恶化甚至死亡。我们报告了一名59岁男性患者的此类病例。
