Spinal pseudoarthrosis is an uncommon complication in patients with advanced ankylosing spondylitis which consists in destruction of the discovertebral junction. Two cases of spinal pseudoarthrosis at the thoracolumbar level after a spontaneous fall are reported. Because of the neural arch involvement and the spinal cord compression a stabilization was required. Different imaging techniques are complementaries in the study of this entity, conventional radiographs and computed tomography may depicte bone abnormalities, but magnetic resonance allows a correct evaluation of spinal cord and soft tissue involvement.
脊柱假关节形成是晚期强直性脊柱炎患者中一种罕见的并发症，其特征是椎间盘连接部位遭到破坏。本文报告了两例因自发性跌倒后发生胸腰段脊柱假关节形成的病例。由于神经弓受累及脊髓受压，需要进行稳定手术。不同的影像学技术在该疾病的研究中互为补充，传统X线片和计算机断层扫描可显示骨骼异常，但磁共振成像能正确评估脊髓和软组织受累情况。
