Abstract

Objective: This study aimed to examine relationships of the degree and level of spinal ankylosis with spinal mobility and functional impairment in patients with radiographic axial spondyloarthritis (r-axSpA) using computed tomography (CT).

Methods: This retrospective study involving 27 patients examined the number of fused intervertebral segments in the whole, cervical, thoracic, and lumbar spine using CT as a measure of spinal ankylosis, Bath Ankylosing Spondylitis Metrology Index (BASMI) as a measure of spinal mobility, and Bath Ankylosing Spondylitis Functional Index (BASFI) as a measure of functional impairment.

Results: Significant positive correlations were found between both BASMI and BASFI and the number of fused intervertebral segments in the whole, cervical, thoracic, and lumbar spine. 'Tragus to wall distance', a BASMI item, was significantly positively correlated with the number of intervertebral segments in the lumbar spine (r = 0.46, P = .02). 'Looking over your shoulder', a BASFI item, was strongly negatively correlated with the number of fused intervertebral segments in the cervical spine (r = 0.804, P < .01).

Conclusions: The number of fused intervertebral segments was associated with impaired spinal mobility and functional impairment. Impaired spinal motion and functional impairment in daily living varied depending on the level of spinal ankylosis.

脊柱强直与脊柱活动能力和影像学中轴性脊柱性关节炎功能损害的关联：一项计算机断层扫描研究。

研究目的本研究旨在通过计算机断层扫描（CT）检查放射性轴性脊柱关节炎（r-axSpA）患者脊柱强直的程度和水平与脊柱活动度和功能障碍的关系：这项涉及 27 名患者的回顾性研究使用 CT 作为脊柱强直的衡量标准，使用巴斯强直性脊柱炎计量指数（BASMI）作为脊柱活动度的衡量标准，使用巴斯强直性脊柱炎功能指数（BASFI）作为功能障碍的衡量标准，检查了整个脊柱、颈椎、胸椎和腰椎中融合的椎间节段数量：结果：BASMI 和 BASFI 与整个脊柱、颈椎、胸椎和腰椎的椎间融合节段数均呈显著正相关。BASMI 中的 "肚脐到墙壁的距离 "与腰椎的椎节数目呈显著正相关（r=0.46，p=0.02）。BASFI项目中的 "向肩上看 "与颈椎椎间融合节段数呈强烈负相关（r=0.804，p结论：椎间融合节段的数量与脊柱活动度受损和功能障碍有关。脊柱活动度受损和日常生活功能障碍因脊柱强直程度而异。
