Clinical, radiographic and scintigraphic signs associated with spondylosis of the equine thoracolumbar spine have been poorly documented.
To establish an objective radiographic and scintigraphic grading system for spondylosis lesions; to estimate the prevalence of spondylosis in a population of horses with back pain; and to compare the results of radiography and scintigraphy.
Radiographic images of the thoracolumbar spine from 670 horses with clinical signs of back pain were graded. Scintigraphic images from horses with spondylosis lesions underwent subjective and objective analysis. Sensitivity and specificity of scintigraphy for detection of spondylosis relative to radiography for identification of spondylosis were calculated, and Chi-squared analysis was performed to test for an association between location and severity of lesions.
Twenty-three of 670 horses (3.4%) with back pain had radiographic evidence of spondylosis. Of these horses, 14 (61%) had more than one lesion and 44% (n=22) of lesions occurred between T11-T13 vertebral bodies. Only 33% (n=28) of locations with radiographic changes had increased radiopharmaceutical uptake.
Spondylosis occurs at a low prevalence in horses with back pain. It may be present alone or in association with other osseous abnormalities. The clinical significance of spondylosis needs further investigation.
Spondylosis is uncommon but may be a contributor to back pain in the horse.
与马的胸腰椎脊柱骨关节炎相关的临床、放射学和闪烁扫描迹象记录不佳。
建立一个用于脊柱关节炎病变的客观放射学和闪烁扫描分级系统；评估在一群有背痛的马中脊柱关节炎的流行率；并比较放射学和闪烁扫描的结果。
对 670 匹有背痛临床症状的马的胸腰椎脊柱进行放射影像学分级。对有脊柱关节炎病变的马的闪烁扫描图像进行主观和客观分析。计算闪烁扫描相对于放射学对检测脊柱关节炎的敏感性和特异性，进行卡方分析以检验病变位置和严重程度之间的关联。
670 匹有背痛的马中有 23 匹（3.4%）有放射学证据表明存在脊柱关节炎。这些马中，14 匹（61%）有一个以上的病变，44%（n=22）的病变发生在 T11-T13 椎体之间。只有 33%（n=28）的放射学改变部位有放射性药物摄取增加。
在有背痛的马中，脊柱关节炎的发生率较低。它可能单独存在，也可能与其他骨骼异常并存。脊柱关节炎的临床意义需要进一步研究。
脊柱关节炎不常见，但可能是马背痛的一个原因。
