Radiographic myelography measurements in 22 horses undergoing cervical interbody fusion

This data set describes measurements of dural diameter and dorsal contrast column height in 22 horses at five cervicocervical articulations (C2-3, C3-4, C4-5, C5-6 and C6-7) in three neck positions (neutral, flexed, extended) derived from radiographic myelography with measurements made independently by three masked observers (EM, LN, DE listed above). It also describes changes in articular process joint height and area from before to years after surgery in nine horses at a total of 13 operated sites. This data was collected to determine how well the two measures correlated with each other, and with historically operated surgical sites in these horses. In addition, to determine if surgery generated any substantial reduction in articular process joint height and area on radiographs obtained many years after surgery in nine horses.

本数据集包含两类测量数据：其一为22匹马在3种颈部体位（中立位、屈曲位、伸展位）下，于5处颈椎间关节（C2-3、C3-4、C4-5、C5-6及C6-7）处的硬脊膜直径（dural diameter）与背侧造影柱高度（dorsal contrast column height）测量结果，该数据源自X线脊髓造影术（radiographic myelography），且由3名盲法评估者（masked observers，EM、LN、DE见前文）独立完成；其二为9匹马共13处手术部位在术前至术后多年的关节突关节（articular process joint）高度与面积变化情况。本数据集的采集旨在明确上述两项核心测量指标间的相关性，以及这些指标与受试马匹既往手术部位的关联程度；此外还旨在探究，在术后多年获取的X线影像中，手术是否会对关节突关节的高度与面积造成显著降低。
