METHODS: Radiographs of the thoracolumbar spine of healthy horses (N = 100) were assessed by three observers. Spinous processes were separately graded for interspinous space width, modelling, radiopacities, radiolucencies and isolated opacities dorsally. Inter- and intra-observer agreement was assessed for individual and combinations of parameters.
RESULTS: Agreement (inter- and intra-observer) was good for the following parameters: interspinous space width, isolated opacities dorsally, beak-shaped formations craniodorsally and modelling cranioventrally. The agreement increased slightly for a sum of specific parameters such as radiopacities, modelling, dorsal abnormalities and related abnormalities involving increased opacity, modelling and osseous cyst-like lesions. Agreement for the total radiographic abnormalities per back was moderate.
CONCLUSIONS: Grading of thoracolumbar radiographs in horses without back pain showed good inter- and intra-observer agreement for specific parameters and these should be used in future grading of spinous processes. Limitations should be considered in pre-purchase examinations.
方法:由三名观察者评估了健康马(N=100)的胸腰椎的X射线照片。棘突的棘突间隙宽度分别分级,建模,射线不透明性,背面的具放射性和孤立的混浊。评估了个体和参数组合的观察者之间和观察者之间的一致性。
结果:协议(观察者间和观察者内)对以下参数良好:棘突间间隙宽度,背部孤立的混浊,喙形的颅骨和颅骨模型。该协议对特定参数的总和略有增加,例如放射性,建模,背侧异常和涉及混浊增加的相关异常,建模和骨囊肿样病变。每个背部的总射线照相异常的一致性是中等的。
结论:对无背痛的马进行胸腰段X线片的分级显示,对于具体参数,观察者之间和观察者之间的一致性良好,这些参数应用于未来的棘突分级。在购买前检查中应考虑限制。
