Thirty cubital joints from 16 dogs suspected of having a fragmented medial coronoid process were examined. Four breeds accounted for 87.5% of the cases: German Shepherd Dog (25%), Labrador Retriever (25%), Rottweiler (18.75%), and Golden Retriever (18.75%). Seventy-five percent of the dogs were male. Mean age of affected dogs was 13.6 months. Plain-film radiography, xeroradiography, linear tomography, arthrography, and computed tomography were performed on each cubital joint prior to surgical exploration of the joint. Three reviewers evaluated each diagnostic study and independently determined whether a fragment from the medial coronoid process could be seen. The consensus opinion was compared with the finding at surgery. Abnormalities of the medial coronoid process were detected in 25 of 30 joints at surgery. Fragmented coronoid process was found in 17 of 30 joints, and wear lesions were observed in 8 of 30 joints. Computed tomography had the highest accuracy (86.7%), sensitivity (88.2%), and negative-predictive value (84.6%) of the 5 imaging modalities evaluated (P < 0.05). Specificity and positive-predictive value of all imaging techniques were high. There was no significant difference between the diagnostic ability of plain-film radiography, xeroradiography, or linear tomography of the cubital joint. The combination of plain-film radiography and linear tomography provided an improvement in accuracy, approaching that of computed tomography.
对16只疑似患有内侧冠状突碎片的犬的30个肘关节进行了检查。4个品种占病例的87.5%：德国牧羊犬（25%）、拉布拉多寻回犬（25%）、罗威纳犬（18.75%）和金毛寻回犬（18.75%）。75%的犬为雄性。患犬的平均年龄为13.6个月。在对每个肘关节进行手术探查之前，对其进行了X线平片摄影、干板X线摄影、线性断层摄影、关节造影和计算机断层扫描。3名评估者对每项诊断研究进行评估，并独立确定是否能看到内侧冠状突的碎片。将共识意见与手术结果进行比较。手术中在30个关节中的25个发现了内侧冠状突异常。在30个关节中的17个发现了冠状突碎片，在30个关节中的8个观察到了磨损病变。在评估的5种成像方式中，计算机断层扫描的准确性（86.7%）、敏感性（88.2%）和阴性预测值（84.6%）最高（P<0.05）。所有成像技术的特异性和阳性预测值都很高。肘关节X线平片摄影、干板X线摄影或线性断层摄影的诊断能力之间没有显著差异。X线平片摄影和线性断层摄影的联合使用提高了准确性，接近计算机断层扫描的准确性。
