To describe the radiographic, computed tomographic (CT), and arthroscopic findings in different age groups of Labrador Retrievers diagnosed with medial coronoid disease (MCD), and to compare the ulnar subtrochlear sclerosis (STS) observed on radiographs with the ratio between the mean attenuation of the ulnar subtrochlear bone and the mean attenuation of the cortical bone measured on CT.
Prospective clinical study.
Dogs (n = 31; 31 elbow joints) and 6 healthy Labrador Retrievers (6 elbow joints).
Radiographic, CT, and intraoperative arthroscopic images (2008-2012) were evaluated. Statistical analysis was performed for the descriptive study to evaluate the difference in findings between age groups and to investigate the correlation between radiographic and CT evaluated ulnar STS.
Ulnar STS (87.6%) was the most common radiographic findings in dogs ≤12 months and blurring of the cranial edge of the medial coronoid process (MCP; 66.7%) was the most common radiographic findings in dogs >12 months. MCP fragmentation was the most common CT finding in both age groups (93.8% [≤12 months]; 66.7% [>12 months]). A displaced fragment (68.8%) was the most common arthroscopic finding in dogs ≤12 months whereas osteochondromalacia (53.3%) was the most common finding in dogs >12 months. Sensitivity of radiography in detecting MCD was 93.8% (≤12 months) and 73.3% (>12 months) and for CT was 93.8% (≤12 months) and 66.7% (>12 months). Radiographic evaluated ulnar STS was strongly correlated with CT evaluated ulnar STS.
Wide ranges of radiographic, CT, and arthroscopic findings in Labrador Retrievers diagnosed with medial coronoid disease were identified.
描述诊断为内侧冠状突疾病（MCD）的不同年龄组拉布拉多寻回犬的X线、计算机断层扫描（CT）和关节镜检查结果，并比较X线片上观察到的尺骨滑车下硬化（STS）与CT测量的尺骨滑车下骨平均衰减与皮质骨平均衰减的比值。
前瞻性临床研究。
犬（n = 31；31个肘关节）和6只健康拉布拉多寻回犬（6个肘关节）。
评估X线、CT和术中关节镜图像（2008 - 2012年）。对描述性研究进行统计分析，以评估年龄组之间检查结果的差异，并研究X线和CT评估的尺骨STS之间的相关性。
尺骨STS（87.6%）是12个月及以下犬最常见的X线表现，而内侧冠状突（MCP）前缘模糊（66.7%）是12个月以上犬最常见的X线表现。MCP碎裂是两个年龄组最常见的CT表现（12个月及以下为93.8%；12个月以上为66.7%）。移位碎片（68.8%）是12个月及以下犬最常见的关节镜表现，而骨软骨软化（53.3%）是12个月以上犬最常见的表现。X线检查检测MCD的敏感性在12个月及以下犬为93.8%，12个月以上犬为73.3%；CT检测的敏感性在12个月及以下犬为93.8%，12个月以上犬为66.7%。X线评估的尺骨STS与CT评估的尺骨STS密切相关。
确定了诊断为内侧冠状突疾病的拉布拉多寻回犬在X线、CT和关节镜检查方面存在广泛的表现。
