To measure lateral and medial tibial plateau angle values in isolated canine tibiae and to compare lateral and medial tibial plateau angle values between dogs based on sex and breed.
Tibiae of 90 dogs from 24 different breeds were used. Photographs were taken of the medial and lateral aspects of the tibiae for measurement of the medial and lateral tibial plateau angles. Additionally, the medial tibial plateau angle was measured from radiographs of the tibiae. Two-way analysis of variance was used to test the effects of side, sex and breed on the medial and lateral tibial plateau angles as measured from photographs as well as the medial tibial plateal angles as measured from radiographs. The photographic and radiographic medial tibial plateau angles were compared by paired t-test, whereas the medial and lateral photographic tibial plateau angles were compared by t-test.
When all dogs were included in the analysis, the difference between the mean medial tibial plateau angle (24.0 ± 3.19°) and the mean lateral tibial plateau angle (25.5 ± 3.84°) as measured from photographs was significant (p <0.05). The difference in the photographic medial tibial plateau angle between male and female dogs was significant (p <0.05), whereas the difference in the photographic lateral tibial plateau angle between sexes was not significant. There was a significant difference between the medial and lateral tibial plateau angles as measured from photographs in male dogs (p <0.05) but not in female dogs. Breed comparisons also showed significant differences for the photographic lateral tibial plateau angle (p <0.05).
The axial rotation of the femoral condyles on the tibial plateau is probably affected by the discrepancy between the medial and lateral tibial plateau angles, and this difference in certain breeds might influence the prevalence of cranial cruciate ligament disease.
测量离体犬胫骨的内外侧平台角值，并根据性别和品种比较犬之间的内外侧平台角值。
使用来自24个不同品种的90只犬的胫骨。拍摄胫骨的内外侧照片以测量内外侧平台角。此外，从胫骨的X光片测量内侧平台角。采用双向方差分析来测试侧面、性别和品种对从照片测量的内外侧平台角以及从X光片测量的内侧平台角的影响。通过配对t检验比较照片测量和X光片测量的内侧平台角，而通过t检验比较照片测量的内外侧平台角。
当所有犬都纳入分析时，从照片测量的平均内侧平台角（24.0±3.19°）和平均外侧平台角（25.5±3.84°）之间的差异具有统计学意义（p<0.05）。公犬和母犬之间照片测量的内侧平台角差异具有统计学意义（p<0.05），而两性之间照片测量的外侧平台角差异无统计学意义。公犬照片测量的内外侧平台角之间存在显著差异（p<0.05），而母犬则无。品种比较也显示照片测量的外侧平台角存在显著差异（p<0.05）。
股骨髁在胫骨平台上的轴向旋转可能受内外侧平台角差异的影响，某些品种的这种差异可能影响颅交叉韧带疾病的患病率。
