“…This incongruence occurs because of loss of cartilage at the center of the trochlear notch and it may represent a physiologic response to the lack of loading in this region. Loss of the cartilage in the center of the trochlear notch in dogs is correlated with higher body weight and is common in large and giant breeds, yet not observed in chondrodystrophoid breeds 25 . We only found 1 case of humero‐ulnar incongruence because of abnormal trochlear notch and it was in a Labrador.…”

“…Snaps and colleagues 5,6 published an MR protocol to evaluate the canine elbow joint and provided a brief description of the normal anatomy. Other reports describe the bony structure of the elbow and the relation to elbow dysplasia 7,8 . Several reports note presence of mineralization in the soft tissues at the level of the medial or lateral epicondyle of the humerus that can be associated with elbow dysplasia 9–12 .…”

“…These facts could be explained by the bicentric transmission of loads exhibited by some individuals reported in previous biomechanical studies (Preston et al, ). This phenomenon seems to optimize stress distribution and is even more evident in heavier dogs of large and giant breeds (Breit et al, ; Janach et al, ). An increased subchondral bone density was also reported at the anconeal process and medial coronoid process (Dickomeit et al, ).…”

Assessing the ulnar trochlear notch (UTN) radiographic anatomy has been considered important, but difficult, in the diagnosis of elbow dysplasia. The purpose of this study was to evaluate UTN curvature of natural elbows in radiographs, using a methodology applied to disarticulated joints. The methodology was implemented and validated using dedicated software created by the authors. Mediolateral extended (MLE) and mediolateral flexed (MLF) elbow views were used from 20 joints from canine cadavers that were over 20 kg. After arranging the bones to avoid radiographic overlapping of the bones, an additional mediolateral radioulnar (MLRU) view was made. Curvature radius measurements from the central ridge of the UTN of each elbow were acquired in the MLRU view, using the software. The measurements were repeated in a second session, to determine repeatability. Then similar UTN measurements were taken from the MLE and MLF views, to determine reproducibility. Intraclass correlation coefficient (ICC) for repeatability and reproducibility of measurements were above 0.98 (95% confidence interval limits >0.75). The 95% limits of agreement (LA) for repeatability were 22.98 to 3.19 mm. The 95% LA for reproducibility between MLRU and MLE views were 24.32 to 3.75 mm. The 95% LA for reproducibility between MLRU and MLF views were 25.02 to 4.07 mm. The methodology and software are determined to be both precise and suitable to evaluate the UTN in MLE and MLF elbow views of large breed dogs, for anatomical and clinical purposes. In the future it would be useful to characterize normal and dysplasAbbreviations used: CI 5 confidence interval; ICC 5 intraclass correlation coefficient; LA 5 limits of agreement; MLE 5 mediolateral extended elbow view; MLF 5 mediolateral flexed elbow view; MLRU 5 additional mediolateral radioulnar view; MLRU 1 5 second session of measurements in the MLRU view; SD 5 standard deviation; SEM 5 standard error of the mean; UTN 5 ulnar trochlear notch; d 5 mean difference; f 0 5 first derivative of the polynomial fit to the points; q 5 Radii of curvature; r 2 5 correlation coefficient; s* 5 normalized natural coordinate; f 00 5 second derivative of the polynomial fit to the points.
