“…Developmental elbow disease is one of the most frequent causes of front limb lameness especially in young dogs, being bilateral in up to 35% (Kirberger and Fourie, 1998;Morgan et al, 1999). Radio-ulnar incongruence (RUI) has been reported to occur concomitant to medial coronoid disease in up to 60% of clinical cases and has been shown to be related to the severity of medial compartment pathology (Eljack and Bottcher, 2015).…”

Aim of the study was to investigate dynamic radio-ulnar incongruence (dRUI) in the canine elbow joint comparing orthopedic healthy and dysplastic dogs in a prospective in vivo study design. In 6 orthopedic sound elbow joints (5 dogs, median age 17 months & mean body weight 27.9 kg) and 7 elbow joints with medial coronoid disease (6 dogs, median age 17.5 months & mean body weight 27.6 kg) 0.8 mm Ø tantalum beads were surgically implanted into radius, ulna and humerus for dynamic radiosteriometric analysis (RSA) using high-speed biplanar fluoroscopy with the dogs walking on a treadmill. dRUI, in the form of proximo-distal translation of the radius relative to the ulna, was measured for the first third of stance phase and compared between groups using unpaired t-testing. Healthy elbow joints exhibited a relative radio-ulnar translation of 0.7 mm (SD 0.31 mm), while dysplastic joints showed a translation of 0.5 mm (SD 0.30 mm). No significant difference between groups was detected (p = 0.2092, confidence interval -0.6 -0.2). Based on these findings dRUI is present in every canine elbow joint, as part of the physiological kinematic pattern. However, dysplastic elbow joints do not show an increased radio-ulnar translation, and therfore dRUI cannot be considered causative for medial coronoid disease.

“…A prevalence of 3.7% was reported in a large cohort of Labrador retrievers in the U.S. in the late 1990s (Morgan et al, 1999). For the Bernese mountain dog, a prevalence of 1.9% was published in a large study in Germany (Hartmann, 2010).…”

“…Small breeds are less likely affected (Bruggeman et al, 2010). So far, prevalences of OC in the canine shoulder joint have been reported only for breeds in Belgium and the US (Coopman et al, 2008;Morgan et al, 1999). Occurrence of OC is more common in the shoulder joint than in other joints and often occurs bilateral.…”

Osteochondrosis (OC) is common in large-breed dogs. According to the breeding guidelines of the Swiss kennel clubs, the shoulder joints are included in the radiographic screening for joint diseases in the Greater Swiss Mountain dog (GSMD) and the Border Collie (BC) since 1993 and 2003, respectively. The aim of this study was to estimate the overall prevalence of humeral head OC in these 2 breeds in Switzerland based on the data of the Swiss National Dysplasia Committees. All radiographs were reevaluated to assess single radiographic changes. From 1993From and 2003From , accordingly, until 2013, the overall prevalence was 14% for the GSMD and 8% for the BC, respectively. Affected joints showed a focally reduced opacity or a flattened/indented contour of the caudal section of the humeral head. Articular flaps were only seen occasionally. Degenerative joint disease was significantly more common in OC affected joints (GSMD: 32%; BC: 20%) than in joints without OC. The present study is the first report on the prevalence of humeral head OC in a large cohort of GSMD and the BC over a long study period. In comparison to other breeds, the herein reported prevalences are in the mid to upper range. Results of the present study should alert veterinarians to the disease in these breeds and may serve as a starting point for further epidemiological and genetic studies.

“…However, FCP has also been found in small breeds of dogs and mongrels (Boulay 1998). Males are affected more often than females (Read et al 1990;Grøndalen and Lingas 1991;Huibregste et al 1994;Morgan et al 1999;Kirberger and Stander 2007). The disease is usually bilateral, while it may be clinically manifested only in one extremity (Grøndalen 1982;Olsson 1983).…”

Occurrence of Radiologically Detectable “Kissing” Lesion in Dog Elbows in Dependence on the Type of Fragmentation of the Processus Coronoideus Medialis and on Sex

et al. 2010

The aim of the study was to find the frequency of radiologically detectable "kissing" lesion in individual variants of fragmented processus coronoideus medialis (FCP) and its occurrence in relation to sex. The radiographs of elbow joints (n = 135) of dogs (n = 77) in which a fragmented processus coronoideus medialis ulnae was detected arthroscopically (n = 109) or arthrotomically (n = 26) were evaluated. Significantly higher occurrence of radiologically detectable "kissing" lesion was found in elbows with non-dislocated and dislocated fragment (p < 0.01). Significantly lower occurrence of radiologically detectable "kissing" lesion was found in elbows with chondromalacia of processus coronoideus medialis (PCM) (p < 0.01). We found no significant difference (p > 0.05) between the occurrence of a "kissing" lesion in males and females with FCP. The occurrence of the "kissing" lesion extending to the subchondral bone was not affected by sex. The results of our study suggest the possibility of identifying elbow joints with completely fragmented FCP on the basis of occurrence of a radiologically detectable "kissing" lesion.
