Objectives To compare elbow congruity in two cohorts of Labrador retrievers affected with either radial incisure or apex fragmentation of the medial coronoid process. Materials and Methods Dogs were included if they had elbow lameness and a CT diagnosis of a fissure or fragmentation of the medial coronoid process occurring either along the radial incisure or at the coronoid apex. Radioulnar joint space was measured incrementally from the lateral to the medial coronoid process on transverse slice images. Axial radioulnar congruency was also measured at the apex and mid‐coronoid in the dorsal plane and at the base of the coronoid in the sagittal plane. Results We studied 99 elbows (in 66 dogs) of which 56 had a fissure or fragmentation along the radial incisure and 43 had an apical fragment. No difference was found between the two groups at the different measuring points – with the exception of a transverse plane radioulnar joint space measurement in the radial incisure group that was smaller adjacent to the lateral coronoid process. Clinical Significance Abnormal ulnar morphology in the radial incisure group could result in a fulcrum effect within the radioulnar joint, overloading the radial incisure and predisposing to osteochondral damage at this site.

“…The presence of medial coronoid disease of the canine elbow with concurrent widespread medial joint compartment osteoarthritis (OA) is often referred to as medial compartment disease (MCD) . The severe cartilage erosions that occur with MCD in the presence of apparently healthy joint surfaces of the lateral joint compartment have led some authors to draw similarities between canine MCD and medial knee gonarthrosis in people .…”

“…In particular, this would redirect the orientation of the medial collateral ligament, lateral collateral ligament, and the oblique ligament. The pull mechanism of the brachialis and biceps brachii muscles would also be affected as noted by Fitzpatrick et al In the recent in vivo study of the elbows of dogs with MCD by Rohwedder et al, the humerus showed a distinct internal‐external rotational motion . Although the authors considered the motion a result of ligamentous laxity, an alternative mechanism might also be possible.…”

“…Computed tomography sets from both groups included a scan of the antebrachium from the distal one‐third of the humerus to the middle of the metacarpal bones. All animals in the study group had signs of MCD, including FMCP, subchondral sclerosis of the MCP, osteochondrosis of the medial humeral condyle, and different degrees of osteophyte formation . Some of the dogs also had various degrees of radioulnar incongruity, as estimated by the attending radiologist from CT and radiographic images.…”

Objective To evaluate the magnitude and direction of radial torsion (RT) in dogs with medial compartment disease (MCD). Study design Case‐control study. Sample population Twenty‐eight healthy dogs and 28 dogs with confirmed MCD. Methods Computed tomography images of each dog's antebrachium were evaluated. Radial torsion was measured by using previously described landmarks on the proximal and distal radius. Differences between groups were tested with Student's t tests and Wilcoxon rank‐sum tests. Results Healthy dogs had a mean RT angle of 3.44° (range, 1.28°‐5.44°). Dogs with MCD had a mean RT angle of 11.84° (range, 2.31°‐26.55°). Both groups included similar proportions of dogs with external (76% vs 77%) and internal (24% vs 23%) torsion. The direction of torsion (P = .21 and P = .69) did not appear to affect the magnitude of the RT angle. Conclusion Dogs with MCD had an increased RT angle compared with healthy controls. The direction of torsion varied similarly between groups regardless of the disease status of dogs in this study. Clinical significance The fourfold increase in the RT seen in dogs with MCD may contribute to the rotational overload proposed recently, potentially modifying the orientation of the elliptical radial head and the ligaments crossing the elbow joint.
