Abstract

In part one of this project, the use of reconstructed computed tomography (rCT) for the investigation of elbow joint surface incongruency was validated using 12 cadaver elbows. Following gross clinical and radiographic examinations which excluded any obvious elbow pathology, the elbows were scanned in pairs in the same computed tomography (CT) scanner. From these scans, standardised frontal and sagittal plane images were reconstructed using medical image analysis software (Omnipro, California, USA). From the reconstructions, humeroradial (HR) and humerulnar (HU) joint spaces were measured from both frontal (giving FrHR and FrHU values) and sagittal (giving SagHR and SagHU values) plane images. In part two of this project, a retrospective study was undertaken to evaluate elbow joint congruency in dogs suffering coronoid process disease. Based on clinical, radiographic and transverse CT examinations, elbows were divided into control or coronoid disease (CD) groups. Standardised rCT images were formatted in the frontal and sagittal planes. HR and HU measurements were obtained from the images and incongruencies calculated by comparing the two measurements. 42 CD and 29 control elbows were identified. No incongruencies were noted at the coronoid base. At the level of the coronoid apex, CD elbows exhibited a significant radioulnar incongruency compared to controls (p<0.0001). Comparing CD and control elbows at the level of the apex, the HR joint space was increased in CD elbows (p=0.0006) whereas no difference was noted in the HU space. Part two of this study supports the hypothesis that joint incongruency is associated with coronoid disease in dogs. However, the precise mechanism of development of this incongruency could not be determined from the data. (Abstract shortened by ProQuest.).
