Musculoskeletal Anatomy

This study characterized the normal musculoskeletal anatomy of the cervical segment of the spine of dogs by means of B-mode ultrasonography. The objective was to establish the role of B-mode ultrasonography for the anatomical evaluation of the cervical spine segment in dogs, by comparing the ultrasonographic findings with images by computed tomography and magnetic resonance imaging. The ultrasound examination, in transverse and median sagittal sections, allowed to identify a part of the epaxial cervical musculature, the bone surface of the cervical vertebrae and parts of the spinal cord through restricted areas with natural acoustic windows, such as between the atlanto-occipital joint, axis and atlas, and axis and the third cervical vertebra. The images, on transverse and sagittal planes, by low-field magnetic resonance imaging, were superior for the anatomical identification of the structures, due to higher contrast between the different tissues in this modality. Computed tomography showed superiority for bone detailing when compared with ultrasonography. As for magnetic resonance imaging, in addition to the muscles and cervical vertebrae, it is possible to identify the cerebrospinal fluid and differentiate between the nucleus pulposus and annulus fibrosus of the intervertebral discs. Although not the scope of this study, with knowledge of the ultrasonographic anatomy of this region, it is believed that some lesions can be identified, yet in a limited manner, when compared with the information obtained mainly with magnetic resonance imaging. The ultrasound examination presented lower morphology diagnostic value compared with the other modalities.

Aim. Evaluation of the role of vascular remodeling in the formation of structural phenotypes of osteoarthritis (OA).Materials and methods. 62 patients with OA aged 65,9±8,8 years and 18 volunteers without clinical and roentgenologic signs of OA aged 60,7±7,9 years were examined. All patients underwent magnetic resonance imaging of knee joints. To analyze the structural changes in the tissues of the knee joint, the WORMS protocol was used for magnetic resonance imaging. The thickness of the vascular wall, the external diameter, the vascular index (VI) were measured – the ratio of the diameter of the lumen of the vessel to the thickness of the popliteal artery (PA) wall, the branch of the upper lateral artery (LA), the medial artery of the knee (MA).Results. The analysis of the parameters of the arteries of the knee joint showed that with a subchondral OA phenotype, the thickness of the PA wall is statistically significantly larger than the cartilage phenotype, and the vascular index of the PA is significantly higher in the group of the cartilaginous phenotype. The upper LA wall was significantly thicker in the subchondral OA phenotype. VI of the upper LA was significantly lower in patients with a subchondral phenotype compared with the cartilaginous phenotype. The thickness of the MA wall was also larger with a bone phenotype, and VI with a cartilaginous phenotype.Conclusion. The results of the study showed the relationship between vascular remodeling and structural progression of OA. Changes in the vascular wall adversely affect all joint tissues, leading to their remodeling. It was established that the degree of vascular remodeling determines the formation of structural OA phenotypes. Severe vascular changes are associated with the subchondral OA phenotype.
