Anatomical study of fibrous structures of the medial aspect of the canine elbow joint

Abstract

Forces exerted by fibrous structures on the medial aspect of the canine elbow joint have been reported to be involved in elbow pathology. The purpose of this paper is to assess the relationships of the ligamentous and muscular structures of this region of the canine elbow joint, and how they relate to the medial coronoid process. Six cadavers of adult German shepherd cross-breed dogs were used in this study to make intra-articular and vascular injections of this region. Some joints were dissected and some were frozen to saw sagittal or dorsal cryosections to assess the relationships of the myotendinous structures. The brachialis muscle tendon passed through the division of the bicipital tendon of insertion which formed a fibrous tendon sheath that was reinforced by the oblique ligament. The biceps' brachii's main insertion is the radial tuberosity where it inserts along with the cranial branch of the oblique ligament and the cranial branch of the medial collateral ligament. Rotational and compression forces exerted by the insertion of the biceps brachii-brachialis tendon complex onto the ulna might influence medial coronoid disease. Therefore, sectioning these tendons could be considered as a treatment for medial coronoid disease.

E12 sheet plastination: Techniques and applications

“…Villamonte‐Chevalier et al (, ) studied the elbow joint in the dog, correlating ultrasound images with transparent plastinated anatomical sections. Soler et al () studied the stifle joint in dogs with sheet plastination, comparing the results with ultrasonography, computed tomography and magnetic resonance images.…”

E12 technique: Conventional epoxy resin sheet plastination

“…In diagnostic imaging techniques, such as CT or MRI, E12 plastinated sections have been used as a basis for the correct identification of anatomical structures in the same planes used in imaging techniques. Some examples of these studies are those made in the tarsus (Latorre et al, ), elbow (Villamonte‐Chevalier et al, ; Villamonte‐Chevalier, Soler, Sarria, Agut, & Latorre, ) and temporomandibular joint (Arredondo, Agul, Rodríguez, Sarriá, & Latorre, ; Rodriguez, Agut, Gil, & Latorre, ; Rodriguez et al, , ).…”

Coronoiderkrankung des Ellbogengelenks beim Hund

“…Ein relativ kurzer Radius soll zu einer Überlastung des medialen Coronoids führen. ▪ die Insertion der Bizepssehne als Ursache einer abnormalen Belastung des Coronoids [4,5] Durch die bildgebenden Verfahren wie CT und Mikro-CT und die Histopathologie wurden Veränderungen in Struktur und Dichte des Coronoids beschrieben [6]. Die Coronoiderkrankung zeigt sich normalerweise als eine Pathologie des zentralen Teiles des medialen Coronoids, dort, wo Ulna und Radius das radioulnäre Gelenk bilden (▶ Abb.…”
