MORPHOMETRIC STUDY OF THE MEDIAL COLLATERAL AND OBLIQUE LIGAMENTS OF THE ELBOW JOINT OF THE DOG (Canis familiaris)
The objective of the present study was to describe the sites of insertion of the medial collateral and oblique ligaments of the cubital joint of the dog and to evaluate their morphometry, in addition to the bones (humerus, radius and ulna) involved in the joint. The study was conducted on 20 adult d...

| Sumario: | The objective of the present study was to describe the sites of insertion of the medial collateral and oblique ligaments of the cubital joint of the dog and to evaluate their morphometry, in addition to the bones (humerus, radius and ulna) involved in the joint. The study was conducted on 20 adult dogs (10 males and 10 females). The distal part of the medial collateral ligament is divided into cranial and caudal portions, with the caudal portion being long and narrow, with a mean length of 3.30 ± 0.36 cm and a mean width of 0.26 ± 0.06 cm. This portion penetrates the interosseous space and attaches to the proximal caudolateral surface of the radius. The oblique ligament is capsular, with a mean length of 2.94 ± 0.30 cm and a mean width of 0.28 ± 0.08 cm and caudally is also divided into cranial and caudal portions, with the former attaching to the proximal medial border of the radius, bypassing the tendons of insertion of the brachial muscle and biceps brachii muscle. The cranial portion of the medial collateral ligament and the caudal portion of the oblique ligament fuse together, representing a region that acts as a reinforcement for adjacent ligament structures. |
