Bicipital Tenosynovitis, Brachii Muscle Rupture, and Supraspinatus Avulsion in Dogs
The shoulder joint is a “ball-and-socket” joint. In four legged animals it is made up of the scapula/shoulder blade bones, and the humerus/upper bone of the front leg. These bones are supported by ligaments and tendons. A ligament is a band of connective or fibrous tissue that connects two bones or cartilage at a joint, and a tendon is a band of connective or fibrous tissue that connects a muscle to a bone.
Shoulder-joint ligament and tendon conditions make up the majority of causes for lameness in the canine shoulder joint, excluding osteochondritis dissecans (a condition characterized by abnormal development of bone and cartilage, leading to a flap of cartilage within the joint). It is a disease that occurs in medium to large-breed dogs when they become skeletally mature, around one year of age or older. The average age for development of this condition is between 3 to 7 years of age.
