Supraspinatus Tendinopathy

Supraspinatus tendinopathy describes a problem with the supraspinatus tendon, which connects a shoulder muscle to the top of the upper arm bone in the front leg. The tendon can become damaged, inflamed, or begin to break down over time, often in response to repeated strain or wear. This is one of the more common soft-tissue problems affecting the shoulder in dogs, and can occur in cats as well, though less frequently. Owners often notice a front-leg lameness that may come and go, or a reluctance to bear full weight after exercise or rest. The limb may appear stiff when the dog first gets up, or the dog may hold the leg in a slightly altered position. Some dogs show discomfort when the shoulder is moved in particular ways, or when pressure is applied over the front of the shoulder. This page explores the signs that may point towards supraspinatus tendinopathy, what is happening within the tendon and surrounding structures, how the condition is investigated through examination and imaging, and the range of approaches that exist to support healing and manage discomfort. The course can vary widely depending on the severity of tendon damage and the individual animal's activity level and build.
