Imaging of the shoulder

Diagnosis of lameness associated with the shoulder region requires a careful clinical examination, the use of specifically placed intra-articular analgesia and a combination of some common imaging techniques to accurately define the source of pain. Most equine practices performing lameness examinations in the horse have the radiographic and ultrasonographic equipment necessary to accurately image the shoulder. This article presents a description of the unique anatomy of the shoulder and the specific application of radiographic and ultrasonographic techniques to provide a complete set of diagnostic images of the shoulder region. A brief discussion of nuclear scintigraphy of this region is also included.
