Elbow Exam

Source: Robert E. Sallis, MD. Kaiser Permanente, Fontana, California, USA The elbow is a hinged joint that involves the articulation of 3 bones: the humerus, radius, and ulna. It is a much more stable joint than the shoulder, and because of that, the elbow has less range of motion. The elbow and its structures are prone to significant injuries, particularly with repetitive motion. Lateral and medial epicondylitis (also called tennis elbow and golfer's elbow) are two common diagnoses and often...

We describe a new ultrasound-based vector tissue Doppler imaging technique to measure muscle contraction velocity, strain and strain rate with sub-millisecond temporal resolution during dynamic activities. This approach provides complementary measurements of dynamic muscle function and could lead to a better understanding of mechanisms underlying musculoskeletal disorders.

Goergen, Weldon School of Biomedical Engineering, Purdue University, West Lafayette, Indiana High-frequency ultrasound systems are used to acquire high resolution images. Here, the use of a state-of-the-art system will be demonstrated to image the morphology and hemodynamics of small pulsatile arteries and veins found in mice and rats. Ultrasound is a relatively inexpensive, portable, and versatile method for the noninvasive...

Source: Joseph H. Donroe, Rachel Liu; Yale School of Medicine, USA Point of Care Ultrasound or POCUS is easy to use, has enhanced mobility due to the smaller equipment needed, and may be carried out in a variety of settings. It is also far safer and cheaper than imaging techniques like computer tomography. POCUS can be helpful when certain physical exam findings are difficult to appreciate by palpation, percussion, or auscultation and can facilitate learning elements of the cardiac, pulmonary,...
FAQs
Image formation depends on acoustic echoes returning from structures within the elbow. The transducer sends high-frequency sound pulses into the region, and differences in tissue composition affect the echoes that return. The ultrasound system processes these signals into images, allowing clinicians to examine joint structures and surrounding soft tissues during the assessment.
Real-time imaging allows clinicians to observe how elbow tissues behave during movement rather than evaluating only a static image. This dynamic examination can help assess structures as they move and may reveal abnormalities associated with injury or inflammation. It also supports a more functional assessment of the joint and its surrounding tissues.
The examination can assess several tissue categories around the elbow, including tendons, ligaments, muscles, nerves, fluid collections, and the joint itself. This broad coverage allows clinicians to look for tissue changes, fluid-related findings, and joint abnormalities. The range of visible structures makes the technique useful in musculoskeletal assessment rather than for a single tissue type.
Its portability and lack of radiation support use in a range of clinical settings. Because the technique can produce images during examination, clinicians can assess the elbow in real time without relying on a fixed imaging environment. These characteristics make it practical for musculoskeletal diagnosis, follow-up, and assessment alongside other clinical information.
A transducer is applied to the elbow region and sends sound pulses into the tissues. The returning echoes are converted into images while the clinician examines the joint and surrounding structures, potentially during movement. The opposite elbow may also be used for comparison, helping clinicians evaluate whether an observed finding differs from the patient’s other side.
Clinicians may use the examination to investigate elbow injury, inflammation, fluid collections, or other joint and soft-tissue abnormalities. Its ability to show tissue movement supports dynamic assessment, while repeat imaging can help monitor recovery over time. The technique can also support image-guided procedures, extending its role beyond diagnosis alone.
