Abdominal Exam III: Palpation

2023
Source: Alexander Goldfarb, MD, Assistant Professor of Medicine, Beth Israel Deaconess Medical Center, MA Abdominal palpation, if performed correctly, allows for examination of the large and relatively superficial organs; for a skilled examiner, it allows for assessment of the smaller and deeper structures as well. The amount of information that can be obtained by palpation of the abdominal area also depends on the anatomical characteristics of the patient. For example, obesity might make...

Knee Exam

Source: Robert E. Sallis, MD. Kaiser Permanente, Fontana, California, USA The knee is a hinged joint that connects the femur with the tibia. It is the largest joint in the body, and due to its location in the middle of the lower leg, it is subjected to a variety of traumatic and degenerative forces. Examination of the knee can be quite complex, owing to the fact it is an inherently unstable joint held together by various ligaments and supported by menisci, which act as shock absorbers and...

The Comprehensive Infant Examination

Source: Heather Collette and Jaideep Talwalkar; Yale School of Medicine The newborn exam is important in establishing a baby's baseline health status as they enter the world. Newborn providers have the unique opportunity to evaluate a patient for the very first time. They are also tasked with identifying congenital anomalies that require early intervention to promote a long and healthy life for the child. Many newborn anomalies, such as heart defects, are noted on prenatal ultrasound. However,...
FAQs
In a damaged joint, irregular or roughened articular surfaces can contact one another as the joint moves, creating a grating or crackling sensation. This mechanical source differs from a brief pop caused by gas movement in synovial fluid. Recognizing the likely source helps clinicians interpret the sound together with pain, swelling, restricted motion, and the patient’s injury history.
Gas movement within synovial fluid may produce a short-lived popping sound during joint motion. Because this mechanism is distinct from persistent grating associated with irregular articular surfaces, the duration and character of the sound can provide useful context. Clinicians do not interpret the pop alone; they consider accompanying symptoms and other examination findings before deciding whether it appears benign or needs further assessment.
In soft tissue, trapped air beneath the skin can create a fine crackling feeling when the area is examined or moved. This finding has a different mechanism from sounds generated inside a joint, because the air is located in tissue rather than synovial fluid or between articular surfaces. Its presence therefore prompts attention to the clinical setting and associated findings.
The sound or sensation should be assessed alongside pain, swelling, restricted movement, injury history, and other clinical findings. A joint sound without concerning accompanying features may be interpreted differently from crepitus occurring with symptoms or after trauma. This combined assessment helps clinicians distinguish potentially benign joint popping from findings associated with osteoarthritis, inflammation, or injury.
Clinicians assess crepitus while considering the involved joint or soft tissue and the circumstances in which it occurs. They correlate the finding with movement, pain, swelling, restricted motion, injury history, and other examination results. This process does not rely on the sound alone; the combined pattern guides whether the finding is likely benign or warrants further assessment.
Crepitus can contribute to the clinical assessment of osteoarthritis, trauma, inflammation, and subcutaneous emphysema. Its significance depends on whether it arises from roughened articular surfaces, gas in synovial fluid, or air trapped beneath the skin, as well as on accompanying findings. The result is a contextual clinical sign that may help determine whether additional evaluation is needed.
