Crepitus

Definition

Crepitus is a grating, crackling, or popping sound and sensation experienced under the skin and joints, often due to the presence of air in subcutaneous tissue or cartilage wear. It is commonly associated with conditions affecting the pulmonary and musculoskeletal systems.

5 Must Know Facts For Your Next Test

1. Crepitus can indicate underlying respiratory issues such as pneumothorax or subcutaneous emphysema.
2. In the musculoskeletal system, crepitus often signifies joint degeneration or cartilage wear, such as in osteoarthritis.
3. Nutritional deficiencies, especially in vitamins and minerals like calcium and vitamin D, can exacerbate conditions that lead to crepitus.
4. Proper hydration and balanced nutrition can help maintain cartilage health and potentially reduce occurrences of crepitus.
5. Assessing for crepitus involves both auditory (listening for sounds) and tactile (feeling for sensations) examinations during clinical assessments.
