The bone cortex, or cortical bone, is the dense, outer layer of bone tissue crucial for skeletal integrity within musculoskeletal (MSK) ultrasound. Its echogenic appearance makes it a key landmark for identifying fractures, assessing bone surface irregularities, and evaluating surrounding soft tissues. Understanding its sonographic characteristics is vital for accurate MSK diagnostics.
In medical ultrasound, the bone cortex serves as a primary reference point for imaging tendons, ligaments, and muscle attachments. Clinicians rely on its distinct hyperechoic signature to differentiate between healthy and pathological conditions, guiding interventions and monitoring healing processes effectively.
