A stress fracture in musculoskeletal (MSK) ultrasound refers to a tiny crack in a bone, commonly caused by repetitive stress rather than a single traumatic event. In medical imaging, particularly with ultrasound, stress fractures can be challenging to detect in early stages, as they may not be visible on initial X-rays. Ultrasound can play a role in identifying soft tissue edema or periosteal reaction around the bone, which are indirect signs of a stress injury, guiding further diagnostic imaging.
For medical professionals and sonographers, understanding the nuances of stress fractures in MSK ultrasound is crucial for accurate diagnosis. High-frequency linear probes are typically used to assess subtle changes, helping differentiate between various musculoskeletal conditions. Early detection aids in preventing complete bone fractures and guides appropriate patient management and rehabilitation.
