The integration of ultrasound into clinical practice revolutionized the diagnosis and management of nerve-related pathologies in the elbow and wrist. Clinicians gained the ability to perform rapid, non-invasive assessments at the point of care, facilitating early detection and targeted interventions. Ultrasound-guided procedures, including nerve blocks and hydrodissection, offered precise therapeutic options with reduced risk and improved outcomes. Moreover, ultrasound emerged as a valuable adjunctive tool in surgical planning and intraoperative guidance, optimizing surgical outcomes and minimizing complications.
