Permanent nerve damage after corticosteroid injection has been suggested when symptoms of median nerve injury (MNI) are irreversible. We assess the outcomes of MNI and their association with ultrasonography (US)-guided hydrodissection and the following corticosteroid injection for symptomatic carpal tunnel syndrome (CTS). ⋯ MNI during hydrodissection may be reversible. MNI is indicated by an increase in MN-CSA-inlet immediately after hydrodissection.

To investigate how the extent of an ultrasound instructor's clinical expertise influences the level of hands-on ultrasound competency achieved by clinicians after three-day ultrasound courses in abdominal and emergency ultrasound. The second goal was to determine how physicians in residency rate the sonographic and didactic skills of student instructors compared to medical staff instructors. ⋯ The didactic competence of student instructors does not differ statistically from the competency levels of experienced physicians. In terms of the acquired ultrasound skills of trainees, our data indicate that student instructors can be as efficient as staff instructors. Therefore, student instructors can be employed as resource-saving ultrasound educators without decreasing the skills level achieved by course participants, provided that they previously underwent a comprehensive didactic and sonographic training program.
