Ultrasound-Guided Perineural Injection for Pronator Syndrome Caused by Median Nerve Entrapment.
Patients and physicians have increasingly sought minimally invasive procedures such as ultrasound-guided injection for the treatment of peripheral nerve entrapment syndromes. In this series, we assessed subjective outcome data in 14 patients who underwent ultrasound-guided perineural hydrodissection and steroid injection for pronator syndrome secondary to median nerve entrapment in the pronator tunnel. Excellent symptomatic relief (≥75% improvement) was achieved in 70% of nerves with 3-month follow-up data, with no significant change in symptoms between 3 and 6 months. These outcomes suggest that this technique could play a role in the management of pronator syndrome due to median nerve entrapment.
