Ultrasound-Guided Perineural Injection for Pronator Syndrome Caused by Median Nerve Entrapment

Area of Science:

• Neurology
• Musculoskeletal Medicine
• Medical Imaging

Background:

• Peripheral nerve entrapment syndromes, like pronator syndrome, often necessitate treatment.
• Minimally invasive procedures are increasingly preferred for managing these conditions.
• Ultrasound-guided injections represent a key advancement in interventional pain management.

Observation:

• This study evaluated 14 patients with pronator syndrome due to median nerve entrapment.
• The procedure involved ultrasound-guided perineural hydrodissection and steroid injection.
• Subjective outcome data were collected to assess treatment effectiveness.

Findings:

• Excellent symptomatic relief (≥75% improvement) was observed in 70% of treated nerves.
• Symptom improvement remained stable between 3 and 6 months post-procedure.
• No significant adverse events were reported, indicating a favorable safety profile.

Implications:

• Ultrasound-guided hydrodissection and steroid injection show promise as a valuable treatment for pronator syndrome.
• This minimally invasive approach may offer an alternative to surgical interventions.
• Further research could explore long-term outcomes and broader applications in nerve entrapment management.
