Anterior interosseous
Patient, man 44 years old weightlifter, with clinical signs of anterior interossious syndrome for 3 months. Electroneurography and electromyography confirmed the diagnosis of AIN syndrome with pronounced periferal nerve damage. Echoneurography shows a significant enlargement of AIN, compared to the healthy arm, when it branches of the median nerve during it’s passage through the pronator teres muscle. Such findigns support the decision to perform surgical decompression if that treatment option is being considered.
Anterior interosseous enlargement at pronator exit. Image acquisition in reverse, proximal direction. Approx. 8-9 months since symptom onset.
Anterior interosseous with median nerve at pronator exit. Normal. Same patient, opposite arm.
