ABSTRACT
Posterior interosseous nerve (PIN) lesion is rare. We report the case of a 33-year-old female patient who developed an isolated progressive extension deficit of the 3rd, 4th and 5th right fingers with pain on the anterior aspect of the elbow progressing for 5 months. Clinical examination did not find any paresthesia. Electromyography (EMG) showed partial axonotmesis of PIN. Surgical exploration found PIN compression by the supinator arch. The patient underwent neurolysis with full recovery within 2 months.
