A 32-year-old right-handed surgeon presented with a history of intermittent pain at the right medial epicondyle, a mild Tinel's sign, and dysesthesia in the ulnar nerve distribution. Dynamic ultrasound demonstrated a hypertrophic anconeus epitrochlearis bilaterally, and chronic irritation of the ulnar nerve. Anterior release with myectomy of the accessory muscle was performed. No compressive symptoms were present at 1-year follow-up.
The anconeus epitrochlearis is an often-underappreciated cause of ulnar nerve compression that can lead to significant functional impairment. Dynamic ultrasound is an excellent diagnostic modality, and anterior release with myectomy provides durable relief with minimal downtime.
