Anterior ulnar recurrent artery

Arteria recurrens ulnaris anterior

Origin
Arises from the proximal ulnar artery below the medial epicondyle
Insertion
Ascends anterior to the medial epicondyle to anastomose with the inferior ulnar collateral artery
Function
Supplies the medial anterior elbow joint capsule and flexor origins; contributes to cubital anastomosis
Innervation
Sympathetic perivascular plexus
Movement & chain
Subject to dynamic compression during extreme elbow flexion
Palpation
Not palpable through overlying pronator teres muscle
Clinical
Preserves distal forearm perfusion in cubital fossa vascular injuries
Segmental innervation
C7–T1 roots
In clinical practice
Critical collateral landmark in medial epicondylectomy and anterior transposition of the ulnar nerve
