Features of an ulnar nerve lesion below the elbow

Authoring team

The clinical features of an ulnar nerve lesion below the elbow are presented according to the site of the lesion:

  • in the cubital tunnel the features resemble those of a lesion at the elbow except:
    • clawing is more prominent due to preservation of flexor digitorum profundus
    • flexor carpi ulnaris is spared and so wrist flexion is unaffected

  • at the wrist the features resemble those of a lesion at the elbow except:
    • there is no sensory loss because the dorsal cutaneous branch of the ulnar nerve is spared

  • in the hand the features resemble those of a lesion at the elbow except:
    • the hypothenar eminence is usually spared
    • wasting and weakness is confined to the interossei and adductor pollicis
