The hypothenar muscles are a group of three muscles of the palm that control the motion of the little finger.

Carpal tunnel and thenar and hypothenar eminences

The three muscles are:^[1]

Abductor digiti minimi
Flexor digiti minimi brevis
Opponens digiti minimi

Structure

The muscles of hypothenar eminence are from lateral to medial:

Opponens digiti minimi
Flexor digiti minimi brevis
Abductor digiti minimi

The intrinsic muscles of hand can be remembered using the mnemonic, "A OF A OF A" for, Abductor pollicis brevis, Opponens pollicis, Flexor pollicis brevis, Adductor pollicis (thenar muscles), Opponens digiti minimi, Flexor digiti minimi, Abductor digiti minimi (Hypothenar muscles).^[2]

Clinical significance

"Hypothenar atrophy" is associated with the lesion of the ulnar nerve, which supplies the three hypothenar muscles.

Hypothenar hammer syndrome is a vascular occlusion of this region.^[3]

BACKGROUND: Hook of the hamate fractures are particularly rare carpal fractures with significant morbidity if not diagnosed early. Classically, these fractures occur from localized blunt trauma to the hook of the hamate in racket sports. Common complaints include pain localized in the hypothenar emi
