Abductor Digiti Minimi (Hand) Trigger Points
Symptom Area: Forearm and Hand
Abductor Digiti Minimi (Hand) Trigger Points are explored here through their location and referred pain pattern. Muscle knots is an everyday term used for tender muscular spots; myofascial pain describes pain involving muscle and its surrounding connective tissue. Hypothenar muscle that abducts the little finger; trigger points give pain along the ulnar border of the hand and into the fifth finger.
Where you feel it
When the Abductor Digiti Minimi (Hand) holds active trigger points, you usually notice it as dorsal finger pain and volar finger pain. Where the pain spreads: Pain along the ulnar side of the hand extending into the little finger, sometimes mistaken for ulnar nerve irritation. What often sets it off: Sustained gripping, repetitive mouse or tool use, leaning on the ulnar border of the hand while writing or typing, playing string instruments.
Overview
Abductor digiti minimi forms the bulk of the hypothenar eminence, running from the pisiform to the base of the little finger. It abducts the fifth digit and assists cupping of the palm. Its referred pain overlaps with the first dorsal interosseus, so both are often illustrated on the same figure.
Trigger point locations
Points in the hypothenar belly just distal to the pisiform and along the ulnar border of the palm.
Referred pain pattern
Pain along the ulnar side of the hand extending into the little finger, sometimes mistaken for ulnar nerve irritation.
Palpation & testing
Support the hand palm-up and use a pincer grip on the hypothenar eminence; taut bands lie parallel to the fifth metacarpal and are tender to cross-fibre pressure.
Common causes
Sustained gripping, repetitive mouse or tool use, leaning on the ulnar border of the hand while writing or typing, playing string instruments.
Self-care & clinical treatment
Self-massage of the hypothenar pad, finger abduction and spreading exercises, wrist and hand ergonomics, forearm-supporting mouse setup. Clinically: manual release and gentle needling, screening for ulnar nerve involvement.
Treatment protocol
For Abductor Digiti Minimi (Hand), the general protocol applies: sustained pressure release on the taut band, then stretch and active movement in the newly gained range.
Position and palpation: Support the hand palm-up and use a pincer grip on the hypothenar eminence; taut bands lie parallel to the fifth metacarpal and are tender to cross-fibre pressure.
Regional precaution for clinicians: In the forearm and hand the median nerve at the pronator teres, the ulnar nerve at the cubital tunnel and Guyon's canal, the radial nerve in the supinator arcade and the radial artery at the wrist are all superficial and must be avoided; needles are short and angled away from the neurovascular bundles.
