The Flexor carpi ulnaris is a superficial anterior muscle of the forearm.
Anatomical Attachments:
- Origin: There are two heads of the Flexor carpi ulnaris, the humeral head attaches to the medial epicondyle of the humerus and the ulnar head attaches from the olecranon process and the proximal posterior ulna.
- Insertion: Attaches to the pisiform bone, the hamate and the 5th metacarpal.
Action: Flexes and adducts the wrist and the hand, and aids with flexion of the forearm.
Synergist: Flexor carpi radialis, Palmaris longus.
Antagonist: Abductor pollicis longus, Flexor digitorum superficialis and profundus, Flexor pollicis longus.

Nerve Supply: Ulnar Nerve (C8, T1).
Nerve Entrapment: Entraps the ulnar nerve.
Vascular supply: Posterior ulnar recurrent artery.
Travell and Simons Trigger Point Pain Referral:
- Primary: The referred pain is primarily located on the anterior ulnar aspect of the wrist, with distribution being slightly proximal and distal of that sight, thus involving the forearm and palm.
- Satellite or associated triggers: According to Travell and Simons, the hand and finger flexors have a tendency to develop triggers collectively and have a spill over from activated triggers in the Pectoralis minor and Scalenes.

Trigger Point Signs and Symptoms: Pain during activities requiring gripping and wrist flexion.
Trigger Point Activating and Perpetuating Factors: Persistent or sustained gripping with wrist flexion, which is
frequently observed in persons who cup their hands over the end of a chair; skiers as a result of gripping poles or handles;
construction workers who use hand tools, which are either heavy or have persistent vibration such as jackhammers, saws or
drills
