A fusiform muscle situated in the anterior forearm. It is one of the superficial forearm flexors, along with the pronator teres, palmaris longus, flexor digitorum superficialis and flexor carpi radialis muscles.
The muscle on the ulnar side that bends the wrist.
Flexor carpi ulnaris is the most medial of this group and as well as flexing the wrist with the flexor carpi radialis and adducting the wrist with the extensor carpi ulnaris, which can be done at the same time. The flexor carpi ulnaris is the only anterior compartment muscle that receives full innervation from the ulnar nerve.
Medial epicondyle of humerus, olecranon and posterior border of ulna.
Pisiform bone, hamate bone, base of 5th metacarpal bone.
Wrist joint: Wrist flexion, wrist adduction.
Ulnar nerve (C7-T1).
Posterior ulnar recurrent artery, ulnar artery.
Cubital tunnel syndrome occurs when the ulnar nerve is trapped and compressed in between both heads of the Flexor Carpi Ulnaris Aponeurosis, this occurs at the cubital tunnel and is a common upper limb compression neuropathy.
Flexor carpi ulnaris tendinopathy, an overuse injury, presents with ulnar sided wrist pain and is brought on during wrist flexion and ulnar deviation.
