The initial treatment of FCU Tendinosis is non-operative, and includes a steroid injection and physical therapy to strengthen the forearm muscles. These strengthening exercises are easy and can be learned in 1-2 therapy visits, and then performed every day at home. They should take no longer than 5 minutes each day.
What are the 2 movements of the flexor carpi ulnaris?
The flexor carpi ulnaris has two main actions: Flexion of the wrist – the movement of bending the wrist straight down. Adduction of the wrist – the movement of bending the wrist towards the pinky side of the arm.
What does the flexor carpi do?
Flexor carpi ulnaris muscle (FCU) is the most medial flexor muscles in the superficial compartment of the forearm. It can adduct and flex the wrist at the same time; acts in tandem with FCR to flex the wrist and with the extensor carpi ulnaris to adduct the wrist.
How does flexor carpi ulnaris work?
Flexor carpi ulnaris is a fusiform muscle located in the anterior compartment of the forearm. Together with other muscles of the anterior forearm, flexor carpi ulnaris flexes the hand at the wrist. Besides flexing the hand, flexor carpi ulnaris is also involved in adduction of the hand at the wrist.
Where does flexor carpi ulnaris insertion?

| Insertion | Pisiform, hook of the hamate, base of the fifth metacarpal bone (Volar Aspect) |

What movements does the flexor carpi ulnaris perform?
Flexor carpi ulnaris is the most medial of the superficial flexors. Together with other muscles of the anterior forearm, flexor carpi ulnaris flexes the hand at the wrist. Besides flexing the hand, flexor carpi ulnaris is also involved in adduction of the hand at the wrist.
How do you identify flexor carpi ulnaris?
The tendon of flexor carpi ulnaris can be seen on the anterior surface of the distal forearm. On a person’s distal forearm, just before the wrist, there are either two or three tendons. The tendon of the flexor carpi ulnaris is the most medial (closest to the little finger) of these.
How do I check my flexor carpi ulnaris?
The tendon of flexor carpi ulnaris can be seen and palpated beneath the skin immediately proximal to the wrist joint. It is the most medial of the tendons that are visible superficially in this region. Flexor carpi ulnaris lies superficial to flexor digitorum superficialis and medial to palmaris longus.
