Flexor Carpi Ulnaris

ATTACHMENTS

It has got proximal and distal attachments as follows:

●       Proximally it is attached to

  • Medial Epicondyle of Humerus by tendon (Humeral Head).

  • Ulna over olecranon and upper dorsal border by Aponeurosis (flat tendon). (Ulnar Head)

●       Distally it is attached to

BLOOD SUPPLY

Flexor Carpi Ulnaris gets its blood supply from

  •   Ulnar Collateral arteries
  •   Anterior Ulnar Recurrent artery
  •   Posterior Ulnar Recurrent artery
  •   Ulnar artery (small muscular branches)
  •   Superficial Palmar Arch (Ulnar Side)

INNERVATION

Flexor Carpi Ulnaris is innervated by Ulnar Nerve (C7, C8)

ACTION

Flexor Carpi Ulnaris contract to flex and adduct the hand at wrist joint.

CLINICAL IMPORTANCE

If Ulnar nerve gets entrapped between its proximal two attachments it leads to Cubital Tunnel Syndrome.
