An ulnar claw, also known as claw hand or Spinster’s Claw, is a deformity or an abnormal attitude of the hand that develops due to ulnar nerve damage, causing paralysis of the lumbricals. A claw hand presents with a hyperextension at the metacarpophalangeal joints and flexion at the proximal and distal interphalangeal joints of the 4th and 5th fingers.
