Idiopathic Ulnar neuropathy at the elbow (aka Ulnar nerve entrapment or Cubital tunnel syndrome) is a condition where pressure on the ulnar nerve as it passes through the cubital tunnel causes nerve dysfunction (neuropathy). The symptoms of neuropathy are paresthesia (tingling) and numbness (loss of sensibility) primarily affecting the little finger and ring finger of the hand. Ulnar neuropathy can progress to weakness and atrophy of the muscles in the hand (interossei and small and ring finger lumbricals). Symptoms can be alleviated by attempts to keep the elbow from flexing while sleeping, such as sticking one's arm in the pillow case, so the pillow restricts flexion.
