<unk> , also known as Guyon's canal syndrome or Handlebar palsy, is caused by entrapment of the<unk>  nerve in the Guyon canal as it passes through the wrist. Symptoms usually begin with a feeling of pins and needles in the ring and little fingers before progressing to a loss of sensation and/or impaired motor function of the intrinsic muscles of the hand which are innervated by the<unk>  nerve.<unk>  is commonly seen in regular cyclists due to prolonged pressure of the Guyon's canal against bicycle handlebars. Another very common cause of sensory loss in the ring and pink finger is due to<unk>  nerve entrapment at the cubital tunnel near the elbow, which is known as cubital tunnel syndrome.
