Guyon's canal syndrome, sometimes referred to as Handlebar palsy, is caused by entrapment of the ulnar 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 ulnar nerve. Guyon's canal syndrome is commonly seen in regular cyclists due to prolonged pressure of the Guyon canal against bicycle handlebars.
Famous quotes containing the words syndrome and/or canal:
“Women are taught that their main goal in life is to serve othersfirst men, and later, children. This prescription leads to enormous problems, for it is supposed to be carried out as if women did not have needs of their own, as if one could serve others without simultaneously attending to ones own interests and desires. Carried to its perfection, it produces the martyr syndrome or the smothering wife and mother.”
—Jean Baker Miller (20th century)
“My impression about the Panama Canal is that the great revolution it is going to introduce in the trade of the world is in the trade between the east and the west coast of the United States.”
—William Howard Taft (18571930)
