From The Collaborative International Dictionary of English v.0.48 [gcide]:

  Thoroughpin \Thor"ough*pin`\, n. (Far.)
     A disease of the hock (sometimes of the knee) of a horse,
     caused by inflammation of the synovial membrane and a
     consequent excessive secretion of the synovial fluid; --
     probably so called because there is usually an oval swelling
     on each side of the leg, appearing somewhat as if a pin had


     been thrust through.
     [1913 Webster]
