Carpal tunnel syndrome (CTS) is a collection of characteristic
symptoms and signs that occurs following entrapment of the median nerve
within the carpal tunnel. Usual symptoms include numbness, paresthesias,
and pain in the median nerve distribution. These symptoms may or may
not be accompanied by objective changes in sensation and strength of
median-innervated structures in the hand. See image below.
