Sasuke grew extra arms while in his curse mark second state. He then absorbed Orochimaru's chakra and then he lost one of his extra arms in an explosion caused by Deidara. He used Orochimaru's ability to generate serpent limbs to replace his arm, but only while in second state. The arm retracts just like the other when he powers down.
