The Week contest: Rock injury

This week's question: Rock-guitar virtuoso Steve Vai needed finger surgery because he held the same complex chord for 20 minutes during a practice session. "I had to put my thumb in this really weird position," explained Vai, 60. Please come up with a medical term to describe an injury suffered while pushing rock guitar to its physical limits.
