Ee was using a hand crank to tighten a screen. His left thumb became entangled in the crank handle & was twisted. He did not seek medical attention until 12/5/05. The dr diagnosed sprain & returned him to full duty. On 3/22/06 he saw an Orthopedic specialist who determined he would have to have minor surgery on 3/29/06. No lost days, no restricted days.
