I think he won a Major after that accident. There was a movie about it,

Hogan turned pro in 1929, at age 17, to play pro events in Texas. He didn't join the PGA Tour until 1932. Much of his early career, Hogan battled a hook. But through a tremendous work ethic, he changed his game to a controlled fade (in his famous words, he "dug it out of the dirt"). In 1940, he began winning, and often.
He missed a couple years on Tour due to World War II, but returned full-time in 1946 and won 13 times, including his first major, the 1946 PGA Championship. From August 1945 to February 1949, Hogan won 37 times. But in 1949, he suffered terrible injuries in a car crash, and was never again able to play a full schedule due to circulatory problems in his legs.
Sixteen months after that crash - in which Hogan threw himself across his wife to protect her as their car collided with a bus - Hogan returned to win the 1950 U.S. Open. That victory is sometimes referred to as "the miracle at Merion," because Hogan won despite severe pain and having to play 36 holes on the final day.
In fact, from 1950 on, Hogan never played more than seven PGA Tour events in a year. Yet, he won 13 more times, including six majors. Until Tiger Woods did it in 2000, Hogan was the only man to win three professional majors in one year. That was in 1953, when Hogan won the Masters, U.S. Open and British Open. (He didn't play the PGA Championship because that tournament's dates conflicted with the British Open's.) From 1946 to 1953, Hogan won nine of the 16 majors he played.
