He was one of about a dozen teenagers who were spelunking in the cave.
The 14-year-old, who was not identified, was taken to Augusta Health for treatment.
Crews from Augusta County Fire and Rescue and the Staunton and Waynesboro fire departments worked for more than three hours to extricate the boy.
He was wedged between two rocks, about 400 to 500 feet into the cave, said Augusta County Fire Capt. Nathan Ramsey said.
Rescue workers were able to free the boy and strap him to a skid to be taken from the cave.
Ramsey said the teenagers appeared to be on a day trip from a summer camp. Members of the group would not comment.
A medevac helicopter was standing by to transport the boy, but was not needed.
