How did Jurgis injure his foot? What was the consequence of his injury?

Jurgis scrambles away from the steer and his foot becomes caught in the trap that collects the blood. He twists his ankle. The next day, his ankle is swollen and he wraps it in rags and goes to work anyway. It begins to hurt so badly that he passes out. A company doctor sees him and tells Jurgis that he must go home and go to bed. It could be months before the ankle properly heals. Jurgis is unable to work.
