According to this article on Hollywood.com, Harrison Ford will take six months off from filming to return to the U.S. for treatment on his shattered leg. It goes on to say:
“It has now emerged that he will not be able to return to film Star Wars: Episode VII for six months as he needs rehab treatment for his left limb, which was fixed with a number of metal plates during surgery this week. A source tells Britain’s The Sun newspaper, “Shooting is continuing, but Harrison won’t be back for months… the film company is looking into extending filming well into the second half of this year to allow Ford time to get back on his feet.” Ford is still receiving treatment at a hospital in England but will fly back to Los Angeles with his actress wife Calista Flockhart to work with a physiotherapist, according to editors at the publication.”
