From an orthopaedic website about the fifth metatarsal....
What happens after surgery?
"For the first seven to 14 days after surgery, you may be allowed to weight bear through the heel, but some surgeons will not allow you to bear any weight on the injured foot. This could last as long as six weeks. Weight bearing in a removable walking boot is allowed after that. Patients can expect to return to full activity three to four months after a typical fracture. This includes returning to sports. Some fractures may require bone grafting and have longer recoveries. The screw is not usually removed unless it causes discomfort."
I always thought 6 to 8 weeks.
