i twisted my foot on 7-1-04 and suffered a jones fracture. I was put in a nwb cast for 4 weeks after 4 weeks the x-rays showed no appreciable healing .i’m now in a nwb cast for another 4 weeks. if no appreciable healing was done in the first 4 weeks, what would make the next 4 weeks any different? is there a possibility that substantial healing could take place in these next 4 weeks? what can I do? should I take calcium supplements? thanks for your input!
