Fractured fifth metatarsal

Hi,

I'm seventeen and I'm flat footed, and have had knee pains, and lower back problems, the knee problems related and the lower back i'm uncertain as to its connection or otherwise.

Anyway, two weeks ago, I fractured my fifth metatarsal and the doctor determined it was a 'jones fracture' i applied pressure on the outside corner of my left foot, all of my pressure, and did a calf-raise similar movement, i was bouncing slightly after scoring an important point in a game of basketball and heard a loud pop, my foot immediately dropped to flat, and began to swell inside my shoe. I have had pains in the outsides of my feet before, and assume it is the same bones, but on that day felt no pain until the pop.

I was wondering if any physio/doctor/anybody with experience in this area has any suggestions of the cause? ways to make it heal faster? prevent it from happening again? and most importantly, is there any exercises I should be doing, for my legs and the rest of my body, that I can undertake safely while still allowing the bone to heal correctly?

EDIT:
I am currently entering my third week, did it 2 sundays ago, and the doctor put me in a moon boot and ordered me to stay off of it(crutches) for the last 5 weeks.

General rules of fracture healing are that it is beginning to knit at 6 weeks. This will not be ready for weight-bearing for a lot longer and so that unfortunately means no basketball for several months.

Please do note that just about all the literature says that patients should not place weight on the foot until instructed by their doctor. After that you'll be using crutches for the initial healing phase.

Jones fractures occur in a small area of the fifth metatarsal that receives less blood and is therefore more prone to difficulties in healing. They can become chronic conditions if the fracture fails to unite, or heal. If this is the case, surgery will likely be recommended to secure the fracture in place with a screw, and bone graft may be used to stimulate a healing response. i.e. Listen to the Dr and don't rush the return to sport.
