He's a she and she generally does because unlike surgeons she's a sports PT by trade and she works with those rehabbing their orthopedic injuries conservatively as well as agressively.
Foot injuries like this are tougher than normal to heel because there isn't tremendous blood flow to some of the areas in the foot. Generally speaking a bone in another location starts to knit in 10 days and heels in 6-8 weeks or less with non or minimal weight bearing. These injuries on the other hand sometimes don't respond to upwards of 20 weeks of non or minimal weight bearing, and sometimes they don't even heel following surgery. That is why someone suggested he will likely be using a stimulator device that electronically increases blood flow to the area to promote healing.
If the screw holds and the bone knits he'll be fine (until arthritis sets in in his mid to late 40's...). If it doesn't then this could become a real career threatener. Hopefully they nail him to a chair for the next month or so and put a really annoying alarm on his walking boot so he doesn't abuse or remove it...
