FYI: After visiting the OUCH center in Temecula, CA I have some more info.
The fracture above is known as a "Jones Fracture". It typically does not heal well in adults because the tendons in the foot are constantly pulling the 2 pieces of the bone apart. Treatment is 1 of 2 choices: Put the foot in a boot for 6-8 weeks and then re x-ray to see if it healed OR surgery to screw the bone back together and then 4 weeks of recovery.
After consulting with OUCH and a orthopedic surgeon I choose the surgery route. It's the best option for a full recovery and will get my foot back to 100% in the shortest amount of time.
WARNING! To all middle aged bike racers:
Indoor play areas with slides and inflatable jump houses are designed for kids, NOT adults. Even though it is you son's 8th birthday and you want to join in the fun with him, don't do it.
