I was on my way to work one icy morning a few years ago and took a nasty fall, spiral fracturing my tibia and fibula. I was shocked that my bones could break so easily -- I took calcium every day and was certain that I was strong and healthy. How was it possible then that my leg was shaped like a giant S? Why did I have to suffer through two surgeries and have my leg rebuilt with screws and pins like a demented jigsaw puzzle? Six plus weeks of not bearing any weight on my leg seemed like an evil prison sentence!
