Stressed Out

You can’t watch ESPN without hearing about it. You probably know someone that has gotten one. We're talking about stress fractures. They occur often in athletes and those in the military. So how is it different from a regular break? A normal (acute) fracture is the result of a traumatic experience, such as a collision or a fall. A stress fracture occurs when repetitive forces act on the bone and overload it. Let’s use the leg as an example. For runners, their leg and foot muscles are constantly working to move and absorb shock. These muscles work by shortening (contracting)from their bony attachments creating a pulling force. After a long time these muscles tire out and your bones become the shock absorbers. Those who have excessive pronation (functional flat foot)are also susceptible to these types of fractures.

How do you tell if you have one? Stress fractures usually occur very gradually. You likely won’t remember the exact day it happened but that the pain has gotten worse. While it’s hard to name only one prevention for stress fractures, there are a few ways to play defense. Make sure you are getting enough calcium and vitamin D for bone development. If you are a runner, especially one trying to get back into it after a long hiatus, try to follow the runner’s rule. It states that you shouldn’t increase distance by more than 10% per week to allow your bones and muscles to adapt. Also make sure you are wearing proper footwear. Runners should change their shoes about every 400-600 miles depending on brand and grade of shoe. I know you may say your shoes are clean and you’ve taken care of them. But the midsole is the part doing the work and if it can’t absorb shock anymore, then your bones take the hit. If you think you may have a stress fracture come by and see your podiatrist. Treatment ranges from rest from activity, to a cast or boot to keep the bone immobilized. Orthotics may also be used to correct the pronation that can cause these. Come by and see Dr. Grimm or Dr. Pattison to get a break from life’s stresses.
