What is a "Stress Fracture"?


------------------------------------------------------------------------------

QUESTION:  Our son the weekend athlete informed us that he has suffered a
"stress fracture" in his foot, but that everything is alright and he is up and
about.  My daughter in law says the x-rays were negative and that even a cast
wasn't needed.  Of course none of this makes sense to us.  Can you please
explain?

------------------------------------------------------------------------------

ANSWER:  Your son isn't using a made up condition to extract sympathy, and all
the details you provided do make sense.  There is no cause for alarm, but
stress fractures are a common enough occurrence to warrant a word or two.
Although they may affect any bone of the foot, the metatarsals (the bones that
form the broad part of the foot between the heel and the toes) are the most
common site for these injuries.  Such fractures are also named "march
fractures" as they can frequently be diagnosed in soldiers after prolonged,
forced marches.  Stress fractures develop when activity is suddenly increased,
and overcomes the ability of the bone to respond to these increased forces.
The first sign is pain and tenderness over the site of the fracture, and it is
common for the initial x-rays to be "negative", or fail to show the fracture
line, for it is a thin hairline type of break.  In general, repeat x-rays
after 2 to 6 weeks will eventually show the fracture.  In some cases, however,
other tests such as bone scanning or computer tomography (CT scan) are
necessary to detect the fracture.  Casting is only required in a few cases, as
a stress fracture will heal if the patient will back off from excessive
activity and stress and provide a relative rest to the foot.  I am sure your
son will do just that, and then return to his weekend activities with just a
bit more caution.
