Hello! I'm looking for any research articles that pertain to foot
disorders leading to lower back pain/ disorders. To make a long story
short, I have a patient who had a stress fracture in his left foot. He
was placed into a cast for a period of 6 months, he was only able to
"hobble around". After the cast was removed, he continued to limp and
he now uses a cane. He is now complaining of lower back pain with
sciatica. MRI results showed L4-5 and L5-S1 disc herniations. I'm
trying to prove in a court that the altered biomechanics of his
walking and activities of daily living placed enough stress in his
back to cause injury. Any help would be greatly appreciated. Thanks!

Would this help?

Hi

Although I am not mediacally trained in any way, I would send him to
an osteopath or chiropractor.  Pain in one area of the body can easily
be caused by a problem in a completely different, and seemingly
totally unrelated area of the body.  An osteopath or chiropractor
would be able to check all that out and realign and balance whatever
is off balance.  Hobbling around for a long time could certainly place
stress on the back.  Personally, if I allow the heel of my right shoe
to wear down too much, I get lower back pain which disappears when I
get new shoes.

Hope that helps

Jane
