If you have a longstanding open wound, or an ulcer, then there is a chance that the bone underlying the sore may be infected in your foot. It is important to know if there is an underlying bone infection, or osteomyelitis, so that your doctor can accurately treat the bone infection. But how can the doctor determine if the bone is infected, or is it just a soft tissue infection around the sore? Your doctor will take an Xray of the foot which shows the bone underlying the sore. There are certain changes to the bone that can be seen on the Xray that will indicate a bone infection. If there are no changes on Xray but your doctor still suspects a bone infection, you may need to get an MRI of the foot. An MRI can show bone marrow changes that may indicate an infection. If this is still inconclusive, then the doctor may have to take a bone biopsy, or a tiny piece of the bone and send it to the lab to see if it grows any bacteria.
The most important thing to note is that if you have a sore on your foot, don't delay in getting it treated. Call our doctors at Prairie Path Foot and Ankle Clinic today and have your foot examined, and have treatment started.
