Infections of the Foot



- Diabetic Foot Infection

- Deep Puncture Wound:
    - puncture wounds most often result in staph aureus infections (most common organism), or pseudomonas infection (most common gram negative organism);
           - staph aureus is the most common organism in soft tissue infections, where as pseudomonas is the most common cause of calcaneal osteomyelitis arising from puncture wounds;
           - why pseudomonas infection is so common is unclear since intial cultures of the foriegn body will not grow pseudomonas;
    - puncture wounds of the forefoot often involve the MTP joints;
    - in most cases, these patients cannot be managed w/ medical therapy alone but will require formal incision and debridement;
           - essentially, it is up to the physician to prove that there is not retained foreign body (such as a piece of tennis shoe rubber) deep in the heel;
    - calcaneal osteomyelitis:
           - in the report by Rasool MN, et al (2001), 14 children (average 9 years) with primary hematogenous osteomyelitis of the calcaneus are reported;
                  - 4 were seen early and 10 late;
                  - clinical presentation was dramatic, with fever, pain, swelling, and fluctuance around the foot and ankle;
                  - the diagnosis was missed initially in 8 cases because the patients were treated for septic arthritis of the ankle, cellulitis, and subcutaneous abscess;
                  - 4 patients seen early healed well, with no complications;
                  - the 10 patients seen late had chronic osteomyelitis with growth arrest; shortening of the foot, limb length deficiency; fusion of subtalar, calcaneocuboid, and ankle joints; calcaneus and equinus deformity; avascular necrosis of the talus; and phalangeal loss;
                  - total calcanectomy (3 patients) and talectomy (2 patients) with heel pad preservation were useful salvage procedures avoiding ablation of the limb in chronic cases;
           - references:
                  - Partial and total calcanectomy: a review of thirty-one consecutive cases over a ten-year period.
                  - Partial calcanectomy for the treatment of large ulcerations of the heel and calcaneal osteomyelitis. An amputation of the back of the foot.
                  - Osteomyelitis of the calcaneum.
