The present study has 3 aims: (a) to characterize the clinical and pathological features of diabetic foot infections, (b) to show the range of clinical presentations of moderate infections, and (c) to analyze the different behavior of diabetic foot osteomyelitis regarding to its clinical presentation. A definitive diagnosis of the type of infection was made based on intraoperative findings and histopathology. Diabetic foot infections were classified into 2 types: soft tissue and bone infections. Mild infections were always superficial. Severe infections included 75% of necrotizing soft tissue infections. Moderate infections showed ample range of clinical presentations. Eighty-one patients presented osteomyelitis. Osteomyelitis was further classified as follows: osteomyelitis without ischemia and without soft tissue involvement (class 1), osteomyelitis with ischemia without soft tissue involvement (class 2), osteomyelitis with soft tissue involvement (class 3), and osteomyelitis with ischemia and soft tissue involvement (class 4). Forty-eight patients (59.3%) with osteomyelitis underwent conservative surgery, 32 (39.5%) had minor amputations including 9 open transmetatarsal amputations, and there was 1 (1.2%) major amputation. The characterization of osteomyelitis into 4 classes showed a statistically significant trend toward increased severity and increased amputation rate and mortality. In conclusion, the clinical presentation of foot infections in diabetic patients is very heterogeneous and can be classified into soft tissue infections (cellulitis, superficial and deep abscesses, and necrotizing soft tissue infections) and osteomyelitis, which was the most frequent type of infection found in the author's series. Their division into 4 classes showed a statistically significant trend toward increased severity, amputation rate, and mortality. The diagnosis of deep soft tissue infections associated with osteomyelitis may be difficult to achieve before surgery.

The most dreaded major donor-site complication of free fibula flap is a foot ischemia, which is fortunately rare. Various authors have discussed the efficacy of the use of preoperative imaging methods including color Doppler, magnetic resonance angiography, and conventional angiography. A 25-year-old man presented with a 10-cm mandibular defect after a facial gunshot injury. Lower extremity color Doppler revealed triphasic peroneal, tibialis anterior, and posterior artery flows. A fibula osteocutaneous flap was harvested, and the mandible was reconstructed. However, the suture sites at the donor site began to demonstrate signs of necrosis, abscess formation, and widespread cellulitis beginning from postoperative day 9. Angiogram of the lower extremity on the 13th day demonstrated no flow in the right posterior tibial artery distal to the popliteal artery, whereas the anterior tibial artery had weak flow with collateral filling distally. An emergency bypass with a saphenous vein graft between the popliteal artery and the distal posterior tibial artery was performed. Repeated debridements, local wound care, and vacuum-assisted closure were applied. A skin graft was placed eventually. The extremity healed without severe functional disability. In conclusion, although the arterial anatomy is completely normal in preoperative evaluation, vascular complications may still ocur at the donor fibula free flap site. In addition, emergency cardiovascular bypass surgery, as we experienced, may be necessary for limb perfusion.

Infected popliteal aneurysm is a high-risk condition that may present as an emergency requiring an urgent attention with acute rupture and sepsis. The management of acute ischemia in the presence of local and systemic sepsis is challenging, and infection control and perioperative management during surgery are important. Here we report successful case of treating a patient with an infected popliteal aneurysm. The infection seemed to arise from the soft tissue surrounding the aneurysm, following cellulitis. Our report also includes a review of the related literature and suggests that devising methods for infection control is critical in achieving acceptable outcomes in such cases.
