Surgery is necessary in many cases of diabetic foot osteomyelitis. The decision to undertake surgery should be based on the clinical presentation of diabetic foot osteomyelitis. Surgery is required when the bone is protruding through the ulcer, there is extensive bone destruction seen on x-ray or progressive bone damage on sequential x-ray while undergoing antibiotic treatment, the soft tissue envelope is destroyed, and there is gangrene or spreading soft tissue infection. Several issues should be taken into account when considering surgery for treating diabetic foot osteomyelitis. It is necessary to have a surgeon available with diabetic foot expertise. Regarding location of diabetic foot osteomyelitis, it is important to consider whether isolated bone or a joint is involved. In cases in which osteomyelitis is associated with a bone deformity, surgery should be able to correct this. The surgeon should always reflect about whether extensive/radical surgery could destabilize the foot. The forefoot is the most frequent location of diabetic foot osteomyelitis and is associated with better prognosis than midfoot and hindfoot osteomyelitis. Many surgical procedures can be performed in patients with diabetes and forefoot ulcers complicated by osteomyelitis while avoiding amputations. Performing conservative surgeries without amputations of any part of the foot is not always feasible in cases in which the infection has destroyed the soft tissue envelope. Attempting conservative surgery in such cases risks infected tissues remaining in the wound bed leading to failure. The election of different surgical options depends on the expertise of the surgeons selected for the multidisciplinary teams. It is the aim of this article to provide a sample of surgical techniques in order to remove the bone infection from the forefoot while avoiding amputations.
