Complications from diabetic foot infections are a leading cause of nontraumatic lower-extremity amputations. Nearly 85% of these amputations result from an infected foot ulcer. Osteomyelitis is present in approximately 20% of diabetic foot infections. It is imperative that clinicians make quick and successful diagnoses of diabetic foot osteomyelitis (DFO) because a delay in treatment may lead to worsening outcomes. Imaging studies, such as plain films, bone scans, musculoskeletal ultrasound, computerized tomography scans, magnetic resonance imaging, and positron emission tomography scans, aid in the diagnosis. However, there are several mimickers of DFO, which present problems to making a correct diagnosis.
糖尿病足感染引发的并发症是非创伤性下肢截肢的主要原因。这些截肢手术中近85%是由足部感染性溃疡导致的。约20%的糖尿病足感染存在骨髓炎。临床医生必须快速且成功地诊断糖尿病足骨髓炎（DFO），因为治疗延迟可能导致病情恶化。影像学检查，如X线平片、骨扫描、肌肉骨骼超声、计算机断层扫描、磁共振成像和正电子发射断层扫描，有助于诊断。然而，有几种疾病与DFO相似，这给正确诊断带来了困难。
