Principle Management
1. Diagnosis of soft tissue infection VS osteomyelitis
2. Control blood sugar and co-morbid condition (esp. Cardiac disease)
3. Assessing severity and Eradicated infection• Antibiotic
• Limited debridement and amputation
4. Microbiologic consideration • tissue specimen culture
5. Evaluation vascular supply and revascularization as indicated
6. Off-loading technique• Total Contact Cast (TCC) or other instrument
