Management of Chronic Non-Healing Wound Post-Fibular Fracture

Diagnosis of Osteomyelitis

The American College of Infectious Diseases recommends obtaining plain radiographs of the affected leg to look for bone changes, including periosteal reaction, lucency, or sequestrum formation, to diagnose chronic osteomyelitis 1, 2
The Infectious Diseases Society of America suggests performing the probe-to-bone (PTB) test during wound examination, as osteomyelitis is highly likely if the probe reaches bone 3
If radiographs are negative but clinical suspicion remains high, the American College of Radiology recommends obtaining MRI, which is the gold standard for diagnosing osteomyelitis in the setting of chronic wounds 2, 3
The Infectious Diseases Society of America recommends considering bone biopsy for culture if osteomyelitis is confirmed, as this provides the most accurate microbiologic diagnosis 1, 2

The American College of Cardiology recommends palpating pedal pulses bilaterally and documenting findings to assess vascular status 6, 7
The American Heart Association suggests measuring ankle-brachial index (ABI) immediately, with critical thresholds requiring urgent vascular referral including ABI <0.5 or ankle pressure <50 mmHg 6, 7
The Society for Vascular Surgery recommends obtaining toe pressures and transcutaneous oxygen pressure (TcPO2) if available, with toe pressure <30 mmHg or TcPO2 <25 mmHg indicating critical ischemia 6
The American College of Surgeons recommends referring urgently to vascular surgery if any of these critical thresholds are met, as revascularization must precede definitive wound healing 6, 7, 8

The Infectious Diseases Society of America recommends surgical debridement of infected bone if feasible, and culture-directed IV antibiotics for a minimum of 4-6 weeks 1, 2
The American College of Infectious Diseases suggests considering chronic suppressive oral antibiotics if complete surgical excision is not possible 4, 5

The Society for Vascular Surgery recommends urgent revascularization (endovascular or surgical bypass) as a priority over prolonged antibiotic therapy 6, 7, 8
The American College of Cardiology suggests not delaying revascularization in favor of medical management alone 8

The American Diabetes Association recommends considering advanced wound therapies, such as bioengineered skin equivalents or cellular therapies, if the wound fails to show ≥50% reduction in size after 4 weeks of optimal management 9
The American College of Infectious Diseases suggests considering negative pressure wound therapy or hyperbaric oxygen therapy for refractory wounds 9, 2, 6, 7

The Infectious Diseases Society of America recommends not continuing empiric antibiotics indefinitely without addressing underlying pathology (osteomyelitis or vascular disease) 1, 2
The American College of Infectious Diseases suggests not relying on superficial wound swabs, as they frequently grow colonizing organisms rather than true pathogens 4, 5, 6
The Society for Vascular Surgery recommends not delaying vascular assessment and intervention in non-healing post-traumatic wounds 6, 7
