How to help out the foot folk Suspected infection… Open wound: tissue quality Skin color: cellulitis, purulence, fluctuance Edema Vital Sings/abnormal labs Severity Send to ED and/or call ortho consult 719-2475 call podiatry for advise/urgency of scheduling E-Referral if non-acute Order: Plain films, MRI NOT NECESSARY CBC with diff, Sed Rate, CRP, Complex Metabolic Panel
Neuropathic Osteoarthropathy AKA Charcot Causes: Peripheral neuropathy Unrecognized trauma Inflammation Characteristics: Joint dislocation Pathological fractures Collapse of the foot and ankle Often misdiagnosed for acute cellulitis or sprain Chronic Charcot can cause rocker bottom deformity- ARF ulceration d/t biomechanical abnormality ACUTE CHARCOT REQUIRES PROMPT REFERRAL
Peripheral Vascular Disease Blood flow is IMPARATIVE to wound healing No blood flow…send em to gen surg/vascular High risk for gangrene and limb loss Diminished blood flow Moderate risk for gangrene Super slow healing of ulcerations Venous Stasis Ulcers / Arterial Ulcers Treatment Unna Boot Compression Stockings Vascular Consult CT angiogram with bilateral leg runoffs/ ABIs
Case Study #2 30 yr old IDDM with h/o ulceration, charcot, has current ulceration Medically compromised: obesity, HD, anemia, peripheral vascular disease Comes to clinic with 2 large plantar ulcers, malodorous, recent multiple hospitalizations, cellulitis, on oral abx.

Needs to get supplements at Dialysis, wound vac vs packed woundcare Needs e-referral for HAH for wound vac changes-denies due to ambulatory status Now what?
Ulcer Treatment Guidelines (2) Debridment of necrotic tissue Surgical, Mechanical, Autolytic, Enzymatic Pressure Reduction Healing sandals, contact casting, offloading Wound care Dressings, Hygiene Infection Control Cover MRSA if no culture taken, r/o osteomyelitis (xray vs MRI)?? Vascular Palpable pulses Medical management Good glycemic control Good blood pressure management Renal status Reduce the risk of recurrence Regular podiatric care Education Protective footwear
Admission vs Outpatient? An admission is determined by Extent of cellulitis Vital Sign abnormality, abnormal labs Lymphangiitis Soft tissue necrosis, fluctuance, odor, gangrene, risk of osteomyelitis I&D, boney excision, extent of infection: limb loss risk? Less threatening Superficial to full thickness, no bone involved Medically stable Mild erythema, warmth, edema In office sharps debridement, boney excision
Infection….what are we treating? In our practice we treat a Diabetic with a non-identified bacteria with a broad spectrum antibiotic that will cover for osteomyelitis and MRSA Septra DS Clindamycin Once a specimen is obtained we then will change the treatment plan if necessary Frequent office visits Helpful if PCP is involved with medical management with co- morbidities: renal, cardiac, endocrine….
Wound Care- Where? 4C: frequent dressing changes under the watchful eyes of Trish McCarthy and Ardene Ballonado NPs and the staff Can the patient do it? Back to Podiatry weekly/ q 2 weeks for sharps debridments and reassessments until closure
