What underlying complication of diabetes most commonly leads to Charcot neuroarthropathy?

Peripheral neuropathy

100

What laboratory marker is commonly elevated in cellulitis? 

ESR/CRP

100

What imaging study is usually obtained first when evaluating a swollen diabetic foot?

Xray

100

What is the single most important initial treatment for acute Charcot foot?

Offloading/ non-weight bearing

100

How often should patients with diabetic neuropathy inspect their feet?

Daily 

200

Which part of the foot is most commonly affected by Charcot arthropathy?

The midfoot (tarsometatarsal/Lisfranc joints)

200

A diabetic patient has a plantar ulcer that probes to bone. What diagnosis should be suspected?

Osteomyelitis 

200

True or False:

A normal X-ray rules out acute Charcot foot.

False

200

Which specialty is primarily responsible for surgical correction of Charcot deformity?

Podiatric surgery (Orthopedic foot and ankle surgery also acceptable.)

200

Name one symptom that should prompt immediate medical evaluation after foot surgery.

  • Fever
  • Drainage
  • Increased redness
  • Increased swelling
  • Foul odor
  • Severe pain
  • Wound opening
300

Patients with Charcot foot often report surprisingly little pain despite severe bony destruction. Why?

Peripheral sensory neuropathy reduces pain perception.

300

A diabetic patient with cellulitis is started on antibiotics, but the foot remains warm, swollen, and unstable. What underlying condition should be suspected?

Charcot neuroarthropathy

300

Which imaging modality is most sensitive for detecting early Charcot changes?

MRI

300

Name four members of the multidisciplinary team commonly involved in caring for a patient with Charcot foot.

  • Primary care
  • Podiatry
  • Endocrinology
  • Infectious disease
  • Physical therapy
  • Wound care
  • Nutrition
  • Vascular surgery
  • Orthopedic surgery
  • Diabetes educator
300

Why is strict non-weight-bearing crucial after Charcot surgery?

To prevent collapse, hardware failure, delayed healing, and recurrent deformity.

400

Name two clinical findings that make you suspect acute Charcot rather than a simple ankle sprain.

  • Warm foot
  • Swollen foot
  • Erythema
  • Minimal pain
  • Temperature difference 
  • Diabetes with neuropathy
400

Name two findings on MRI that favor osteomyelitis over Charcot arthropathy.

  • Bone: Cortical destruction, Focal marrow loss
  • Infection: Sinus tract, Abscess
400

Name one classic radiographic finding of Charcot arthropathy.

  • Fragmentation
  • Joint subluxation
  • Midfoot collapse
  • Disorganization
  • Sclerosis
  • Debris
400

What surgical device is commonly used to stabilize severe Charcot deformities while minimizing internal hardware placement?

External fixation

400

Name three strategies patients can use to reduce future diabetic foot complications.

  • Daily foot inspections
  • Glycemic control
  • Appropriate footwear
  • Smoking cessation
  • Routine podiatry visits
  • Medication adherence
  • Avoid walking barefoot
500

What classic foot deformity develops as Charcot disease progresses?

Rocker-bottom deformity

500

What rapidly progressive soft tissue infection requires immediate surgical intervention and is often associated with subcutaneous gas?

Necrotizing fasciitis 

500

Why can MRI sometimes have difficulty distinguishing Charcot arthropathy from osteomyelitis?

Because both can produce bone marrow edema, soft tissue edema, and bone destruction 

500

Name one antibiotic commonly used for severe diabetic foot infections requiring MRSA coverage.

Vancomycin 

500

Name five key discharge teaching points for a patient following Charcot reconstruction.

  • Maintain strict non-weight-bearing
  • Inspect feet daily
  • Monitor blood glucose
  • Wear prescribed offloading device/footwear
  • Take medications as prescribed
  • Watch for infection
  • Attend follow-up appointments
  • Elevate the extremity
  • Protect external fixator/pin sites (if applicable)
  • Avoid tobacco use
