ABFAS American Board of Foot and Ankle Surgery Part I Didactic Examination — Questions and Answers

Question 1: In electronic health record systems used in podiatric surgery, an 'audit trail' primarily serves to:

Generate automatic CPT codes from clinical notes
Track who accessed or modified records and when (Correct answer)
Encrypt records for HIPAA compliance
Speed up billing workflows

Correct answer: Track who accessed or modified records and when

EHR audit trails log every access and modification event with user identity and timestamp, supporting both compliance monitoring and medicolegal review.

Question 2: A patient refuses recommended surgery for a displaced fifth metatarsal fracture, preferring conservative management despite being informed of risks. What is the most appropriate response?

Persuade the patient to reconsider by emphasizing worst-case outcomes
Discharge the patient from the practice for non-compliance
Consult psychiatry to evaluate the patient's decision-making capacity
Document the refusal, ensure the patient understands the consequences, and respect the autonomous decision (Correct answer)

Correct answer: Document the refusal, ensure the patient understands the consequences, and respect the autonomous decision

Patients with decision-making capacity have the right to refuse treatment; the physician must document the discussion and respect the decision.

Question 3: Which of the following best reflects the interdependence between CPME accreditation and ABFAS board certification for fellowship-trained candidates?

CPME and ABFAS are completely separate with no shared requirements
CPME accreditation of the training program is a prerequisite for ABFAS to recognize a candidate's fellowship training (Correct answer)
ABFAS grants certification independent of CPME accreditation status
CPME certification replaces ABFAS board certification

Correct answer: CPME accreditation of the training program is a prerequisite for ABFAS to recognize a candidate's fellowship training

ABFAS requires that fellowship training occur at a CPME-accredited program; without this accreditation, the training is not recognized for certification eligibility.

Question 4: A patient with poorly controlled type 2 diabetes is requesting elective hallux valgus surgery. The surgeon determines the patient is not a good surgical candidate at this time. How should this be communicated?

Defer the conversation to the primary care physician who manages the diabetes
Decline the surgery without providing a reason to avoid a difficult conversation
Explain clearly that surgery is not advisable now, outline the specific metabolic targets needed, and describe a pathway to becoming a candidate (Correct answer)
Offer surgery with the caveat that the patient understands the elevated risk

Correct answer: Explain clearly that surgery is not advisable now, outline the specific metabolic targets needed, and describe a pathway to becoming a candidate

Providing specific, actionable criteria for candidacy empowers the patient and maintains the therapeutic relationship despite a disappointing decision.

Question 5: Which local anesthetic has the longest duration of action and is most appropriate for postoperative nerve blocks in foot surgery?

Bupivacaine (Correct answer)
Prilocaine
Lidocaine
Mepivacaine

Correct answer: Bupivacaine

Bupivacaine provides 8-12+ hours of analgesia due to its high lipid solubility and protein binding, making it ideal for postoperative nerve blocks.

Question 6: A patient presents with suspected Lisfranc injury and appears frightened after searching symptoms online. The surgeon confirms a Lisfranc ligament disruption on imaging. How should the diagnosis be delivered?

Use clinical terminology to convey the seriousness and establish professional credibility
Acknowledge the patient's prior research, confirm the diagnosis in plain language, explain implications and treatment options, and allow time for questions (Correct answer)
Downplay severity initially to minimize anxiety before subsequent visits where full details will be provided
Lead with the surgical treatment plan to give the patient a sense of control over the diagnosis

Correct answer: Acknowledge the patient's prior research, confirm the diagnosis in plain language, explain implications and treatment options, and allow time for questions

Meeting the patient where they are by acknowledging their research, confirming the diagnosis simply, and allowing questions reduces anxiety and builds informed consent readiness.

Question 7: A patient undergoing foot surgery under spinal anesthesia develops hypotension intraoperatively. What is the first-line intervention?

Apply direct pressure to the surgical site
IV fluid bolus and IV ephedrine or phenylephrine (Correct answer)
Administer IV epinephrine 1 mg
Discontinue the spinal anesthetic

Correct answer: IV fluid bolus and IV ephedrine or phenylephrine

Spinal-induced hypotension is managed first with IV fluid bolus and vasopressors such as ephedrine or phenylephrine to restore sympathetic tone.

Question 8: A patient with chronic kidney disease (CrCl 25 mL/min) requires antibiotic therapy. Which agent requires the most significant dose reduction?

Cephalexin (Correct answer)
Clindamycin
Metronidazole
Doxycycline

Correct answer: Cephalexin

Cephalexin is primarily renally excreted; dose intervals must be extended in renal impairment to prevent accumulation and toxicity.

Question 9: A 16-year-old athlete presents with heel pain worse in the morning and with activity. Point tenderness is elicited at the posterior calcaneal apophysis. What is the most likely diagnosis?

Plantar fasciitis
Sever's disease (calcaneal apophysitis) (Correct answer)
Insertional Achilles tendinopathy
Haglund's deformity

Correct answer: Sever's disease (calcaneal apophysitis)

Sever's disease is apophysitis of the calcaneal growth plate, common in active adolescents, presenting with posterior heel pain and apophyseal tenderness.

Question 10: For which postoperative indication is the Ilizarov circular external fixation technique most commonly used in foot and ankle surgery?

Limb lengthening and gradual deformity correction (Correct answer)
Wound debridement
Peripheral nerve repair
Tendon transfer stabilization

Correct answer: Limb lengthening and gradual deformity correction

The Ilizarov technique uses circular external fixation and controlled distraction osteogenesis for limb lengthening and gradual deformity correction after surgery.

Question 11: Which of the following describes the normal foot pronation-supination axis of the subtalar joint?

Oblique axis passing medially, anteriorly, and superiorly (Correct answer)
Horizontal transverse axis
Purely sagittal axis
Purely vertical axis

Correct answer: Oblique axis passing medially, anteriorly, and superiorly

The subtalar joint axis is oblique, passing medially, anteriorly, and superiorly at approximately 16° from vertical and 42° from horizontal.

Question 12: During an initial assessment, what should be documented first?

Discharge planning notes
Family social history only
Chief complaint and history of present illness (Correct answer)
Insurance information

Correct answer: Chief complaint and history of present illness

The chief complaint and history of present illness establish the reason for the visit and provide context for the examination.

Question 13: Which antibiotic is added to bone cement during diabetic foot osteomyelitis surgery to achieve local high-concentration delivery while minimizing systemic toxicity?

Oral amoxicillin powder
Vancomycin or tobramycin (Correct answer)
Rifampin-only impregnated cement
Intravenous cefazolin mixed directly

Correct answer: Vancomycin or tobramycin

Vancomycin and tobramycin are heat-stable antibiotics commonly mixed into polymethylmethacrylate (PMMA) bone cement for local elution against gram-positive and gram-negative organisms.

Question 14: A surgeon leaves a voicemail informing a patient that their biopsy result showed a benign lesion. The patient later states they never received the message. What is the most appropriate process improvement?

Use email as the primary method for delivering biopsy results going forward
Leave a second voicemail and document the date and time in the medical record
Have the patient sign a form acknowledging they are responsible for retrieving messages
Implement a closed-loop communication protocol requiring documented patient acknowledgment of all result communications (Correct answer)

Correct answer: Implement a closed-loop communication protocol requiring documented patient acknowledgment of all result communications

Closed-loop communication protocols ensure results are received and understood, reducing the risk of patients missing critical clinical information.

Question 15: Which blood supply is most critical to the talus and most commonly disrupted in talar neck fractures?

Dorsalis pedis artery
Peroneal artery
Artery of the tarsal canal (branch of posterior tibial artery) (Correct answer)
Anterior tibial artery

Correct answer: Artery of the tarsal canal (branch of posterior tibial artery)

The artery of the tarsal canal, a branch of the posterior tibial artery, is the primary blood supply to the talar body and is frequently disrupted in talar neck fractures, risking avascular necrosis.

Question 16: A patient develops hematoma under a split-thickness skin graft used for a foot wound. What is the immediate management?

Remove the graft and apply antibiotic ointment
Apply additional compression dressing and observe
Aspirate or make small incisions to evacuate the hematoma (Correct answer)
Initiate hyperbaric oxygen therapy

Correct answer: Aspirate or make small incisions to evacuate the hematoma

Hematoma beneath a skin graft prevents revascularization; prompt evacuation via aspiration or small incisions salvages graft adherence.

Question 17: The 'three-day payment window' rule in Medicare requires that outpatient services provided within how many days before inpatient admission must be bundled with the inpatient claim?

1 day
7 days
5 days
3 days (Correct answer)

Correct answer: 3 days

The Medicare three-day payment window bundles outpatient services provided within 3 days of inpatient admission into the inpatient DRG payment.

Question 18: Which clinical test is used to diagnose posterior tibial tendon dysfunction by assessing single-limb heel rise?

Mulder's click test
Thompson test
Drawer test
Single-heel rise test (Correct answer)

Correct answer: Single-heel rise test

The single-heel rise test assesses posterior tibial tendon function; inability to rise onto the toes on the affected limb suggests significant PTT dysfunction.

Question 19: Which radiographic sign indicates avascular necrosis of the talus following a fracture?

Increased talar neck cortical density acutely
Widening of the ankle mortise
Periosteal new bone formation
Hawkins sign (subchondral lucency at 6–8 weeks) (Correct answer)

Correct answer: Hawkins sign (subchondral lucency at 6–8 weeks)

The Hawkins sign—subchondral lucency seen at 6–8 weeks post-fracture—indicates disuse osteopenia and is a positive prognostic sign that blood supply is intact.

Question 20: A fellowship candidate applying for ABFAS board certification must have completed a residency program approved by which entity?

CPME (Correct answer)
American College of Foot and Ankle Surgeons (ACFAS)
ABFAS directly
State podiatric medical board

Correct answer: CPME

ABFAS requires completion of a CPME-approved residency as a prerequisite for board certification eligibility.

Question 21: A patient with rheumatoid arthritis presents with forefoot deformity. Which clinical finding is most characteristic of RA affecting the MTP joints?

Fibular deviation of all toes with plantar fat pad migration (Correct answer)
Dorsal corns over the proximal interphalangeal joints
Rigid hammertoe deformity of the second toe only
Isolated hallux valgus with normal lesser toes

Correct answer: Fibular deviation of all toes with plantar fat pad migration

Rheumatoid arthritis characteristically causes fibular/lateral deviation of all lesser toes with distal migration of the plantar fat pad due to MTP joint synovitis and capsular destruction.

Question 22: A podiatric surgeon is treating a patient who is also being treated by another specialist for the same condition. The ethical approach is to:

Assume the other specialist will handle all aspects of treatment
Proceed independently without coordinating to maintain patient confidentiality
Discharge the patient to avoid duplication of care
Communicate and coordinate care with the other provider with the patient's consent (Correct answer)

Correct answer: Communicate and coordinate care with the other provider with the patient's consent

Coordinated care with appropriate consent improves patient outcomes and reflects ethical standards of interprofessional practice.

Question 23: Which clinical finding suggests possible deep vein thrombosis (DVT) in a postoperative foot and ankle patient?

Localized wound erythema only
Decreased ankle range of motion
Calf pain, swelling, and pain with passive dorsiflexion (Correct answer)
Wound dehiscence with serous drainage

Correct answer: Calf pain, swelling, and pain with passive dorsiflexion

Calf pain, swelling, and pain with passive dorsiflexion (Homan's sign) are classic indicators of potential DVT and require urgent further evaluation.

Question 24: Which ethical obligation applies when a foot and ankle surgeon makes an intraoperative error that may affect the patient's outcome?

Only disclose if the patient develops complications that require additional treatment
Document the error in the chart but do not discuss it with the patient
Consult legal counsel before deciding whether to inform the patient
Disclose the error to the patient and discuss the implications for their care (Correct answer)

Correct answer: Disclose the error to the patient and discuss the implications for their care

Ethical practice requires transparent disclosure of medical errors to patients, regardless of whether complications have yet manifested.

Question 25: What is the primary purpose of the Maintenance of Certification (MOC) process for ABFAS?

To allow surgeons to specialize in new areas of foot and ankle surgery
To promote professional development and ensure competency (Correct answer)
To reduce the workload of certified surgeons
To prepare surgeons for leadership roles

Correct answer: To promote professional development and ensure competency

The Maintenance of Certification (MOC) process for ABFAS is designed to ensure that certified surgeons continually engage in activities that promote their professional development and demonstrate ongoing competency. It goes beyond initial certification by requiring continuous learning, self-assessment, and periodic evaluation to uphold high standards of patient care.

Question 26: During the Coleman block test, placing a 1-inch block under the lateral forefoot of a patient with a cavovarus deformity reveals a flexible hindfoot varus. What does this finding indicate?

The hindfoot deformity is fixed and requires calcaneal osteotomy
The forefoot drives the hindfoot varus and soft tissue correction may suffice (Correct answer)
Tibialis posterior transfer should be the primary procedure
Subtalar arthrodesis is mandated

Correct answer: The forefoot drives the hindfoot varus and soft tissue correction may suffice

A flexible hindfoot varus on Coleman block test indicates that forefoot-driven deformity is the primary problem, allowing hindfoot correction with forefoot procedures alone.

Question 27: What is the treatment of choice for systemic local anesthetic toxicity (LAST) causing cardiovascular collapse?

Calcium gluconate infusion
High-dose epinephrine infusion
Intravenous lipid emulsion (Intralipid 20%) (Correct answer)
Sodium bicarbonate bolus

Correct answer: Intravenous lipid emulsion (Intralipid 20%)

Intravenous lipid emulsion therapy (Intralipid 20%) acts as a 'lipid sink,' sequestering lipophilic local anesthetics away from cardiac and CNS tissues in LAST emergencies.

Question 28: Which statement correctly describes the scope of ABFAS jurisdiction compared to the American Podiatric Medical Association (APMA)?

ABFAS and APMA are the same organization with different names
APMA accredits residency programs while ABFAS represents podiatric surgeons politically
ABFAS governs podiatric medical education, while APMA handles board examinations
ABFAS is a certifying board focused on surgical competency assessment, while APMA is a professional membership and advocacy organization (Correct answer)

Correct answer: ABFAS is a certifying board focused on surgical competency assessment, while APMA is a professional membership and advocacy organization

ABFAS focuses exclusively on certifying surgical competency, whereas APMA serves as the professional association advocating for podiatric physicians broadly.

Question 29: What type of cases are primarily documented in a surgical case log submitted to ABFAS for certification purposes?

Cases where the candidate served as primary surgeon, assistant, or observer
Cases reviewed in grand rounds presentations
Only cases where the candidate was the attending surgeon (Correct answer)
Only emergency surgical cases

Correct answer: Only cases where the candidate was the attending surgeon

ABFAS requires case logs to document procedures where the candidate was the primary operating surgeon to demonstrate hands-on surgical competency.

Question 30: Which imaging documentation is specifically required in ABFAS case submissions to demonstrate rearfoot alignment correction?

Nuclear bone scan before and after surgery
Weight-bearing radiographs with angular measurements (Correct answer)
CT angiography of the foot
MRI with gadolinium contrast

Correct answer: Weight-bearing radiographs with angular measurements

ABFAS requires weight-bearing radiographs with documented angular measurements to objectively demonstrate preoperative deformity and postoperative correction.

Question 31: A patient with a suspected stress fracture of the second metatarsal has normal plain radiographs. Which imaging modality should be ordered next for early diagnosis?

CT scan
MRI (Correct answer)
Diagnostic ultrasound
Bone scintigraphy

Correct answer: MRI

MRI is the preferred modality for early stress fracture diagnosis, detecting bone marrow edema within days of symptom onset, compared to the 2–3 week delay for radiographic changes.
