Question 52: 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 forefoot drives the hindfoot varus and soft tissue correction may suffice (Correct answer)
The hindfoot deformity is fixed and requires calcaneal osteotomy
Subtalar arthrodesis is mandated
Tibialis posterior transfer should be the primary procedure

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 53: Which factor most significantly impairs postoperative wound healing in foot and ankle surgery patients?

Patient age over 40
Vegetarian diet
Female gender
Tobacco smoking (Correct answer)

Correct answer: Tobacco smoking

Tobacco smoking causes peripheral vasoconstriction and tissue hypoxia, significantly impairing wound healing and increasing the risk of infection and dehiscence.

Question 54: What is the correct technique for removing a contaminated surgical gown to prevent self-contamination?

Pull the gown off by grasping the clean inner surface
Remove gloves first, then pull the gown off over the head
Have a non-scrubbed team member cut the gown off
Roll the outside of the gown inward and away from the body before removing (Correct answer)

Correct answer: Roll the outside of the gown inward and away from the body before removing

Rolling the gown outward while removing it keeps contaminated surfaces contained and away from the wearer's skin and clothing.

S1, tibial nerve (Correct answer)
L4, deep peroneal nerve
S2, sural nerve
L5, superficial peroneal nerve

Correct answer: S1, tibial nerve

Ankle plantarflexion is primarily an S1 function mediated by the tibial nerve through the gastrocnemius-soleus complex.

Question 65: During an initial assessment, what should be documented first?

Chief complaint and history of present illness (Correct answer)
Discharge planning notes
Family social history only
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 66: What happens if a surgeon fails to meet the requirements for the Maintenance of Certification (MOC) by the deadline?

The surgeon is required to complete additional residency training
The surgeon is automatically disqualified from the ABFAS program
The surgeon’s certification becomes inactive or suspended (Correct answer)
The surgeon must take a full recertification exam

Correct answer: The surgeon’s certification becomes inactive or suspended

Failing to meet the requirements for the Maintenance of Certification (MOC) by the deadline results in the surgeon's certification becoming inactive or suspended. This measure ensures that only those who continuously demonstrate their commitment to ongoing education and competency retain their board-certified status, protecting public trust and patient safety.

Question 67: What is the correct sequence for a physical assessment?

Percussion, auscultation, inspection, palpation
Inspection, palpation, percussion, auscultation (Correct answer)
Palpation, inspection, auscultation, percussion
Auscultation, percussion, palpation, inspection

Correct answer: Inspection, palpation, percussion, auscultation

The standard physical assessment sequence is inspection (visual), palpation (touch), percussion (tapping), and auscultation (listening).

Question 68: A patient taking metformin undergoes a procedure requiring IV contrast. Why should metformin be held perioperatively?

Metformin sensitizes the kidney to contrast-induced free radical damage
Contrast nephropathy can reduce metformin clearance, increasing lactic acidosis risk (Correct answer)
Contrast activates metformin hepatic metabolism leading to toxicity
Metformin inhibits renal excretion of contrast dye

Correct answer: Contrast nephropathy can reduce metformin clearance, increasing lactic acidosis risk

Contrast-induced nephropathy reduces renal clearance of metformin, causing accumulation and increasing the risk of potentially fatal lactic acidosis.

Question 69: A patient asks their foot and ankle surgeon not to discuss their diagnosis with their spouse, who is present at the appointment. The surgeon must:

Respect the patient's confidentiality and not disclose without their permission (Correct answer)
Override this request since the spouse is listed as emergency contact
Document the patient's request but share essential details with the spouse anyway
Disclose general information to the spouse to facilitate home care

Correct answer: Respect the patient's confidentiality and not disclose without their permission

Patients control who has access to their health information; the spouse's presence does not grant them the right to receive clinical details.

Question 70: What is the primary purpose of fellowship programs in foot and ankle surgery?

To allow surgeons to gain specialized knowledge and advanced skills in complex surgeries (Correct answer)
To introduce surgeons to administrative roles in healthcare
To prepare surgeons for certification exams
To provide surgeons with basic training in foot and ankle procedures

Correct answer: To allow surgeons to gain specialized knowledge and advanced skills in complex surgeries

Fellowship programs in foot and ankle surgery are designed to provide post-residency surgeons with intensive, subspecialized training. This allows them to develop advanced expertise and master complex surgical techniques for intricate foot and ankle conditions, going beyond the general scope of residency training.

Question 71: During a postoperative visit, the patient mentions feeling depressed and isolated due to prolonged non-weight-bearing recovery. What is the most appropriate surgeon response?

Recommend the patient join online support groups for surgical recovery
Reassure the patient that physical recovery is on track and the emotional state will improve
Acknowledge the psychosocial burden, screen for depression, and coordinate with the patient's primary care team or mental health resources (Correct answer)
Advise the patient to focus on the positive aspects of their recovery progress

Correct answer: Acknowledge the psychosocial burden, screen for depression, and coordinate with the patient's primary care team or mental health resources

Surgical recovery affects mental health; screening and coordinating mental health support is part of comprehensive patient care.

Question 72: A patient requires excision of a ganglionic cyst on the dorsum of the foot. Which anatomical structure must be carefully identified and preserved during this procedure?

Dorsalis pedis artery and deep peroneal nerve (Correct answer)
Posterior tibial artery
Extensor digitorum brevis muscle
Flexor hallucis longus tendon

Correct answer: Dorsalis pedis artery and deep peroneal nerve

The dorsalis pedis artery and deep peroneal nerve run on the dorsum of the foot and are at risk during dorsal ganglion excision.

Question 73: What should a ABFAS professional do when facing a conflict of interest?

Proceed as normal without disclosure
Disclose the conflict and recuse if necessary (Correct answer)
Delegate to an unqualified colleague
Ignore it if no one notices

Correct answer: Disclose the conflict and recuse if necessary

Transparency through disclosure and recusal when appropriate maintains professional integrity and public trust.

Question 74: What does a positive Thompson test indicate in the context of postoperative foot and ankle care?

Compartment syndrome is developing
Metatarsal stress fracture
Plantar fasciitis recurrence
Achilles tendon rupture or re-rupture (Correct answer)

Correct answer: Achilles tendon rupture or re-rupture

A positive Thompson test — absence of plantar flexion when the calf is squeezed with the patient prone — confirms Achilles tendon rupture or re-rupture postoperatively.

Question 75: 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?

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
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)

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 76: What is the clinical significance of adding epinephrine to a local anesthetic solution for digital nerve blocks in the toes?

It is contraindicated due to risk of digital ischemia (Correct answer)
It increases the speed of onset
It is safe and prolongs duration by reducing systemic absorption
It prevents systemic toxicity in all patients

Correct answer: It is contraindicated due to risk of digital ischemia

Epinephrine-containing local anesthetics are contraindicated for digital blocks in the toes due to vasoconstriction risk causing ischemia and potential necrosis of end-arterial structures.

Question 77: Which antifungal agent is used topically for onychomycosis prophylaxis and works by inhibiting ergosterol synthesis?

Nystatin
Terbinafine (Correct answer)
Ciclopirox
Griseofulvin

Correct answer: Terbinafine

Terbinafine inhibits squalene epoxidase, blocking ergosterol biosynthesis and is the topical/oral agent of choice for dermatophyte-caused onychomycosis.

Question 78: A patient presents with a positive Thompson test. Which structure is most likely injured?

Achilles tendon (Correct answer)
Flexor hallucis longus
Posterior tibial tendon
Plantar fascia

Correct answer: Achilles tendon

The Thompson test (calf squeeze test) assesses Achilles tendon continuity; absence of plantarflexion on calf squeeze indicates complete Achilles tendon rupture.

Question 79: Which of the following correctly describes the ABFAS examination timeline relative to fellowship completion?

Candidates typically sit for Part I after completing fellowship training and accumulating required case experience (Correct answer)
Part I must be passed before starting the fellowship
There is no examination requirement — fellowship completion alone grants certification
Part I and Part II may both be taken during fellowship training

Correct answer: Candidates typically sit for Part I after completing fellowship training and accumulating required case experience

Candidates generally sit for the ABFAS Part I examination after completing their fellowship and meeting the required case volume thresholds.

Question 80: During a foot surgery, a tourniquet has been inflated for 90 minutes. Upon deflation, the patient develops hypotension and bradycardia. This presentation is most likely caused by:

Pulmonary embolism from the operative limb
Air embolism from the surgical field
Tourniquet reperfusion syndrome releasing vasodilatory mediators (Correct answer)
Anesthetic agent overdose from absorbed local

Correct answer: Tourniquet reperfusion syndrome releasing vasodilatory mediators

Tourniquet reperfusion syndrome occurs when ischemic metabolites, potassium, and vasodilatory substances are released into systemic circulation upon cuff deflation.

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

The ABFAS Part I Didactic Examination is a computer-adaptive, multiple-choice exam that evaluates clinical knowledge in foot and ankle surgery acquired during podiatric medical school and residency training. It assesses competency across surgical procedures, diagnostic imaging, perioperative management, complications, and general medicine.
