How to Prepare for ABOS Part II (Oral)

Stepping up to the American Board of Orthopaedic Surgery (ABOS) Part II oral examination is a defining milestone in any surgeon’s career. Unlike standardised written tests, this viva is uniquely centred on your own surgical practice, demanding that you confidently defend the clinical decisions you made on specific patients. Success here is less about rote memorisation and far more about demonstrating mature, comprehensive surgical judgement.

Curating a Defensible Case List

The foundation of your oral examination is the case list you submit. As you progress from medical school through your early surgical training—passing through foundation or internship years, core surgical training, and higher specialty registrar posts—you will inevitably accumulate a diverse logbook of procedures. When selecting cases for the ABOS Part II, you must choose wisely. The goal is not to select only the perfectly flawless, straightforward operations, nor should you artificially pad your list with incredibly complex surgeries where you faced disastrous complications.

Instead, aim for a balanced portfolio that accurately reflects your typical practice and highlights your ability to manage common complications gracefully. For every case you submit, be entirely honest with yourself about why you chose it. You should select cases where you managed a challenging intraoperative event, navigated a difficult postoperative issue, or made a sound call under conditions of clinical uncertainty. Examiners are highly experienced surgeons; they can quickly spot a trainee who is trying to hide behind a heavily curated, sanitised list of perfect outcomes. Choose the cases that you know inside and out, including the specific anatomical nuances and the exact steps of your surgical approach.

Mastering the Details of Your Own Patients

Because the examiners will rigorously quiz you on your own documented cases, you must know your patients better than anyone else in the hospital. You must be fully prepared to justify your exact implant choices, the specific fixation strategies you employed, and your postoperative rehabilitation protocols. Go far beyond simply stating that a fracture was unstable and required plating. Be ready to defend precisely why you chose a specific plate design over an intramedullary device, and articulate why you opted for a particular surgical approach over a viable alternative.

You should also anticipate questions regarding any recognised complications associated with your chosen procedures. If you performed an elective joint replacement, you must be ready to discuss your deep vein thrombosis prophylaxis protocol and your thresholds for blood transfusion. Examiners want to hear clear, logical reasoning that proves your clinical decision-making is both evidence-based and highly practical.

Structuring Your Defence Through Mock Vivas

The most effective way to prepare for the oral format is to simulate the examination environment as closely and as frequently as possible. Gather your consultant supervisors, senior peers, or fellow senior trainees who have already successfully navigated professional fellowship exams. Sit them down in a quiet room, present your cases orally, and have them relentlessly probe your clinical reasoning.

When responding to their questions, employ a highly structured approach. A highly effective communication strategy is to state the patient’s primary problem in a single sentence, followed immediately by the surgical indication, your chosen intervention, and the specific outcome. If a complication occurred, address it directly. State clearly what went wrong, why you believe it happened, exactly how you managed it in real time, and—crucially—what you learned from the experience. Taking swift ownership of an adverse event demonstrates profound maturity, whereas making excuses or blaming the operating theatre staff will immediately alienate the examiners.

Navigating the Examination Day Itself

The oral examination day can naturally feel intensely intimidating, but maintaining your composure is absolutely essential to your overall success. The examiners are not trying to trick you; their primary goal is to ensure you are a safe, independent, and thoughtful surgeon who is ready to enter unsupervised practice.

When you sit down, listen very carefully to each question asked. Take a brief, deliberate breath before answering to ensure you fully process what is being asked. If an examiner interrupts you, stop talking immediately and listen closely. An interruption usually signifies that you are heading down the wrong path, or they need you to address a specific, urgent clinical detail that you have glossed over. Do not let this fluster you; simply pivot your thought process and directly address their new concern.

Broadening Your Foundational Knowledge

Finally, while your own submitted case list forms the absolute bedrock of the assessment, the oral examination format allows examiners to extrapolate from your specific cases to test your broader orthopaedic knowledge. Because your career pathway likely included foundational training in general surgery or a broad core surgical rotation before you narrowed your focus to orthopaedics, you are fully expected to retain a solid grasp of general surgical principles.

Be prepared to briefly discuss systemic medical issues, the management of polytrauma, and essential critical care principles. You may also be asked about your broader career trajectory, including any future plans to undertake optional subspecialty fellowships. By demonstrating that your knowledge safely extends beyond the strict confines of your submitted case list, you will project the aura of a well-rounded, highly competent clinician.

Ultimately, the oral examination is simply a professional conversation about the patients you already care for daily. Trust your training, defend your clinical choices with clear logic, and remember that demonstrating safe, reflective practice will always carry the day.
