Part II (Oral Examination): Case-Based Reasoning and Communication
What the oral exam tests
The Part II oral examination presents clinical scenarios and probes judgment, not recall. Examiners want a structured, prioritized plan delivered aloud: history and exam findings, differential, workup, definitive management, and complications. The format rewards candidates who narrate their reasoning and acknowledge uncertainty rather than guessing.
Concepts you must command
Know the decision points for each major region: when to operate versus observe (e.g., displaced femoral neck fracture in an elderly patient - arthroplasty, not fixation), how to select implant and approach, and the expected complications and their timelines (fat embolism, nonunion, avascular necrosis, infection). Be fluent in pediatric deformity, adult reconstruction indications, and trauma damage-control principles. Understand consent, capacity, and disclosure of complications - ethics questions appear and are scored on communication.
Traps to expect
Examiners deliberately introduce ambiguity or a changing clinical picture mid-case; adapt rather than defend an initial answer. Do not skip the physical exam or the "what else would you ask" prompt. Avoid jumping to surgery before establishing diagnosis and nonoperative alternatives. A common trap is ignoring the patient's goals and comorbidities. Silence is penalized - think aloud.
Rule of thumb
Use a consistent scaffold for every case: differential → confirmatory test → nonoperative options → operative indication → implant/approach → complications and follow-up. This structure prevents omissions and signals organized judgment.
Worked example
A 70-year-old with a displaced femoral neck fracture: state the diagnosis, note the high risk of avascular necrosis and nonunion with fixation, and commit to arthroplasty (hemiarthroplasty or total hip depending on pre-injury function), then name dislocation, infection, and thromboembolism as complications. Naming the reasoning behind each choice is what earns credit.
