How to Build Your ABOS Part II Case List: What to Include and What to Leave Out

Most candidates think about their case list wrong. They treat it like a highlight reel — a curated set of their best cases, polished and cherry-picked. Then the collection period ends, case selectors do their work, and suddenly the candidate is defending a case they never expected to talk about.

Here's the mental model that actually works: your case list is the menu case selectors choose from. You don't get to decide which 12 cases you defend. Someone else does. Which means every case you submit has to be exam-ready, because you can't control which ones get picked.

That single reframe changes how you build the list from day one of the collection period.

You're Not Building a Highlight Reel

Candidates who try to game the list by submitting only easy, clean, uncomplicated cases run into two problems.

First, case selectors are looking for breadth. They want to see the range of what you do. A list that looks suspiciously homogenous — all the same approach, all clean outcomes, all the same diagnosis — tells them you're hiding something or you don't have the volume they expect. Neither is a good signal going into an oral exam.

Second, gaming the list means the cases you exclude are often the ones you'd actually learn the most from defending. Complications, revisions, difficult decisions — those are the cases where examiners can see how you think. Clean cases don't give you much room to demonstrate judgment. The messy ones do.

This is counterintuitive, but honest management of a complication is a strength on the oral boards, not a weakness. What kills candidates isn't having bad outcomes. It's hiding them, rationalizing them, or failing to demonstrate that they recognized the problem and responded appropriately.

What to Include

Include cases that reflect the actual scope of your practice. If you do trauma, show trauma. If you do arthroplasty, show arthroplasty. Don't try to present yourself as a surgeon you're not — examiners can read a practice pattern in thirty seconds, and any mismatch between your list and your stated practice is going to generate uncomfortable questions.

Specifically, lean into:

• Cases with clear decision points. Cases where you chose between two reasonable options and can articulate why. These let you demonstrate framework thinking, which is what the exam is actually testing.
• Cases where you consulted appropriately. Showing you used the right specialists, imaging, and workup reinforces the picture of a thoughtful, humble surgeon.
• Cases with complications you managed well. Infection, wound issues, hardware problems, revisions. What matters is that you recognized the problem early and responded. Following the patient closely after a complication is one of the strongest signals you can send on the exam.
• Cases that followed conservative care failure. You want a paper trail showing you tried non-operative management first — therapy, bracing, injections, time. Operating on everyone who walks in is a red flag.

What to Leave Out

Leave out cases where you genuinely cannot reconstruct what happened. If the documentation is thin, the imaging is missing, or you can't remember your own reasoning, that case is a liability on the list. Examiners will find the gaps. You're better off not defending a case you can't defend.

Leave out cases where the indication is genuinely shaky and you know it. There's a difference between a defensible complication and an indefensible decision. A complication in a well-indicated case is a teaching moment. An operation you shouldn't have done is a hole you can't dig out of — especially if the documentation makes the weak indication obvious.

Leave out cases where financial optics look bad. Candidates in private practice should be especially careful about this. Anything that could be read as money-motivated — operating on marginal indications, unusually aggressive surgical plans, patterns that look like volume-chasing — will draw scrutiny. The examiners want to see an ethical, patient-centered surgeon.

Documentation Is the Load-Bearing Wall

Here's the part candidates underestimate until it's too late: the documentation on every submitted case has to be exam-ready, not just the ones you think will get picked.

Remember that during the exam itself, one examiner is leading the conversation while a second examiner is quietly reviewing your uploaded records. If that second examiner finds inconsistencies — a note that contradicts your presentation, an operative report that's missing key details, coding that doesn't match what you actually did — they will surface those gaps. And those surfaced gaps become the questions that derail candidates.

This means documentation quality is a case-list strategy issue, not just an administrative issue. Every case you submit should have a complete operative report, clean imaging, a consult note (if applicable), and follow-up documentation that tracks the actual clinical course. If any of that is incomplete, you're handing the examiners a problem to find.

Build the List as You Operate

The single biggest mistake candidates make is waiting until the end of the collection period to assemble the list. That's when the documentation gets sloppy, the memory fades, and the scramble begins.

The candidates who do this well build the list in real time. Every case that could belong on the list gets flagged the week it happens. The operative note gets dictated with board-level detail. The imaging gets saved. A brief summary gets written while the case is fresh. When the collection period closes, they're refining — not reconstructing.

This also means coordinating with the people around you. Talk to your coders and billers early. Make sure the diagnosis and procedure codes on your cases actually reflect what you did — because those codes are what the ABOS systems see, and mismatches create confusion you don't want to explain under oath. Build the relationship with your documentation team before you need them, not after.

The Mindset Shift

The candidates who struggle with the case list treat it like a one-time submission. The candidates who do well treat it like a rolling portfolio they maintain throughout the collection period. Every week, a few more cases get cleaned up and filed away. By the time the deadline arrives, the work is already done.

And because every case on the list is exam-ready, it doesn't matter which 12 the selectors pick. That's the goal. You want to walk into the exam room indifferent to the selection — because any case they chose would be one you're prepared to defend.

That's what a well-built case list gives you: optionality. And on an exam where you don't control much, optionality is the closest thing to control you can buy yourself.
