SnapOrtho Boards 360⁺

One blueprint for both exams

Since 2025 the AAOS Orthopaedic In-Training Examination uses the blueprint developed by the American Board of Orthopaedic Surgery for the Part I certification exam (the "Orthopaedic Subspecialty Version"). It splits the exam into 10 domains and 87 weighted lines. Boards 360+ is organized by that blueprint, so the same map works for the OITE (275 questions) and Part I (328).

• Trauma13.5% · ≈37
• General Principles13% · ≈36
• Pediatrics12% · ≈33
• Hand & Wrist10.5% · ≈29
• Foot & Ankle10% · ≈28
• Sports9.5% · ≈26
• Spine9% · ≈25
• Adult Recon8% · ≈22
• Shoulder & Elbow7.5% · ≈21
• Oncology7% · ≈19

The 2025 change was large: Hip & Knee fell from 19% to 8% (now Adult Reconstruction, arthroplasty and arthritis only), knee ligament and patellofemoral topics moved to Sports, hip and femur fractures moved to Trauma, and Hand rose from 7% to 10.5%. The blueprint marks nine topics that must appear at least once; they are starred on the map.

What the numbers mean

≈ questions

The official blueprint weight multiplied by the exam length. Hand & Wrist is 10.5% of 275 OITE questions, so ≈29. Real exams vary year to year.

Orthobullets questions

SnapOrtho mapped each of 8,159 Orthobullets practice questions to one blueprint line from the facts it tests. Topics inside a line are sized by these questions, which is why one topic (SCFE, for example) can appear under more than one line.

Tested facts and "Tested N×"

Each fact is a statement SnapOrtho extracted from question explanations. Facts that several questions tested are grouped, and "Tested 4× · 2009–2023" means four practice questions written in those years hinged on it. Core facts are the most repeated in their topic.

Free, with an account for the facts

The whole map is open to everyone. The ranked facts need a free SnapOrtho account, which also keeps your weak-area marks in sync across devices.
