ABOS Part II framing
Case-list oral defence, not a generic viva clone
ABOS public materials describe Part II around selected candidate cases, examiner questioning, and defence of real clinical decisions. Our case-list orals rehearse data gathering, diagnosis and interpretation, treatment planning, technical decision-making, outcomes, and applied orthopaedic knowledge — an independent study aid, not an official ABOS scoring simulator.
