Philosophy of the X-ray
When to order films, how to trust them, and the system you use every time.

At a glance
Almost every orthopedic decision starts with a film. Pain in a joint, swelling, a possible septic joint — order the series. You have the exam and the story; that is the advantage over a radiology read you have not looked at yourself.
Use a system every time. You own incidental findings on the study you ordered. One view is never enough.
Technique pointers
Before you call it normal
- Confirm name, laterality, date — labels are wrong more often than you want
- Orthogonal views (AP and lateral). Repeat after a failed reduction attempt
- Order plain films even when a CT exists — a flat plate shows the whole ring or shaft at once
Reading order 1. Obvious injury on each view 2. Then proximal-to-distal cortices, joints, canals 3. Soft tissue last, same direction 4. Compare to the other side when it exists
Decision-making
Consults without films make everyone slower. A CT gantry can close an open-book pelvis that a flat-plate AP would have shown. If the exam and the labeled image disagree, trust the exam and get more pictures — not a confident wrong side.
High-yield / exam
- Orthogonal views before you decide
- Never skip looking at the images yourself
- Repeat films after someone else's reduction attempt
- Systematic second pass after the obvious fracture
