The intraoperative finding you didn't plan for defines the outcome — and the decision it demands cannot wait. Apply fixation without the decision framework behind it and the result is a subtalar fusion in varus, a TAA tibial cut off the mechanical axis, or a calcaneal ORIF closed before the posterior facet was confirmed. This handbook delivers 75 Operative Crossroads frameworks embedded across 25 chapters — each naming the intraoperative trigger that changes the plan and the findings that must be confirmed before closure. • The 42% rule, enforced — the fluoroscopic quality gate preventing the 1mm lateral talar shift after ankle fracture ORIF that produces the irreversible arthrosis that follows it. • Before you close the calcaneal ORIF — the wrinkle sign timing, the four-step reduction sequence, and the three-view Broden composite that must pass simultaneously before the first locking screw is seated. • The talar neck malunion that never happens — bilateral cortical visualization before any K-wire, because fluoroscopy alone cannot catch the varus malreduction that accelerates subtalar arthrosis. • Charcot reconstruction that holds — the four superconstruct principles and an extended TTC nail anchored in normal tibial diaphysis above the disease zone. • Diabetic limb salvage with a confirmed endpoint — the paprika sign as the intraoperative standard for osteomyelitis margins, and the 2:1 TMA plantar flap ratio that prevents the stump breakdown that ends independence. • The FHL transfer at maximum length — harvest at the master knot of Henry, not the sustentaculum, for the tendon length that calcaneal tunnel routing requires. Written for orthopaedic surgery residents, foot and ankle fellows, and advanced practice providers who need operative decision architecture as much as operative technique. Add this book to your pre-case preparation tonight and every patient on tomorrow's list gets a surgeon who knows not just the steps, but the decisions.
