Narrative historical review tracing femoral intramedullary nailing from Küntscher's foundational principles through four generations of implant design and surgical technique, explaining why North American adoption was delayed until the late 1970s and what technological and biological forces drove each subsequent generation.
When selecting nail configuration for a femoral shaft fracture, recognize that static locking with a closed-section nail was the construct that eliminated the malunion epidemic of early interlocking nailing — dynamic mode should not default based on feel alone.
When managing metaphyseal femur fractures where a nail won't achieve translational stability, think Poller (blocking) screws to redirect the nail and restore angular and translational control.
