Bone fractures heal through a well-established, multi-phase biological timeframe consisting of inflammation, proliferation, and remodeling stages. Multiple clinical and experimental studies confirm the predictability of this physiological timeline.
The claim states that broken bones require a predictable biological timeframe to heal. The retrieved literature unanimously discusses bone fracture healing as progressing through distinct, canonical phases (inflammation, soft callus, hard callus, remodeling), supporting the predictability of the healing timeline. No papers contradict this timeline. Therefore, the verdict is SUPPORTED.
