摘要

Fracture healing is a complex process driven by endogenous regenerative mechanisms, with early biological responses playing a pivotal role in determining healing outcomes. During this critical phase, the body establishes a dynamic equilibrium across multiple systems, akin to the precise calibration of a biological clock. The inflammatory response is tightly regulated through the interplay of pro- and anti-inflammatory signals, ensuring efficient immune cell recruitment for necrotic tissue clearance while preventing excessive inflammation that could compromise surrounding tissues. Simultaneously, the coagulation cascade maintains a delicate balance between clot formation and anticoagulation, facilitating hemostasis and repair initiation while mitigating thrombotic risks. Energy metabolism is similarly fine-tuned, with coordinated anabolic and catabolic activity providing the necessary substrates and energy for regeneration. These interconnected processes collectively drive the phenotypic transformation of cells from diverse lineages, ultimately shaping the trajectory of fracture healing. In this review article, we propose an integrated ‘biological orchestration’ framework. Rather than viewing these systems in isolation, we discuss the intricate crosstalk among inflammatory homeostasis, coagulation balance, and metabolic adaptation. Additionally, we provide a multi-dimensional exploration of the fracture healing process, encompassing the microenvironment, intra-osseous dynamics, and the regulatory influence of surrounding tissues. By elucidating the temporal orchestration of these systems, this review offers theoretical insights that may inform the development of precise therapeutic strategies for bone regeneration.
