Micro-computed tomography (µCT) is a non-destructive imaging tool that is instrumental in assessing bone structure in preclinical studies, however there is a lack of consensus on µCT procedures for analyzing the bone healing callus. This study provides a step-by-step µCT protocol that allows the monitoring of fracture healing.

FAQs
The sequence of inflammation and hematoma formation, soft callus development, hard callus development, and prolonged remodeling provides a framework for judging progression after injury or surgical repair. Each stage reflects a different level of structural recovery. Comparing observed findings with this sequence helps clinicians decide whether repair appears to be advancing normally or requires closer evaluation.
Remodeling is a prolonged phase that follows callus development and contributes to the restoration of bone structure and function. Its extended course means that apparent repair is not necessarily the endpoint of recovery. Including remodeling in the analysis allows clinicians and investigators to evaluate skeletal healing beyond the initial formation of a hard callus.
Bone Healing Analysis is used to identify delayed union or nonunion when recovery does not progress as expected. These findings are clinically important because they can change how the fracture or surgical repair is managed. The analysis connects evidence from physical examination and imaging with decisions about whether continued observation or treatment adjustment is appropriate.
Physical examination and imaging provide complementary evidence about recovery after fracture or surgical repair. Examination contributes clinical information, while imaging evaluates changes in the repaired bone and surrounding healing process. Considering both sources rather than relying on a single assessment supports a more systematic judgment of progression, abnormal healing, and restored function.
A basic workflow follows the healing course from the initial injury or surgical repair through callus formation and remodeling. Clinicians assess the patient physically, review imaging for structural changes, and interpret the findings against the expected stages of repair. The resulting assessment helps determine whether healing is normal or whether delayed union or nonunion should be considered.
In medical research, this analysis helps evaluate fracture fixation, bone grafts, biomaterials, and therapies intended to improve skeletal repair. Investigators can use the healing stages, examination findings, and imaging changes to judge how an intervention affects structural recovery and patient outcomes. It therefore connects experimental treatment design with clinically meaningful evaluation of bone repair.
