Abstract
Abstract Bone bleeding and bone defects arising from trauma or bone tumor resection pose a great threat to patients and they are challenging problems to orthopedic surgeons. Traditional hemostatic materials are not suitable for bone fractures where compression cannot be applied, neither are they effective during surgeries where large amounts of body fluids prevent them from adhering to the large and irregular bone wound sites. This research introduces a catechol‐conjugated chitosan (CHI‐C) multi‐functional hydrogel with adhesion, self‐healing, cytocompatibility, hemocompatibility, and blood cell coagulation capacity. The hydrogel can be injected into internal and irregular bleeding sites and bone defective areas, and then rapidly self‐heals (within 2 min) to an integrated hydrogel that fully fills the defective sites and strongly sticks to bleeding areas in the presence of body fluids during surgery. In vivo experiments using a rabbit ilium bone defect model demonstrate quick hemostasis after the hydrogel is applied and the blood loss is only ¼ compared to the untreated injuries. In addition, the bone regeneration is not interfered by the hydrogel and the bone defect is no longer visible with disappearance of the hydrogel after 4 weeks. This multi‐functional hydrogel is potentially valuable for clinical applications towards tissue adhesion, hemostasis, and bone regeneration.

Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
