Final answer:
The correct sequence of bone repair is Inflammation, Repair, Remodeling, starting with an inflammatory response, followed by the formation of calli, the replacement of this cartilage by trabecular bone, and finishing with remodeling of the healed bone.
Step-by-step explanation:
The proper sequence of events in bone repair is Inflammation, Repair, Remodeling. When a bone fracture occurs, initially the body responds with an inflammation process, where the area becomes red, warm, swells, and feels painful due to chemical signals that lead to vasodilation and fluid leakage. Following this, the repair phase begins, involving blood clotting and regeneration of tissue as fibroblasts deposit collagen to form a soft callus which eventually transforms into a hard callus made from trabecular bone. Finally, the bone undergoes remodeling, a process during which the new bone is gradually shaped into its normal form and the excess material from the callus is removed, allowing the bone to adapt to stress and become stronger.
Specifically, these events in bone healing are orderly, with each phase setting the stage for the next. A fracture hematoma forms first (inflammation), followed by the creation of internal and external calli (repair), after which cartilage of the calli is replaced by trabecular bone (repair continues), and finally, the bone remodeling occurs to finalize the structure of the healed area.
