Question

which of the following is the correct sequence of events in the healing of a bone fracture? multiple choice bone remodeling → soft callus formation → hard callus formation → hematoma formation bone remodeling → hard callus formation → soft callus formation → hematoma formation hematoma formation → soft callus formation → hard callus formation → bone remodeling hematoma formation → hard callus formation → soft callus formation → bone remodeling soft callus formation → hard callus formation → hematoma formation → bone remodeling

Explanation:

When a bone fractures, blood vessels break and a hematoma forms first. Then, a soft callus made of fibrocartilage is formed. This is replaced by a hard callus of bony tissue. Finally, bone - remodeling occurs to restore the bone to its original shape.

Answer:

C. Hematoma formation → soft callus formation → hard callus formation → bone remodeling
