2,4,5
Rationale 1: A cartilage collar does form, but not in the remodeling phase.
Rationale 2: The remodeling process is directed by mechanical stress and weight bearing, causing the bone to become stronger in relation to its function.
Rationale 3: Granulation is involved in the formation of a connective bridge, but this does not occur in the remodeling phase.
Rationale 4: The remodeling process involves resorption of the excess callus in the marrow space and the external aspect of the fracture.
Rationale 5: The remodeling process involves resorption of the excess callus in the marrow space and the external aspect of the fracture. The process is directed by mechanical stress and weight bearing, causing the bone to become stronger in relation to its function.
