Detailed explanation-1: -There are four stages in the repair of a broken bone: 1) the formation of hematoma at the break, 2) the formation of a fibrocartilaginous callus, 3) the formation of a bony callus, and 4) remodeling and addition of compact bone.
Detailed explanation-2: -Fractures heal by forming callus, which follows three overlapping phases: inflammatory, reparative and remodelling.
Detailed explanation-3: -Answer and Explanation: The proper sequence of events in bone repair is: hematoma formation, callus formation, callus ossification and remodeling of bone.
Detailed explanation-4: -Hematoma Formation (Days 1 to 5) Fibrocartilaginous Callus Formation (Days 5 to 11) Bony Callus Formation (Days 11 to 28) Bone Remodelling (Day 18 onwards, lasting months to years) 08-May-2022
Detailed explanation-5: -Hematoma Formation.-a mass of clotted blood (hematoma) forms at the fractured site. Fibrocartilaginous Callus Formation.-a fibrocartilagenous callus consists of a mass collagen fibers and cartilage that bridge the broken end of the bone. Bony Callus Formation. Bone Remodeling.
