ANATOMY

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: -There are three stages of bone healing: the inflammatory, reparative, and remodeling stages.

Detailed explanation-3: -The remodelling cycle occurs within the basic multicellular unit and comprises five co-ordinated steps; activation, resorption, reversal, formation and termination. These steps occur simultaneously but asynchronously at multiple different locations within the skeleton.

Detailed explanation-4: -Stages are hematoma, inflammation, proliferation, callus, remodel. 5. Complications include non-union, malunion, & delayed union.

Detailed explanation-5: -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
