Study Notes
Hematoma Formation
- A hematoma, or mass of clotted blood, forms at the site of the fracture.
- The injured area becomes swollen, painful, and inflamed due to the response of dead bone cells.
- This stage lasts several weeks.
Fibrocartilaginous Callus Formation
- A fibrocartilaginous callus forms, consisting of collagen fibers and cartilage, bridging the broken ends of the bone.
- This healing stage typically lasts up to three weeks.
Bony Callus Formation
- The fibrocartilaginous callus is gradually replaced by spongy bone, leading to the formation of a bony callus.
- This stage can last approximately 3 to 4 months.
Bone Remodeling
- In this stage, remaining bone fragments are reabsorbed, and compact bone replaces spongy bone around the periphery.
- The duration for this process can range from weeks to months, varying based on the severity of the fracture.
