Fracture repair involves four steps: fracture hematoma, fibrocartilaginous callus, bony callus, and bone remodeling.

Calcitonin is released by the thyroid gland to decrease blood calcium levels.

Parathyroid hormone (PTH) stimulates osteoblast cell activity.

PTH stimulates calcium absorption from the gut.

Blood calcium levels are maintained by the opposing effects of calcitonin and PTH.

Osteoclasts are responsible for increasing blood calcium levels.

Hypercalcemia is characterized by blood calcium levels below 9mg/100ml blood.
