- Osteoporosis
Thinning of the bones, with reduction in bone mass, due to depletion of calcium and bone protein. Osteoporosis predisposes a person to fractures, which are often slow to heal and heal poorly.

- Osteosynthesis
A surgical procedure that stabilizes and joins the ends of fractured (broken) bones by mechanical devices such as metal plates, pins, rods, wires or screws. Osteosynthesis refers particularly to internal fixation of a fracture by such means, as opposed to external fixation of a fracture by a splint or cast.
