Why might a person suffering from osteoporosis benefit from increased calcium ingestion?

In osteoporosis, a decrease in the calcium content of bones leads to bones that are weak and brittle. Increased calcium ingestion raises blood calcium levels and triggers osteoblasts to form new bone. This new formation of bone can help diminish the bone decrease due to overactive osteoclasts.

Mary has just finished pitching a fast-pitch softball game. What joint is most likely to be sore, and why?

Pitching a softball repeatedly requires the shoulder's ball-and-socket joint to sustain a great deal of circumductive forces. The shoulder is most likely to be sore as a result of these repeated forced circumductions and the friction and tension associated with them.

When playing a contact sport, which injury would one expect to occur more frequently: a dislocated shoulder or a dislocated hip? Why?

Shoulder dislocations would occur more frequently than hip dislocations because the shoulder is a more mobile joint. Because of its mobility, the shoulder joint is not bound tightly by ligaments or other structures and is, therefore, easier to dislocate when excessive forces are applied. The hip joint, although mobile, is stabilized by four heavy ligaments; bones fit together snugly in the joint. The synovial capsule of the hip joint is larger than the shoulder, and the range of motion is not as great. These factors contribute to the joint being more stable and less easily dislocated.

Jennifer undergoes a pelvic scan to determine if she sustained any fractures as a result of a car accident. To her surprise, the technician does not find any fractures. He does note, however, that Jennifer's acetabulae are markedly shallow bilaterally. What might the technician conclude about Jennifer's pelvic bone structure, as a result of this finding?

The technician should explain to Jennifer that she may have rather flexible hip joints. As the head of the femur fits into the acetabulum of the coxal bone, the ligament of the femoral head and the bones of the acetabulum limit the movements of the femur in such an articulation. Since Jennifer's acetabulae are shallow, this limiting factor would be reduced. Thus, the increased flexibility may have prevented any fractures during the accident.
