Final answer:
Degenerative changes in a joint are typically the result of mechanical stress, aging, arthritis, and conditions like bursitis and bacterial infections. However, immobilization of the joint does not typically result in joint degeneration and instead, maintaining joint movement is necessary for joint health. The correct option are A) and B).
Step-by-step explanation:
Degenerative changes in a joint can result from a variety of factors, including mechanical stress, inflammation, aging, and arthritis. These can cause the erosion and loss of articular cartilage that covers the bone surfaces at synovial joints, leading to inflammation, pain, and joint stiffness.
Such degeneration can be exacerbated by certain risk factors such as injury, physical labor, excessive weight, and participation in sports that stress the joints. Bursitis, an inflammation of the bursa that can be triggered by infection among other causes, and bacterial infections that affect the joints directly can also lead to degradation of joint tissues.
However, continual immobilization is typically not associated with degenerative changes, as movement is necessary to maintain joint health and prevent stiffness and muscle weakness.
Thus, immobilization of the joint would be the correct answer as it is the option that is least likely to lead to degenerative joint changes. Option A) and B) are the correct one.
