The most common injuries
to the joint are the result of wrenching and twisting forces or a traumatic
blow to the joint. These usually involve only the soft tissues of
the joint -- the ligaments, tendons, muscles, and the cartilage or menisci.
The types of injuries that may result include a sprain, in which the tissues
are "pulled" beyond their normal elastic limits, or a tear or rupture,
usually caused by a twisting force. There may be a partial or complete
tear of the structure and in some cases, an accompanying fracture or splintering
of bone tissue at the site of bone and soft-tissue connection.
Sprained ligaments are among
the most common injuries. The signs and symptoms of a sprained or torn
ligament include a sensation of a "pop" within the joint upon impact, a
lack of joint stability, pain, swelling, and reduced mobility of the joint.
Similar symptoms are experienced when there is a tear or rupture of a tendon
or cartilage, and the joint may produce a "clicking" sound during movement.
In some cases, the joint "locks," and mobility of the joint is reduced.
Minor injuries to the soft tissues of the joint may respond well to first
aid, using the “RICE” formula. If symptoms
persist for more than one or two weeks, a physician should be consulted. |
