The following are some of the most common hip problems:
Arthritis. The most common cause of the
breakdown of hip tissue. There are three kinds of arthritis that
commonly affect the hip, including the following:
Osteoarthritis. Also referred to as "wear
and tear" arthritis; this type of arthritis involves the cartilage that
cushions the bones of the hip wearing away, letting the bones then rub
together, causing hip pain and stiffness.
Rheumatoid arthritis. A disease in which,
for unknown reasons, the synovial membrane becomes irritated and
produces too much fluid. It damages the cartilage, leading to pain and
Traumatic arthritis. Often the result of an
injury or fracture, there are more than 300,000 hospitalizations for
hip fractures in the United States every year.
Avascular necrosis. Involves the loss of bone
caused by insufficient blood supply, injury, and bone tumors and may
lead to breakdown of the hip joint.
Bursitis. In this condition, the bursa, a
closed fluid-filled sac that functions as a gliding surface to reduce
friction between tissues of the body, becomes inflamed. There are two
major bursae of the hip, both of which can be associated with stiffness
and pain around the hip joint, including the following:
Hip pointer. A bruise or tear in the muscle
that connects to the top of the ilium (the crest of the pelvis, just
below the waist). Causes of a hip pointer may include a blow, a fall, or
a quick twist or turn of the body.
