Why Does My Hip Hurt?
As People Age, So Do Their Bones
Many times individuals develop certain conditions that cause their hips
to hurt. Listed below are some common causes for discomfort in the
hip joint region.
Osteoarthritis
Non-inflammatory degenerative disease of the joint is characterized by
degeneration of cartilage. The joints in our body are covered with
a protective layer of cartilage, which acts as a natural shock absorber
or cushion. Over time, this natural cushion may wear due to
osteoarthritis; a disease causing the progressive deterioration of joint
cartilage. If the wear becomes significant, it can result in the
painful condition of bone rubbing on bone.
Osteonecrosis
Literally, osteonecrosis or avascular necrosis means death of bone.
It occurs when an area of bone loses its blood supply. Without
blood, bones will break down and collapse. Osteonecrosis of the
hip joint accounts for more than 90 percent of all osteonecrosis cases.
Each year, between 10,000 to 20,000 people develop osteonecrosis in the
US. This disease is primarily seen in people 20 to 40 years old,
with men being more susceptible.
Rheumatoid Arthritis
This condition occurs when the body's own immune system attacks the
synovial lining of the joints, just as it would foreign bacteria.
Synovial fluid is a clear, smooth oil-like lubricating liquid that makes
it easier for the joints to move.

Traumatic Arthritis
Traumatic arthritis results when the joint or the ligaments surrounding
it are damaged by fracture, dislocation, or accident-related injury.
All arthritic conditions result in stiffness, swelling, and the loss of
motion. It becomes difficult to put pressure on the hip, and the
joint becomes increasingly tender and swollen. As time passes,
arthritis of the hip can significantly affect the ability to walk.
