Hip Replacement Surgery
The hip joint is commonly called a "ball and socket" joint. The
"ball" of the hip joint, the femoral head, rests within a "socket"
called the acetabulum (see figure below). The femoral head and acetabulum
are covered by a specialized surface, articular cartilage, which allows
smooth and painless motion of the joint. With hip injury or disease, articular
cartilage undergoes degeneration and wears away. The joint surfaces become
rough and irregular resulting in pain and stiffness. This is commonly known
as "arthritis" but it has many causes. The onset of pain is gradual
and, initially, it occurs only after higher levels of physical activity.
Pain gradually increases and may become present at rest as well. Physical
disability includes a limp, muscle spasm, and decreased range of motion
with increasing stiffness.
Treatment options include reducing stress on the hip, physical therapy,
and medications. Weight reduction is highly desirable, since one pound weight
loss equals three pounds in stress reduction on the hip while walking! The
use of a cane or walking stick is also a very effective means of reducing
stress on the hip. Physical therapy and exercises are directed at preserving
muscle strength and range of motion within the limits of pain. Recommended
medications include anti-inflammatory agents such as aspirin, Indocin, Motrin,
Feldene, Naprosyn, Voltaren, Lodine, and others.
Selection of the optimal treatment plan should be consistent with the degree
of pain, the amount of hip disability, and the nonsurgical and surgical
alternatives. The individual's anticipated life span will also influence
the selection of treatment.
