Hip Replacement and Resurfacing

Hip Replacement Surgery Idaho

This information is designed to help you  understand the benefits and limitations of total hip replacement. If your hip has been sustained damage from arthritis, a fracture, or other conditions, a hip replacement might be right for you. Hip replacements are most commonly performed for individuals for whom common activities such as walking or getting in and out of a chair may be painful and difficult. People suffering with chronic hip pain often struggle to do everyday tasks like putting on their shoes and socks and may even be in pain while sitting down or lying in bed.

If medications, changes in your everyday activities, and the use of walking supports do not significantly improve your symptoms, it may be time to  consider hip replacement surgery. Hip replacement surgery is a safe and effective and  can make significant improvements in pain, increase motion, and help you get back to enjoying normal, everyday activities.

Hip Anatomy

Hip Replacement IdahoThe hip is one of the body’s largest joints, and is what doctors refer to as a “ball-and-socket” joint. The socket of this joint is formed by the acetabulum, which is part of the large pelvis bone. The ball is the femoral head, which is the upper end of the femur (thighbone).

Both the surface of the hip socket and the head of our thighbone is covered in cartilage, a smooth tissue that cushions the ends of the bones and enables them to move easily.

A thin tissue called synovial membrane surrounds the hip joint. In a healthy hip, this membrane makes a small amount of fluid that lubricates the cartilage and eliminates almost all friction during hip movement.

Bands of tissue called ligaments (the hip capsule) connect the ball to the socket and provide stability to the joint.

Common Causes of Hip Pain

Hip pain is most commonly caused by arthritis, with osteoarthritis, rheumatoid arthritis, and traumatic arthritis being the most common forms.

  • Osteoarthritis is typically age-related and is commonly referred to as”wear and tear” arthritis. It most commonly occurs in people 50 and older, or in individuals with a genetic predisposition to arthritis. As cartilage cushioning the bones of the hip wears away, the bones  rub against each other, which causes hip pain and stiffness. Osteoarthritis may also be caused or exacerbated by subtle irregularities or defects in the hip as it developed during childhood.
  • Rheumatoid arthritis is an autoimmune disease characterized by the inflammation and thickening of the synovial membrane. Chronic inflammation damages the cartilage, which leads to pain and stiffness. Rheumatoid arthritis is the most common kind of “inflammatory arthritis.”
  • Post-traumatic arthritis generally follows a serious hip injury or fracture. Cartilage in the hip can be damaged during a severe injury, which sometimes leads to prolonged hip pain and stiffness over time.

Hip Resurfacing

A newer technique for hip replacement that has recently emerged is called hip resurfacing. In this procedure, the socket is replaced similar to a total hip replacement. The femur, however, is covered or “resurfaced” with a hemispherical component. This fits over the head of the femur and spares the bone of the femoral head and the femoral neck. It is fixed to the femur with cement around the femoral head and has a short stem that passes into the femoral neck.
