Total Hip Replacement

If chronic hip pain and reduced mobility persist despite conventional treatments, hip replacement surgery, a minimally invasive procedure, may offer the relief you seek!

Overview

Hip Replacement Surgery

Are you suffering from a painful joint condition as a result of arthritis of the knee to a fracture of the hip?

Yanhee International Hospital delivers exceptional orthopedic solutions to get rid of pain and reestablish ease of movement.

The treatments we offer vary from non-surgical to complex reconstructive surgeries using advanced techniques.

The ultimate measure of our success is our patient’s ability to return to activities that they love and their enduring joint health, possibly thirty years after getting a replacement knee or hip.

When is hip replacement surgery necessary?

Hip replacement surgery becomes necessary for individuals with hip joint problems that cause pain and interfere with normal movements, despite treatment efforts. Osteoarthritis is the most common reason for such issues, although conditions like rheumatoid arthritis, osteonecrosis, and hip injuries, fractures, or tumors can also lead to hip joint breakdown, necessitating hip replacement surgery.

In the past, hip replacement surgery was primarily reserved for individuals over 60 years old, as it was believed that they would put less stress on the artificial hip due to lower activity levels compared to younger individuals. However, advancements in technology have improved the durability of artificial hip components, making hip replacement surgery viable for younger people. Today, an individual’s overall health and activity level are more crucial than age in predicting the success of hip replacement surgery.

Certain factors, such as chronic conditions like Parkinson’s disease or muscle weakness, can increase the risk of injury or dislocation of an artificial hip and may make some individuals unsuitable candidates for the surgery. Similarly, individuals at high risk for infections or in poor health may have a lower likelihood of successful recovery and may not be good candidates for hip replacement surgery.

Recent studies suggest that individuals who opt for surgery before significant joint deterioration occurs tend to have quicker recoveries and better outcomes.

How is hip replacement surgery performed?

The hip joint is situated where the upper end of the femur (thigh bone) meets the pelvis (hip bone). A ball at the end of the femur, called the femoral head, corresponds to a socket (acetabulum) in the pelvis to enable a wide range of motion. Please refer to the figure below.

At some point in a traditional hip replacement, which can last from 1-2 hours, the surgeon creates a 6-to-8-inch incision over the side of the hip through the muscles and removes diseased bone tissue and cartilage from the hip joint, and at the same time keeping the healthy parts of the joint untouched. Next, the surgeon replaces the head of the femur and acetabulum with new, artificial parts.

The brand-new hip is constructed of materials that permit a natural gliding motion of the joint.

Over the last 10 years, several surgeons started doing what is called a minimally invasive, or mini-incision, hip replacement, which needs smaller incisions and shorter recovery time than traditional surgery. Prospects for this kind of surgery are generally age 50 or younger, of normal weight based on body mass index and healthier compared to prospects for traditional surgery.

Whether you get traditional or minimally invasive surgery, the parts used to replace the joint are the same and appear in two general types, cemented and uncemented.

Cemented parts are attached to the available healthy bone with unique glue or cement. Hip replacement making use of these parts is called a cemented procedure.

Uncemented parts make use of a process called biologic fixation, which supports them in place. This indicates that the parts are designed with a porous surface that permits your own bone to grow into the pores and hold the parts in place. At certain times a surgeon uses a cemented femur part and uncemented acetabular part. This combination is called a hybrid replacement.

In a total hip replacement (hip arthroplasty), the defective bone and cartilage are taken out and replaced with prosthetic components.

  • The defective femoral head is removed and replaced with a metal stem that is positioned into the hollow center of the femur. The femoral stem may be either cemented or “press fit” into the bone.
  • A metal or ceramic ball is placed on the top part of the stem. This ball replaces the defective femoral head that was removed.
  • The defective cartilage surface of the acetabulum (socket) is removed and replaced with a metal socket. Screws or cement may be used to secure the socket in place.
  • A plastic, ceramic, or metal spacer is positioned between the new ball and the socket to allow a smooth gliding surface.

The most frequent source of chronic hip pain and disability is arthritis. Osteoarthritis, rheumatoid arthritis, and traumatic arthritis are the best-known kinds of this disease.

  • Osteoarthritis is an age-related “wear and tear” form of arthritis. It is generally set in people 50 years of age and older and usually in people who have a family history of arthritis. The cartilage padding the bones of the hip wears away. The bones then rub against one another, resulting in hip pain and stiffness. Osteoarthritis may also be brought about by slight abnormalities in how the hip developed in childhood.
  • Rheumatoid arthritis is an autoimmune disease where the synovial membrane gets irritated and inflamed and eventually thickens. This longstanding inflammation will damage cartilage, producing pain and stiffness. Rheumatoid arthritis is the most prevalent type of a group of conditions called inflammatory arthritis.
  • Post-traumatic arthritis results from a severe hip injury or fracture. The cartilage can be damaged and causes hip pain and stiffness with time.
  • Avascular necrosis. When the blood supply to the femoral head is compromised, the surface of the bone may collapse, and arthritis results. Injuries to the hip, like a dislocation or fracture, disrupt the blood supply to the joint. Certain diseases may also induce avascular necrosis.

Childhood hip disease. Some infants and children have hip problems. Even if the problems are taken care of, they may still trigger arthritis later in life. This occurs because the hip may not develop normally and the joint surfaces are affected.

Adjustments with Your New Hip

After hip replacement surgery, you may experience some numbness in the skin around the incision and stiffness, particularly when bending excessively. However, these issues typically improve over time, and most patients find them minor compared to the pain and restricted functionality they experienced before the surgery.

It’s important to note that your new hip may activate metal detectors used for security in airports and some buildings. If the alarm is triggered, inform the security agent about your hip replacement. You can also request a card from your surgeon confirming that you have an artificial hip.

Protecting Your New Hip

To ensure the longevity of your hip replacement and maintain its functionality, consider the following precautions:

Engage in Gentle Exercise: Participate in a light exercise regimen to maintain strength and mobility in your new hip.

Prevent Falls: Take precautions to avoid falls and injuries, as a broken bone in your leg may require additional surgery.

Regular Check-ups: Schedule regular follow-up exams and x-rays with your surgeon, even if your replacement seems to be functioning well, to monitor its condition and address any potential issues early on.
