Total HIP Replacement with Navigation

Total HIP Replacement:

A hip that is painful as a result of osteoarthritis (OA) can severely affect your ability to lead a full, active life. HIP replacement surgery (also called hip arthroplasty) is the ultimate solution for advanced hip OA. The prosthesis is made of two main parts.

  • Acetabular component (socket)

The acetabular component is made of a metal shell with a plastic inner liner that provides the bearing surface. The plastic used is so tough and slick.

  • Femoral component (stem and ball)

The femoral component replaces the femoral head. The femoral component is made of metal. Sometimes, the metal stem is attached to a ceramic ball.

The surgeon begins by making an incision on the side of the thigh to allow access to the hip joint. Once the hip joint is entered, the surgeon dislocates the femoral head from the acetabulum. Then the femoral head is removed by cutting through the femoral neck with a power saw.

Attention is then turned towards the socket. The surgeon uses a power drill and a special reamer (a cutting tool used to enlarge or shape a hole) to remove cartilage from inside the acetabulum. The surgeon shapes the socket into the form of a half-sphere. This is done to make sure the metal shell of the acetabular component will fit perfectly inside. After shaping the acetabulum, the surgeon tests the new component to make sure it fits just right.

HIP Navigation:

HIP Navigation provide surgeons the data they need for cup and stem positioning, leg length determination, correct femoral offset and real time intra-operative assessment of stability and range of motion. It helps the surgeon align and orient the hip implant with more precision than ever before. The surgeon is able to view an interactive display of the lines, angles, and measurements needed to position your hip implant. This combination of computers with wireless cameras and infrared technology is significantly improving medical technology for orthopaedic surgery.

 How does computer navigation work?

  • In the operating room infrared optics and tracking software continually monitor the position and mechanical alignment of the joint replacement components relative to your specific anatomy.
  • Minimally invasive smart wireless instruments send data about to the joint movements (kinematics) to a computer.
  • The computer analyzes and displays the kinematic data on the screen in the form of charts and graphs.
  • These images provide your surgeon with the angles, lines, and measurement needed to best align your hip or knee implant.


What are the potential benefits?

  • It allows your surgeon to make adjustments to within a fraction of a degree, helping to ensure optimal “fit” for your joint.
  • It provides your surgeon with a comprehensive view of your joint mechanics.
  • It helps your surgeon correctly position your joint in situations where it is otherwise difficult to get a good view of your anatomy.
  •  It may lead to improved stability for your joint and optimal range of motion for you.

MIS Hip Replacement:

  • Minimally invasive surgery (MIS) is a general term used to describe a surgical procedure that utilizes a smaller incision(s) than conventional surgery. In some MIS procedures the amount of soft tissue (muscles and tendons, etc.) that are disrupted during surgery may also be reduced.
  • The potential benefits may be a smaller scar because of the reduced incision and the potential for a faster recovery because of less tissue disruption as well as the potential for less blood loss.
  • The potential risks are the results that may be varied from patient to patient. Not all patients may realize the potential benefits from these relatively new procedures. Also, the risks, which are normally encountered in conventional hip joint replacement, still remain.


  • The lifespan of the prosthesis

Two major factors affecting the lifespan of the prosthesis are quality of the prosthesis and experience of the surgeon.

  • Loosening

Cause of this complication is mostly found in 6 weeks after the operation. The main of cause comes from 2 factors.

  • How to patient follow physician suggestion after the operation.
  • How to surgeon correctly position your joint.


  • Length of Leg

During surgery, surgeon has to check the length of legs which must be equal this depends on the surgeon’s expertise.

Not recommended for these conditions:

  •  Young, active patient
  • Fat patient. Physician will suggest to loss your weight before operation.
  • Patient who has cardiac, lung, kidney problem or risk to get an infection.
