Computer navigation and computer assisted surgeries

The skills of the surgeon are increased by computer assisted surgeries. This is also called computer navigation and mostly used in knee replacement or hip replacement surgeries. The computer is used a tool to navigate through the troubles area and to validate the exact location of the problem. Removal of damaged surfaces of the bone requires guidance to locate and pin point the location. The system also helps in deciding the size of the implant and later during surgery helps to position the implant at its correct location.


  • Since exact location and position is known with computer navigation smaller incisions are sufficient to complete the surgery successfully. This not only reduces the time of surgery but also helps in speed recovery of the patient.
  • This also helps in reducing bleeding and the rates of transfusion.
  • Damage to the tissues are minimised.
  • Risk of emboli is reduced.
  • Helps in attaining a perfect alignment of the bones and joints that ensures a longer life for the implants.
  • Dislocation problem is reduced to a greater extent.

Total Hip replacement:

The success of total hip replacement rests on placing the acetabular and femoral parts. Hip navigation powered by a computer aided program helps provides a real time views of the implants and the positions of the other components that help the surgeon to proceed with the surgery with precision and accuracy. A perfect alignment is also achieved as the surgeon is guided by an assured view of what that is happening and what that is being done.

Partial hip Replacement:

By using the computer aided technic femoral bone indentation is avoided. It also helps in achieving the accurate positioning of the femoral hip. The other advantages include retention of bones that would be useful for future revisions, reduction of stress and reduction in future dislocations. Obtaining the success in the first attempt becomes a possibility in this case.
