Western Orthopaedics

Computer-assisted Robotic Surgery

Across Western Orthopedics’ six clinics, orthopedic surgeon and specialist Dr Pavitar Sunner implements the latest in premier technology when performing Computer-assisted Robotic Surgery. Dr Sunner is able to greatly improve his patient’s surgical outcomes by utilising these advanced methods of surgical execution.


What is Computer-assisted Robotic Surgery?

The process allows a surgeon to simultaneously visualise two or three-dimensional views of a patient’s anatomy on a monitor. This type of surgery provides real-time, intra-operative views of surgical instruments whilst also showing the relative digital positioning of implantable devices.


How Does it Work?

Infrared sensors are fixed to the bone and surgical instruments. These sensors provide 3D data, which is generated into real-time images with the help of appropriate computer software. With assistance from 3D imagery, a surgeon is then able to resurface and cut the bone where needed whilst simultaneously fixing an implant precisely & accurately according to the pre-operative surgical plan.

Surgeons who use the robotic system find that for many procedures it enhances precision, flexibility and control during the operation and allows them to better see the site, compared with traditional techniques. Using robotic surgery, surgeons can perform delicate and complex procedures that may have been difficult or impossible using other methods. Often, robotic surgery makes minimally invasive surgery possible.

The benefits of minimally invasive surgery include:

• Fewer complications, such as surgical site infection

• Less pain and blood loss

• Quicker recovery

• Smaller, less noticeable scars

When is it Performed?

It is not always an option for everyone. It is important to talk with your doctor about the benefits and risks of robotic surgery and how it compares with other techniques, such as other types of minimally invasive surgery and conventional open surgery.
