Computer assisted surgery is a revolutionary medical technology which offers surgeons the proficiency to operate with advanced visualization resulting in better outcomes in surgical procedures. Computer assisted surgery is often referred to as the surgical navigation owing to the fact that it works much alike GPS navigation system used in an automobiles and thus enables the surgeon to trace the location of the surgical instruments and implants relative to the anatomy of the patient’s body in real time. Surgical navigation is the leading edge medial technology that was first introduced and implemented for the neurosurgical procedures wherein every millimetre matters and surgical precision stands extremely important, but now it is being used in orthopaedics, spine, ENT, and trauma surgeries as well. Computer navigation technology is currently being practiced extensively by the best orthopaedic surgeons for knee replacement and hip replacement surgeries for best results. Hip replacement surgery, also called total hip arthroplasty, entails replacing diseased hip joint with a man made biocompatible artificial joint, called prosthesis, made of metal or ceramic to help the patient suffering from hip pain and instability caused by degenerative joint disease like osteoarthritis and other conditions like hip joint deformity, avascular necrosis, traumatic or sports injury, Paget’s disease etc. Hip replacement surgery with navigation technology is minimally invasive procedure that warrants the precise configuration/alignment of the components of the hip implant which is of utmost importance for the efficient functioning of the new hip joint and making it hip last longer. Total Hip Replacement surgery is done in the hands of the most eminent and internationally trained orthopaedic and is recommended as the golden standards for the patient with advanced hip arthritis and deformed hip composition. It involves the replacement of the damaged and worn out hip joint structures with the artificial hip implants known as prosthesis. The prosthesis consists of
- A cup- which replaces the acetabulum (hip socket)
- A metal stem (femoral stem)- which replaces the neck of the femur (thighbone)
- A ball (metal or ceramic) – which replaces the head of the femur.
- An infrared navigation camera
- Smart instruments with the light emitting diode technology (LED) and
- A computer with specialized navigation software for surgery
- Optimal implant fitting with fine adjustment that abets to extend the implant life
- Smaller incisions, minimum muscle disruption, early recovery due to decreased rehabilitation period making this procedure less invasive.
- Offers better visualization of the structures and anatomy which is predominantly essential in minimally invasive procedures.
- Provides instantaneous feedback to the surgeons on the precise location of the implant and bids the potential to rectify any errors during the surgery.
