Computer Assisted Hip Replacement Surgery in India
Computer Guided Surgery is also known as Image Guided Surgery Or Surgical Navigation Minimally invasive hip replacement surgery is a new type of surgery that can have you back on your feet faster than ever before. Thanks to a smaller incision, there is less trauma to the underlying muscles and soft tissues resulting in a smaller scar, less post-operative pain and a faster return to normal activities. In fact, minimally invasive hip replacement surgery may allow faster recovery compared to traditional hip replacement surgery.
Minimally invasive Hip Replacement surgery
Minimally invasive surgery represents a new way to perform hip replacement surgery. It involves surgical techniques that are easier on your tissues and allow the procedure to be performed through a smaller soft tissue "window." The payoff for patients is less pain and a faster recovery.
Less Pain : - Trauma caused by tissue damage causes pain and swelling during part of the normal healing process. Since less invasive surgery requires far less cutting and dissection of normal tissues, the end result is less pain during recovery.
Faster Recovery : - With minimally invasive surgery, the time needed in the hospital to gain independence and achieve comfort is shortened considerably.

Who is a candidate for minimally invasive hip replacement ?
Generally, anyone can benefit from a less invasive surgical technique. In some cases, due to the size or weight of the patient, the incision must be extended, but the trauma to the surrounding tissues will still be reduced when compared to traditional surgery. Your orthopaedic surgeon will try to keep the incision as small as possible, but there are times when the patient is best served by a larger incision.
Minimally invasive hip replacement can have you back on your feet faster than ever before. With stronger, potentially longer-lasting implants like OXINIUM* Oxidized Zirconium implants, you increase your ability to achieve greater range of motion in your hip as well as your ability to enjoy more of life's activities.
Talk to your orthopaedic surgeon to determine if minimally invasive hip replacement and OXINIUM implants are the right options for you.

Computer-assisted hip replacement surgery
Computer-assisted hip replacement surgery gives orthopaedic surgeons greater ability to perform less invasive procedures due to the enhanced surgical visualization. It also allows more accurate hip implant alignment and positioning by providing an advanced connection to medical technologies.
Computer-assisted hip replacement software helps surgeons visualize more than what can normally be seen through incisions and takes critical measurements throughout the surgery that are not possible without the assistance of computers.
How computer-assisted surgery works
Before beginning the hip replacement procedure, your surgeon helps the computer locate specific landmarks and take critical measurements of your body. Once the computer has this basic information, it can track the precise position of your leg and pelvis, the hip implant and the surgeon's instruments at all times during your surgery.
Throughout the surgery, the computer provides constant feedback and information to your surgeon. Your orthopaedic surgeon still does all of the work. The computer simply puts together the information coming in from the instruments and tells your surgeon where the precise implant position should be.
Given that every patient is different, this real-time, patient-specific, computer-guided accuracy is unmatched in the history of hip replacement surgery.
What are the patient benefits of computer-assisted surgery ?
Computer assisted surgery gives orthopaedic surgeons greater capabilities to perform less invasive procedures due to enhanced visualization. A smaller incision made during your hip replacement surgery means less trauma to the underlying muscles and soft tissues as well as less blood loss. This leads to a shorter hospital stay, shorter rehabilitation and a faster return to a greater quality of life.
Because computer-assisted surgery allows more precise alignment and placement of the hip implant it may also extend the lifespan of your hip replacement by reducing uneven wear. It also may help increase your range of motion.
In essence, computer-assisted surgery is like a GPS system for orthopaedic surgeons. It allows for longer-lasting implants and fewer complications. Talk to your orthopaedic surgeon to find out if computer-assisted hip replacement surgery is an available option for you.
Positioning of Implants Is Critical
While you may not realize it, one of the most critical aspects of a joint replacement surgery is to ensure proper positioning of the implanted joint. An incorrectly aligned joint can lead to early wear and loosening of the joint replacement. Similar to the alignment of the wheels on your car, a poorly aligned joint replacement will cause problems with early wear of the replacement.
In an effort to prevent early wear and loosening of the joint replacement, surgeons are constantly searching for ways to ensure the implant is properly positioned. A computer-assisted surgery is one additional check to confirm proper placement of the joint replacement. Your surgeon can still check with standard referencing instruments that the positioning is correct, and the computer can provide confirmation of the placement.
Should I Have Computer-Assisted Surgery ?
Computer-assisted surgery is just developing, and there is certainly not enough known about CAS to say that it will lead to better results than standard surgical procedures. CAS has been shown to make it less likely that limb alignment problems will occur after knee replacement surgery, but the computer models do not eliminate the chance of these errors being made. Furthermore, computer modeling does not take into account the soft tissues around the joint, which are as critical as the bone-alignment of the extremity. Therefore, current CAS only address a part of the problem of implant alignment.
CAS is an interesting development, but it is just that at this point. Efforts are being made to develop computer models that also take into account the soft tissues around the joint, so that a joint replacement implant can be as accurately placed as possible.
