The German prosthetics company Ottobock has associated with orthopaedic surgeon Dr Aditya Khemka to introduce the osseointegration technology an innovative procedure to help create bionic prostheses for amputee patients in India.
Osseointegration is a radical procedure where a skeletal connection with the prosthetics is achieved through a titanium implant in the bone of the amputee.
The procedure creates an interface that connects directly onto a prosthetic limb. The resulting bionic leg will be composed of bone and have muscle growth around the upper part of the rod and a system of hydraulics, and microprocessors will help to drive the lower limb in a way more natural by enabling the amputees to control the limb more intuitively.
“Osseointegration is a new dimension to the process in which amputation reconstruction is done”, said Dr Aditya Khemka who has super-specialisation in the procedure, in a statement. He is currently practising as a consultant in multiple super speciality hospitals in Mumbai and specializes in hip, knee, and osseointegration surgery. He has a keen interest in revision hip and knee arthroplasty (joint replacements), especially total/partial femur replacements.
“The most important and hence a ‘bottleneck’ part of the prosthesis is the socket,” he says.
The socket is custom made and skill dependent whereas components like knee and foot are prefabricated and standardised. So if the socket is not right, even with the best of components, the prosthesis will not deliver a complete outcome.
“Osseointegration deletes socket issues leaving no scope for skin break-downs or discomfort. It offers many other benefits like quick removal and wearing of the prosthesis, better ‘feel’ of the ground below due to direct bone contact, etc. The outcome is always improved energy transfer and control of the prosthetic leg restoring mobility in the patient. We are trying to create real bionic amputees here!” added Dr Khemka.
Bernard O’Keeffe, Managing Director & Regional President, Asia Pacific, Ottobock said: “If after osseointegration, an inexperienced or unskilled healthcare professional fits the prosthetic components, it can lead to an adverse impact on the implant and the outcomes can be damaging for the patient. We, therefore, ensure that we draw from 100 years of our company’s experience and use globally established protocols to fit osseointegration patients with prostheses.”
