Osseointegration Group of Australia

Last updated

The Osseointegration Group of Australia is an organisation founded by Sydney orthopedic surgeon and osseointegration specialist Dr Munjed Al Muderis. The Osseointegration Group of Australia Team is made up of specialists from various fields including prosthetics, physio, rehabilitation, anesthesia and psychology.

Osseointegration is the direct structural and functional connection between living bone and the surface of a load-bearing artificial implant. A more recent definition defines osseointegration as "functional ankylosis ", where new bone is laid down directly on the implant surface and the implant exhibits mechanical stability. Osseointegration has enhanced the science of medical bone and joint replacement techniques as well as dental implants and improving prosthetics for amputees.

Dr. Munjed Al Muderis is an Australian Associate Professor in orthopaedic surgery, author and human rights activist. He has done pioneering work on prosthetics, especially on titanium devices.

Osseointegration surgery involves the insertion of a titanium implant into the femur or tibia of an amputee. The implant than connects with an external prosthetic component which eliminates the need for traditional rigid socket prosthetics. The surgery and the follow up from the team aims to provide patients with a greater quality of life through increased mobility and reduced discomfort. [1] The group offers support before and after the surgery providing rehabilitation, physiotherapy and pain management. [2]

Titanium Chemical element with atomic number 22

Titanium is a chemical element with the symbol Ti and atomic number 22. It is a lustrous transition metal with a silver color, low density, and high strength. Titanium is resistant to corrosion in sea water, aqua regia, and chlorine.

Femur most proximal bone of the leg for tetrapode vertebrates, longest bone for humans

The femur, or thigh bone, is the proximal bone of the hindlimb in tetrapod vertebrates and of the human thigh. The head of the femur articulates with the acetabulum in the pelvic bone forming the hip joint, while the distal part of the femur articulates with the tibia and kneecap forming the knee joint. By most measures the femur is the strongest bone in the body. The femur is also the longest bone in the human body.

Tibia larger of the two bones of the leg below the knee for vertebrates

The tibia, also known as the shinbone or shankbone, is the larger, stronger, and anterior (frontal) of the two bones in the leg below the knee in vertebrates, and it connects the knee with the ankle bones. The tibia is found on the medial side of the leg next to the fibula and closer to the median plane or centre-line. The tibia is connected to the fibula by the interosseous membrane of the leg, forming a type of fibrous joint called a syndesmosis with very little movement. The tibia is named for the flute tibia. It is the second largest bone in the human body next to the femur. The leg bones are the strongest long bones as they support the rest of the body.

Notable surgeries

The Osseointegration Group of Australia clinics at Norwest Private Hospital in Sydney are known worldwide as centres of excellence, according to NEWS. [3] Dr Al Muderis and the Osseointegration Group of Australia have treated several Paralympian, cancer patients and traumatic amputees from both Australia and overseas.

In 2011, Dr Al Muderis and the Osseointegration Group of Australia performed the first Australian osseointegration surgery on Paralympian Brendan Burkett. Burkett is an medal holding Australian swimmer who in his teen years was involved in a motorbike accident that caused the loss of his leg. His surgery was successfully performed at Macquarie University Hospital. [4]

In April 2012, Dr Al Muderis and the Osseontegration Group of Australia was responsible for the surgery provide an artificial limb for Marny Cringle, 42. Marny In a world first procedure, she became the first person in the world to be fitted with a bionic limb after lengthening her bone by two inches as the remaining stump after her amputation was too short for a prosthetic limb to be fitted. Her successful surgery set a precedent for possible achievements in the case of thousands other amputees.

Jamie Bertoux, a double amputee from London, was the first overseas patient to travel to Australia to have osseointegration surgery under the care of the Osseointegration Group of Australia. [6] Osseointegration patient Phil Coulson from Nelson in New Zealand became the first New Zealander to be fitted with a bionic leg. [7] Osseointregration Group of Australia conducted their first American implant surgery on Fred Hernandez in April 2013. [8]

In other firsts, Iain McGregor from New Zealand was the first patient in the southern hemisphere to go straight from amputation to bionic leg. [9] Miranda Cashin was the first congenital amputee to receive the surgery. [10]

In 2013 Dr Al Muderis and the Osseointegration Group of Australia met Michael Swain, a former British soldier in his Sydney clinic. Michael Swain was a British rifleman who was 20 years old when he lost his leg in the Taliban Bomb Blast in Afghanistan that took place in November 2009. [11] For 18 months, he tried learning how to walk with prosthetic legs but he was still relatively immobile. After osseointegration surgery, Swain, a double amputee has been able to return an active and mobile life.

Prosthesis Artificial device that replaces a missing body part

In medicine, a prosthesis or prosthetic implant is an artificial device that replaces a missing body part, which may be lost through trauma, disease, or a condition present at birth. Prostheses are intended to restore the normal functions of the missing body part. Amputee rehabilitation is primarily coordinated by a physiatrist as part of an inter-disciplinary team consisting of physiatrists, prosthetists, nurses, physical therapists, and occupational therapists. Prostheses can be created by hand or with Computer-Aided Design (CAD), a software interface that helps creators design and analyze the creation with computer-generated 2-D and 3-D graphics as well as analysis and optimization tools.

Dental implant surgical component that interfaces with the bone of the jaw or skull to support a dental prosthesis.

A dental implant is a surgical component that interfaces with the bone of the jaw or skull to support a dental prosthesis such as a crown, bridge, denture, facial prosthesis or to act as an orthodontic anchor. The basis for modern dental implants is a biologic process called osseointegration, in which materials such as titanium form an intimate bond to bone. The implant fixture is first placed so that it is likely to osseointegrate, then a dental prosthetic is added. A variable amount of healing time is required for osseointegration before either the dental prosthetic is attached to the implant or an abutment is placed which will hold a dental prosthetic.

Neuroprosthetics is a discipline related to neuroscience and biomedical engineering concerned with developing neural prostheses. They are sometimes contrasted with a brain–computer interface, which connects the brain to a computer rather than a device meant to replace missing biological functionality.

Ocular prosthesis type of craniofacial prosthesis

An ocular prosthesis, artificial eye or glass eye is a type of craniofacial prosthesis that replaces an absent natural eye following an enucleation, evisceration, or orbital exenteration. The prosthesis fits over an orbital implant and under the eyelids. Though often referred to as a glass eye, the ocular prosthesis roughly takes the shape of a convex shell and is made of medical grade plastic acrylic. A few ocular prostheses today are made of cryolite glass. A variant of the ocular prosthesis is a very thin hard shell known as a scleral shell which can be worn over a damaged or eviscerated eye. Makers of ocular prosthetics are known as ocularists. An ocular prosthesis does not provide vision; this would be a visual prosthesis. Someone with an ocular prosthesis is totally blind on the affected side and has monocular vision.

Targeted reinnervation enables amputees to control motorized prosthetic devices and to regain sensory feedback. The method was developed by Dr. Todd Kuiken at Northwestern University and Rehabilitation Institute of Chicago and Dr. Gregory Dumanian at Northwestern University Division of Plastic Surgery.

Computer-assisted surgery (CAS) represents a surgical concept and set of methods, that use computer technology for surgical planning, and for guiding or performing surgical interventions. CAS is also known as computer-aided surgery, computer-assisted intervention, image-guided surgery and surgical navigation, but these are terms that are more or less synonymous with CAS. CAS has been a leading factor in the development of robotic surgery.

A visual prosthesis, often referred to as a bionic eye, is an experimental visual device intended to restore functional vision in those suffering from partial or total blindness. Many devices have been developed, usually modeled on the cochlear implant or bionic ear devices, a type of neural prosthesis in use since the mid-1980s. The idea of using electrical current to provide sight dates back to the 18th century, discussed by Benjamin Franklin, Tiberius Cavallo, and Charles LeRoy.
