Living Things and Ecology : Artificial Joints/:Limbs

Year 8 Science

Arthritis Australia

Joint replacement involves replacing a damaged joint with an artificial joint. In the year ending December 2015 more than 102,000 hip and knee procedures were performed in Australia.

Osteoarthritis is a chronic and progressive condition that mostly affects the hands, spine and joints such as hips, knees and ankles. It is the most common form of arthritis and the predominant condition leading to knee and hip replacement surgery in Australia.

Joint disease, any of the diseases or injuries that affect human joints. Arthritis is no doubt the best-known joint disease, but there are also many others

Prosthesis, artificial substitute for a missing part of the body. The artificial parts that are most commonly thought of as prostheses are those that replace lost arms and legs

The New Daily

Rising obesity rates and an ageing population are projected to fuel the sharp increase in knee and hip joint replacements, which will cost the health system $5.32 billion in the next decade.

YALE medicine

Using MRI and CT scan images to obtain precise measurements, he produces a solid, three-dimensional model of the patient’s anatomy. This model is used to create custom tools and implants individually designed for each patient.

Scientists and engineers have made great strides in recent years with prosthetics and orthotics. In this programme we discuss how designers are striving to simulate the anatomy and physiology of missing limbs. Though some prosthetics are simple and minimally functional, others are complex bionic artificial limbs with improved designs, using advanced hydraulics, lightweight materials such as carbon fibre, and computer microprocessors and sensors.

A prosthesis is much more than a medical device, it also completes a wearer’s sense of wholeness.

Bionic technology is removing physical barriers faced by disabled people while raising profound questions of what it is to be human. From DIY prosthetics realised through 3D printing technology to customised AI-driven limbs, science is at the forefront of many life-enhancing innovations.

Albert Chi, MD explains the crossroads of breakthrough surgery and breakthrough technology revealing the future of prosthetics that will change the world - the Modular Prosthetic Limb (MPL), delivering hope and possibility to all who have lost an upper extremity.

Stryker Joint Replacement is turning out components for artificial hips and knees using GE Additive’s Concept Laser printers at its new manufacturing plant in Cork, Ireland. The titanium alloy parts have surfaces with good porosity for bio-integration, an important property for adhesion in cementless artificial joints. The 3D technology also offers unprecedented design freedom.

Osteoarthritis is one of the most common forms of arthritis (inflammation in the joints), affecting around 31 million Americans. It arises when cartilage (the tissue that covers the ends of bones) in our joints begins to break down, a process that is triggered by overuse and/or aging, and which gradually worsens over time. Cartilage provides padding that allows the bones in joints to glide smoothly against each other when we move. Without this padding, movement brings pain, stiffness, and swelling

For several years, a number of Swedes have been living with a unique mind-controlled arm prosthesis, and the world's most integrated human-machine interface. They have a permanent connection between the prosthesis and the skeleton, muscles and nerves in their upper arm – and can even sense how hard they grip with their artificial hand.

Health Direct Australia

An amputation is the removal of the whole or part of an arm, hand, leg or foot. Amputation is always a last resort and it will not be done unless it is absolutely necessary for a person's health

Arm Dynamics

Arm Dynamics provides comprehensive, upper-limb-focused prosthetic rehabilitation care to amputees and those with congenital limb differences. Our unique approach maximizes each patient’s rehabilitation and empowers them to regain their independence, pursue their occupational goals and live a normal, active lifestyle.

Science Daily

Mind-controlled arm prostheses that 'feel' are now a part of everyday life.

OPS

OPS has access to all the latest technological innovations that are available in the Prosthetic and Orthotic profession. We incorporate this technology into Prostheses where appropriate to achieve the best possible function, comfort and safety outcomes.

Prosthetic Developments

We are living in exciting times, especially where the development of prosthetic technology is concerned. The past few years saw quantum leaps in research, the trajectory of which points to understanding the human brain and anatomy to create prostheses that increasingly feel more natural to use. Better designs promise a better quality of life for prosthetic users around the world, and there is no doubt that we will see more improvements in the following prosthetic tech this year.

TMF

Advances in prosthetics are helping to improve that world for amputees, even if the world around them does not necessarily improve.  And these developments are happening fast. To get a clearer picture of what lies ahead, whom better to ask than a prosthetic wearer who develops robotic prostheses?

Medical Xpress

CU Boulder biomedical engineer Jacob Segil is working to bring back that sense of touch for amputees, including veterans of the wars in Iraq and Afghanistan.
