Prosthetic (Prosthesis) devices, such as an artificial leg, that replace a part of the body. Prostheses are typically used to replace parts lost by injury (traumatic) or missing from birth (congenital) or to supplement defective body parts. Inside the body, artificial heart valves are in common use with artificial hearts and lungs seeing less common use but under active technology development. Other medical devices and aids that can be considered prosthetics include artificial eyes, palatal obturator, gastric bands, and dentures.
Researchers have developed a next-generation bionic hand that allows amputees to regain their proprioception. The results of the study, which have been published in Science Robotics, are the culmination of ten years of robotics research.
A large study on total hip replacement (THR) has shown that six out of ten of these prosthetic devices continue to function well after 25 years.
Researchers have found that the brain stores detailed information of a missing hand decades after amputation, regardless of whether amputees still experience phantom hand sensations.
A female Swedish patient with hand amputation has become the first recipient of an osseo-neuromuscular implant to control a dexterous hand prosthesis.
A new type of sensor could lead to artificial skin that someday helps burn victims 'feel' and safeguards the rest of us, University of Connecticut researchers suggest in a paper in Advanced Materials.
Rutgers researchers have discovered the long-sought reason that many people with joint replacements experience harmful inflammation and bone loss.
Researchers from North Carolina State University, the University of North Carolina and Arizona State University have developed an intelligent system for "tuning" powered prosthetic knees, allowing patients to walk comfortably with the prosthetic device in minutes, rather than the hours necessary if the device is tuned by a trained clinical practitioner.
Modern prostheses offer patients who have had a hand amputated much greater capability in everyday life than was possible with previous prosthetic reconstructive techniques. Redundant nerves from the amputated extremity can be surgically transferred to provide a much better connection between the patient's body and the prosthesis.
For surgeons getting ready to enter the operating room, the chances of contamination may be lower if they put their gowns on by themselves - without the assistance of a surgical technician, according to an experimental study in the Journal of Orthopaedic Trauma. The journal is published in the Lippincott portfolio by Wolters Kluwer.
Robert and Tiffany Cano of San Tan Valley, Ariz., have a new marriage, a new house and a 10-month-old son, Brody, who is delighted by his ability to blow raspberries.
In May 2000, Raul Silva was involved in a motorcycle accident in Baja California, Mexico, badly breaking his left femur, or thighbone. He underwent emergency surgery in Mexicali and, at first, everything seemed fine. Then an infection set in, worsened, and Silva eventually made his way to San Diego, where his left leg was amputated.
A Vanderbilt University Medical Centerstudy published today in JAMA shows that patients already at higher risk for gastrointestinal bleeding gain a marked protection from this risk when they take a proton pump inhibitor in combination with an oral anticoagulant.
New research led by the Hip Implant Prosthesis Study team at the University of Bristol Medical School has shown that small-head cemented metal-on-plastic hip replacements are the most cost-effective in men and women older than 65 years.
After a patient has been fitted with an artificial hip joint, sometimes the leg on that side ends up longer or shorter than before. This can lead to problems in the spinal column. A newly developed procedure enables leg length to be precisely adjusted during hip replacement surgery.
A new artificial joint restores important wrist-like movements to forearm amputees, something which could dramatically improve their quality of life.
Amputees who use powered prosthetic ankles may be able to avoid the energetic costs typically associated with prosthetics by cranking up the power provided by their devices.
Arizona State University researcher James Abbas is part of a multi-institutional research team that has developed a new prosthetic hand system with a fully implanted, wirelessly controlled neurostimulator that has restored "feeling" to a person with a hand amputation.
New research has revealed the impact a change in US guidelines had on the prescribing of antibiotic prophylaxis to prevent a life-threatening heart condition infective endocarditis in patients before undergoing invasive dental treatment.
Neuroprosthetics - implants containing multi-contact electrodes that can substitute certain nerve functionalities - have the potential to work wonders.
For the first time ever, a research team from the small innovative enterprise Biomimetix, implementing several NUST MISIS developments, has successfully implanted a biomimetic hybrid prosthesis imitating bone structure made from ultra-high molecular weight polyethylene and titanium alloy into a patient's femoral bone.
