Double-amputee Jason Koger used to fly to visit a clinician when he wanted to adjust the grips on his bionic hands. Now, he's got an app instead. Koger this week demonstrated the i-limb ultra revolution, a prosthetic developed by the British firm Touch Bionics. Using a stylus and an iPhone, Koger can choose any of 24 grip patterns that best suit his needs. http://medicalxpress.com/news/2013-05-app-amputees-bionic.html Other Fri, 03 May 2013 13:40:26 EST news286807210 Elderly or people with osteoporosis, smokers, diabetics or people who have had cancer are sometimes not eligible to receive dental implants as their bones are unable to correctly integrate the new prostheses which replace the root. Researchers at the Universitat Jaume I (UJI) in Castellón have developed an implant coating with a novel biodegradable material aimed at people with bone deficit. It will also increase the overall success rate of implants through an enhanced biocompatibility and reduce the time of osseointegration or bone integration. http://medicalxpress.com/news/2013-04-success-tooth-implants.html Dentistry Mon, 29 Apr 2013 09:28:22 EST news286446495 For the first time an operation has been conducted, at Sahlgrenska University Hospital, where electrodes have been permanently implanted in nerves and muscles of an amputee to directly control an arm prosthesis. The result allows natural control of an advanced robotic prosthesis, similarly to the motions of a natural limb. http://medicalxpress.com/news/2013-02-world-premiere-muscle-nerve-controlled-arm.html Medical research Fri, 22 Feb 2013 09:04:26 EST news280746248 Elderly or people with osteoporosis, smokers, diabetics or people who have had cancer are sometimes not eligible to receive dental implants as their bones are unable to correctly integrate the new prostheses which replace the root.

The control of these prostheses, which is currently linear, may soon be improved even further: with pattern recognition. In collaboration with Ottobock, this method is currently being tested and developed at the Christian Doppler Laboratory for the Restoration of Extremity Functions, which is being opened today (8th May) and which is being headed up by Oskar Aszmann from the Department of Plastic and Reconstructive Surgery at the University Department of Surgery at the MedUni Vienna, part of Vienna General Hospital.    http://medicalxpress.com/news/2012-05-hi-tech-prostheses-personalized-movement-pattern.html Surgery Tue, 08 May 2012 09:43:23 EST news255688979 If heart valves don't close properly, they are replaced. Conventional treatment of venous valve failure, however, has up to now always and exclusively been via medication. In future, an implant will assume the function of damaged valves -- and a new dispensing tool means these prostheses can be made using an automated process. http://medicalxpress.com/news/2012-03-implant-defective-venous-valve.html Other Thu, 08 Mar 2012 10:44:07 EST news250425840 Opening the door to the development of thought-controlled prosthetic devices to help people with spinal cord injuries, amputations and other impairments, neuroscientists at the University of California, Berkeley, and the Champalimaud Center for the Unknown in Portugal have demonstrated that the brain is more flexible and trainable than previously thought. http://medicalxpress.com/news/2012-03-brain-flexible-trainable-previously-thought.html Neuroscience Sun, 04 Mar 2012 13:00:09 EST news250084402 The World Health Organisation (WHO) on Tuesday intervened for the first time in the roiling global scandal over faulty breast implants, urging women with the devices to seek medical advice if they have any concerns. http://medicalxpress.com/news/2012-01-issues-guidelines-contested-breast-implants.html Other Tue, 17 Jan 2012 15:00:02 EST news246033414 Germany and the Czech Republic advised women Friday to have potentially faulty breast implants made by French firm PIP removed, but Britain said it was not convinced of the need. http://medicalxpress.com/news/2012-01-germans-czechs-french-breasts-implants.html Other Fri, 06 Jan 2012 18:44:42 EST news245097876 The US Food and Drug Administration warned a French maker of breast implants now feared to be at risk of rupture of "serious" quality control violations involving saline implants back in 2000. http://medicalxpress.com/news/2011-12-french-implant-maker.html Other Wed, 28 Dec 2011 00:53:46 EST news244255976 The founder of the French firm that made breast implants feared to be at risk of rupturing has admitted using non-approved but non-toxic silicone gels, his lawyer said Tuesday. http://medicalxpress.com/news/2011-12-breast-implant-maker-non-approved-gels.html Other Tue, 27 Dec 2011 16:30:42 EST news244225833 Orthopaedic surgeons face a steep learning curve to get used to new prostheses, and the instruments and methods that go with them, before new total knee replacement procedures are as safe and effective as conventional methods. Patients who undergo the first 15 operations using a new device in a hospital are 48 percent more likely to need early revision surgery, than patients undergoing an operation to fit a prosthesis previously used in the hospital. The work by Mikko Peltola from the National Institute for Health and Welfare in Finland, and colleagues, is published online in Springer's journal, Clinical Orthopaedics and Related Research. http://medicalxpress.com/news/2011-12-patients-knee-joint-complications-technology.html Other Wed, 14 Dec 2011 10:25:23 EST news243080715 Since 2007 Transcatheter Aortic Valve Implantation (TAVI) has become an alternative treatment for elderly patients with severe aortic stenosis at high risk for surgical aortic valve replacement. At present, durability and hemodynamic performance of transcatheter aortic valves remain unclear. Our single center data of the German Heart Center in Munich demonstrates a sustained improvement of hemodynamic performance up to 3 years after CoreValve implantation. http://medicalxpress.com/news/2011-08-hemodynamic-results-transcatheter-aortic-valve.html Cardiology Tue, 30 Aug 2011 11:38:32 EST news233923080
