Wearable technology has become an important part of medicine, from tracking vital signs to disease diagnosis. In surgery, wearable technologies can now assist, augment, and provide a means of patient assessment before, during and after surgical procedures. Wearable technologies are applied before the patient even reaches the operating room, for example in prehabilitation, i.e. pre-treatment…
At their workplace, neurosurgeons often have to make compromises since most ORs were not designed with the specific needs of their discipline in mind.

Someone has a stroke every 40 seconds in the US, resulting in death every 4 minutes. Stroke is the leading cause of disability from a medical condition. When it happens, blood clots or bleeds kill a part of the brain – it goes dark – and can no longer control part of the body. People stop being able to walk, see, talk, or control their hand or arm the way they once did. Although treatments…

Physicians have been performing surgery with the assistance of x-ray technology for almost half a century. While this technology has been progressing steadily, its limitations continue to be a major challenge. Thus, many professionals agree: it's time for our method to be changed. Taiwan Main Orthopaedics Biotechnology introduced the worldwide first smart surgical glasses.
Spine deformities, such as idiopathic scoliosis and kyphosis (also known as “hunchback”), are characterized by an abnormal curvature in the spine. The children with these spinal deformities are typically advised to wear a brace that fits around the torso and hips to correct the abnormal curve. Bracing has been shown to prevent progression of the abnormal curve and avoid surgery. The…
New words are consistently spun out in the USA and frequently assimilated into ‘American English’. Take the term ‘hospitalist’ (little used in European English), which was coined by the renowned academic physician Robert M Wachter (University of California, San Francisco) and his colleague Lee Goldman, in an article published in the New England Journal of Medicine in 1996. Lisa Chamoff…

Scoliosis – typically defined as the curvature of the spine— affects around 3 out of every 100 people. While most cases of scoliosis are mild, some children develop spine deformities that continue to get more severe as they grow. An especially severe spinal curve can reduce the amount of space within the chest, making it difficult for the lungs to function properly.
Some six million people in the U.S. suffer from scoliosis, a sideways curvature of the spine. These include approximately 2 to 3% of adolescents who are diagnosed each year with idiopathic scoliosis, which is usually identified during puberty and progresses until skeletal maturity. One in 500 children today require treatment using spine braces and 1 in 5,000 need spinal surgery. The typical spine…
Twin girls born joined at the pelvic and hip region are recovering after separation surgery at Nationwide Children’s Hospital.

Results from a randomised controlled trial to compare the use of permanent radioactive implants (brachytherapy) with dose-escalated external beam radiotherapy in patients with prostate cancer show that the men who received brachytherapy were twice as likely to be cancer-free five years later. These results presented Professor James Morris, from the Department of Radiation Oncology, Vancouver…
Imaging the head and neck is only rarely practised in radiology training and is highly complex and particulate, which is why, during our discussion with Professor Birgit Ertl-Wagner, Head of MRI at the Institute for Clinical Radiology at Grosshadern Hospital, Ludwig Maximilian University, Munich, she pointed out that many radiologists are not comfortable with orientation around this area. When…
A research team from the University of Houston has created an algorithm that allowed a man to grasp a bottle and other objects with a prosthetic hand, powered only by his thoughts.
Radiotherapy always encounters particular challenges when a tumour is ‘mobile’. This is when radiotherapy must be carried out over several weeks. Within that period the tumour position, shape and expansion typically will keep changing. Thus radiotherapy needs continuous adaptation to maintain continuously precise radiation. Report: Chrissanthi Nikolakudi

Britain’s many new hospitals are more than brave architectural statements – they consistently win awards, inspire others and, above all, improve life for all who use them. Now another stunning creation is about to rise. Despite beginning life as a workhouse for the poor, and having to grow in bleak, outdated buildings, in its near 100- year history Alder Hey Children’s Hospital in Liverpool…

Last year, orthopaedics and sports medicine specialist Dr Rainer Burgkart (left), who is also a musculoskeletal researcher, selected a new C-Arm for use at the Technical University of Munich (Klinikum rechts der Isar). Recently, we asked him for the reasons behind this choice and his subsequent experience with this device.
Almost 25 years ago Michael Harrison of the University of California, San Francisco (UCSF) operated on the bladder of an unborn child. Almost eight years later, surgery was carried out on the diaphragm of an unborn child. His approach was controversial: a paediatric surgeon opened the abdomen and uterus of the pregnant woman, lifted out the foetus, performed the surgery and returned the foetus to…

Where are the most high-tech start-ups? That`s an easy one: Silicon Valley. But who comes in a close second? Surprisingly: Israel. Further: Israel ranks Number 1 in terms of availability of scientists and engineers and Number 2 in quality of higher education. The result of this impressive track record is a wide range of successful enterprises and products, particularly related to the life…
Surgery in the lower pelvic region often involves injury to or severing of nerve tissue. As in chronic diseases of the nervous system, the result can be pain, sensory disturbances or loss of function. Up to now the poor view of the nerves, partially formed of fine interwoven networks, has been one of the major problems – exacerbated by the strict division of skills between neurologists and…
Pain management due to spinal disorders and perispinal conditions represents an important health issue for the 21st century. Over the past decades, growing disability resulting from back pain has enabled development of alternative techniques and treatments to surgery.

Six years later, Dusan has become the first in the world to undergo a unique surgical procedure on the vertebral column in the neck area.
Increased diagnostic possibilities for orthopaedic patients.
The brain has few anatomical landmarks. During surgery it is critical that the neurosurgeon knows the exact locality of surgical instruments in relation to important brain structures. Thus neuronavigation systems have become standard tools for planning and guidance.
Fractures and disruptions of the pelvic ring are most often unstable, and can therefore jeopardise patients' standing and walking functions.
USA - Pressure and inflammation caused by a herniated disc in the lumbar spine, and particularly painful sciatica, can be relieved using a neuroradiological technique rather than surgery, according to Dr Jeffrey A Stone, head of Interventional Neuroradiology at the Georgia Medical College, who reported on his procedure at the 44th annual meeting of the American Society of Neuroradiology in San…
Total knee replacement (TKR) is a common procedure for treatment of severe gonarthrosis, but the outcome may be unsatisfactory due to primary malalignment of the prosthetic components. To improve precision and accuracy of this surgical procedure, CASPAR, a commercial robotic surgical system, has been adapted to assist the surgeon in preoperative planning and intraoperative execution of TKR
