The Heraeus Symposium at DKOU

Challenges of periprosthetic infection

Periprosthetic joint infection (PJI) is on the increase internationally. In Germany, for example, around 14,500 cases of PJI in hip and knee replacements occur annually. 5,100 of those are caused by multidrug resistant pathogens. ‘Eighty-seven percent of those affected die within five years,’ orthopaedic surgeon Professor Rudolf Ascherl MD pointed out during the Heraeus Symposium held at the…

'ScoliBot' offers superhuman precision

New robots improve spinal straightening

ScoliBot, a new robotic system, could perform spinal surgery to a higher degree of accuracy than human counterparts. Devised by a team from Nottingham Trent University (NTU), the system has two robotic arms that semi-autonomously drill holes in individual vertebrae in procedures to straighten the spines of patients with conditions such as scoliosis or kyphosis. Leading the project, Professor…

Vertebral body replacement (VBR)

Help for cervical spine

Omnia Medical’s ‘Boxcar’ has been granted the first US FDA 510(k) clearance for a cervical vertebral body replacement (VBR) system manufactured from PEEK-OPTIMA HA Enhanced polymer. The system has been designed for use in cervical-corpectomy procedures – the replacement of a collapsed, damaged, or unstable vertebral body located in the cervical spine. Robert Gewirtz, MD - Neurosurgeon,…

Flexible medical robot accelerates healing

Meet 'Robert', your robotic physio­therapist

Scenario: A physiotherapist arrives in a ward pushing a new device towards a patient in bed. There, she introduces rehabilitation robot Robert and points to its multi-jointed arm. She places a cuff around the patient’s lower leg to link it to Robert’s arm and presses the start button; Robert raises the leg slightly. Manually, the physiotherapist performs movements, which Robert memorises to…

Brain signals control a four-limb robotic system

Tetraplegic moves towards taking walks

Thanks to a four-limb robotic system controlled by brain signals, a patient with a cervical spinal cord injury could walk and control both arms for the first time in a proof of concept. Developed by CEA (French Alternative Energies and Atomic Energy Commission), the system is driven via the long-term implant of a semi-invasive medical device to record brain activity. ‘This device is an…

Repetitive stress injuries

Selfie elbow – yes, this is actually a thing

Specialists are seeing more and more repetitive stress injuries (RSI) from overuse of smartphones and tablets ­– the main instigators of emerging conditions like texting thumb and selfie elbow, notes UT Southwestern rehabilitation specialist Dr. Renee Enriquez. “With all overuse injuries, rest is the most important part of recovery. Complete rest is best, but since technology is a required…

"Smart" knee implant could be the future of joint replacements

Smart knee implants may soon be a reality thanks to research conducted by a team including faculty at Binghamton University, State University of New York. Knee replacement surgery is the most common joint replacement procedure, with the number of surgeries increasing every year. Many of those surgeries are done to replace an older implant or one that has worn out. Increasingly, this surgery is…

The knee – correlations of MRI and arthroscopy

Magnetic resonance imaging (MRI) exams of the knee are essential to orthopedic surgeons for diagnosing the cause of symptoms in patients with knee pain and planning arthroscopic treatment. Yet the surgeons who treat patients based on knee MRIs and the radiologists who interpret those knee MRIs often work in their own silos of specialization, rarely communicating and sharing information, according…

Infection control

Local antibiotics improve results

Hip and knee joint surgeries are among the most common procedures in orthopaedics and trauma surgery and complications can occur. Rare, but serious, among these is periprosthetic joint infection (PJI), which causes high costs in healthcare and stress for patients. PJI is caused by microorganisms that form a biofilm on the surface of the implant and, in this sessile state, they are difficult to…

Understanding Bechterew's disease

Autoimmune diseases like Bechterew’s disease direct our immune systems agains our own bodies. Now, researchers at Jacobs University Bremen have come one step closer to understanding the molecular mechanisms of the disease also known as ankylosing spondylitis. It is characterized by long-term painful inflammation of the joints and deformation of the spine. One suspected cause is a particular…

What your walk says about your health

The way you walk can reveal current and future health problems. New research from Halmstad University suggests the use of wearable sensors for analysing your movement. This can potentially result in early detection of for example Parkinson’s disease, dementia, multiple sclerosis and other neuro-physiological disorders. Many of our body systems, such as the cardio-vascular system and the…

After joint replacement: Novel method of isolating infecting organisms

Joint replacement surgery carries the risk of developing an infection in the replaced joint, which can lead to a so-called revision or re-do of the joint replacement. However, current diagnostic practices can fail to detect bacteria in 30-50 percent of clinical cases, complicating or delaying appropriate treatment. Thomas Jefferson University researchers have found that genomic analysis using…

Artificial nerve response

Computer model simulates sense of touch from the entire hand

Neuroscientists from the University of Chicago have developed a computer model that can simulate the response of nerves in the hand to any pattern of touch stimulation on the skin. The tool reconstructs the response of more than 12,500 nerve fibers with millisecond precision, taking into account the mechanics of the skin as it presses up against and moves across objects.

Lower limb trauma – reconstruction or amputation?

‘Amputation v. reconstruction’ – a vital issue – was debated by two leading surgeons during the Microsurgical Lower Limb Reconstruction session at the Advances and Controversies in Reconstructive Microsurgery (ACRM) 2016 conference, held in the United Kingdom this May. Consultant Plastic Surgeon Umraz Khan, from North Bristol NHS Trust presented a plastic surgeon’s view, while Ben…

Mimicking touch

Amputee feels texture with a bionic fingertip

An amputee was able to feel smoothness and roughness in real-time with an artificial fingertip that was surgically connected to nerves in his upper arm. Moreover, the nerves of non-amputees can also be stimulated to feel roughness, without the need of surgery, meaning that prosthetic touch for amputees can now be developed and safely tested on intact individuals.

Cells from cow knee joints used to grow new cartilage tissue

In an effort to develop a method for cartilage tissue engineering, researchers at Umeå University in Sweden successfully used cartilage cells from cow knee joints. By creating a successful method with conditions conducive to growing healthy cartilage tissue, the findings could help lead to a new treatment cure for osteoarthritis using stem cell-based tissue engineering. This is according to a…

World’s first bilateral hand transplant on a child performed

Surgeons at The Children’s Hospital of Philadelphia (CHOP) joined with colleagues from Penn Medicine recently to complete the world’s first bilateral hand transplant on a child. Earlier this month, the surgical team successfully transplanted donor hands and forearms onto eight-year-old Zion Harvey who, several years earlier, had undergone amputation of his hands and feet and a kidney…
