Breast implants may impede ECG and lead to false heart attack diagnosis
Breast implants may impede an electrocardiogram (ECG) and could result in a false heart attack diagnosis, according to research by the European Heart Rhythm Association (EHRA), a registered branch of the European Society of Cardiology (ESC).

Painful knee prosthesis: loose, infected or both?
The implantation of knee and hip joints is considered one of the success stories of recent years. But periprosthetic joints infections (PJI) are one of the severe complications, with an infection rate of 2%. The probability of revision surgery increases with concomitant diseases such as rheumatoid arthritis, with fracture prosthesis or after previous surgery.

Reduction of infection risk in femoral head fractures by 66%
Good news for World Antibiotics Day on November 18th. As local substances carriers, antibiotic-loaded bone cements from Heraeus help in the battle against implant-associated infections in orthopaedics and trauma surgery to prevent infection. This is demonstrated by a new randomised study from Great Britain in which the use of double-loaded antibiotic bone cement following femoral head fracture…

Screws that fit the body’s notches
Complex bone fractures are often set with titanium or steel screws and plates. However, if these remain in the body for some time, they can cause health problems. A new bioceramic screw nail has the capacity of replacing the currently used metal components. It can be easily introduced into bone and does not have to be removed.

Using ultrasound to achieve permeability of blood vessels
CarThera, a French company based at the Brain and Spine Institute (ICM), that designs and develops innovative ultrasound-based medical devices to treat brain disorders, announces the publication on initial successes in disrupting the blood-brain barrier (BBB) with the use of ultrasound. This has been achieved in association with teams from the Assistance Publique-Hôpitaux de Paris (the Greater…

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.

Using 'Pacemakers' in spinal cord injuries
Researchers from Charité – Universitätsmedizin Berlin and EPFL, Lausanne have succeeded in restoring motor function following spinal cord injury. The researchers were able to show that coordinated muscle movement is the result of alternating activation patterns emanating from the spinal cord. Newly-developed implants, which use electrical stimulation to mimic these signals, were used to…

Modular partial wrist implant may help with pain
Studies are underway to determine if a new modular partial wrist replacement will allow for better movement and last longer than traditional implants for people seeking relief from painful wrist arthritis. Although current options such as total wrist replacement and wrist fusion can alleviate pain, patients are often limited in performing certain activities after surgery.

Improved brain implants
By implanting electrodes in the brain tissue one can stimulate or capture signals from different areas of the brain. These types of brain implants, or neuro-prostheses as they are sometimes called, are used to treat Parkinson's disease and other neurological diseases.
Printing implants with the laser
Whether for individual micro-implants or for micro-implants with medicine depots – additive processes are ideally suited for manufacturing such components. In the project “REMEDIS”, scientists at the Laser Zentrum Hannover e.V. (LZH) have established a highly automated laser melting process to produce or coat implants made of platinum, nickel-titanium (NiTi) or stainless steel.

Getting the perfect fit for artificial hips
When a patient receives a new hip, it is usually adjusted only approximately to leg length. Greater accuracy requires a more precise measuring process as well as adjustable implants. Now, a new type of measurement method coupled with a modular implant should allow orthopedic surgeons to precisely calibrate leg length after the operation so it matches its original length.

DIEP flap reconstruction
In France, every year 15,000 women undergo complete or partial mastectomy due to breast cancer. Only about a third of them, i.e. around 5,000 patients, use the possibilities reconstructive surgery offers and 70 percent of those women opt for an implant although it is associated with a risk of infection because the body might react negatively to the foreign object.
ESC recommends implant-based remote monitoring

Implantable cardiac monitors
Syncope (fainting) is a leading cause of hospital emergency visits. In almost 10% of patients, syncope has a cardiac cause; in 50%, a non-cardiac cause, and in 40% the cause of syncope is unknown. Syncope is difficult to diagnose as syncopal episodes are often too infrequent and unpredictable for detection with conventional monitoring techniques.
