Orthopaedic smart device provides personalized medicine

15.02.2012
Tiny wireless sensors enable physicians to collect objective, quantifiable information

Imagine a smart sensor customized to provide vital, real-time information about a patient's recent orthopaedic surgery. Instead of relying on X-rays or invasive procedures, surgeons will be able to collect diagnostic data from an implantable sensor.

A study presented at the Orthopaedic Research Society 2012 Annual Meeting in San Francisco outlined this remarkable technology that promises to make post-surgical diagnosis and follow up more precise, efficient, and cost-effective.

"The sensor provides opportunities to make specific and detailed diagnostics for a particular patient and to tailor care based on very objective and quantitative measures," said Eric H. Ledet, PhD, Assistant Professor, Rensselaer Polytechnic Institute.

"This highly unique sensor is very small (4 mm diameter and 500 microns thick), is wireless, batteryless, and requires no telemetry within the body. Its simplicity makes it less prone to failure and very inexpensive to produce," Dr. Ledet explained.

The orthopaedic implant acts as a carrier for the sensor. The wireless sensor can monitor load, strain, motion, temperature, and pressure in the challenging in vivo environment. It can be placed into a spinal or fracture fixation implant, for example, to determine the patient's progress.

"For the patient that is progressing well, the information from the sensor enables the physician to determine that the patient can return to work without risk of injury," said Dr. Ledet. "The number of lost days at work is reduced."

It can also alert the physician to potential problems, indicating that additional interventions may be needed. "By maintaining a simple platform, we're able to customize the sensor and make it very, very small so it can be incorporated into a lot of different implants," said Rebecca A. Wachs, MS, Rensselaer Polytechnic Institute. "By changing one small parameter, we can change the sensitivity of the sensor itself."

Dr. Ledet reports a number of major breakthroughs with the sensor technology in the last eighteen months. Although the researchers are manually producing the sensor, they anticipate it will eventually be mass produced—driving the price down further.

About the Orthopaedic Research Society (ORS):

The Orthopaedic Research Society (ORS) is the pre-eminent organization for the advancement of musculoskeletal research. It seeks to transform the future through global multidisciplinary collaborations—focusing on the complex challenges of orthopaedic treatment. The ORS advances the global orthopaedic research agenda through excellence in research, education, collaboration, communication and advocacy. The ORS Annual Meeting and publication of the Journal of Orthopaedic Research provide vital forums for the musculoskeletal community to communicate the current state of orthopaedic research.

Researchers from the University of Hamburg in Germany, in collaboration with colleagues from the University of Aarhus in Denmark, have synthesized a new superconducting material by growing a few layers of an antiferromagnetic transition-metal chalcogenide on a bismuth-based topological insulator, both being non-superconducting materials.

While superconductivity and magnetism are generally believed to be mutually exclusive, surprisingly, in this new material, superconducting correlations...

Im Focus: Designing Architecture with Solar Building Envelopes

Among the general public, solar thermal energy is currently associated with dark blue, rectangular collectors on building roofs. Technologies are needed for aesthetically high quality architecture which offer the architect more room for manoeuvre when it comes to low- and plus-energy buildings. With the “ArKol” project, researchers at Fraunhofer ISE together with partners are currently developing two façade collectors for solar thermal energy generation, which permit a high degree of design flexibility: a strip collector for opaque façade sections and a solar thermal blind for transparent sections. The current state of the two developments will be presented at the BAU 2017 trade fair.

As part of the “ArKol – development of architecturally highly integrated façade collectors with heat pipes” project, Fraunhofer ISE together with its partners...
