Nanodevice Monitors Hip Implant

Researchers at the University of Alberta have developed a nano-scale microsensor that can monitor the healing process after hip implant surgery. Following joint replacement, bone attaches to pores on the implant during osseointegration. The microsensor is then able to monitor the amount of fixation of the bone tissue to the implant. Additionally, the porous surface of the device allows for greater stability of the joint after fixation. The device is permanent and powered by kinetic motion of the body. Furthermore, the device does not transmit data until prompted by a physician. Doctors hope that the device will reduce the rehabilitation time and possibly the wait time for hip replacement candidates.
