OrthAlign, Inc., a privately held U.S.-based medical device and technology company providing orthopedic surgeons with advanced precision technologies, announced today that the Japanese Ministry of Health, Labour, and Welfare (JMHLW) has approved Direct Anterior HipAlign® for use in supine position Total Hip Arthroplasty (THA) surgeries and UniAlign™ for use in Unicompartmental Knee Arthroplasty (UKA) surgeries in Japan. “I am very excited that OrthAlign technology will be available for use in Japan for supine position THAs and UKAs,” said Yukihide Minoda, MD, PhD of Osaka City University in Osaka, Japan. “I already use KneeAlign® for my TKAs and have found it to be a very important part of my surgeries. Clinically, it has been very valuable for my patients in Japan and I am very happy with the excellent outcomes. I expect the same with these new technologies.” Recent statistics have shown that the direct anterior (supine position) approach is growing in popularity amongst Japanese surgeons as it arguably leads to quicker recovery, less pain, more normal function for Japanese patients after a hip replacement, and is more minimally invasive. HipAlign provides accurate cup placement positioning and does not require any pre-operative imaging, intraoperative fluoroscopy, or additional personnel in the operating room to control components outside of the sterile field. Based on FDA cleared bench test data, HipAlign technology provides cup placement accuracy of ±3°, with at least 97% confidence. The system accounts for pelvic tilt when measuring the abduction and anteversion angles of the acetabular cup. UniAlign establishes the mechanical axis of the tibia, determining the varus/valgus angle and the posterior slope angle of the cutting block relative to the tibia, for the transverse resection. The system has been validated in simulated use testing to achieve resection accuracy of ±2.0° in the coronal plane, ±3.0° in the sagittal plane and ±2.0 mm in depth. This accuracy has been validated with at least 90% confidence. Just as KneeAlign and Posterior Approach HipAlign have been distributed in Japan through OrthAlign's partner ZimmerBiomet Japan, so too will Direct Anterior HipAlign and UniAlign. “We are very pleased with the Japanese Ministry’s approval for use of Direct Anterior HipAlign and UniAlign in Japan,” said James Young Kim, OrthAlign’s Vice President and General Manager of International. “There were approximately 20,000 supine position THAs and 8,000 UKAs completed in Japan during 2016, and these are the fastest growing procedures in joint replacement in the country. Japan is extremely important for OrthAlign's international growth strategy and we will continue providing new technologies that address the market's needs, following the successes of KneeAlign and Posterior Approach HipAlign. We are thrilled to be expanding our partnership with ZimmerBiomet Japan and hope we can continue our contribution in raising the standard of care for Japanese joint replacement surgeries.” OrthAlign is a privately held medical device and technology company, developing advanced technologies that deliver healthier and more pain-free lifestyles to joint replacement patients, globally. We provide healthcare professionals with cutting edge, computer-assisted surgical tools that seamlessly and cost-effectively deliver vital data and clinical results to optimize outcomes for our patients.

This clamp-type ammeter has a flexible substrate of which an inner wall is configured to be able to deform into a substantially cylindrical shape. The clamp-type ammeter has a plurality of magnetic sensor elements disposed at the inner wall of the flexible substrate. The clamp-type ammeter has a tube of which one end is connected to the flexible substrate. The clamp-type ammeter has an operation unit that is connected to the other end of the tube and that can operate the deformation of the flexible substrate.

A control computation unit causes an optical modulator to change a polarization state to shift a phase of polarized light with which an object is irradiated, computes a spatial gradient of tomographic distribution of phase difference of an interference signal on the basis of phase differences of interference signals each obtained by each phase shift of the polarized light, and visually displays tomographic distribution of spatial gradient in association with tomographic distribution of stress on the display device. The control computation unit computes deformation rate vector distribution at cross-sectional positions of the object on the basis of optical interference signals, and further computes tomographic distribution of strain rate tensor. The control computation unit then computes tomographic distribution of mechanical property value from the tomographic distribution of stress and the tomographic distribution of strain rate tensor, and visually displays the tomographic distribution of mechanical property value.

According to an aspect of the present invention, a drive control apparatus is provided. The drive control apparatus receives a transmission signal, where a plurality of control signals is superimposed on a power transmission voltage, through an electric wire and drives and controls a device to be controlled. A detection frequency is set in the drive control apparatus. One of the plurality of control signals is a control signal for controlling the device to be controlled. The frequency of the control signal is close to the detection frequency. The drive control apparatus includes a drive voltage generator which generates a first drive voltage from the power transmission voltage of the transmission signal and drives the device to be controlled, a detection current generator which generates a detection current whose frequency is the detection frequency, a magnetic element through which the detection current flows and which generates an output corresponding to a result of multiplication of the detection current and a current flowing through the electric wire, and a signal processor which detects the control signal for controlling the device to be controlled from the output from the magnetic element and controls the device to be controlled based on the control signal.

This article presents our take on the area of bulk ultrafine-grained materials produced by severe plastic deformation (SPD). Over the last decades, research activities in this area have grown enormously and have produced interesting results, which we summarise in this concise review. This paper is intended as an introduction to the field for the "uninitiated", while at the same time highlighting some polemic issues that may be of interest to those specialising in bulk nanomaterials produced by SPD. A brief overview of the available SPD technologies is given, along with a summary of unusual mechanical, physical and other properties achievable by SPD processing. The challenges this research is facing - some of them generic and some specific to the nanoSPD area - are identified and discussed. © 2012 Acta Materialia Inc. Published by Elsevier Ltd.
