New Implant-Based Technologies in the Spine

Vertebral compression fractures (VCFs) may result in a kyphotic deformity which can cause potential systemic complications secondary to respiratory and gastrointestinal dysfunction. The use of implants in the spine for VCF treatment represents a paradigm shift away from cement injection on its own, aiming to combine the analgesic and stabilizing effect of injecting cement into the vertebral body with vertebral height restoration and kyphotic angle correction. Spine implants which can be used for VCF treatment include stents, jacks, PEEK cages and fracture reduction systems. Lumbar spinal stenosis (LSS) with neurogenic intermittent claudication is one of the most commonly occurring spinal conditions, usually affecting people older than 50, which can cause disability and a reducted quality of life. Percutaneous interspinous spacers for the relief of symptoms caused by spinal stenosis can be used in patients who are not surgical candidates. The purpose of this article is to describe the basic concepts of spinal implantation in patients with VCF or spinal stenosis. The role of biomechanics and the different types of implants will be described. Controversies concerning techniques and products will be addressed. Finally, the necessity for an individually tailored approach for the use of different implants in different cases and anatomic locations will be emphasized. © 2018, Springer Science+Business Media, LLC, part of Springer Nature and the Cardiovascular and Interventional Radiological Society of Europe (CIRSE)

Detectors for the South Pole Telescope

AbstractThe South Pole Telescope (SPT) is a 10–m mm/sub-mm telescope at the Amundsen-Scott South Pole Station. It's primary science goals consist of a galaxy cluster survey for understanding Dark Energy and probing the physics of Inflation through the CMB polarization. Both science goals require exceptional sensitivity necessitating focal planes with many optical elements. The focal planes of the SPT utilize Transition Edge Sensor (TES) bolometers to build arrays of nearly 1000 detectors. In this talk, I will present the TES bolometer technology for both the first SPT focal plane and its upcoming upgrade to a polarization sensitive array
