Minimally Invasive Spine Technology and Minimally Invasive Spine Surgery: A Historical Review

By: Dr. Jeffrey Oppenheimer

The trend of using smaller operative corridors is seen in various surgical specialties. Neurosurgery has also recently embraced minimal access spine technique, and it has rapidly evolved over the past 2 decades. There has been a progression from needle access, small incisions with adaptation of the microscope, and automated percutaneous procedures to endoscopically and laparoscopically assisted procedures. More recently, new muscle-sparing technology has come into use with tubular access. This has now been adapted to the percutaneous placement of spinal instrumentation, including intervertebral spacers, rods, pedicle screws, facet screws, nucleus replacement devices, and artificial discs. New technologies involving hybrid procedures for the treatment of complex spine trauma are now on the horizon. Surgical corridors have been developed utilizing the interspinous space for X-STOP placement to treat lumbar stenosis in a minimally invasive fashion. The direct lateral retroperitoneal corridor has allowed for minimally invasive access to the anterior spine.

After the Storm: Mitigating Losses Involving High-Technology Equipment Following a Flood

By: Envista Forensics - Bruce Swales

The role that water plays in our existence is well understood. Without it, most living things will rapidly wither and die. Equally catastrophic of course, are the consequences of too much water. Not only to living things, in terms of widespread flooding, but also in terms of damage to machinery and equipment from exposure to water.

Surface-Piercing Propellers

By: Paul Kamen

The art of positioning a propeller underneath a boat hull is not a new one. Designers and naval architects have been grappling with every aspect of the propulsion-by-propeller problem for generations, and the result has been the evolution of a well known set of standard and efficient solutions

Anti-Scale Valves

By: Dr.-Ing. Dirk A. Lindenbeck

In various industries there are valve applications where the standard valves used do not function satisfactorily. When scale is formed on the moving elements of ball valves or gate valves the consequence is either blocking of the valve movement or damage to the valve seats and consequent leaking through the valves

The Value of Lubricants and Lubrication Knowledge and Skills

By: John H. Marino

For me it is fascinating that in this highly competitive global marketplace, so many American companies lack the lubricants and lubrication knowledge or skills needed to protect, let alone achieve, the greatest return on their production machinery

What is most misunderstood and costly to your operation? Lubricants and Lubrication!

By: John H. Marino

Do you know that your equipment produces a profit on a thin film called lubricant? The most important but yet the most mismanaged in 99% of all companies is lubricants and/or lubrication. That’s why, it has been reported, that 60% to 70% of all mechanical failures are due to inadequate lubricants and lubrication practices
