Demand for Interspinous Spacers Has Increased Due to Increasing Prevalence of Spinal Stenosis

 

Interspinous Spacers

Interspinous spacers are medical devices implanted between the vertebrae through a small tube the size of a dime. These devices are used to treat frontotemporal spondylosis. Frontotemporal spondylosis happens when the passageways of the spine become narrow and squeeze the nerves of the spine. Interspinous spacers are made up of titanium, a lightweight but strong metal, which is biocompatible. Spinal stenosis is a narrowing of the open spaces in the lower (lumbar) spine. The condition develops gradually with age.

Thus, with the increasing prevalence of spinal stenosis and the growing geriatric population, the demand for interspinous spacers is also increasing worldwide. Spinal stenosis is more often a degenerative condition that affects people who are typically age 60 and older. According to the U.S. Census Bureau, there were 40.3 million U.S. residents 65 years and older in the 2010 Census and more than 54 million on July 1, 2019. Moreover, according to the World Health Organization (WHO), by 2050, the world's population aged 60 years and older is expected to total 2 billion, up from 900 million in 2015.

Spinal stenosis can be caused by a number of seemingly unrelated factors. However, doctors have identified certain conditions and behaviors that increase the risk of spinal stenosis. These include age (especially young people and those with poor health histories), females (women tend to develop spinal stenosis more often than men), obesity, family history, and genetic predisposition to the disease. The symptoms can range from mild to severe pain, tingling, numbness, and other sensations that make daily living difficult.

Interspinous spacers are one of the most common treatments used for treating spinal stenosis. This procedure involves the placement of thin stainless steel or titanium plates between two vertebrae in the spine. The purpose of the interspinous spacers is to relieve pressure on the nerves and facilitate healing. In the past, metal plates were placed directly over the affected vertebrae. However, these plates can lead to a number of complications including infection and nerve damage. Moreover, the metal can interfere with the healing of the vertebrae.

Light Linear Alpha Olefins Are Produces through Oligomerization of Ethylene and by Fischer-Tropsch Synthesis

Image
  Light linear alpha olefins are commonly manufactured by two main routes: oligomerization of ethylene and by Fischer-Tropsch synthesis followed by purification. They are manufactured for a variety of reasons. One such reason is to use them as fabric and other textile applications in clothing manufacture. Various companies use ethylene trimerization process that produces only 1-hexene. In the U.S., Chevron Phillips Chemical Company, LLC, uses this process. Another commercial process, offered by a technology licensor IFP, dimerizes ethylene to high purity 1-butene. There are a wide range of applications for light linear alpha olefins . They are predominantly use in production of polyethylene, linear aldehyde, fatty acids, linear alcohols. Alpha olefins are also used in production of synthetic lubricant basestock and to make surfactants in a blend with higher linear alpha olefins. Another common use of light linear alpha olefins includes printing and apparel industries, agriculture

Cervical Cancer Diagnostic Tests have become highly sophisticated with accurate diagnosis for effective treatment

Image
  There are three basic types of cervical cancer namely squamous cell carcinoma (also known as cancer of the cervix), adenocarcinoma, and carcinoma in the fallopian tubes. Adenocarcinomas are the most common type and usually begin as a non-cancerous tissue. Squamous cell carcinomas (also called vaginal cancer of the cervix) develop primarily in the outer lining of the cervix and is normally found in 90 to 95% of cervical cancer cases. One of the key cervical cancer diagnostic tests are HPV diagnostic test and they are at an all-time high. As previously stated, research reports continue to indicate that the future is not likely to see a slowing of the rate of new infections, but instead an acceleration into the future. The Information presented in this article briefly outlines two of the most important players in the cervical cancer diagnostic tests sales, price and growth rate of HPV. A recent development in DNA cervical cancer diagnostic tests makes it possible to determine if a pe

Beta Glucan-based products have been shown to be effective in lowering cholesterol and preventing heart disease

Image
  Beta glucan based products have been being used for the most recent decade. These are significant leap forwards in present day clinical history. Beta glucan is gotten from plant sources and has been utilized for quite a long time to assist wellbeing. It is nothing unexpected that this compound has as of late discovered its way into the nourishing enhancements field. It is perhaps the most nutritious enhancements available. Exploration has shown that individuals who burn-through Glucan based products have lower paces of coronary illness. It is accepted that the part of the enhancement helps support the insusceptible framework and expands the body's resilience to low degrees of cholesterol. This permits the body to all the more proficiently eliminate overabundance cholesterol from the circulatory system. Besides, the fixings in these products are high in cancer prevention agents, which help forestall cell harm. Studies have shown that Glucan products can help diminish joint irrit
