Extractions: I assume this is a lumbar (low back) problem. My understanding on this topic is limited to my personal experience as a 38 year old with a herniated (medical for ruptured) low lumbar disk requiring surgery last year. Traction is not used much. If oral antiinflammatories aren't helping, you may need to ask about 1. Oral steroids. 2. Epidural steroid injection. Good luck Garry *Note: Opinions expressed here are for educational purpose only.

Extractions: Corrosion, Failure Analysis and Materials Selection Specialists Corrosion Testing Failure Analysis Return to Failure Analysis Case Histories Failure Analysis of Corroded Rupture Disc ENVIRONMENT: Sulfuric Acid EQUIPMENT: Process Equipment MATERIAL: Alloy C-276 FAILURE: Corrosion Background The company manufactures equipment that is used in the processing of silicon wafers. Part of the process involves the use of hot ozonated sulfuric acid. Since the system is under slight pressure, a rupture disc is used to protect the equipment from excessive pressures. The rupture disc is constructed of Alloy C-276 with a thin layer of Teflon FEP applied. A skived film of PTFE is placed over the process side of the disc to protect it from the environment and serve as the joint seal. The PTFE film is scored along the outer edge of the rupture disk to facilitate failure of the film upon rupturing of the disc. Three exposed discs that had become discolored were submitted for analysis. A failure analysis was requested to determine if the discoloration was due to corrosion and if so, the cause. FINDINGS Visual Examination and Wet Sponge Test All three ruptured disc assemblies were photographed in the as-received condition. The metal discs appeared intact with no visible deformation except for the manufactured dimple at the center of the disk.

Two different surgical approaches are used depending on the location of the pathology and clinical situation: (1) Posterior, and (2) Posterolateral. Posterior endoscopic discectomy is the first approach, which is performed with a small skin incision made at the midline posterior lumbar region. A small trocar is inserted towards the herniated disc. The herniated disc material is removed under the direct endoscopic visualization. The disc located between the spinal bone is preserved as much as possible in order to maintain the spinal integrity.
Extractions: Cervical disk protusions, if they compress the nerves in the neck typically cause arm pain . There are a number of operative ways that this can be managed but, if suitable, a posterior cervical foraminotomy is a vastly under-rated operation which avoids some of the shortcomings of other disk operations and yet still has an excellent outcome in terms of symptom relief, in a minimally invasive fashion. The typical patient presents with pain down one arm which may radiate to the hand . Cervical disc problems are exceedingly common and it is important to realise that in the vast majority of cases non-operative management works very well. Most patients settle within 6-12 weeks after the onset of symptoms. The pathophysiology of why a patient gets symptoms is disc protusion is complex, as not all disk patients get pain. A posterior cervical foraminotomy is a minimally-invasive procedure designed to enlarge to space through which the nerve root exits from the spinal cord (the so-called neural foramen) and at the same time try to remove any piece of disk which is pushing on the nerve. Interestingly, sometimes the foraminotomy alone can alleviate symptoms without a diskectomy being needed. The whole disk is not removed, just the fragment pressing the nerve root. A fusion is not performed and most patients typically do not require a neck collar after the surgery.

Key points are important factors in any given medical decision. In this case, you need to know that: Herniated disc surgery offers the most benefit and relief for people with severe sciatica caused by a herniated disc. There is currently a lack of scientific evidence that points to the best timing of herniated disc surgery. People who have herniated disc surgery usually have better pain relief over a 4-year period than people who don't have surgery. However, these early benefits may decrease over time.

Extractions: Rupture disks and other pressure relieving devices must be of an adequate size if they are to prevent system overpressure. The conditions for which over-pressure protection may be required must be carefully considered. During relief operations, the maximum flow rates necessary to prevent a pressure increase beyond specified limits must be determined. The ASME Code requires that when a rupture disk is used as the primary relief device, it must be sized to prevent the pressure from rising above 110% of the MAWP (UG-125(c)). If used as a secondary relief device or as multiple relief devices, the size must prevent the pressure from rising above 116% of the MAWP (UG-125(c)(1)). If used as a supplementary relief device for hazards external to the protected vessel or system, the size must prevent the pressure from rising above 121% of the MAWP (UG-125(c)(2)).

Not all CO2 cylinders on the market today contain a unified burst disk. Various cylinders in the industry contain three separate pieces: a plug, a rupture disk and a retaining ring. This style of burst disk allows a user the ability to tamper with the rupture disk or to replace the rupture disk with an undisclosed amount on foreign material. It is also possible for a user to purposely or accidentally replace a ruptured disk with two or more replacement burst disks. Either situation will result in a serious safety hazard to the user and to others in the vicinity.

Back pain caused by overexertiona form of injuryis also very common. About 60 percent of industrial back injuries result from overexertion, usually in the form of strains or sprains. Emotional stress can also bring on tension, which in turn tightens muscles and cause discomfort. Then, too, there are those cases where you and the healthcare professionals just can't determine exactly where the pain comes from . . . I know what your thinking. But, Dr. Chiu, you said that there is hope for all back-pain sufferers. Well, the statement in the last paragraph doesn't change anything. Even those cases where we can't determine exactly what the problem isand those are becoming rarecan be helped through a proper back-care program.

Low Back Pain Backpaingo.com The most frequent cause of this condition is a ruptured disc in the lower back. This condition has been called herniated disc, ruptured disc, http://www.backpaingo.com/LowBackPain.html
Extractions: 1-877-BACK-552 VARIOUS FORMS OF LOW BACK PAIN Back pain refers to pain any where from the area of the neck to the tailbone. The back includes the bones of the spine ( vertebrae ), the joints that guide the direction of the movement of the spine, the discs that separate the vertebrae and absorb shock as a person moves, and the muscles and ligaments that hold them all together. Back pain may be caused by an injury to one or more of these structures, or it may have nothing to do with an injury. For our purposes we will deal only with the lower or lumbar area. Herniated Disc . Many times this is called a ruptured or bulging disc . Herniated discs are caused by aging or degeneration of the disc ( degenerative disc disease ) or injury to the spine. Disc disease may result from tiny tears or cracks in the outer shell(capsule) of the disc. The jellylike material inside the disc (nucleus) may be forced out through the tears or cracks in the capsule. This causes the disk to bulge ,break open (rupture), or break into fragments.

Extractions: Lumbar discs are the structures which serve as shock absorbers between the vertebrae of the spinal column. The center of the disc, called the nucleus, is soft and springy and accepts the shock of standing, walking, running, etc. The outer ring of the disc, called the annulus, provides structure and strength to the disc. The annulus is comprised of a complex series of interwoven layers of fibrous tissues which hold the nucleus in place. What is a Herniated Disc Herniated discs are often called a "slipped disk". This term was derived from the action of the nuclear tissue when it is forced from the center of the disc. The disc itself does not slip. However, the nuclear tissue located in the center of the disc can be placed under so much pressure that it can cause the annulus to herniate or rupture. When the disc has herniated or ruptured, it may create pressure against one or more of the spinal nerves which can cause pain, weakness or numbness in the lower back, leg or foot (sciatica). Other common names for a herniated disc are "protruded disk" and "

Cervical Disc Disease This occurs when there is a moderate disc rupture (see Fig. 2). This prevents recurrence of any disc rupture, while allowing normal motion and pain free http://www.petsurgery.com/cervicaldiscdisease.html
Extractions: Cervical Disc Disease Intervertebral disc disease is the most common neurologic syndrome seen in dogs. Disc degeneration has been reported in 84 breeds with particular susceptibility in certain small breeds. These breeds (Dachshund, Pekinese, Poodle, Beagle, etc.) have characteristic skeletal changes that predispose the discs to degenerate at a very early age. Intervertebral discs act as cushions between the vertebrae and function as the shock absorbers of the spine. A normal disc has two regions: a resilient gelatinous nucleus (center) and an outer fibrous ring that encircles the nucleus (see Fig.1). A degenerative disc loses its resiliency when its jelly-like center calcifies and develops a gritty, hardened consistency. No longer able to cushion the vertebrae, the center is predisposed to bulging and to rupture (extrusion), resulting in pressure on the spinal cord, pain, and paralysis. Cervical (neck) lesions account for approximately one fifth of all intervertebral disc problems. Most patients experience neck pain as the first and most consistent clinical sign. This occurs when there is a moderate disc rupture (see Fig. 2). The head and neck are held in a tense position with the patient reluctant to elevate the head and neck when climbing stairs or to eat or drink. The neck often appears swollen or thickened when muscle spasms become intense. Spontaneous whining with cervical guarding, evident by periodic elevations of the ears and muscle spasms, are often seen. One sided disc ruptures (see Fig. 3) can result in lameness of one front leg. When discs rupture in the center of the spinal canal, both front and rear limbs become weak. This can progress to paralysis of all four limbs (see Fig. 4).
