Introduction Osteoarthritis (OA) is the most common form of arthritis affecting at least 20 million Americans with its prevalence expected to double in the next 2 decades (12.) (9). OA was once believed to be a consequence of aging, which still holds true, but is now believed to involve a multitude of biological and pathological processes influenced by several factors, including genetics, age, gender, obesity, joint injury, estrogen, diabetes and muscle strength with age and weight being the predominating factors. OA is a multifactorial disease that may progressively affect the structure of all joint tissue leading to joint pain and inflammation. The pathogenesis of OA has yet to be clearly defined but is is characterized by progressive hyaline …show more content…

OA also can effect the personal and social life, socioeconomic status, and psychological well being of people inflicted with this disease (13).
Osteoarthritis is usually treated with analgesics and non-steroidal anti inflammatory drugs. These drugs have been shown to cause serious gastrointestinal and cardiovascular adverse events, especially with long term use (17) Other medical interventions including orthopedic surgery such as joint replacement have been implemented with OA Patients. There have been several studies on the the use of glucosamine and chondroitin with the treatment for the treatment and prevention of OA. Glucosamine and chondroitin are among the most popular non-vitamin, non-mineral specialty supplements in the United States, with sales of the supplements reaching over 2billion dollars globally (7) (17) They are often taken together as a single daily supplement for osteoarthritis. It has been estimated that 7.4% of older Americans use glucosamine-chondroitin, a prevalence of use similar to that for acetaminophen. While the biologic effects of these …show more content…

(2007). conducted a randomized, double-blind, placebo-controlled, cross-over study to assess the effects of glucosamine hydrochloride (1500 mg/d) plus chondroitin sulfate (1200 mg/d) for 28 days compared to placebo in 18 healthy, overweight adults, aged 20–55 y. Statistically significantly lower geometric mean CRP concentrations were observed after the G&C intervention compared to placebo (-23%, P = 0.048). No significant differences were observed in the other inflammation or oxidative stress biomarkers assessed, although they were slightly lower after G&C supplementation with the exception of the soluble TNF receptors, which increased by 1–3%.

    “The doctor of the future will give no medication, but will interest his patients in the care of the human frame, diet and in the cause and prevention of disease” by Thomas A. Edison. Chiropractors use hands-on spinal manipulation and other alternative treatments on the spine which will enable the body to heal itself without surgery or medication. Chiropractic care began in 1895 when its founder, Daniel David Palmer, claimed any and all diseases could be healed by nothing more than just his hands. Dr. Palmer examined a janitor who was deaf for 17 years after the janitor felt his back was out of place, so Dr. Palmer gave an adjustment to what was felt to be a misplaced vertebra in the upper back. The janitor then observed that his hearing improved thanks to Dr. Palmer. Chiropractors use manipulation to restore mobility to joints restricted by tissue injury caused by sitting without proper back support. Chiropractic is primarily used as a pain relief alternative for muscles, joints, bones, and connective tissue, such as cartilage, ligaments, and tendons. About 22 million Americans visit chiropractors annually

    “The purpose of a doctor or any human in general should not be to simply delay the death of a patient, but to increase the person’s quality of life.” Orthopedic surgeons treat a number of conditions that affect the bones, joints, muscles, tendons, and nerves. The training to become an orthopedic surgeon requires multiple years of hard work and studying, but in the end, the success is worth all the stress and struggle experienced on the way. Most doctors must dedicate every fiber of their being, countless hours of work, and years of stress in their chosen profession. Medicine is only for those who can’t imagine doing anything else.

  • Osteoporosis Essay

    Osteoarthritis is a degenerative joint condition that primarily affects the hands, spine and the ankles and hips. It is known to be associated with aging, and is concerned with the cartilage that protects the joints (the meeting place of two bones). Normal cartilage allows for bones to slide over each other uniformly, acting as a shock absorber to any damage. However cartilage in osteoarthritis, located at the ends of the bones erodes and deteriorates, causing friction and hence pain, swelling and restricted movement. Therefore in osteoarthritic both the composition and appearance of the cartilage alters, while the body attempts to repair this damaged cartilage is broken down faster than it can be built up. A defective repair process can cause bone overgrowth, bone spur/osteocytes to form which can be seen at the ends of the joints. In osteoarthritis the bones come in close contact with each other, and wear away leaving the bone exposed and unprotected.

    Osteoarthritis (OA) is the most common form of arthritis, affecting more than 27 million Americans (LeMone, Burke, Bauldoff, 2011). It is caused when the cartilage in the joints breaks down, causing the bones of the joint to rub against one another. This causes pain, stiffness, and loss of motion in the joint. Osteoarthritis is most prevalent in those 65 and older, but can affect those of any age. In addition, African Americans and Hispanics report a higher incidence of arthritis than Caucasians (LeMone, Burke, Bauldoff, 2011). Although the cause is unknown, it is believed that the increasing age of the population, prevalence of obesity and injuries add to the progression of the condition. Osteoarthritis can affect any joint in the body; however, those of the hand, hip, and knee are often the most common. This condition may be asymptomatic, or may present symptoms including soreness, stiffness and pain. The symptoms are more common in the older population, those with limited activity levels, and those who are obese. Joint cartilage thins over time, causing an increased risk for symptoms in the elderly, and obesity puts extra pressure on the joints during activity. Osteoarthritis is commonly diagnosed with the use of a physical assessment along with results of radiology testing such as X-Ray and MRI.

  • Overview of Osteoarthritis

    OA is a musculoskeletal disease that causes chronic joint pain and reduced physical functioning (Laba, brien, Fransen, & jan, 2013). Osteoarthritis (OA) is a non-inflammatory disorder of synovial joints that results in loss of hyaline cartilage and remodeling of surrounding bone. OA is the single most common joint disease, with an estimated prevalence of 60% in men and 70% in women later in life after the age of 65 years, affecting an estimated 40 million people in the United States (Goodman & Fuller, 2009). Women are more commonly affected after the age of 55, almost everyone has some symptoms by the age of 70 (Tan, Zahara, Colburn & Hawkins, 2013, p.78). Osteoarthritis can be described radiological, clinical, or subjective. It commonly affects hands, hips, knees, shoulders, and the spine (Walker, 2011, p. 14). Osteoarthritis is an intrinsic defect in the joint cartilage. Caused by slowly progressive deterioration of articular cartilage that is accompanied by degenerative bony changes, including thickening of the subchondral bone cyst, and formation of large bony protrusions (osteophytes) at the joint margins. Osteoarthritis usually occurs in the large weight bearing joints such as the knees and hips, as well as some of the smaller joints in the hands and feet (Ciccone, 2007,p. 229). ). It is predicted by 2020 to become the fourth leading cause of disability globally (Laba et al., 2013, p.2). According to Juby and Davis (2011), these changing demographics with the aging of the “baby boomer” generation will likely result in an increase in the prevalence of both degenerative and inflammatory arthritis, and timely access to appropriate care and maximization of therapeutic interventions will be vital to maintain indepe...

  • Osteoarthritis And Rheumatoid Arthritis

    1793 Words  | 4 Pages

    Arthritis affects people of all age groups. More than 100 types of arthritis are known. Among these osteoarthritis and rheumatoid arthritis having the highest incidence. One of the major causes of chronic debilitation in industrialized nations is Osteoarthritis which results from damage to the joints, which may be due to trauma, infection, or age-related wear. Rheumatoid arthritis is encountered less frequently than osteoarthritis and is estimated to affect around one per cent of the world’s population. Amongst patients of Rheumatoid arthritis, women are three times more likely to be affected by this condition than men. This condition is caused by an inflammatory process where the body starts attacking itself. Rheumatoid arthritis also affects several joints, with inflammation sometimes seen in and around the lungs, the heart, the eyes and the skin. The most commonly reported complaint by arthritis patients is pain. The pain might be from the joint itself and be a result of inflammation, damage from the disease, or through daily wear and tear. Muscle pain is also common and is caused by having to force movements against stiff and painful joints. Although range of movement in the affected joint may be limited and uncomfortable, physical exercise has been shown to benefit those with arthritis. Physical therapy has been shown to significantly improve function, decrease pain in the long term and delay the need for surgery in advanced cases. The majority of arthritis cases occur among theelderly, however the disease can occur in children as well. Over 70% of the population that get affected by arthritis in North America are over the age of 65 (4). The disease occurs more commonly in females than males in all races, age groups, and ethn...

    Almost everyone develops osteoarthrits as they age, some get it while in their fifties and in others it does not appear until their eighties. Osteoarthritis is the most common form that affects older people; this form of the disease wears down the cartilage mostly through overuse and injury but there are other causes. This specific form of the disease causes the cartilage to break down and the bones to rub against each other. Deformity and swelling occurs because knobs of hardened bits of cartilage develop in the joint. It forms especially if a joint has been injured many times.
