The human body endures a great deal of wear and injury during its lifetime. It is for this reason that the body has several tissues that are capable of regeneration. Bone is one of those tissues that receives extensive use so it is necessary that it is strong in order to carry out its functions; however, it will occasionally face injury. Although our bones are capable of regeneration, a new method would help the elderly and others that have a more difficult time healing after injury. I viewed a “TED Talk” lecture, which discussed a new way of regenerating bone with the help of our own bodies. Molly Stevens, the head of a biomaterials lab, presented “A New Way to Grow Bone” where she discussed a new technique called “in vivo bioreactor”. She also answered why this new procedure is beneficial. Researchers like Stevens are constantly trying to find innovative new techniques and they do this by asking questions. The question that Stevens presented in the video was an intriguing one: “Can we recreate the regeneration of bone on demand and transplant it?”. …show more content…
The medical community currently harvests grafts from the iliac crest as it is strong and vascularized. It’s also beneficial to harvest bone from the same body that will be receiving the graft. Despite the benefits, this procedure is painful and can introduce chronic pain in that area. Although this might be an effective method, I believe that there ought to be a better way to do these grafts. Walking is a part of our everyday life and to take bone from the pelvic area would halt that ability for some
...ograft. If the graft comes from someone who has died, it is called an allograft. Doctors have tried using some types of synthetic grafts but so far these have not worked well. Research is being done to see if there are better types of grafts that can be used.
Metal-on-metal hip resurfacing improves health related quality of life (1), post-operative function (2-5) and activity (6). Increasing number of hip resurfacing arthroplasties is being undertaken with good to excellent outcomes (4). Published reports show significant advantages of hip resurfacing as compared to total hip arthroplasty. Studies have shown improved gait parameters (7) and increased range of motion (8), but others have reported no difference when compared with standard hip arthroplasty (9, 10).
With ABC recipient site classification surgeons gain some insight in to regenerative potential of the surgical bed and can consider some modifications to help increasing of success rate of bone healing and decreasing morbidities of donor sites.
The novel “Salvage the Bones” started with the bible verse “See now that I, even I am he, and there is no god with me; I will kill and I make alive, I wound and I heal, neither is there any can deliver out of my hand.” As the novel started with this verse, readers could expect to see a lot of painful experiences that involve life, death and painful events in the characters in the novel. The theme of loss and tragedy is one of the prominent themes that is being portrayed in this novel. The two characters that are affected badly by the theme of loss are Esch and Skeetah. Esch losing the love of her life: Manny, while Skeetah losing his precious dog, China. Through the loss and tragedy event, the readers could see how the characters develop and
Reconstruction using donor tissues will have two surgical sites and scars. Recovery takes a bit longer. But, they look more natural than implants. There is also no worries about implant ruptures or the need for future
Skin grafting is a taking skin from a healthy part of the body, and transplanting it onto another part of the body that has been severely damaged, for example, a third degree burn. The grafting serves two purposes: firstly, to reduce the course of treatment needed (including time spent at the hospital), and secondly, to improve the function and appearance of the area of the body which will receive skin grafting.
Bone tissue engineering (BTE) plays an important role in treating bone diseases related to osteoporosis and other orthopedic treatments. Although several methods are used in orthopedic surgery, some bone transport methods such as autografting and allografting have a certain number of disadvantages. Both are expensive methods and they can be exposed to infections and diseases. Therefore, in stead of using these potential risky methods, bone tissue engineering process are used to treat in orthopedic treatments. In general, both tissue engineering and bone tissue engineering have major constituents including stem cells, scaffold, bioreactors and growth factors.
Total Hip Replacement (THR) is a surgical procedure that relieves pain from most kinds of hip arthritis, thus helping to improve the quality of life for the majority of the patients that undergo the operation. Arthritis simply means "inflammation of a joint." Arthritis can occur in any joint in the body. The main symptom of arthritis is pain which usually worsens with activity and weight bearing. This pain may be relieved most of the time through rest. There are over 100 types of arthritis but less than a handful account for over than 95 percent of the hip replacements that are performed. Some of these include Osteoarthritis (causes deterioration of the cartilage and the growth of bone spurs), Rheumatoid arthritis and Osteonecrosis of the femoral head. Doctors suggest that before considering hip replacement surgery for arthritis that the patient tries a number of non-operative interventions. Your doctor may have you consider little things such as weight loss (most arthritis is caused due to the weight bearing on a joint), activity modification or even the use of a cane. Patients should consider THR when daily living activities become harder to accomplish due to the pain. These activities would include walking, climbing stairs or other moderate pastimes. Anti-inflammatory medications which will help reduce the inflammation from the arthritis and reduce your pain may also be prescribed by the patient's doctor.
An allograft is either bone, cartilage, tissue, ligament, tendon or any section of the skin that is donated from another person that is deceased. Allografts do contain osteoconductive scaffolds with minimal osteoinductive factors. A disadvantage of Allografts is the risk of bacterial contamination or the possibility of viral transmission diseases such as hepatitis and human immunodeficiency5. Jorgenson et al.6 Conducted a prospective analysis in lumbar fusion of allografts versus autografts in the same patient and concluded that an ethylene oxide-treated allograft is inferior to an autograft and should not be used for posterior lumbar fusions(Level II). Further, An et al.7conducted a prospective comparison of autografts and allografts for adult posterolateral lumbar spinal fusion and reported that autografts resulted in significantly greater bone density, followed by the mixture of autografts and allografts, frozen allografts, and freeze-dried allografts (Level II). These reports indicate that allografts alone were not able to achieve a sufficient fusion rate for posterior spinal fusion in the adult
Limb attachments are not uncommon. Dr V Pathmanathan and his team, who transplanted a left arm onto baby Chong Lih Ying from her twin sister who had died at birth, had already performed over 300 such operations (2). The controversy occurs when the limb is not simply reattached, but is transplanted from one person to another. This is because limb transplant patients, like any other transplant patients, need to be given anti-rejection medication, immunosuppressive therapy (1), so that the body's immune system does not recognize the new limb's tissue as foreign and destroy it (3). In fact, Chong Lih Ying was the only limb transplant patient not to receive immunosuppressive drugs. Because her arm was transplanted from her twin, there was very little risk of rejection (2).
By definition, "osteoporosis, or porous bone, is a disease characterized by low bone mass and structural deterioration of bone tissue, leading to bone fragility and an increased risk of fractures of the hip, spine, and wrist" (National Institute of Health- Osteoporosis and Related Bone Diseases, 2012). Both Berarducci (2008) and Hansberger’s (2005) article note that osteoporosis is the most common disease of all bone disorders, affecting both men and women. The incidence of the disease is growing in the United States with almost 44 million affected Americans and an estimate incidence rate of 10 to 14 million by 2020. Deemed a "silent" epidemic, there is a low level of diagnosis, and even lower level of treatment. Walker (2010) supports Hansberger (2005) that the disease causes pain, depression, anxiety, loss of mobility, and ultimately fractures. It is crucial that Advanced Practice Nurses/Nurse Practitioners have a solid understanding of the disease and are able to identify risk factors, order the proper diagnostic testing, and treat their patients.
In time, the jawbone may severely deteriorate to the point where there will not be enough bone for dental implants to be placed. That’s where bone grafting comes in. Bone grafting is a minor surgical procedure that is intended to build up new bone in the jaw area that is used to hold the teeth. This procedure prepares patients for future dental implants.
A regenerative medicine is the new treatment for patients that has severe reproductive system disease. In the past few years scientist has develop an advance way to restore reproductive tissue engineering in order to restore the normal sexual function in both male and female. The advances include the use of the cells, tissue, and organs regenerative medicine approach for clinical submission to treat reproductive system disorders.
The field of regenerative medicine encompasses numerous strategies, including the use of materials and de novo generated cells, as well as various combinations thereof, to take the place of missing tissue, effectively replacing it both structurally and functionally, or to contribute to tissue healing[29]
