Prosthesis is a process through which lost body parts are replaced using artificially modified parts. The loss of these body parts may have occurred through accidents trauma, diseases or other congenital conditions that may have taken place in the life of an individual. The word comes from the Greek word prosthesis which refers to application or addition. Different types of prosthetics are designed since people have different needs of the same. For example a particular patient may require transradial prosthesis but will be required to choose between one that is aesthetic functional, myoelectric, body powered or one that is specific to a given activity.
This article explains into details the categories of prosthetics and in this case craniofacial prostheses is said to include both intra oral and the extra oral prosthetics. The extra oral type is further classified into auricular, hemi facial, nasal, ocular and orbital. The other type, that is, intra oral includes the dental implants and obturators. It also states that scientists have come up with all body parts prosthetics and this is a major advancement in the world of health. They have been a major improvement to the patients as they do not have to worry so much about not having some body parts as they are artificially available.
There are prosthetics of the most complicated parts of the body for example the esophagus and the larynx. When women have breast cancer and it leads to amputations, they need not to worry anymore since breast prosthetics are available. This is an advancement that has taken the energy of most of the scientists through doing some of the researches and developments. It has been a breakthrough in coming up with these developments.
At the start of these developments, limb prosthetics were seen to be less energetic as compared to other prosthetics. According to Oscar a double amputee, he said that the important part to consider when creating the prosthetics is the material and the need of the patient. After developing the arm titanium link to the bone, scientists found out that the arm was strong enough that even patients could walk on them.
The next development that followed this was the creation of a strong limb that could be supportive enough for the patient to participate in the games that took place in their communities. It did not take long for the world to know that the prosthetics were strong after a runner who had his two limbs as prosthetics finished first in a race. The limb prosthetic was developed by the Stanmore implants and they call their device the Intraosseous transcutaneous amputation prosthesis (ITAP).
The inspiration to do this project was acquired from a paper that was published in the Journal of Anatomy and it happened to call for the attention of the researchers. It was referred to as the “natures answer to breaching the skin barrier” and describes the methods used by mammals to adopt to harsh conditions. Through dissecting the bone of a deer, they were able to find out that the thighs had highly porous networks of the bone so that its muscles are highly tied to them making them strong enough and this makes it possible for them to run fast and tirelessly and with a lot of stability. This makes them not to suffer from bacterial infections and they therefore can succumb to very tough conditions.
Through such a discovery, they were able to develop a titanium link to bones which enabled the amputations to remain strong and helpful to those who have them. They are coated in order to ensure that they do not have negative effects on the patients. Stanmore implants are mostly used as internal fixations of bones due to cancerous infections and serious diseases. Their contact is maintained through magnetism forces in between the metallic joints of the amputated parts of the body. The Stanmore implants went ahead to discover a bone elongation method that enables one to develop a growth in bones which means that they do not have to undergo amputations in case they suffer from loss and injuries that may call for the use of prosthetics.
The inventions have continued through the years and it seems that we should expect more in the world of medicine since many other discoveries are yet to come. Though these prosthetics are approved, they are also associated with negative effects such as problems in the circulation system, injuries associated with trauma for example due to traffic accidents and combats in the military. Cancers also may occur in case prosthetics lack the necessary coating thus necessitating development of unwanted materials in the body. Ladies with internal prosthetics may also suffer from birth defects. Besides these negative effects, prosthetics are seen to be important and a life saver for many and this is supported by the large number of individuals who have them in their bodies.
Many people have enjoyed their service and do not complain of negative effects since they are able to perform their daily activities easily and with no hindrances. In that case prosthetics are approved by the health ministries and countries as well.
