Well designed prosthetics deliver both functionality and are cosmetically pleasing, but it also serves to complete the amputee&#;s sense of wholeness. Prosthetics that are well-designed and functionally pleasing to the eye not only enhance amputees&#; sense of wholeness, but also add beauty to their lives. A prosthesis provides mobility as well as emotional comfort, and so the history of prosthetics is not only a scientific history, but the story of human beings since the dawn of civilization who by birth, wound, or accident were left with a missing limb. Prosthetics provide mobility and emotional comfort. This is why the history of prosthetics goes beyond science to tell the story of humans since the dawns of civilization, when people were left without limbs due to injury, birth, or simply because they didn&#;t know what to do.
The earliest example of a prosthesis ever discovered is not a leg, arm, or even a fake eye, it&#;s a toe. It&#;s not a leg, arm or fake eye that was the first prosthesis to be discovered. A big toe, belonging to a noblewoman, was found in Egypt and dated to between 950-710 B.C.E. This large toe belonged to a noblewoman and was discovered in Egypt. It dates back to between 950-710 B.C.E. We all know that toes are important, but it&#;s interesting that our earliest physical example of the history of prosthetics is a toe and not something that might seem more important, like a leg or an arm. While we all know toes are very important, it is interesting to note that the earliest example of prosthetics in human history was a toe. This was not a leg or arm. The big toe was particularly important to an Egyptian because it was necessary in order to wear the traditional Egyptian sandals. Because the big toe was required to wear traditional Egyptian sandals, it was especially important for an Egyptian. Worn nearly 3,000 years ago, this toe is a representation of the history of prosthetics being as much about function as identity. This toe, which was worn nearly 3,000 years ago is a symbol of how prosthetics have been used for function and identity throughout history.
To show how little prosthetic limbs have advanced through most of history, consider the artificial hands and legs of the Dark Ages &#; nearly 2,000 years later.|Consider the artificial hands and legs that were used in the Dark Ages nearly 2,000 years ago to show how far prosthetic limbs have come. Armored knights of this era often relied on iron prosthetic limbs, usually crafted by the same metalworker who made their armor. Iron prosthetic limbs were often used by armored knights in this period. They were usually made by the same metalworker as their armor. These bulky limbs were admittedly not very functional and were actually used more for the purpose of hiding the lost limb, which was considered at the time to be an embarrassing deformity. Although these limbs were not functional, they were used to conceal the missing limb.
Most famously attributed to seafaring pirates, peglegs with wooden cores and metal hands shaped into hooks have actually been the prosthetic standard throughout much of history.The most famous use of peglegs by seafaring pirates is to make hooks out of metal hands and wooden cores. While Hollywood has exaggerated their use of hooks and peglegs, pirates did sometimes rely on these types of prostheses. Although Hollywood exaggerated the use of hooks or peglegs by pirates, they did occasionally rely on these prostheses. The required materials for these devices could be scavenged from a common pirate ship; however, a trained doctor would have been rare. Although the materials needed for these devices can be found on any pirate ship, it is rare to find a trained doctor. Instead, the ship&#;s cook typically performed amputation surgeries, albeit with poor success rates. The ship&#;s cook performed amputations, but with low success rates.
Ambroise Pare: Father of the Modern Prosthetic Leg
Ambroise Pare was an accomplished barber/surgeon and anatomist who was the official royal surgeon for four French kings. Ambroise Pare, a skilled surgeon/barber and anatomist, was the official royal physician for four French kings. He is regarded by many as the father of modern surgery. Many consider him the father of modern medicine.
Along with improving amputation techniques and survival rates during his time as a war surgeon, he developed functional prosthetic limbs for all parts of the body. He also improved amputation techniques and survival rates while serving as a war surgeon. Additionally, he created functional prosthetic limbs that could be used for any part of the body. He used his understanding of anatomy to design prosthetics that mimic the function of biological limbs. His anatomy knowledge was used to create prosthetics that replicate the functions of biological limbs.
He was the first to develop an above-knee prosthetic with an adjustable harness and a hinge-knee with lock control &#; both of which are still used today. He was also the first to create an above-knee prosthetic that included an adjustable harness and a hinge knee with lock control. Both of these are still in use today. He also transitioned away from wood in favor of much lighter prosthetics made of leather, paper, and glue. He also switched from wood to lighter prosthetics made from leather, paper, glue.
Around , a Dutch surgeon, Pieter Verduyn, later developed a lower leg prosthesis with specialized hinges and a leather cuff for improved attachment to the body. Pieter Verduyn (a Dutch surgeon) developed a lower leg prosthesis around . It featured specialized hinges and a leather band for better attachment to the body. Amazingly, many of the advances contributed by these two doctors are still common features of modern day prosthetic devices. Surprisingly, many of these advances are still present in modern prosthetic devices.
Londoner James Potts invented an above-knee prosthetic in with a calf and thigh socket made of wood, and a flexible foot attached with catgut tendons to a steel knee joint. James Potts, a Londoner, invented an above-the-knee prosthetic that was made from wood and had a calf socket and thigh socket. A flexible foot was attached to the steel knee joint with catgut tendon. This design was not only more articulate than precious prosthetics but was considered more aesthetically pleasing. This design was more expressive than other precious prosthetics and was more aesthetic.
This design emigrated to the U.S. in and was the standard leading up to the U.S. Civil War. This design was adopted by the U.S. Civil War in .
With the advent of gaseous anesthesia in the s, doctors could perform longer, more meticulous amputation surgeries, allowing them to operate on the limb stump in such a way as to prepare it for interfacing with a prosthesis. Gaseous anesthesia was introduced in s. This allowed doctors to perform more detailed amputation surgeries. Advances in sterile, germ free surgeries also improved the success rate of amputation procedures, increasing the need for prosthetic limbs. The success rate of amputations has increased due to advances in sterilization and germ-free surgery.
As artificial limbs became more common, advances in areas such as joint technology and suction-based attachment methods continued to advance the field of prosthetics. As artificial limbs became more common advances in joint technology and suction based attachment methods continue to propel the field of prosthetics. Notably, in , a prosthetic arm was developed that could be controlled by the opposite shoulder with connecting straps &#; somewhat similar to how brakes are controlled on a bike.In , a prosthetic arm that could be controlled from the opposite shoulder using connecting straps was created &#; similar to how brakes work on a bicycle.
The National Academy of Sciences, an American governmental agency, established the Artificial Limb Program in .|In , the Artificial Limb Program was established by the National Academy of Sciences. This American government agency is called the American Government Agency. The program was created in response to the influx of World War II veteran amputees and for the purpose of advancing scientific progress in artificial limb development. This program was established in response to the increasing number of World War II amputees. It also aims to advance scientific research in artificial limb development. Since this time, advances in areas such as materials, computer design methods and surgical techniques have helped prosthetic limbs to become increasingly lifelike and functional. Prosthetic limbs have become more functional and lifelike thanks to advances in materials, surgical techniques, and computer design.
Modern Prosthetics
The World Wars necessitated new advancements in prosthetic technology.|New advancements in prosthetic technology were required after the World Wars.
After World War I, the Surgeon General of the U.S. Army got the ball rolling on what would become the American Prosthetics and Orthotics Association. The American Prosthetics and Orthotics Association was established by the Surgeon General, U.S. Army, after World War I. Despite this, there were no major advancements in prosthetics till post-World War II when the U.S. government provided funding to military companies to improve the form and function of prosthetics. Despite all this, prosthetics did not see any major advances until post-World War II, when the U.S. government funded military companies to improve their form and function. This led to many of the modern materials used in prosthetics such as plastic, aluminum, and other composite materials. Many of the current materials in prosthetics, such as aluminum and plastic, were made possible by this funding.
Also noteworthy was the invention of the suction sock for above-knee prosthetics at UC Berkeley in . Notable was also the invention by UC Berkeley of the suction sock to support above-the-knee prosthetics.

prosthesis, artificial substitute for a missing part of the body. The artificial parts that are most commonly thought of as prostheses are those that replace lost arms and legs, but bone, artery, and heart valve replacements are common (see artificial organ), and artificial eyes and teeth are also correctly termed prostheses. The term is sometimes extended to cover such things as eyeglasses and hearing aids, which improve the functioning of a part. The medical specialty that deals with prostheses is called prosthetics. The origin of prosthetics as a science is attributed to the 16th-century French surgeon Ambroise Paré. Later workers developed upper-extremity replacements, including metal hands made either in one piece or with movable parts. The solid metal hand of the 16th and 17th centuries later gave way in great measure to a single hook or a leather-covered, nonfunctioning hand attached to the forearm by a leather or wooden shell. Improvement in the design of prostheses and increased acceptance of their use have accompanied major wars. New lightweight materials and better mechanical joints were introduced after World Wars I and II.

See all videos for this articleOne type of below-knee prosthesis is made from plastic and fits the below-knee stump with total contact. It is held on either by means of a strap that passes above the kneecap or by means of rigid metal knee hinges attached to a leather thigh corset. Weight bearing is accomplished by pressure of the prosthesis against the tendon that extends from the kneecap to the lower legbone. In addition, a foot piece is commonly used that consists of a solid foot and ankle with layers of rubber in the heel to give a cushioning effect.

See all videos for this articleThere are two main types of above-knee prostheses: (1) the prosthesis held on by means of a belt around the pelvis or suspended from the shoulder by straps and (2) the prosthesis kept in contact with the leg stump by suction, the belt and shoulder straps being eliminated.
The more complicated prosthesis used in cases of amputation through the hip joint or half of the pelvis usually consists of a plastic socket, in which the person virtually sits; a mechanical hip joint of metal; and a leather, plastic, or wooden thigh piece with the mechanical knee, shin portion, and foot as described above.
A great advance in fabrication of functional upper-extremity prostheses followed World War II. Arm prostheses came to be made of plastic, frequently reinforced with glass fibres.
The below-elbow prosthesis consists of a single plastic shell and a metal wrist joint to which is attached a terminal device, either a hook or a hand. The person wears a shoulder harness made of webbing, from which a steel cable extends to the terminal device. When the person shrugs the shoulder, thus tightening the cable, the terminal device opens and closes. In certain cases the biceps muscle may be attached to the prosthesis by a surgical operation known as cineplasty. This procedure makes it possible to dispense with the shoulder harness and allows finer control of the terminal device. The above-elbow prosthesis has, in addition to the forearm shell, an upper-arm plastic shell and a mechanical, locking elbow joint. This complicates its use, inasmuch as there must be one cable control for the terminal device and another control to lock and unlock the elbow. The most complicated upper-extremity prosthesis, that used in cases of amputation through the shoulder, includes a plastic shoulder cap extending over the chest and back. Usually no shoulder rotation is possible, but the mechanical elbow and terminal device function as in other arm prostheses.

Learn MoreA metal hook that opens and closes as two fingers is the most commonly used terminal device and the most efficient. After World War II the APRL hand (from U.S. Army Prosthetic Research Laboratory) was developed. This is a metal mechanical hand covered by a rubber glove of a colour similar to that of the patient&#;s remaining hand. Many attempts have been made to use electrical energy as the source of hook or hand control. This is done primarily by building into the arm prosthesis electrodes that are activated by the patient&#;s own muscle contractions. The electric current generated by these muscle contractions is then amplified by means of electrical components and batteries to control the terminal device. Such an arrangement is referred to as a myoelectrical control system.
Breast prostheses are used after mastectomy. External prostheses may be worn, but surgical reconstruction of the breast, involving implantation of a prosthesis, became increasingly common from the s.
