What is a prosthetic limb? The Basics Amputees Must Know

You may also have this question"If you have an amputation, will you have to sit in a wheelchair?" - This is the first reaction of many people when they hear the news of amputation. But in fact, modern prosthetic technology has developed to a very mature stage. Most amputees can stand and walk again, and even run, swim, and cycle after being fitted with prostheses and undergoing rehabilitation training. This article is your first step in understanding prosthetics.

1. What is a prosthetic limb? Prosthesis, also called prosthesis, is an artificial device used to replace missing limbs. It is worn on the residual limb (the remaining part of the limb after amputation) to help amputees restore some or most of their limb functions while improving their appearance. Prosthetics do not "treat" amputations, but function compensation - using artificial materials to simulate the movement functions of real limbs, allowing amputees to regain the ability to live independently. 2. Basic components of a prosthesis1. Socket This is the most important part of the prosthesis and the only part that is in direct contact with the human body. The socket is customized by a prosthetist-orthotist according to the shape of the amputee's residual limb and is placed on the residual limb. It is the connection interface between the prosthetic limb and the human body. An inappropriate socket can cause pain, skin damage, and affect the overall user experience. 2. LinerA silicone or foam sleeve placed outside the skin of the residual limb to cushion, protect and suspend. Common ones include silicone lining sleeves (such as Össur ICEROSS series). 3. The prosthesis bodyincludes joint components (knee joints, ankle joints) and end devices (prosthetic feet, prosthetic hands). This part determines the functional level and user experience of the prosthesis. 4. Connecting componentsA tubular structure or skeletal system that connects various components together, usually made of aluminum alloy or carbon fiber.

3. Main classification of prosthesesBy amputation site: Lower limb prostheses: including calf prostheses (transtibial), thigh prostheses (transfemoral), knee Disarticulated prostheses, hip disarticulated prosthesesUpper limb prostheses: including forearm prostheses, upper arm prostheses, wrist disarticulation prostheses, and shoulder disarticulation prosthesesAccording to functional type: Decorative prostheses: mainly restore the appearance, have limited functions, and are common in the hands Functional prostheses: provide actual sports functions, divided into mechanical, physical-driven, and myoelectric control typesSports prostheses: designed for specific sports, such as carbon fiber blade feet for running4. Editorial Discussion"Prosthesis is not a panacea, but combined with rehabilitation training, it can allow amputees to regain the initiative in life. The sooner they start to understand and intervene, the better the rehabilitation effect will be."Practical tips:· Start stump shaping and rehabilitation training as soon as possible after amputation to prepare for prosthetic fitting· Find a qualified and regular prosthetic fitting center, which will be evaluated by a certified prosthetist and orthotist· Do not buy "universal prosthetics" online - the socket must be customized, and universal products cannot be used safely· Don’t give up just because the price is high. Understand the local subsidy policies first. It may be more affordable than you think5. Under what circumstances are prostheses needed? Not all amputees must use prosthetics. The following conditions need to be evaluated together with doctors and prosthetists and orthotists: whether the length of the residual limb is sufficient to install a prosthetic limb; the healing condition of the skin of the residual limb; the general health condition (elderly people and those with weak cardiopulmonary function require special evaluation); personal activity needs and rehabilitation wishes. Summary1. Prostheses are functional compensation devices, not treatments, but they can significantly improve the quality of life of amputees2. The socket is the core and must be customized and cannot be left to its own devices3.
