Frequently Asked Questions — Prosthetics
A prosthesis is not bionic. It is an artificial replacement for a missing limb or part of a limb. Although a prosthesis is never as natural as your own limb, it can help you to do many things quite effectively if you are willing to combine your energy and willpower into learning how to use it. The most important aspect of success is working with your doctor, prosthetist and therapist to address all of your concerns, and then to work with them on the processes of design, fitting and training, which are required to be a successful user.
Depending on the level of your amputation, physical ability and functional needs, each prosthesis will be somewhat different. If you desire a “cosmetic look,” prosthetic supplements are available. But, for most standard prostheses, they are comprised of conventional component parts attached to a socket that fits over your residual limb.
The majority of people who lose a limb can get back to a normal mode of functioning within a few to several months, depending on the location of the amputation as well as physical ability. How well they function depends primarily on their goals along with timely, comfortable prosthetic fitting, good follow-up care, and a “can do” attitude from themselves as well as their medical team.
Generally, you should be ready for prosthetic measurements and fitting a few weeks after surgery, when the wound is healed and the tissue swelling is decreased. Then you will be ready for prosthetic measurements and fitting. This process can be easily attained with exercise and rehabilitation. During this stage, your medical team also will be concerned with maintaining proper shape of the residual limb, as well as increasing overall strength and function. Fitting is usually stress-free and involves several steps to create a unique prosthesis for you.
Follow-up is as important as the initial fitting. You will need to make several visits for adjustments with the prosthetist as well as training with a therapist. They can help you ease pressure areas, adjust alignment, work out any problems, and regain the skills you need to adapt to life after limb loss. Tell your prosthetist if the manufactured limb is uncomfortable, too loose or too tight. Ask questions about things you need or want to do. Communicate honestly about your needs. The more you communicate with your prosthetist and therapist, the better you will be able to succeed with a prosthesis.
Depending on your age, activity level and growth, the prosthesis can last anywhere from several months to several years. In the early stages after limb loss, many changes occur in the residual limb that can lead to shrinking of the limb. This may require socket changes, the addition of liners, or even a different device. Later on, increased activity level and desire for additional function can necessitate a change in the prosthesis or its parts. Once you are comfortably adjusted and functioning at the desired level of activity, the prosthesis needs only minor repairs or maintenance and can last for an average of three years.
Learning to use a prosthesis is a tough job. It takes time, great effort, strength, patience and perseverance. You will do best to work with a therapist while learning how to handle the new device. Much like learning how to operate a car, you will need guidance on how to:
- take care of the prosthesis
- put on (don) and take off (doff) the prosthesis
- walk on different types of surfaces, including stairs and uneven terrain
- handle emergencies safely, including falling down and getting up again
- perform daily activities at home, at work and even in a car
- investigate new things you may be uncertain of, including sports and recreational activities.
There is a lot you can and must do to be able to use a prosthesis and use it well. The top priorities are:
- working through the feelings about losing a limb and deciding how to rebuild your life after amputation
- exercising to build the muscles needed for balance and ambulation
- preparing and taking care of your residual limb to attain a proper, sound shape for the prosthesis
- learning proper body positioning and strengthening, to maintain tone and prevent contractures.
Some people elect not to use a prosthesis, relying exclusively on mobility devices. However, with a prosthesis, the use of crutches or a wheelchair depends on several factors including level of amputation, whether you have a single or bilateral amputation, and your respective level of balance and strength. Most amputees have a pair of crutches for times when the limb is off, including nighttime trips to the bathroom, showering, participating in certain sports, and to help if problems arise that may require leaving the prosthesis off for any length of time.
Plan on making follow-up visits to your prosthetist a normal part of your life. Proper fit of the socket and good alignment will insure that the prosthesis is useful to you. Prostheses, like cars, need regular maintenance and repair to continue efficient functioning. Small adjustments can make a big difference.
Yes, things can happen that will require repair or replacement, so it’s a good idea to know about warranties and what to expect from your prosthetist. Get small problems with your prosthesis taken care of promptly. There is no benefit to waiting until something falls apart or causes you serious skin breakdown. If you wear a prosthesis too long when it needs repairs or replacement, you can do harm, not only to your residual limb, but also to other parts of your body. Strain on other muscles, especially in your back and shoulders, will affect posture in addition to performance of the device and energy needed to use it. Early prevention is more valuable than long-term treatment.
