Getting The Right Fit For Your Prosthetic
Now that your doctor has prescribed a prosthetic leg, your journey begins. It may feel overwhelming to start the process because you are new to it. Finding out how the prosthetic leg works is a good way to start.
Prosthetic legs are made of materials that are meant to last, are durable, and lightweighttypically, plastic is a commonly used material. The place where you were amputated determines if the leg has ankle joints or a knee that functions. Your residual limb fits snugly in the socket of the prosthesis because the socket is a mold of your residual limb.
The prosthesis attaches to the body with the suspension system. Vacuum suction, sleeve suction, and distal locking are different options for the suspension system. To find out which is the best option for you, it is important to work with your prosthetist.
Not Everyone Benefits From A Prosthetic Leg
While many people with limb loss do well with their prosthetic legs, noteveryone is a good candidate for a leg prosthesis. A few questions you maywant to discuss with your doctor before opting for a prosthetic leginclude:
- Is there enough soft tissue to cushion the remaining bone?
- How much pain are you in?
- What is the condition of the skin on the limb?
- How much range of motion does the residual limb have?
- Is the other leg healthy?
- What was your activity level before the amputation?
- What are your mobility goals?
The type of amputation can also affect yourdecision. Its generally easier to use a below-the-knee prosthetic leg thanan above-the-knee prosthesis. If the knee joint is intact, the prostheticleg takes much less effort to move and allows for more mobility, explainsKeszler.
The reason behind the amputation is also a factor, as it may impact thehealth of the residual limb. Your physical health and lifestyle are alsoimportant to consider. If you were not very active and lost your leg due toperipheral vascular diseaseordiabetes, for example, you will struggle more with a prosthesis than someone whowas extremely active but lost a limb in a car accident.
When it comes to amputation, each person is unique. The decision to moveforward with a prosthesis should be a collaborative one between you andyour doctor.
To get the right type and fit, its important to work closely with your prosthetist a relationship you might have for life.

Recovering After An Amputation
After surgery, you’ll usually be given oxygen through a mask and fluids through a drip for the first few days while you recover in a ward.
A small flexible tube ) may be placed in your bladder during surgery to drain urine. This means you will not need to get out of bed to go to the toilet for the first few days after the operation. You may be given a commode or bedpan so you can also poo without having to get up to use the toilet.
The site of the operation may be painful, so you’ll be given painkillers if you need them. Tell a member of your care team if the painkillers are not working, as you may need a larger dose or a stronger painkiller. A small tube may be used to deliver local anaesthetic to the nerves in the stump to help reduce pain.
Your physiotherapist will teach you some exercises to help prevent blood clots and improve your blood supply while you’re recovering in hospital.
Triton Harmony By Ottobock
Your life. Your way. Taking part in everyday and professional life, being active in leisure time, doing sports. Taking on challenges, but also experiencing normality with family and friends. All this stands for quality of life.
In the development of new technologies, nature is the best model: That is why the anatomy of the human foot is reflected in the characteristic, triangular curved shape of the Triton.
The Triton product line offers a selection of prosthetic feet to meet the demands of highly active users. Their outstanding dynamic response and flexibility support mobility at the highest level in everyday life and for recreational sports. For a self-determined life.
A Model Of The Residuum
Kinematic and kinetic components of the model are illustrated in Figures 68. The model is a planar open chain of six weightless rods: two feet oflengths lf1 and lf2 twoshanks ls1 and ls2 and twothighs lt1 and lt2. Anglesbetween these elements and the vertical are fi,si and ti , respectively .
Normal and prosthetic gait synergies.
It is assumed that center of mass is located at the central joint,simulating projection of both hip joints. Step length L and heightH of the COM are given by Equations :
There are certain anthropomorphic restraints on the values of the 14parameters. When 11 of them are specified, the other three can be calculated fromEquations . Feet, shanks andthighs are recommended to be paired-equal length and should not be consideredvariables, but constants, which reduces the number of undetermined parameters tofive. Additionally, two constraints were derived based on gait analysis dataregarding stance events.

The effect of the resistive moment Ma =F×r onresiduum-socket interface in transtibial amputees is simulated inFigure 8, where couple forces±F are applied from the socket to the residuum. Theforces ±F provide normal stresses on the residual limb inaddition to shear stresses derived from the axial load as explained by Pearson.

How Much Does A Prosthetic Leg Cost
The average price of a prosthetic leg is greatly influenced by the type of device, with a wide range to choose from starting with a basic one and up to the computerized version. Also, the amputation level must be considered when talking about the costs.
Depending on your health insurance policy you might have to pay deductibles or co-pay. Health insurance companies should cover all prosthetic legs in some way or another. However, there are situations when only specific types of legs are covered and the patient must meet certain health terms. Before signing any agreement with a doctor and proceeding to have a prosthetic leg talk with your health insurance company.
The price of a basic prosthetic leg is around $8,500 without insurance. Also, patients without insurance would pay more than $121,000 for an advanced computerized prosthetic leg that is controlled by muscle movements.
In the table below you will find the average prices for some of the most common types of prosthetic legs.
|Type of Prosthetic Leg|
|Special hydraulic and/or mechanical assistance for better control||$25,000 to $50,000|
According to the Hospitals for Special Surgery, the average price of a new prosthetic leg is anywhere between $5,500 and $51,000. However, even the most expensive models must be replaced every three to five years as these get worn out during the time.
How To Use Your Prosthetic Leg For 100% Mobility
If youâve recently gone through amputation or your surgery is around the corner, you are likely considering what life would be like with a prosthetic leg. Prosthetic legs, or prostheses, are designed to help those who have undergone a leg amputation get around with ease. They mimic both the function and, in some cases, the appearance of a human leg. Even with a prosthetic leg, some patients still require the help of a cane, walker, or crutches to get around.
If youâre looking for additional information to help you make your decision about whether or not a prosthetic is right for you, our team at PrimeCare Orthotics & Prosthetics can help answer your questions.

Options For Using A Prosthetic Leg To Improve Mobility
When you consider starting to use a prosthesis, it is important that you understand that it is first as to be approved by a doctor.Before surgery, your doctor will examine your muscle strength, balance, and range of motion.Before and after the amputation procedure, the doctor, in collaboration with other staff members in your medical care, will assess your general health and closely examine medical problems that may involve additional physical stress and physical injury from diseases such as diabetes that prevent the possibility of using the prosthesis.
In addition, your mental health, energy levels, functionality and resources in your home will also be evaluated for recovery.If a prosthesis is suitable, the doctor will provide you with a prescription.The decision to continue with this option or not depends on you.
On Becoming An Amputee Do You Get A Leg Straight Away
After amputation the residual limb can be very sensitive. Physiotherapists and doctors advise getting up and walking as soon as possible to build up strength and halt swelling.
To achieve this, amputees get their first taste of artificial limbs when using an inflatable walking aid designed for partial weight-bearing. The residual limb goes in a cage-like device which is then pumped full of air to hold it in place.
This allows new amputees to take their first steps and find out what wearing a prosthetic leg feels like while holding on to the parallel bars at first. Many say that when they first saw the device, known as a Pneumatic Post-amputation Mobility Aid, they thought it looked like an old-fashioned device from the First World War.

Can I Wear Them In The Shower
Many components in a prosthetic leg are sensitive to moisture. Therefore most amputees take their legs off when showering. This is because it is not good for them to get wet but also because it is extremely important to keep stumps clean.
Some amputees prefer to do water sports or swim with their prosthetics on. This may be for practical reasons – ease of getting into a swimming pool or walking into the sea for example – or for aesthetic reasons as some amputees say they feel more self-conscious with their prosthetics off.
Solutions exist for this: there are waterproof airtight covers which fit on over the leg and keep the prosthetic protected. Or, there are limbs available which are more suited to going in the water.
If on a waterproof leg the wearer wants “cosmesis” which makes the leg look lifelike, it’s possible but they fill up with water. To counteract this a hole is put in the back of the leg and when exiting water the build-up simply trickles out.
You Already Have A Prosthetic You Still Need The Iwalk Crutch
The iWALK Crutch isnt just a transitional device for recovering below knee amputees. It is just as or even more useful as a back up to your permanent prosthetic.
The iWALK Crutch can be used anytime you dont want to hassle with your prosthetic. Heres what you need to know about the iWALK Crutch
The iWALK Crutch is the only device that enables you to be hands-free. You can walk in comfort and with stability. No more worrying about stairs and lack of space with a wheelchair and the instability of crutches!
Its a cinch to put on and take off some say less than 5 secondsMany iWALK Crutch below knee amputees use their iWALK to go to the bathroom in the middle of the night. No more crawling!
In addition, after a long day of wearing your prosthetic, you are ready to take it off. Before iWALK Crutch amputees tended to hop, crawl, or crutch around their house after removing their prosthetic for the day. iWALK Crutch enables below knee amputees to easily walk around the house without worrying about putting their prosthetic back on.
One BKA explained, With the iWALK it only took a few seconds to be back to normal.

Getting Used To A Prosthetic Leg Isnt Easy
Learning to get around with a prosthetic leg can be a challenge. Even afterinitial rehabilitation is over, you might experience some issues that yourprosthetist and rehabilitation team can help you manage. Common obstaclesinclude:
- Excessive sweating , which can affect the fit of the prosthesis and lead to skin issues.
- Changing residual limb shape. This usually occurs in the first year after an amputation as the tissue settles into its more permanent shape, and may affect the fit of the socket.
- Weakness in the residual limb, which may make it difficult to use the prosthesis for long periods of time.
- Phantom limb pain could be intense enough to impact your ability to use the prosthesis.
The Importance Of Getting A Prosthetic Knee
Artificial body parts such as prosthetic arms and artificial limbs are transforming the lives of people who experienced serious injuries. And for many of these individuals, a prosthetic knee or leg is an essential part of their body.
These basic devices are used to replace missing body parts, and they can range from simple hand-held crutches to sophisticated computer-controlled bionic limbs.
There are 6 types of leg amputations. They include:
Regardless of which type of amputation you have the prosthesis typically consists of a metal or carbon-fiber framework, a hydraulic or pneumatic joint, and a flexible socket that attaches to the residual limb. In some cases, the prosthesis may also include a sensory feedback system that allows the user to feel pressure and temperature changes. In addition, many prosthetic knees now offer computer-controlled functionality, allowing users to adjust the amount of flexion and extension based on their needs.
Prosthetic knees are designed to provide improved mobility and function for amputees.

What You Should Know Before Getting A Prosthetic Leg
Prosthetic legs, or prostheses, can help people with legamputationsget around more easily. They mimic the function and, sometimes, even theappearance of a real leg. Some people still need a cane, walker or crutchesto walk with a prosthetic leg, while others can walk freely.
If you have a lower limb amputation, or you will soon, a prosthetic leg isprobably an option youre thinking about.Amputee rehabilitation specialist Mary Keszler, M.D., shares a few considerations you should take into account first.
Can You Take The Stairs
Ankle joints are at a right-angle in most prosthetics, a bit like tensing your feet up. Because of this, walking downstairs can be tricky, or painful, and can jar the remaining part of your leg. Going up and down hills or slopes pushes amputees forward and inclines push the prosthetics backwards meaning that as much weight must be put onto the front of the foot as possible. As this affects centre of gravity, some amputees may have to take extra care to stay balanced.
Robotic ankles are being developed which allow the ankle joint to move from side-to-side as well as up and down in a more natural way.

The Key To The Success Of The Prosthesis
Ideally, you will work with the same prosthetic specialist for the long-term, so your mutual relationship should be carried out comfortably with the best level of communication.
While your prosthesis specialist needs to know how to listen and communicate well, remember that effective communication is two-sided.
Fill out your part by providing detailed information that the expert needs to work with you successfully.Establishing a long lasting relationship between you is key to successful use of the prosthesis.
Prosthetic Leg Manufacturers Relationship
POSI is privileged to have an excellent working relationship with many of the component manufacturers, such as Ossur and Ottobock. As new lower limb prosthetic technology becomes available, POSI is often chosen as a Beta test site. Testing new componentry with patients allows us to give feedback to the manufacturer before the final product goes to market. Based on our success and highly functional patient population we have been chosen to sit on multiple advisory boards such as Ossur and OttoBock.

Donning And Doffing Of Liners And Sockets
Donning a prosthesis refers to the application of a prosthetic device, doffing refers to the act of removing a prosthetic device.
There are many different types of prostheses available and the process of donning and doffing each is different. You will individually need to become familiar with the types of prosthesis that you use but these videos below provide some insight into donning and doffing socks, liners and prosthetics:
Pressure Tolerant And Pressure
The socket applies external forces over the surface of the residual limb. The amount, the location of their application and the means that control those forces contributes to the impact the prosthesis has on mobility, function, and acceptance of the device. Pressure distribution over a greater surface diminishes the load and provides more comfort during the use of prosthesis.
Although the majority of the stump areas are considered as pressure tolerant, some are very sensitive and cannot support any pressure. Sockets designs should allow forces to be distributed over as large a residuum surface area as possible and should be applied as evenly as possible over pressure-tolerant areas. These pressure-tolerant areas might turn red with pressure, that will subside when the prosthesis is taken off, but no skin breakdown occurs. Pressure-sensitive areas have a high probability of skin breakdown. No redness should occur in the pressure-sensitive areas. Knowing these areas will help the therapist to know where some redness is normal in a properly fitted socket. When redness occurs at pressure-sensitive areas the therapist should consult with the prosthetist.

Attention: Very short TT stumps are insufficient for providing adequate control over the prosthesis and supporting the body weight. Nevertheless, the quality of the stump is more important than its length.
Below we describe some common TT and TF socket designs.
