Lower limb prostheses are devices that can be used in place of amputated lower limbs of the body, from the hips down to the feet. There are hundreds of foot, ankle, and knee prosthetic systems to choose from when it comes to lower limb prostheses. The patient and the prosthetist work together to evaluate all the different joint and foot components of a prosthetic device. Together, they decide which system provides the best safety, balance, function, and walking efficiency for your lower limb loss.
Many lower limb prostheses are endoskeletal, which means they are adjustable. Endoskeletal prostheses have a central inner skeletal structure. They are usually covered with a soft synthetic skin material and designed in the shape of the limb. The adjustability of lower limb prostheses allows us to refine the range of motion for foot, ankle, or knee systems. Whether you have a prosthetic foot, ankle, or knee, we can help optimize functions (such as walking) without you having to expend unnecessary energy.
Adjustable lower limb prostheses can provide rotary motion lost from amputations above the ankle. This is particularly beneficial in instances when the limb must rotate while bearing weight, such as when playing golf or baseball, as well as other non-sport activities. Additionally, people who like to wear shoes with varying heel heights (sneakers or flats one day, cowboy boots or high heels the next!) can choose a prosthetic ankle that adjusts to different heights.
There are 3 general types of lower limb prostheses:
- Ankle and Foot Prostheses
- Knee Prostheses
- Sport-specific Prostheses
Ankle and Foot Prostheses
Ankle and foot prostheses can include hydraulic systems that reduce high-impact forces. Some of these may even automatically adjust to any rhythm changes.
These prostheses can also include microprocessor-controlled systems that control function in real-time based on the person’s motions or their surroundings. There are passive devices, as well as those that provide active support, that help to reduce energy expenditure while walking.
Knee prostheses can be passive, body-powered, pneumatic, or hydraulic systems with either a single or multi-axis joint.
There are also microprocessor-controlled knee prostheses that can help reduce fall risks. By lowering the amount of effort people need to use while walking, it offers greater control, safety, and stability.
Sport-specific foot and ankle prostheses are designed to achieve the highest level of physical performance. While most people find them effective for multiple sports, many others also find them beneficial for recreational activities.
These devices can be customized for specific activities such as climbing, long-distance running, swimming, skiing, or sprinting. Socket and suspension adjustments are critical for athletes, as they often experience muscle atrophy and body mass fluctuations.
People with partial-foot amputation may expend less energy walking than those with higher amputation levels. Some people may retain lower limb length, and some may have a residual foot that can still provide a natural, load-bearing support. Many people with partial-foot amputations may stand and walk short distances (such as transferring in and out of bed, or walking to an adjacent room) without prosthetic devices.
One partial-foot prosthesis can be a silicone slipper-type device that allows simple action and ankle motion at slow and medium speeds.
People who like to do more vigorous activities (such as jogging, speed-walking, climbing stairs, or running) can use a semi-rigid plastic socket device that covers the residual foot and ankle, and extends up to the inner region of the kneecap.
Syme Ankle Disarticulation Prostheses
Some amputations may retain a thick heel tissue pad that can still provide weight-bearing capability. Although limb length may be slightly shortened, people may still be able to stand and walk short distances.
A custom-modified prosthesis for Syme amputations can reduce the prominence of the typical bulbous end. It is a fairly simple prosthetic fitting, and results in a more streamlined ankle appearance.
Transtibial (Below-Knee) Prostheses
A properly-fitted and aligned below-knee prosthetic device may help a person function at a high level, often without visible walking difference. Amputation that maintains some residual limb length just below the tibial tubercle can maintain the quadriceps insertion. This provides better function than through-knee or above-knee amputation.
There are various below-knee prostheses that can help improve knee connectivity, comfort, and walking stability. These include a total-surface-bearing socket with a primary flexible socket, or a semi-rigid retaining socket with vacuum volume management and suspension. Vacuum and other methods of suspension can be employed in various effective ways, whether mechanically or electrically.
Transfemoral (Above-Knee) Prostheses
Socket designs for transfemoral prostheses can be rigid, with flexible panels to accommodate muscle expansion and fluctuations. The suspension system can include a mechanical strap, integrated suspension pin, suction, or vacuum.
Hip prostheses weigh significantly greater than other devices, and require greater care in regard to socket fit and suspension. Energy expenditure may also be greater, and walking speed may be less. There are challenges to the longevity of hip prostheses because they are often rejected by people’s unrealistic expectations.
In order to achieve a successful outcome with hip prostheses, there needs to be a realistic understanding of their limitations and challenges. Successful long-term use of a hip prosthetic device depends greatly on a person’s level of motivation, balance, core strength, coordination, and ability to support body weight on the residual limb.
