BELOW-KNEE PROSTHETIC SOLUTIONS FOR THE CHARLOTTE, ROCK HILL & LANCASTER COMMUNITIES
A below-knee prosthesis, also referred to as a transtibial prosthesis, is an artificial limb that replaces a leg lost below the knee. For many individuals who have undergone limb loss, a prosthesis can be instrumental in improving mobility, functionality, and, for those who value it, appearance.
BELOW-KNEE PROSTHESIS COMPONENTS
Below Knee prostheses are made up of several, interconnected components working together to make the prosthetic device functional, durable, and comfortable for the user.
SOCKET
This is the part of the prosthesis that the residual limb fits into. The socket provides a base for the attachment of the components. It can be made of thermoplastic or silicone.
LINER
Liners provide a cushion between the residual limb and the hard socket of the prosthesis, protecting the skin, offering padding for comfort, and helping in holding the prosthesis.
PYLON
The pylon provides the necessary structural integrity to the prosthesis and attaches the bottom of the socket to the chosen foot. Typically, pylons are made of materials like titanium, stainless steel, or carbon fiber.
SUSPENSION
This secures the artificial limb onto your residual limb. There are different types of suspension. Neoprene or textile-type sleeves utilize friction to grab onto the thigh and top of the prosthesis. Occasionally, a belt or strap might be utilized to hold up the socket.
FOOT-ANKLE ASSEMBLY
There are various types of prosthetic feet and ankles available depending on an individual’s unique needs. The foot provides a base of support and is often designed for shock absorption. The ankle also plays a big part in facilitating a natural walking pattern.
COMMON MATERIALS USED
Carbon Fiber
Lightweight and durable, carbon fiber is often used for the foot and shank components.
Silicone and Gel
These materials are used to create socket liners, which offer comfort and cushioning.
Polyethylene, Polypropylene, and PVC
These are various plastics used in different parts of the prosthesis due to their durability.
Titanium and Aluminum
Both metals are lightweight and strong, making them ideal for the internal structure of endoskeletal prostheses.
Wood
Traditionally used in exoskeletal prostheses, wood offers durability and stability but is now largely replaced by lighter and more advanced materials.
THE FITTING PROCESS
Initital Assessment
A prosthetist will examine the shape, length, strength, and skin condition of the residual limb.
Second Appointment
Once the sutures have fully healed, the swelling subsides, and the limb is appropriately shaped, a plaster mold of the limb is taken. From this mold, a temporary plastic socket is crafted to check the fit.
Prelim. Prosthesis
A preparatory prosthesis is then designed to be worn over several months. As the limb undergoes changes in size, the prosthesis may require multiple adjustments.
Perminent Prosthesis
Once the limb stabilizes, a definitive prosthesis is introduced. Meticulous fine-tuning is vital for correct alignment. Regular check-ins and adjustments might be required as time progresses.
REHABILITATION EXPECTATIONS
Rehabilitation starts before the prosthetic limb is even fitted. The goal is to build strength, reduce the risk of any post-surgery complications, and prepare the client for the journey ahead. Post-surgery care will focus on healing and pain management.
When the prosthesis is ready to be fitted, the focus shifts to improving mobility, endurance, and overall function. Maximizing comfort and pain management also becomes a priority.
Initial training will cover learning to balance on the prosthesis and walk on even surfaces. Once the fundamental skills are down, there follows gait training and navigating stairs, slopes, and uneven terrains. Adjustments to the prosthesis will be made if see fit. Mobility and strengthening exercises will continue to be a big part of the rehabilitation process. If needed, continued support through community and vocational re-entry programs will be prescribed.
Regular appointments with the prosthetist are essential to ensure the prosthesis remains in good condition and fits well. Our team of doctors and therapists will have an active involvement in every step of the process.
