What is prosthetic alignment?

Alignment of a prosthesis is defined as the position of the socket relative to the other prosthetic components of the limb. During dynamic alignment the prosthetist, using subjective judgment and feedback from the patient, aims to achieve the most suitable limb geometry for best function and comfort.

What are the components of an above the knee prosthesis?

An above-knee prosthesis (also called a transfemoral prosthesis) will typically consist of a custom-made socket, a knee, a pylon, a foot, and some means of suspending the prosthesis to the body.

What is the TKA line?

A transfemoral (AK) prosthesis whose TKA line passes in front of the knee joint axis is inherently stable. A transfemoral (AK) prosthesis whose TKA line passes through the knee joint axis is less stable, but affords the wearer more voluntary control over knee function.

What is static and dynamic alignment?

Static alignment gives us the opportunity to correct issues such as soft foot, gross misalignment and to bring the system to within specifications. Dynamic alignment is the condition of the machinery during sustained operation.

What is above knee prosthesis?

An above-knee prosthesis includes a socket, knee joint, ankle joint, and foot components. You will receive a temporary prosthesis at first while your residual limb continues to heal and shrink/shape over several months of healing. The prosthesis will be modified to fit as needed over this time.

What are the elements of dynamic alignment?

DYNAMIC ALIGNMENT To be successful over time, four elements need to be aligned: the market, strategy, culture and leadership. The pre-requisite for aligning with the market is to understand and be able to define customer’s fundamental needs and buying behaviours – as it is these that ultimately drive sales and margin.

What is a static alignment?

Static alignment is the condition of the machinery at rest (think of the alignment we perform when the equipment is first installed). Static alignment gives us the opportunity to correct issues such as soft foot, gross misalignment and to bring the system to within specifications.

What is the difference between a prosthesis and a prosthetic?

The term “prosthetic” is also used as an adjective to describe items. Prosthesis: While prosthetics refers to the science of creating artificial body parts, the artificial parts themselves are called prosthesis. One piece is called a prosthesis, but multiple pieces are called prostheses.

What are the principles of above knee alignment?

THE PRINCIPLES OF ABOVE-KNEE ALIGNMENT MEDIOLATERAL STABILITY When one watches the walk of a typical above-knee amputee, two characteristics of gait often are particularly apparent. First, sidesway, i.e., lateral movement of the torso from side to side, is exaggerated.

Which is the correct way to align a prosthetic limb?

There are several differing methods of aligning a prosthetic limb. The method we will explain involves four stages; stump position, bench alignment, static alignment and dynamic alignment. In our understanding, all prosthetics should start from the body.

What is the weight bearing line in above knee prosthesis?

The Weight-Bearing Line One of the most common terms used by the prosthetist in the fitting and alignment of an above-knee prosthesis is the “weight-bearing line.” It serves as the guide for many phases of setting up the prosthesis, but its exact position is subject to considerable difference of opinion.

How does the C-Leg 4 above knee prosthetic leg work?

The gyroscope and acceleration sensors allow the position and acceleration of the C-Leg in space to be measured. Prosthetic Control is based on motion analysis and additional force determination. Integrated Bluetooth® technology permits straightforward communication with the joint.
