Lower Extremity Prostheses

A lower extremity prosthesis is made to withstand weight-bearing forces while allowing flexibility which will achieve a smooth walking pattern. Whether a new amputee or an experienced prosthetic user, the impact of walking has an effect on the residual limb and the overall body. When designing the prosthesis, the Prosthetist must consider patient stature, cognitive and physical abilities along with the activity it will be used for.

A prosthesis is constructed with materials resilient to daily impact while maintaining a lightweight feel to reduce fatigue. Combining shock absorbing materials with dynamic componentry increases comfort during daily activities, preserving the condition of the limb and overall health of the user.

The Prosthetist works with the user to ensure the artificial limb is fitting properly, while relying on biomechanical principles to optimize the fit. The elements of walking such as progression, standing stability and energy conservation are analyzed and deviations noted.

Technological advancements have brought about a variety of colors, materials, and parts available to make a prosthesis specialized for each individual. The purpose of the prosthesis may demand additional componentry which may affect the appearance of the prosthesis or increase maintenance or weight.

Lower Extremity Prostheses are categorized by the level of amputation:

  • Hip Disarticulation/Pelvectomy
  • Above Knee (trans femoral)
  • Below Knee (trans tibial)
  • Partial Foot

The Prosthetist must consider patient stature, activity level and functional goals when compiling the prosthetic blueprint which meets patient expectations while adhering to insurance guidelines. Click here to view pdf
