Terminology Flashcards
Check socket / diagnostic socket
A transparent socket used to aid in assessing prosthetic fit.
Definitive prosthesis
A prosthesis that is intended for long term usage, comfort, fit, cosmetic appeal & durability. Usually fit once the residual limb stabilizes.
Pistoning
Refers to the residual limb moving up & down within the socket while walking.
Preparatory Prosthesis
Initial prosthesis that may or may not include definitive components. It is intended for temporary use to allow the pt to begin therapy for gait training. It is expected that it will need to be replaced within 3-9 months due to changes in the residual limb.
Suspension sleeve
An elastic tube made of varying materials that is first pulled over the outside of the prosthesis & then rolled up onto the thigh once the prosthesis is put on.May be lined with Neoprene, Latex, or Gel. Not durable. Creates negative pressure seal.
Socket liner
Soft interface used between the hard socket & residual limb. These can be made of various types of gel, socks or soft foams.
C-leg
The Otto Bock C-Leg features a swing and stance phase control system that senses weight bearing and positioning to provide the knee’s microprocessor information about the amputee’s gait, thus promoting smoother ambulation. The outer shell houses a hydraulic cylinder, microchip, and rechargeable battery.
Energy Storing Foot
A prosthetic foot designed with a flexible heel. The heel stores energy when weight is applied to it and releases this energy when weight is transferred to the other foot.
Ischial containment socket
In some amputation cases, usually those of the HP or HD, this socket is used to support the ischium.
Multiaxis foot
The multi-rotational axis allows for inversion and eversion of the foot and is effective for walking on uneven surfaces.
Pylon
A rigid member, usually tubular, between the socket or knee unit and the foot that provides a weight bearing, shock-absorbing support shaft for the prosthesis.
Suction socket
Mainly for use by AK level amputees. Designed to provide suspension by means of negative pressure vacuuming, which is achieved by forcing air out of the socket through a one-way valve when donning and using prosthesis. Soft tissues of the residual limb must precisely fit contours of the socket. Work well for those whose residual limbs maintain a constant shape & size.
Levels of LE Amputation
Hemi-Pelvectomy Hip Disarticulation Trans-Femoral (AK) Knee Disarticulation Trans-Tibial (BK) Symes Partial Feet
Prosthetic Shrinker
Compression sock used to help control swelling in the residual limb & help shape the limb in preparation for prosthetic fitting
Myodesis
- Suturing muscle to bone
- preferred for transfemoral amputation
