Nonarticulated is the most popular |
|
Name two types of Nonarticulated Feet. |
A.) SACH Solid Ankle Cushion Heel
B.) SAFE Stationary Attachment Flexible
|
|
SACH |
Solid Ankle Cushion HeelAbsorbs shockPermits Plantarflexion in early stance Heel cushion allows small amount of medial-lateral and transverse motion. |
|
SAFE |
Stationary Attachment Flexible Endoskeleton For uneven surfacesHas a "Play" Great range of medial-lateral motion permitted in rear foot.Inversion and Eversio |
|
Flet-Foot and Springlite Foot are.. |
Other nonarticulated feet for Athletes and Runners |
|
Name two Articulated Feet. Which one is most common? |
A.)Single-Axis Feet MOST COMMON
B.)Multiple-Axis Feet
|
|
Single-Axis Feet |
MOST COMMON A rear bumper Absorbs shock and controls Plantarflexion excursion. Does NOT allow medial-lateral or transverse motion. |
|
Multiple-Axis Feet |
Components move slightly in all planes to aid the wearet max contact with the walking surface no mater if its even or has irregularities.Heavier and less durable than single-axis. |
|
What material is the Single-Axis Foot and Multiple-Axis Foot made of? |
Single-Axis is made of Resilient material Multiple-Axis is made of Titanium material |
|
For the single-axis foot If softer on front allows what motion? If softer in the back allows what motion? |
Softer in the front for Dorsiflexion Softer in the back for Plantarflexion |
|
Shank is a Replacement of... Name the two types of Shanks. |
Your leg. Exoskeletal Shank and Endoskeletal Shank |
|
Consist of a central Aluminum or rigid plastic tube called Pylon usually covers with foam rubber. More natural in appearance. Can be adjusted and has more compartments. |
Endoskeletal Shank |
|
Sometimes called Crustacean, typically made of rigid plastic Less lifelike and do not permit changes in alignment of the prosthesis and are less frequent prescribed. |
Exoskeletal Shank |
|
How long does it take for a residual limb to stabilize? |
2 years |
|
The amputation limb fits into a plastic receptacle called? |
Socket |
|
Design to contact ALL portions of the amputated limb for maximum distribution of the load |
Transtibial Socket |
|
The socket is aligned on the shank in what slight motion? And for what? And prevents what? This motion facilitates contraction of what Muscle? |
In slight Flexion To enhance loading on the patellar ligament. Prevents Genu Recurvatum Flexion also facilitates contraction of the Quadriceps muscles. |
|
Socket is also aligned with a slight lateral lateral tilt to reduce loading on...and prevent |
On the Fibular head to prevent pressure on Peroneal Nerve. |
|
All individuals with LE amputation require a? |
Supply of clean socks of appropriate material, size and shape. |
|
Fabric socks are woven in various thinknesd, referred to as what? |
Ply |
|
Cotton socks are made in what plys and are least what? |
Least Allergenic Made in Two, Three and Five-Ply |
|
Wool socks (Expensive) Provide what? And made in what plys? |
Good cushioning, woven in Three, Five and Six |
|
When pt requires 15-ply of socks to achieve snug fit it should be.. |
Altered or Replaced by the Prosthestist. |
|
Suspensions |
Hold the prosthesis to the residue limb..holds it in place. |
|
Name 4 types of suspension and which is most used? |
Supracondylar Cuff (most used) Fork Strap Silicone Seath w/ pin Vacuum Assisted |
|
The Vacuum Assisted has what type of Shank? |
Endoskeletal Shank |
|
Transfemoral Prostheses |
Above Knee |
|
Foot-Ankle Assemblies and Shanks for Transfemoral |
SACH Single-Axis Foot Exoskeleton or Endoskeletal Shank may be used. |
|
Axis System two types |
Single-Axis Hinge Polycentric Linkage |
|
Single-Axis Hinge motion |
Bending and Extending |
|
Polycentric Linkage |
More complex Provides mechanical swing control and allows a single optimal walking speed. |
|
Transfemoral Socket |
Should be a total-contact receptacle to distribute load over the maximum area, thereby reducing pressure. |
|
Name three types of Transfemoral Sockets |
1.) Quadrilateral Socket 2.) Ishial Containment Socket 3.) ComfortFlex™ Socket |
|
Quadrilateral Socket (Transfemoral) |
Shape is Quadrilateral when view from above. |
|
Ischial Containment Socket (Transfemoral) slight sicket Flexion is desirable for what 3 reasons? |
1. To facilitate contraction of Hip Ext 2. To reduce Lumbar Lordosis 3. To provide a zone through which the thigh may be extended to permit the wearer to take steps of app equal length |
|
ComfortFlex™ Socket |
The carbon fiber frame provides structural support while intimately fit Flexible socket allows for m contraction and improved control of the prosthesis. |
|
Suction Suspension (Transfemoral) Refers to... |
The difference b/t pressure inside and outside the socket. |
|
Name the three types of suctions? |
Total suction Partial suction No suction |
|
Total Suction |
Completely held by suction |
|
Partial Suction |
A socket that is slightly loose may provide suction suspension combined w/ Axillary suspension, the socket has a valve. The pt wears one or more socks or a syntetic liner. Beacuse air enters the space between the sock's fibers, Axillary suspension is needed. Either a fabric Silesian Belt or a rigid plastic or metal hip jt and Pelvic Band |
|
No suction |
Th pt wears one or more socks and requires a Pelvic Band. |
|
Name three ways to care for Foot-Ankle Assemblies |
1. Avoid getting prosthetix foot wet 2. Avoid stepping in sand it may enter the cleft 3. Don't walk w/o a shoe |
|
Care for the Shank for Endoskeletal and Exoskeleton |
Endoskeletal (made of plastic) no direct heat Exoskeletal needs to be wiped only periodically w/ a dampened cloth. |
|
Care for knee unt of Transfemoral |
Call the prosthetist to tighten knee mechanism Lubricate the knee and ankle area if there's squeaking. |
|
Care for Plastic Sockets |
Wash with cloth dampened in warm water that has a very small amount of mild soap dissolved in it. |
|
Care for Socket Liners made of Polyethylene |
Wash by hand in tepid water with mild soap, rinsed, and air-dried overnight. No direct sunlight. |
|
Care for Leather Corsets |
Should be kept dry. Use of saddle soap will keep leather clean. |
|
Care for Transfemoral suction valve |
Should be brushed Daily to remove Talcum and lint, these may clog the tiny Aperture. |
