Q

ROM to prevent flexion contractures, particularly of the hip and knee. Prone position every 3-4 hours.

A

Post-op Exercise

20
Q

Sitting promotes ___ flexor and ____ flexor contractures.

A

Hip (TT, TF), Knee (TT)

21
Q

TF also a risk for _____ contracture.

A

Abduction

22
Q

Supine resting position promotes hip ____ contracture.

A

ER (TT, TF)

23
Q

Restore foot function, simulate shape of missing foot segment.

A

Partial Foot Prostheses

24
Q

Pt. bears most of weight on the heel. Riding plate added into prosthetic foot. To aid late stance, bottom of the prosthesis or sole of the shoe may have a rocker bar.

A

Transmetatarsal Amputation

25
Q

Adaptation to uneven surfaces, shock absorption, limb length adjustments, stabilization of the knee, limb shortening during gait.

A

Functions of Prosthetic Feet

26
Q

Wooden keel and polyurethane foam heel wedge, common for TT and TF amputations, no moving parts, simulates PF as the heel wedge compresses at heel strike.

A

Solid Ankle Cushion Heel (SACH)

27
Q

Allows limited motion for PF/DF.

A

Single Axis Foot

28
Q

Graphite laminate heel and forefoot. Stored energy from loading the toe is returned at push off. 20% energy savings over SACH foot.

A

Energy Storing Feet Flex-Foot

29
Q

Wool or synthetic. Severe to add volume within the socket as limb volume increases. Socks come in many sizes and thickness from 1-6 ply. Number and ply may be changed by patient depending on size of residual limb.

A

Stump Socks

30
Q

Used for TT amputations. Uses total contact (force exerted over entire residual limb), has specific areas of weight bearing and non weight bearing.

A

Patellar Tendon Bearing (PTB) Socket

31
Q

Patellar tendon, medial flare of the ant. tibia, lateral aspect of limb, lateral surface of the fibula distal to the head, and popliteal fossa.

A

Weight Bearing Patellar Tendon Bearing (PTB) Socket

32
Q

Patella, tibial tubercle, crest of the tibia, distal end of tibia, fibular head, hamstring tendons, common peroneal nerve, and saphenous nerve.

A

Non-Weight Bearing Patellar Tendon Bearing (PTB) Socket

33
Q

New amputees often need to be taught to walk in some _____ throughout the stance phase, due to the alignment of the socket.

A

Knee Flexion

34
Q

Apply forces over the entire residual limb. No areas of relief except no weight bearing on ends of cut bones. Uses a liner.

A

Total Surface Bearing Socket

35
Q

Refers to the components and design features used to hold a prosthesis in place during ambulation and ADLs.

A

Transtibial Suspension

36
Q

Riveted to the medial and lateral walls of the socket, closes around the lower thigh. May result in pressure in the popliteal space.

A

Supracondylar Cuff

37
Q

Used with PTB. Removable wedge. Inserted by the amputee inside the medial wall of prothesis.

A

Medial Wedge

38
Q

Wedge maintains limb in place during both stance and swing phase. Allows amputee to remove the entire medial aspect of the socket.

A

Removable Medial Wall

39
Q

Usually when there is instability of the knee and uses knee hinges for support.

A

Thigh Corset and Knee Hinges

40
Q

Allows for no swing-phase flexion and provides complete stability. Pin allows amputee to bend knee in sitting. Primarily in geriatric patients.

A

Manually Locking Knee (Transfemoral)

41
Q

Most basic. Allows knee flexion during swing phase but must be stabilized by GRFs during stance phase. Amputee just use hip muscles to hold knee in full extension.

A

Single Axis (Constant Friction) (Transfemoral)

42
Q

Limited ambulatory. When weight bearing on prothesis, knee compresses the spring and contracts a syndical brake. This friction stabilizes the knee and prevents further motion. Impossible to flex knee during pressing until it fully unlocks and spring opens, releasing brake device.

A

Stance Control (Friction Brake) Knee

43
Q

Socket characterized by four distinct shaped proximal walls. Uses total contact. Sockets aligned in a few degrees of adduction and flexion.

A

Quad Fitting (Transferal Sockets)

44
Q

Partially encapsulates the tip of the ischium within the socket walls. Improves stability especially in those with short residual limbs.

A

Ischial Containment Designs (Transfemoral)

45
Q

Most secure option for suspension. Allowing little or no pistoning during swing phase. Maintain constant weight. Uses silicone sock over residual limb.

A

Vacuum (Suction) Transferal Suspension

46
Q

Uses when the skeletal contours are such that they can be used to stabilize the socket against displacement in swing phase.

A

Anatomic Suspension

47
Q

Adjustable and able to accommodate volume changes. Some pistoning is inevitable.

A

Strap Suspension
