1

Reasons for LE Prosthetics:

Disease 70% vascular related
Trauma 22%
Congenital birth defects 4%
Tumors 4%

2

Check Socket or Diagnostic Socket

A transparent socket used to aid in assessing prosthetic fit.

3

Definitive Prosthesis

A prosthesis that is intended for long term usage, comfort, fit, cosmetic appeal and durability. Usually fit once the residual limb stabilizes.

4

Pistoning

refers to the residual limb moving up and down within the socket while walking

5

Preparatory Prosthesis

Initial prosthesis that may or may not include definitive components. It is intended for temporary use to allow the patient 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

6

Socket liner

soft interface used between the hard socket and residual limb. These can be made of various types of gel, socks or soft foams

7

Suspension Sleeve

an elastic tube made of varying materials that is first pulled over the outside of the prosthesis and then rolled up onto the thigh once the prosthesis is put on

8

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

9

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

10

Ischial containment socket

In some amputation cases, usually those of the HP or HD, this socket is used to
support the ischium

11

multiaxis foot

The multi-rotational axis allows for inversion and eversion of the foot, and it is effective for walking on uneven surfaces.

12

pylon

A rigid structure, usually tubular, between the socket or knee unit and the foot that provides a weight bearing, shock-absorbing support shaft for the prosthesis

13

suction socket

Mainly for use by AK level amputees, this socket is designed to provide suspension by means of negative pressure vacuuming. This is achieved by forcing air out of the socket through a one-way valve when donning and using the prosthesis. In order for this type of socket to work properly, the soft tissues of the residual limb must precisely fit the contours of the socket. Suction sockets work very well for those whose residual limbs maintain a constant shape and size

14

Apply post-operative protector:

0-4 weeks

15

Incision fully healed; cast for prosthesis

5-9 weeks

16

Sutures removed; limb shaping

3-5 weeks

17

Pre-prosthetic training period from presurgery to temporary device

0-2 weeks (could start before)

18

Ongoing therapy and prosthetic adjustments

4 months-6/7 months

19

Receive permanent prosthesis

6/7 months-1 year

20

Primary post-operative concerns:

Protection of residual limb
Compression-reduce post surgical edema
Maintenance of ROM
Pain Management- Pain vs Phantom pain/sensation
Maintain Strength and cardiac reserves

21

Types of protection for residual limb:

simple splint
post operative cast
removable post operative cast
weight-bearing post operative device

22

Post-op evaluation

History
Living situation
Support network
Work
Goals

23

Tubular Gauze

Used for bulbous, sensitive limbs
double layering of material
same advantages and disadvantages as ace wrapping
uniform compression

24

Prosthetic Shrinker

Compression sock that is used to help control swelling in the residual limb and help shape the limb in preparation for prosthetic fitting

25

Prosthetic Socks

Socks of varying thicknesses or ply. The higher the ply number, the thicker the sock. They allow a patient to manage small volume changes in limb size and add to the comfort of prosthesis. They can be made of different materials, including wool, silicone and synthetic fibers

26

Compression garments:

ace wrapping
shrinkers
post operative casts

27

Who are our patients?

60% are 45 years or older
85% lose limbs to diabetes or related vascular disease
Multiple chronic health concerns
Deconditioned, Flexion contractures, Overweight

28

What determines the
prosthetic Rx?

Functional ‘K’ level
Physical Concerns
Vocational and Leisure Activities
Cognitive skills
Home environment / distance from prosthetic center
Insurance Coverage

29

Physical Concerns of prosthetic Rx?

Level of amputation
Disease pathologies
Body weight
Skin integrity

30

Functional Level 0

no ability or potential for weight bearing or transfer
