Indications for Amputation

Peripheral vascular disease
Diabetic limb disease
necrotising fascitis
trauma
infection
tumors
nerve injury
congenital anomalies

2

extended foot plate:

extended carbon fiber foot plate 
includes incorporation of a steel shank into the sole of shoe to allow normal toe off ambulation

3

What does spring steel shank do?

reproduces the action of longitudinal arch of foot during ambulation

4

toe filler:

custom molded foam pad or lamb's wool can fill the distal empty toe portion of the shoe
rigid rocker bottom sole

5

What does a Chopart amputation remove and save?

remove: forefoot and midfoot
save: talus and calcaneus

6

Benefit's of Syme's amputation:

Distal Weight Bearing
Longer limb=less energy loss
Can ambulate without prosthesis
Proprioception
Preservation of distal growth plate in children

7

Negative of Syme's amputation:

Wound healing
Compliance
Heel pad instability

8

Tibial length not feasible for fitting:

3.5 inches

9

Myoplasty suturing

Opposing Muscle sutured together
Muscle to soft tissue
Soft tissue to soft tissue
Transtibial amputation preferred

10

Main advantage of thru knee amputation:

creation of endbearing stump and preservation of distal femoral physes
long active lever arm

11

Suction socket:

provide suspension by means of negative pressure vacuuming.
achieved by forcing air out of the socket through a one-way valve when donning and using the prosthesis

12

Myodesis:

suturing of muscle bone

13

Myoplasty:

muscle is sutured to muscle and then placed over the end of the bone before closing the wound
patients with poor vascular health, the myoplasty technique is preferred

14

PFFD’s: Proximal Focal Femoral Deficits

Congenital defect of the proximal femur

15

Congenital defect of the proximal femur

absent hip
femoral neck pseudoarthrosis
absent femur
shortened femur

16

transradial optimum level:

junction prox 2/3 and distal 1/3

17

Transradial shortest level:

3cm below biceps insertion

18

Transhumeral optimum level:

middle third

19

Transhumeral shortest level

4cm below axillary fold

20

Transfemoral optimum level

middle third

21

Transfemoral shortest level

8cm below pubic ramus

22

Transtibial optimum level

8cm for every metre of height  (12cm

23

transtibial shortest level

7.5cm below knee joint

24

Transradial longest level

5cm above wrist joint

25

Transhumeral longest level

10cm above olecranon

26

Transfemoral longest level

15cm above knee joint

27

Krukenberg procedure

Separate radial and ulna rays distally
forming radial and ulna pincers capable of strong prehension and excellent manipulative ability

28

What are the three parts of the peripheral vascular system?

Arterial System

Venous System

Lymphatic System

29

Function of arterial system:

Carry oxygenated blood to the capillaries of the body organs.

30

Tunica Intima

endothelium, CT, basement membrane
