An exoskeletal prosthesis has the strength provided by an outer lamination, while the cosmetic cover is integral. An endoskeletal prosthesis offers more adjustable components but a less durable cosmesis. It consists of lighter materials like aluminum and titanium with interchangeable connectors, knees, and feet, allowing for alignment changes and improved function compared to an exoskeletal prosthesis.

1. L/L PROSTHETIC COMPONENTS
EXOSKELETAL V/S ENDOSKELETAL

3. PROSTHESIS
 An artificial device that replaces a missing
body part, which may be lost through trauma,
disease, or is a condition present at birth
(congenital disorder).
 Designed to mimic natural function, structure
& aesthetics of the limb being replaced.

4. HISTORY
• First prosthetic toe discovered on a mummy from Ancient Egypt
• 300 BC – First documented prosthetic leg made of bronze and iron
with a wooden core
• 1529 – Ambrose Paré: pioneered modern amputation surgery, 1536
produced a transfemoral prosthesis with fixed position, adjustable
harness, replaced iron with leather, paper and glue.
• 1800 – James Potts: wooden shank and socket, steel knee joint
• 1868- Gustav Hermann: replacement of steel with aluminium
• US Civil War
• World War II -----Modern day designs

5. EXOSKELETAL V/S ENDOSKELETOL
In the exoskeletal prosthesis, the strength is
provided by the outer lamination, andthe
shape or cosmesis (cosmetic cover) is an
integral part of the prosthesis. ...
Endoskeletal prostheses offer more component
options with more adjustability, but the
cosmesis is less durable.

6. PARTS

12. FOOT:-
• Restore contour of
foot.
• Absorb shock at heel
contact.

13. PYLON/SHANK:-
• Substitute for human
leg.
• Restores length and
shape.
• Act as a medium
between Socket & foot-
ankle assembly.
• Transmit body wt from
socket to foot.

14. ROTATOR:-
• The rotator allows for
360 degrees of rotation
below the component
at the push of a button.
• Cross leg sitting is
possible.

15. SOCKET ADAPTRS:-
• It connects socket to foot
through pylon/shin.
• Provides opportunity to do
alignment changes.

16. SOCKET:-
• The prosthetic socket,
essential point of
integration between human
tissue and replacement
limb, is most often also the
place where degree
of prosthetic success
is defined.
• It is the socket that accepts
and transfers to the residual
limb the stresses of weight-
bearing, suspension and
ambulation.

17. SUSPENSION:-
• The Suspension sleeve is a
device that offers comfort,
support and suspension of
your prosthesis.
• The sleeve functions by
cushioning your residual
limb and due to the
intimate fit, ‘grips’ the flesh
on your limb offering a
more intimate fit between
the socket and your leg.

18. COSMETIC COVER FAIRING:-
• Protects the internal parts
from damage & dust.
• Provides the contour of leg
as sound limb.

19. COSMETIC STOCKINGS:-
The Perlon stockings with
rubber band are intended
for the outer cosmetic finish
of modular knee
disarticulation prostheses
and transfemoral
prostheses.

21. Exoskeletal prosthesis has some
disadvantages:
• Heavy and cumbersome
• Alignment can not be changed after final finish.
• Does not provide efficient stance phase and
swing phase control
• Exoskeletal prostheses are not suitable for
through knee amputation
• Fabrication time for exoskeletal prosthesis is
much longer.

22. ADVANTAGE OF ENDOSKELETON
COMPONENTS
 Composed of lighter-weight materials like aluminum,
titanium, and graphite.
 Interchangeable connectors and other components such as
knees and feet.
 Components alignment facility.
 Endoskeletal prostheses offer more component options
with more adjustability.
 Offers improved function.
 cosmetically it has much better acceptability and restores
appearance to near normal.
 Time required for fitment of endoskeletal prosthesis is
much less.

23. Disadvantage
 Cosmesis is less durable.
